Can you recommend me tubes which meet all these requirements:
They can be from any family. Whether you sell them or not. I can find on ebay if you want. Family or make doesn't matter. Just recommend the best for my purpose.
Neutral or slightly bright treble, shouldn't be warm. I don't need warm. Extremely crisp, better than rca clear top Super fast attack and prat, better than rca clear top Super clean, super clear and super transparent, better than rca clear top Forward mids or very forward mids or slightly forward mids If possible, thumping bass as well. And if possible strong bass. Bass is secondary though.
For this purpose which family do you recommend? 6DJ8 or 6922 or something else? which make and model? approx ebay pricing?
Can you recommend me my top 5 choices?
Thank You
Aakshey

Can you recommend me my top 5 choices? Thank You Aakshey I can't understand what you are looking for from that description. It's just full of cliches that some hi fi nerd uses. How can a tube be neutral, but have forward mids, thumping bass and super clear top? Do you want strong bass? Do you want strong treble? Do you want both bass and treble to be strong? (V shaped?) Do you want forward mids so less bass and treble? Aakshey, you are talking utter tosh. Who taught you these daft terms? Get the amp first and listen to the tube in it. Who says the tube it comes with needs changing? Why are you intent on changing the tube when you haven't even heard the amp? These descriptions that you are demanding from a tube are just tosh. You are talking nonsense which is exactly why some people are not taking you seriously. This is most important - with hi fi, USE YOUR EARS. Don't start making changes until you've actually heard it!! Also, please stop with pm copies. I really don't need a copy of that tosh in my inbox! Seriously, it reads like you need therapy. I've been doing some recording today and I passed your pm around the band. At least they laughed, but they didn't think you could possibly be serious!! Relax. Listen to the amp. One change at a time - ONLY IF IT IS NECESSARY. Mods just for mods sake is an idiot's game. Also, why are you relying on everyone else to make your choices for you? Surely you have a pair of ears. Use them when it arrives! You are beginning to grate on this forum. Perhaps you should post that daft set of questions on Headfi. At least they'll answer you honestly and that would be funny. Your demands are unreasonable and none of us appreciate this incessant line of questioning on here, by pm or by email. You are being quite unreasonable demanding Jeremy to reply to 4 emails on a Sunday when he's not even working. Start to be reasonable and read what you've written. It is complete and utter tosh. How can we take you seriously. Now shape up, and start thinking properly because this is getting silly and it can't go on for much longer, I promise you.

I want a sound signature like the headphone RS 180
It is bright,
It has thumping above neutral bass
It has above neutral mids, so fwd mids.
And it has a huge sound stage.
Check the headphone.com graph for rs 180
It has all 3 things more than neutral but is A shaped. But all three are above the neutral line. Yet the sound stage is huge. Not as good as K701 but comparable to HD 558 which for a wireless headphone is a decently big soundstage.

Garage 1217 Amplifiers are all 'flat' they do not even deviate 0.5 dB over the entire audible range.
Headphones deviate +/- 10dB easily may be even more and this is what determines THEIR sound. An amplifier cannot do that unless you use tone control. And weird ones at that as the peaks and dips like that in headphones cannot be made with simple tone controls. Also the amounts of distortion in most headphones is much higher than that of amps.
The Ember you bought is one of the most flexible ones in existence when it comes so 'synergy' with headphones.
Since you are going to use it as a pre-amp this means that part (the synergy with headphones) is not in use unless you use a headphone.
I suggest you wait until the amp arrives, listen to it and then decide.
I will humour you once again...
You see there is not a single manufacturer that can sprinkle a dab of: Neutral or slightly bright treble shouldn't be warm. (This sentence contains key words that are NOT associated with tubes)
Extremely crisp, better than rca clear top Have you heard the RCA clear top and isn't it crisp enough ? The word 'clear top' is NOT related to sonics but to the fact that the top of the tube doesn't contain the deposited materials from the getter flash that is done to 'burn' the last air molecules after being vacuum-ed. That flash is on the side of the tube. The FR extension is up to 100kHz unlike the Ocean which drops off in the audible range.
Super fast attack and prat, better than rca clear top The term PRAT is a so called nonsensical term, Pace Rhythm and Timing cannot be altered by any amp, they just amplify a voltage. Why would the RCA suck or be bettered in that area by any other tube ?
Super clean, super clear and super transparent, better than rca clear top Ember sounds that way, it is not because of the tube but determined by the design.
Forward mids or very forward mids or slightly forward mids. This is not an asset amps can bring.
If possible, thumping bass as well. And if possible strong bass. Bass is secondary though. That will depend on the recording and used headphone or speaker and or settings of a tone control
Any sellers that tell you they can 'select' the features you want and put them in a single design are lying.
Relax, wait till the amp arrives, listen to it, play with the settings and if you like it drop a small post telling us you like it. If it is not what you were looking for, offer it for sale.

Dear Ian and Frans, I realise I'm slightly O/T here but I'm just looking for some advice.
I'm going to be internally re-wiring my B&W CDM7-NT speakers in the next couple of months.
I have some pure, solid silver wire, some lovely silver plated copper, and some plain (but good quality) copper cable.
My question is which of the above cables would give me : --
A really spry top end. I want brighter than XLR, but darker than RCA, maybe something like BNC would be perfect?? I always aim to be a TWAT - because I love Tinkle, Wham and Thwack.
I want my mids to be forward. Really forward. So forward in fact that they are projecting from the front of the speaker like a "mids-spike". My listening spot is approx. 8 feet away from each speaker, so the "mids-spike" couldn't project any further than that or they might actually stick into me and injure me. Maybe pure silver for these? How far does pure silver project? I have read some reports that it's 4 feet, some say it is 8 feet. I need to know!!
And now we come to bass. Wow, BASS. Bass. I love bass so much, I love just saying it!! Bass, bass, bass. The bass I want, the bass I need, must have real Wham - remember, I'm a TWAT. When Phil Collins hits those drum strikes in "In the Air Tonight", I want my down-stairs neighbour to think a small elephant has tripped over a mouse and fallen on the floor! A few times.
Now I know the most common reply to the often asked question, "How do i get 'small elephant tripping over a mouse and falling on the floor several times bass?", would be "Go for the copper cable - and the thicker the better", but I want to try to think out-of-the-box. I'm good at thinking out of my box. What do you think of silver-plated copper here? My thought process goes like this - reasonably thick copper cable - representing the elephant (doesn't have to be too thick, because as I've said the elephant is only young, maybe 2 or 3 years old, I'm not sure), and the silver plating representing the mouse. BTW, I'm not sure how old the mouse is, I don't know if that's important. Do you think it is?? I'll try to find out if you think it is. So I think silver plated copper would be best for Phil Collins to sound like an elephant, a mouse, and a TWAT.
In terms of musicality, I think I definitely want that. If I didn't have musicality I wouldn't be listening to music - and then I'd just be sitting in front of my speakers in complete silence! And that would just be silly. Who would think I was a TWAT then??
I would also like them to be as neutral and accurate as possible. I have heard that very coloured speakers aren't so good, and at the moment my B & W's have a lovely reddish rosewood veneer, but for the sake of neutrality, I 'm going to paint them a light biege, which I think is very,very neutral. Concerning accuracy, do you think 'to the third decimal point' is accurate enough? I'm thinking pure silver cable here, because I think silver is more accurate than copper, don't you?? I think it's to do with silver being quite shiny. Bet you didn't think of that!! See, I told you I was out of my box!
I have heard of some speakers sounding quite well-balanced and I think I have already achieved this. I have them sitting on concrete slabs and I have checked them thoroughly with a laser spirit level and they are definitely not wobbly or anything, so I think they are well balanced already. No chance of these TWATS falling over!!
BTW, I'm not bothered about so-called 'transparency', as I think that's a myth. Everyone knows sound is invisible so it's all transparent anyway. Who do they think they're kidding!!
Anyway , let me know what you think.
Jeff
P.S. Bass isn't actually that important.

Hi Jeff. I have to admit that really made me laugh. And I actually have the answer. Don't buy any hi fi. Buy a plane ticket to India instead. It'll do you a lot of good. When you arrive, look for this person holding a card up with your name and take his bloody speakers and you give him a decent headphone. These messages will self-destruct in about 30 minutes when Frans sees them, but I'm taking a copy into work today and adding it to the copies I posted on the wall for the other guys!!

I have some pure, solid silver wire, some lovely silver plated copper, and some plain (but good quality) copper cable. My question is which of the above cables would give me : -- A really spry top end. I want brighter than XLR, but darker than RCA, maybe something like BNC would be perfect?? I always aim to be a TWAT - because I love Tinkle, Wham and Thwack. Decide the percentage of brightness you seek and then determine the length of wire needed for the tweeter to connect to the XO. Then cut off the same percentage of solid silver wire. this MUST be soldered with silver solder to the tweeter otherwise you won't get the silver linings around your tweets. Next determine how many percentage of smoothness you want and cut that percentage of the plain copper wire which must be 3x as thick as the silver wire. Now here comes the secret trick no cable seller will tell you but they ALL do it. Solder that with 2 solder types applied at the same time, led-free solder (no mistake there I did not mean lead-free as that sucks) COMBINED with silversolder in a 50-70 percent ratio. This will give you a better connection as you will have 120% in total instead of the usual 100%. Now the remaining percentage of wire must be silver plated copper and must be twice the diameter of the pure silver wire. Now the funny part.... solder that with 'normal' solder to the copper wire (must be vintage Radio-Shack wire which is hard to get) as that smells better and those fumes give the sound a smoky atmosphere which is nice when listening to jazz recorded in a smoke filled Jazz-club. Solder that wire to the filter with aluminium solder NOT any other solder IF you have a textile dome tweeter. This will give you the idea you are listening to a softer-metal dome tweeter. Finally as cables are directional each wire has to be duplicated and paralleled to the other wire but REVERSE. This will ensure the tweeter membrane moves in both directions in the same speed and amplitude which is important to obtain TWAT. I want my mids to be forward. Really forward. So forward in fact that they are projecting from the front of the speaker like a "mids-spike". My listening spot is approx. 8 feet away from each speaker, so the "mids-spike" couldn't project any further than that or they might actually stick into me and injure me. Maybe pure silver for these? How far does pure silver project? I have read some reports that it's 4 feet, some say it is 8 feet. I need to know!! It isn't the cable IMO but opinions differ on this matter. What I do .... remove the midrange speaker (driver) from the cabinet and mount it in a PVC tube which in turn is mounted in the hole of the baffle the midrange speaker was mounted in. You need 2 pipes that fit inside each other and have a tight seal but can still slide into each other. Start with a combined tube that extends to your listening spot (8 feet so 2 tubes of 4 feet length) and start LISTENING. If it sounds to forward simply slide the tube inwards. IF you reached the minimum length of the tube and want it sound a bit less forward saw both tubes in half and listen again. Adjust to your need. b.t.w. when you slide the 2 tubes all the way out be sure to leave some overlap otherwise the smaller tube will fall out and depending on it's sheer weight may sound like an elephant or mouse dropping on the floor. 2 tubes of 4 foot do thus NOT reach the full 8 foot BUT you don't want that either otherwise the mids will 'block' the tweeter. And now we come to bass. Wow, BASS. Bass. I love bass so much, I love just saying it!! Bass, bass, bass. The bass I want, the bass I need, must have real Wham - remember, I'm a TWAT. When Phil Collins hits those drum strikes in "In the Air Tonight", I want my down-stairs neighbour to think a small elephant has tripped over a mouse and fallen on the floor! A few times. You need a SUB... and not just any SUB, no sir.... you need to visit a store where they sell professional PA systems and you need to get a BIG one, also include an amp that has the needed headroom, say 1kW. It MUST be of the same brand as the speaker used in your avatar otherwise the culture shock may be too high. Now I know the most common reply to the often asked question, "How do i get 'small elephant tripping over a mouse and falling on the floor several times bass?", would be "Go for the copper cable - and the thicker the better", but I want to try to think out-of-the-box. I'm good at thinking out of my box. What do you think of silver-plated copper here? My thought process goes like this - reasonably thick copper cable - representing the elephant (doesn't have to be too thick, because as I've said the elephant is only young, maybe 2 or 3 years old, I'm not sure), and the silver plating representing the mouse. BTW, I'm not sure how old the mouse is, I don't know if that's important. Do you think it is?? I'll try to find out if you think it is. So I think silver plated copper would be best for Phil Collins to sound like an elephant, a mouse, and a TWAT.
As I said earlier... forget about that.. just buy that sub... 2 if you have stereo. In terms of musicality, I think I definitely want that. If I didn't have musicality I wouldn't be listening to music - and then I'd just be sitting in front of my speakers in complete silence! And that would just be silly. Who would think I was a TWAT then?? We would.. I would also like them to be as neutral and accurate as possible. I have heard that very coloured speakers aren't so good, and at the moment my B & W's have a lovely reddish rosewood veneer, but for the sake of neutrality, I 'm going to paint them a light biege, which I think is very,very neutral. Concerning accuracy, do you think 'to the third decimal point' is accurate enough? I'm thinking pure silver cable here, because I think silver is more accurate than copper, don't you?? I think it's to do with silver being quite shiny. Bet you didn't think of that!! See, I told you I was out of my box! As soon as you start thinking outside the box you lost your neutrality so STOP thinking outside the box and you'll be fine I have heard of some speakers sounding quite well-balanced and I think I have already achieved this. I have them sitting on concrete slabs and I have checked them thoroughly with a laser spirit level and they are definitely not wobbly or anything, so I think they are well balanced already. No chance of these TWATS falling over!! Just put them on 3 spikes, this balances all speakers DO make sure they are level and don't hang them on walls or from ceilings as spikes won't help in that case. BTW, I'm not bothered about so-called 'transparency', as I think that's a myth. Everyone knows sound is invisible so it's all transparent anyway. Who do they think they're kidding!! How can you say that ? never seen the mythbusters episode where they play with that gas-tube-flame thingy... of course it is visible why else would they make a TV episode for it if you cannot see it... duhhh Anyway , let me know what you think. Jeff We just did... hope you are happy now. P.S. Bass isn't actually that important. Loose the sub(s)..... or remove the woofer from the cabinet and keep the sub-woofer(s) either way will be fine

These are BRILLIANT examples of the utter tosh that some people use in describing hi fi. What is amazing is the high quality responses are totally ignored and the tosh continues.
Aakshey gets my 'Meerkat' award for this complete, utter nonsense. Ie; the rope is beginning to get long enough........

Holy thread resurrection Batman! Sometimes I wish I'd never given up drugs. Just thank your lucky stars you weren't around at the time or you might well have gone back on them but with higher doses. A boss of mine used to say that every visitor brought him joy, some when they entered and some when they left (his office). Guess which category this visitor fitted in IMHO . Dave.

Aye, I hear you, lol. Head-fi is full of these people. I kinda admire their enthusiasm to be honest. It can wear you down though, no doubt.

Not for too long on here though. Something that I do find a bit tiresome on HF sometimes, is that for every statement made, someone comes in and tries to humiliate or knock you down. It's a really childish and nerdish thing to do. Failing that, they go flat out to prove you wrong!,

This isn't really on-topic but I hate it when someone says they have 300 to spend. 300 what? Macaroon bars? Arses!
