Thank you Franz. I guess when I looked my visual discrimination wasn't good enough to spot it. The "Thermionic Valve" verbage camouflaged it I expect.

Jan Philips 6922 are nice middle of the road tube and can be had for low money Simon. Always liked them in the X-Cans. I may also try to get one of the ones that Jeremy likes as well just out of curiosity, but if the cost starts creeping, I start to think about a new headphone instead!! i think i have reached the peak as far as headphones are concerned, especially since adding the filter. though i am curious on the t50rp with filter. if this proved to be close in performance to my lcd2/filter then the lcd2 would be on ebay. i doubt i will ever find out. also if i do start using a portable device again, as in the fiio x3, i will then need some closed back headphones for that. i only tend to use portables in the garden during the summer, so there is no rush for this now. |

I'm waiting for Frans to develop the CMoy that has the power and filter for the `t50!! I would definitely be using the `t50 mobile then.

Further playing around with the Ember and output settings today with the K601 which I do like basically because it's kind of 'unremarkable' sounding. Ie; no big bass humps with nothing glaring. IMO, that's its real strength.
This headphone resembles the K701 but doesn't quite have that hard steel edge of the 701 or 702. Anyway, set the output impedance on the Ember to 100 ohms and this headphone turns into a more mellow beast altogether. In fact, it's actually very clean sounding and crystal with a warm treble....... Yes, a warm treble.
For me, if the treble isn't rightish, I can't easily live with the headphone. Again, it's a 'timbre' thing. Some headphones can sound very 'steely' in the treble while others sound 'mushy'. I like a healthy top but not a hard edge. Some think that the 'hard edge' type of sound is 'detail' but it's really not. It could be that headphones show a big peak up in the top which reveals itself as this 'edge' that I hate. Other headphones can go too far the other way, with a too smooth, curtailed treble, but I find that easier to live with than that cold edge that some produce.
The k601 top is about right for me on 100 ohms. It's also remarkably open sounding and a new term ...... 'hear-through'. Not clouded up with mid bass or a kind of 'smog' within the sound. On good recordings, it's great in the bass. On masters, the bass is stunning.
I still feel that the k601 is underrated and sells very cheap for what you get. The Ember really makes it sing.
The configuration of the Ember is such a genius idea. Frans ..... a configurable Cmoy? Is it possible? Preferably with a fat lithium ion battery?
The ultimate for me would be a configurable portable with lots of output power!!! I'm writing to Santa about it now.
Seriously, the k601 is exceptional so now I wish I'd kept the 701 in order to try it with the Ember. I may look for a cheap 702. I hate paying for headphones!!!
It's either a configurable Cmoy or a suitcase from Jeremy so I can pack the Ember up for flights and suitcases.

Definitely look for a cheap k702 - high gain, high output resistance and input caps on sounds great and pretty mellow. Harsher than my 650s of course but not by as much as you'd expect |

I really didn't like the K701 treble. I could hear 'ringing' and it turns out that in fact it is a bit of a 'ringer' around 10kHz. It's possible the K702 is the same. However the 100 ohms output on the Ember creates a rather nice top end in spite of the peaks on the headphones.

The K550 does the same thing.
Frans, do you think that all AKG's are working to 120 out as a standard? It's not just the timbre in the treble that I think is affected, but the bass is raised slightly as well. It's as though the fr has been tilted back the other way a tiny bit, which makes them sound easier on the ears.
Or whether the treble response comes down a fraction so you turn up the volume slightly instinctively, give the bass a chance to develop more at the slightly higher volume?
It's not a massive change, but noticeable so that they just sound less shrill. Or my head is playing tricks again.

No Simon. I don't think so. Frans started it by mentioning an on-board t40 filter. (With a switch off Frans)  Even better, an integrated coffee perculator.  |

Perhaps it would be a fun 'project' for the winter.
It would have a single 9V battery (or perhaps 2) and think I would do 3.5mm input and output on the front panel and no volume control.
Perhaps 3.5mm in and 6.3mm out (I have my own amp made this way)
Still only in 'mental' phase asking myself if this would be a fun thing to do.
Would have to be low current consumption and deliver enough power.
Have some ideas but takes a lot of testing e.t.c.

What, no volume and no coffee maker?  No volume = no iPods from dock connector. |

I know its on here somewhere, but does anyone know Jeremy`s website link, i feel an Ember coming on!! Thanks. Mick. look forward to reading how you compare it to the EF-5, if you still have it. i was interested in this before going for the Ember. |

There was another guy who had both and had told me the comparison. Was present in my headfi.org messages but am banned till 1st Nov. So sorry.
Anyway, the summary was that he found them in a comparable league. I don't remember everything he said but do remember that they were in the same ballpark. And the guy with the Lyr and Ember also considered them in the same league with the Burson HA-160 with Ember being his choice amongst the three.
