You know, I'm even beginning to think BenF works for Takstar. He just seems so desperate to prove how good the Pro82 is. I have one on the way now so he must have done a good job. Apparently, we're audiophiles which is why we don't like them. Even the fact that we don't like them is incorrect as well. That bloke is consistently wrong in what he writes. Smacks of desperation to me. I'm quite interested how this compares with my Sony MDR1a and MSR7 actually.

To my mind the MDR1A and MSR7 make for a good comparison as all are designed with a degree of portability in mind. Not heard the MSR7 but the P82 is definitely a better balanced headphone than the MDR-1A for sure. Bass is a lot more controlled and 'conventional'. Can understand some preferring the P82 to certain (quite polarising) TOTL headphones. The tuning and tonality is fairly agreeable and likely much less troublesome for some ears. But there are plenty of other headphones you could say that about. Where did you end up ordering from Ian? Gotta be in it to win it

An Ebay seller - Mesllisocy I think it is. Based in China but goods in Middlesex. I think just a UK distributor of the place you mentioned. Because of the Chinese New Year, nothing is happening over there whereas this one might get here in a week.
I was curious about the bass in comparison to the mdr1a. Without a Kameleon, the Sony has a real 'colouring' in its sound. The Kameleon really lifts the cloud. So I'm quite interested in how opening the ports compares as far as bass goes.
I do prefer the AT MSR7 sound though. Can be a bit brash but I think I must have acclimatised to it over time. To me, the bass is good although very much under control so I'm kind of hoping that the Takstar sits between the Sony and AT in terms of tonality.
That would probably suit me.

Just hope you don't get a fake one I agree a comp with the MSR7 and MDR1 would be in order, after all they sort of look the same. Another comp I'd be interested in would be with the COP (that is the Beyer model with the same-ish bass adjustments?)

Now that would get them going wouldn't it? I think this place is just a UK outlet and they get them from the Chinese place that Mark mentioned.
I sent them a question about the case and got a reply from China saying that they're closed for the Chinese New Year but that would make no difference if I ordered from the UK outlet. So I think they're in cohoots with 'Tomtop' or whatever they call themselves.
I just don't want an older version. Whether it's fake or real......

I saw that Mark. I reckon it is China based. I've been given a faster arrival date I think though.
The listing says Middlesex but the email to my question came from China. Not sure whether he's a separate seller or part of the same place.
Oh well. As long as it's not a fake .....

Tomtop seem to be a decent enough seller (or supplier) so think you're in good hands Ian.

Gotta watch that whole "origin" thing on ebay. I was looking at a Topping d30 which was specifically listed as being from a US seller. Further investigation (looking at feedback) and I found it'll probably be shipped from China anyways. Even if I did luck out and get it from the US any issues would need to be dealt through China anyways (apparently happened to at least one buyer)
I have read about a couple people that have had issues with Tomtop - mostly delayed shipping IIRC. Overall though they seem to have a better rep than most random AE sellers. Really, my biggest worry would be getting the most recent revision

It looks as though I'm ok. I've just had an email saying that the headphone has been dispatched and I only ordered it yesterday. So I think they do take the orders in the UK but the headphone is possibly coming from China. It's still a holiday over there so I'm not sure how it got dispatched!!

After repairing the L-R imbalance of the black PRO82 I seem to have accidentally overloaded one channel when I did some squarewave measurements again. This is always on one channel and have to turn the volume knob back a bit. As this is a closed headphone you can't hear it playing loud, certainly not at 40Hz squarewaves. Turns out the driver had about 80mW (1.6V) of continuous signal on it. As the driver is rated at 50mW max. (and 20mW cont.) that driver burnt out. Most drivers are rated at 100mW to 200mW and have never burnt out a driver so far. Anyway... I searched around in a box with drivers I rescued out of headphones over the years and found a nice looking 40mm driver. Transplanted those drivers in the PRO82 housing and was surprised to find it measured almost exactly the same as the black driver except with elevated treble well above that of the silver version. The driver transplant and a small peak filter gave me results quite similar to the now departed black PRO82 driver. Treble extension is even better and 'finer details' as well. Just slightly less bassy sounding. The CSD also improved and there are less resonances and lingering which is also seen in the spectrum plot. The impulse response is almost the same, just showing slightly less sub-bass response. Below the L and R frequency response of the PRO82 with the other (alas unknown from which headphone) + hardware filter. Now ... nobody tell Mark I destroyed his beloved PRO-82 otherwise my supply of headphones being sent my way for measurements may run dry.

Awesome. Now you can start selling them through G1217 and really make that Head-Fi guy's head explode (you wouldn't happen to have a pair of 53mm drivers kicking round your magic box of parts? still wouldn't mind getting my hp150 resurrected )

Did someone mention drivers? I know Frans isn't exactly a fan but he's taking this "fuelled by hate" thing a bit too far, isn't he? Accidentally overloaded one channel....hmmmm.

Actually, for a pro headphone that in itself makes it a no go. Most pro headphones take a lot of power and have solid thick wiring and coils so they can be used as mini speakers. They're rated very low in that respect. Knowing my luck, when mine arrives, I'll plug it into an Ipod and it'll fizzle out then ........ The mobile phone might well turn it into a heater ...... Quite funny that you've gone and blown it up though Frans.

Accidentally overloaded one channel....hmmmm. Yes, the amplifier I am showing above was perhaps a bit too much for that poor 20mW driver. It was a good thing I was wearing goggles at that moment as well. For the picture I took of my penguin suite. It was highly synergystic and the best sounding/performing amp I had at that moment. couldn't have wished for more synergy goodness.
