Quote: I've seen this done on satellites (a little larger than headphones I agree).  Take a satellite and place it on the world's largest subwoofer and do a frequency sweep to check that the vibration modes are where they are expected.  (I say subwoofer deliberately, when I asked, I was...

Quote: Ooch.. Expat Brit in fact   (Although been here long enough that a lot of Germany has rubbed off on me).   Just listened to the pair of 'phones again, late at night so no deep analysis.  The HD-800's amaze with clarity and detail every time I listen, but it is with the D7000's...

Quote: A very good answer.   I have both.  Forced to a choice I would actually keep the D7000's - they are truly fun and engaging.  I would however prefer not to have to make the choice!   I agree that technically the HD-800s are better, but give me a late night, a glass of whisky...

Could ask for reasoning or a pointer to a reliable reference for some statements On many forum sites I often see many assertions that are neither backed up by any reasoning or can point to reliable sources - which to me is a pretty good definition of how "old wives' tales" start.........

Always worth remembering that one is comparing apples and oranges when doing direct price comparisons between direct buy from China and buying from EU or US. At the moment (and it will not last as China's economy progresses) one should expect much better 'bang for buck' buying from a well...

I can not give any positive recommendations for headphones (more below), but can point out a place to look to make a short list. HeadRoom (HeadRoom: Stereo Headphones, Amps & DACs, Wireless, Noise Canceling, Ear Canal, Earbud, Audio Cables & Accessories) publish performance graphs on their site...

I've heard this before but do not understand it. I would expect a decent amp to be either very low impedance (i.e. tending to perfect voltage source) or very high impedance (tending to perfect current source). There is apparently some standard for 120ohm o/p impedance for headphone jacks but see...

Headphones: No brand identified. Spent more than I should have on expensive phones from Sennheiser, Denon, Shure and Sony. All have their comparative strengths. Headphone amps. To some extent Little Dot. Their quality and service are superb, and I appreciate the gains that I make from...

You may want to look also at the Little Dot amps (Little-Tube) - I have bought from them myself and they are of high quality and very well priced (paying for direct import from China rather than western economy prices). Search through the forums for reviews / comments.

What about the Denon AH-D2000's. Extremely comfortable, IMHO very good and non fatiguing sound. The only issue for you may be that they are not the strongest (of closed 'phones) for isolation. Well worth a look (errr.. listen) though.

Good to see someone speaking sense here. What at first sight appears to be the standard (2 x 3 pin XLR's) being a bit of a bodge and the rather elegant 4pin XLR being in a minority. Maybe I'll start another thread for a vote on what people would prefer. As an aside (since I'm half thinking...

I would not sell the HD-800's; I've had a pair for a few weeks now and there is one thing that is very clear with them; they are revealing, both with amps and music. Amps; I've 3 amps that I've tried them with, all medium range; Little dot mk III, Little dot mk V and a Meier Corda Cantata.2...

Your problem could be that the files are lossless. As I understand, the IPOD is designed to use the HD as infrequently as possible and attempts to cache whole song(s) in RAM. With large lossless files this approach is not possible (they are too large to fit entirely in the cache) and the end...

The comparison does not quite work like that - for 1Hz I'd tend to agree with you since we are in the very low frequency range and the reactance of the driver (a mixture of inductive (from the coil) and electromagnetic (from the interaction of the coil with the electromagnetic (i.e. the magnet...

A lot of misunderstanding here. A square wave is not DC. A square wave can be decomposed down a series of sine waves; specifically one at the fundamental frequency and then an infinite series of higher frequencies (the odd harmonics (i.e 3.f, 5.f, 7.f etc) each divided by the harmonic...

I strongly doubt that a square wave will damage single driver headphones. Tweeters on speakers can be damaged by a square wave or distortion since any clipped signal contains a significant amount of high frequency component which is then routed to the tweeter by the speaker crossover...

OK, I did it; just bought a pair of HD-800s. Initial impressions; In the shop; At home; Keepers for sure. Give me some weeks to burn them in and to fully acquaint myself with them and I will report my conclusions then.

Now I am happy again, my HD-650 are in for warranty repair (more about that later), but my Denon D5000's have arrived. They are very musical and very enjoyable (been using my Senn HD-380's (competent, but a little 'dead') or my AKG-K701s (which I am am going to have to sell - I just cannot get...

Hi All, the headphones that I have tried so far and my (personal) rating of how enjoyable they are (most enjoyable 1st); Senn. HD-650 Denon D2000 Shure SE530 Senn HD-380 AKG-K701 All used amped (Little Dot Mk III, Meier Cantata. Meier Move3 - yet to make up my mind which amp I...

Hi Mopps, yep I know HiFi Profi (and believe me, they know me - enough to generally be very pleased when they see me (and for my wallet to shake)). They do go reasonably high end on some of their gear (e.g. speakers with a price tag (new car level) that I am never going to go for (especially...
