Been sitting here, listening to my brand new, squeaky clean Sennheiser HD 650's while reading Ryan's review of them. I have to say that initially, I thought there was quite a bit of exaggeration in Ryan's opinion of just how good these things are - I was wrong, they really are that good and then some.
I've been playing my favourite tracks for a couple of hours and I'm still hearing things that I've never noticed before, not even with the AKG K702's, it's like a whole new world of micro-detail has opened up. I was a bit concerned before I got them about the sound stage and the "veil" due to rolled off high frequencies. Both of those concerns went out the window within seconds of hitting play. I don't find the sound stage to be that much smaller than the modded K702's I've been using up until now and the high frequencies seem perfect to me, detailed without excess sizzle. As for the other end, nice powerful bass without it sounding "boomy" and the legendary mid range is just right off the scale. The only negative was the initial clamping pressure but even that doesn't seem to be a problem now, whether it's eased off or I've become used to it, who knows or cares.
I think this may be the end of the line because I may well have found my perfect headphone
The Aune T1 DAC/Amp is doing a pretty decent job with these, it doesn't sound lacking in any area, bass is crisp and highs are clear plus there is plenty of volume. I may well save my pennies for a better amp in the future and feed it with the DAC part of the T1.
So thank you Ryan for the effort you put into writing your reviews, specially useful in my case as two of them were headphones I was looking at. I think what finally did it was that you sold your HD 650's in favour of the AKG's and ended up buying a new pair just a few weeks later because you missed them. As for me, I'll be selling a kidney before I'd part with these babies.
ps. It's taken me ages to write this because I keep stopping, shutting my eyes and listening to the music - currently playing Life's been good by Joe Walsh (OMG those drums!).
