Well here I sit with my brand new out of the box 750s on my head. I explained the situation to the salesperson I work with and a replacement was not problem. So I went from fully burned in 750s,to fully burned in ones (300 hrs) that were sounding so very sweet, to fried ones, and now back to fresh out of the box.
So here are my impressions. I still like them straight out of the box. This set had less clamping and the earpads don't seem as hard and constrictive as the first new pair. So there are some obvious tolerance differences in manufacture. Most noticibly is I am back to very pronounced bass--maybe ever so slightly boomy on some cuts, especially vinyl compared the the fully broken pair. But if this bass is occassionally slightly boomy (and it just may be fuller and deeper) if is not objectionable to me, kinda fun. And the bass isn't as integrated with the rest of the music. For bassheads, if you could somehow keep your HP from burning in you might retain their heavy bass.
And I am not aware of the level of sound integration and that ever so subtle and delightful quality of the sounds moving through a very fine liquid as was so apparent with the fully burned in 750s. And because of the lessened integration , the sounds do seem to emerge suddenly and a bit startingly.
Now that I think about this presentation against the burned ones, this sound is more forward than burned in ones. Another way of describing that startingly quality is that it is as if the sounds suddenly emerge out of a black background into a smaller (both wide and deep) soundstage. This is a little hard to describe, but since I so recently had fully burned in ones to compare this sound to, I can see that when the soundstage opened up in depth it allowed the sound to emerge from a greater distance (hense the sense of being able to see the sound coming) rather than to suddenly emerge out of the black background as with the new ones. I suppose what I am describing is the presence of a wider, deeper , and more integrated soundstage that happens with burn in.
What is cool for me as I attempt to objectify my subjective world is that I can see that I had it pretty accurate to my experience, at least in what I noted for the stages of brand new vs burned in 750s. At first I was pretty bummed that after so deligently burning in the 750s for so long, I lost it all. But now I can see that this served a purpose in terms of my own education in sound descrimination. I've been able to step back in time so to speak and re-examine an earlier experience. I just had to give the experience a chance to work for me.
And for anyone new reading this, on Audio Asylum I did a post of my experience doing an A/B comparison on two quality turntables yesterday. The dealer was great and set up the two turntables with the same cartridge, sound level matched the TTs and put them throught the same signal chain. (Brooks Berdan in Monrovia, CA--great experience.) Both tables were very good yet with subtle but noticable differences.
The analogy I used was that it was like comparing difference shades of white (or black to black). These colors are very close, but side by side it is easy to spot the difference. For me that is how these SQ differences are between new vs burned in 750s. So if someone is looking for dramatically big changes (like it is somehow going to be a different HP) then you'll be disappointed and maybe miss noting the real but subtle refinements that occur as burn in progresses.
Back to the music, I am missing that subtle refined liquid but I sure am enjoying this full, deep bass. As I said in an earlier post, I really, really like Ultrasones.
