I find it strange that before I'd gotten the HD700, started out with a HD800 first actually, I'd gathered through various reviews and threads that the HD700 would be problematic due to treble spikes. But seriously, it sounds very warm to me, not in the least bit bright or agressive. I'm wondering if my hearing's shot to hell.....but then, I put on my HD800 and all the treble, not bright at all, is there so I'm really confused here. One thing about the HD700, I enjoy actually listening to songs with it as opposed to my HD800 which I tend to.....well, listen to the sound rather than the music. Anyway, still getting to know my cans......and tubes.
Trying out a Telefunken ECC88 6DJ8 (also have a pair of Amperex, trying to get some Mullard), I can't decide if I'm imagining it, but I did notice a little coarseness in the voice of a rather well known Chinese singer here (Jie Tou by Ah Mei) playing DSD64 tracks via my computer using Fostex music player with a Fostex HPA4 + Lyr stack. There was a little edginess/harshness when I was using the stock tubes that came with the Lyr. But with the Telefunken tubes, I noticed that this edginess seemed to have been smoothened out somewhat.....can different tubes do that?
