I'm test driving HD580 with the setup below (AV710->PIMETA), and I have to decide to keep them or not.
My main complain is that the sound is flat: a bit warm and recessed in the mids. I know that's the general complain from this model, and it's not even a fault: HD580 are ment to be uncolored, unbiased "reference" headphones...but that makes them a bit boring, even compared with $20 HD201. On the other hand, I apprecaite the soundstage, the comfort and build quality.
So I started the tweaks. I rolled amps - TI 2132, 2227, 2107;AD 823, 843, now I'm up to try 8610/20. TI chips are flat; from AD, 843 is the best chip so far, although 823 seems better in the mid/high but less detailed. I'm using 1-1-1 BUF634Ps in wide BW mode: I tried 2-1-2 with 100K res... than shorted BW 2-1-2 - not much change...but gain of 10 will rattle your toes
Now I'm a bit tired of swicthing chips, resistors etc. Could you suggest something else I can try w/o much work...different DIP-8 buffer, peculiar opamp (FET pls)... and is it really the buffers to blame?! Could anyone sell me EL2001?
Thank you very much.
