About the synergy with low impedance headphones, my friend modified his DV332 by replacing most of its component inside with audio-grade parts, and replacing the stock IEC socket with one from Furutec.
At the end the amp sounded a lot better and to my surprise, the synergy with ATH W5K significantly improved. My friend even preferred this amp to the HA5000 (which was designed originally by ATH to use with its W5K headphones).
About the amp's operating temperature, do you guys let it run hot?
I know that vacuum tube runs hot, but what worries me about this amp is the fact that the components inside aren't so good. I don't know how much longer they can survive if the internal temperature is as high as 70-80C (I don't know if it'll be that hot but here in Thailand in summer the room temp can go as high as 33C). So I always have a big fan blown at the case to keep it cool, but the noise is so annoying.

I agree with you, the 332 isn't working at its best with low imepdance headphones, though I tried the 3322 with a pair of 32ohm SUPERLUX HD681s and it didn't sound bad at all. |
