100+ Head-Fier
I have got mine yesterday... All I said it is really solid, and the sound is just amazing.. it makes my sony z1r sound like it is a difference headphone comparing when i use it with WA6SE before. But the one bothering me is, the amp is not dead silence, at least mine. When i hooked up my Z1R i and stop down the volume lever till zero, i can hear a noise, maybe not a noise but something like the sound of the working valve.. It is like the sound coming from the inside of the valve..
Yesterday, I use my HE1000 and the amp is dead silence...
The Sony's are far more efficient (sensitive) than the HE-1000's, so it's not surprising you would hear tube rush through them that you don't hear from the HE-1000's. There really is no low-power substitute for the 2A3's used in the WA33, but there might be a low-output setting beyond the volume control that helps or impedance-matching settings like the WA5-LE has that could minimize the tube rush that you hear through the Sony's.
