the amp looks so tempting. DY means power source in Chinese guess they may release dy-2 as upgrade version of dy 1.

So far the EF5 is very nice sounding, and a great match for the HE-5 orthodynamics, with a nice frequency response, timbre and tone. It is very musical and rich, and not dry or lifeless. It also sounds fairly well refined, like a more expensive amp.
|The EF5 has more than enough power for the HE-5, and normal listening with either amp is with the volume knob at about 10 o'clock with the EF5 in low gain. In low gain I cannot turn the volume up past 2-3 o'clock before it is louder than I can stand.|
|The EF5 soundstage is nice and big for a single ended amp, and compares well to the SAC amp which is a little more forward sounding in the mids than the EF5 but without making the EF5 sound recessed at all in the mids either. Likewise, the SAC is not close to being too forward either. The HE-5 obviously don't have as deep a soundstage as the HD800, but with the EF5 and SAC amp I think it is better than my RS-1 with flats (it was nice with the WA6 too).|
|That's all I have to report on the sound right now. I did try turning the volume down and there is still some channel imbalance introduced at very low volume levels, but below volume levels that I would listen to with full size phones.|
|But I fear this may mean still needing to use a volume attenuator when using IEM with the EF5 in low gain. I will try IEM with it later. Fortunately the EF5 does not let music leak through when the volume knob is set at Zero, like my old EF1 did.|

Er, where were we ? HPA, would you consider the EF2 (with the right tubes) to be a good amp for the HD600 ?
