So, after almost 3 years on HeadFi, I wrote my first review. Although it's on the HD800, it's as much about the synergy with the WA7. The HD800 is so dependant on the source/DAC/Amp that I truly believe that its about the HD800 and the WA7 and what it brings to me. Here's the review:
works very well and does not require separate power supply. Is basically just a filter. Curious to see how it compares to the iusb through a scope but it is pretty reasonably priced and simple. I also have a couple of the Async DACs with 3mm and optical out. sound great as well and are very reasonably priced considering they are async and have saber dac inside. would love one of these though with a highest end saber in it and the usb isolator built in.
What do you guys think of the Wa7 and the HE500 pairing? Have the WA7 on the way but that was before I heard the HE6s. Eying the 500s as my next pair of headphones so just wondering if anyone here had any wisdom to share.
Also, what does the rumored new powersupply upgrade improve on?
1) Any spare tubes to try? Strange that both would give trouble at the same time
2) Tried using it as an amp only fed by external DAC?
3) Tried using it as a DAC only feeding to an external amp? Both steps (2) & (3) will help to identify if the issue is in the DAC or amp section (somewhat but not fully).
4) Played with the switches at the back?
