Holy, listening to some Tiesto right now and the bass I'm hearing right now is great
I'm able to turn up the volume on the WA7 more than I was able to before. Anything after 9 o clock was fatiguing before. Now I can get it to about 10 o clock or a little past that and the bass is just thumping! Awesome lol.
Anyone running their WA7 on a surge protector should try running straight to the wall and see if you notice a difference as well.
It is a passive isolator with power filtering so not quite the same as the iUSB but it does not need separate power and is a lot cheaper and sounds great. I would love to see some electrical performance specs comparing the two but for the price and convenience and compactness it is definitely worth it.
They sell a Async Sabre DAC too with also includes a USB->optical converter which I have a couple of is also very nice. Great sound from the DAC. I use one at work for the DAC to drive the WA7 and the other at home for the optical to drive my HeadRoom Ultra Amp.
