Apos

Got a bad S.M.S.L. unit first, but Apos gave me a return credit, and I went with a Topping E70V that I'm very happy with.

Nice peace of kit. I have been getting a steady diet of 48 kHz PCM into my DAC. I use the coax input into the DAC. ROON does not recognize the DAC. I have to use system output from ROON

Easy to deal with. Quick to respond to any questions. Free shipping. What's not to like.

Shipping was a ok

I've used Apos before for a number of things, I didn't price match this time but I have before. They have generally great prices and fast shipping. Not sure about returns as I've never done them before, but unless you return quickly it's a 20% processing fee. I'm not sure how the warranty service works either as I haven't used it, but I might in the future, if that works really well I guess I might bump it up to 5.
