Been away from this thread for a while now. Just got this hooked up to a pair of LS50's, and it sounds great -- no surprise at all why it's an oft-mentioned combination. Even non-audiophiles have commented on the quality.
I have run into an issue however. When playing music from Spotify, the songs will pause or skip from time to time (usually around the beginning or towards the end of each track). It is hugely annoying, and doesn't happen when using the built-in speakers on my iMac w/Spotify. Nor does it ever happen with iTunes. I haven't tried testing if the same thing happens with other DAC/amp combos, but has anyone else run into similar issues?
I'm inclined to think it's a Spotify issue, but who knows...
I sometimes run Spotify and Tidal with usb from my MacBook Pro to the MHA100. I currently run Tidal and Sirius XM through a Sonos player through the optical. I've had no issues with either. I do have Radium for Mac and it pauses/skips directly on my MacBook though.
