Id give the nod to the liquid spark. If if went with schiit, id want the Magni+ so its DC direct. But remember the schiit amp is now discontinued, and schiit isnt known for quality or good RMA process.

This amp has known issues with left or right channel imbalance sound. Bought one a while back when it was on sale for $50. RMA first one, the second one have a stuck volume knob. It just POS.

Does this suffer from imbalance? I forget the terms, but my magni 3+ or whatever has the issue where the volume knob is sensitive to sending more audio to left or right and requires messing with it to get balanced audio.

This is a solid deal for a great "budget" amp. I use budget in quotes because it would cost a lot more money achieve an upgrade. Pair this with a inexpensive Topping or SMSL DAC and you'll have a desktop headphone setup that will sound fantastic.
