Lightning quick DYNAMIC amp in the under $1000 range

So the STA-200 vs. Schiit Vidar is an interesting comparison. What would be the pros and cons of each be? The Vidar seems like it could have the edge with more power and overhead by being able to deliver twice the power when you go down to 4 ohm. Does the the STA-200 do this? There is no 4 ohm measurement that I saw on the AA website. Anyone out there that have tried both? What did you prefer?

Not surprising for a class D amp.

kosst, I think it’s linear, but still just looking under it’s skirt, the Vidar gets my nod by a long way.

Not always true. The Hypex NC400 is stable down to 1ohm. The ICE ASC300 (PS Audio & Emotiva) is stable down to 2.5ohm.

 These are older, but they are great values:

Aragon 2004

 I admire both of these amps. Anyone else have experience with them?
