Lightning quick DYNAMIC amp in the under $1000 range

@georgehifi @bstatmeister

Slew rate has nothing to do with dynamics, all it relates to is frequency range and wattage (well, voltage). If two amps have the same max wattage and frequency range, their slew rates are 100% identical.

So what determines good dynamics? Is there any spec or part or mfg process that can reliably tell us this? Or you just have to listen?

So what determines good dynamics?

A fast stable amp (extended FR) , good current ability, decent stiff power supply, that’s under control with low output impedance (good damping factor).

EG: an amp that can "double" its wattage for each halving of impedance. Increase it’s wattage by at least 70-80% from the "true, not understated" 8ohm wattage, say EG: 100w to 4ohm, 180w to 2ohm, 324w to 4ohm.

And the Vidar’s advertised spec, the Schiit can do 8ohm-100w 4ohm-200w and 2ohm-400w (2ohm only one channel at a time driven.)
This means it can do good current. (But I suspect the 8ohm wattage is understated to make the 4 look like it’s doubling)

But still these are very good figures for an amp that’s just $699!!!!, with a return if you don’t like it.
It’s dc coupled with servo and extends out to 500khz -3db!!!!!!!!

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?
