Oh, really? Nice! :D
Hmm, just found measurements for a lot of the basic STAX on some Russian audio site.
Is it me, or does the SR-2050 system (AKA the 202) look to have the best bass extension of the whole bunch?
I'd say these decently correlate with what I'm hearing on my Stax. Except not. Everything just sounds better on Stax than all the other gear I have!
By best are you referring to neutral bass extension or bass extension depth? 202 has hardly any bass extension depth compared to a 404/303 but is more neutral one way or another.
A good 550-600watt is all you need for Crossfire or SLi.
