If these amps can truly improve the bass of the SR-009 to extend as deep as the TH-900s (which I doubt), then maybe one could live with just the SR-009 setup.
Hey anakchan, I am seriously considering the sr-009, but was quickly put off by the lacking in bass from what I read around here. As I have not listen to one yet, how is the bass qty really like? Is it on par with say hd800 quantity? Or more to LCD-2 ? I hear the quality is superb, better than even the th900, just wonder about the qty.
