@Genkides, you should try the PASS amp then. XA-30.5 can grip the woofers of Focal 1037BE speakers like no other. I did have lean bass syndrome with earlier X series. XA-.5 series in a completely different league. I haven't heard Spectron amps however.
Spectron musician VS. Pass Labs Amp
Did anyone compare?
