Hey recluse,
My reference SS amps, until the XA-25, were the XA-60.8 mono blocks. So, for all intent and proposes they would sound the same as the XA-30.8. The XA-25 does not sound like a series .8 amplifier for the details either read my review on hometheaterreview.com or Six Moons excellent review of the XA-25 directly compared to the XA-30.8 amplifier.
