The Pass XA (class a) amps are sublime. Check out the XA 25, it puts out, as do all the Pass Class A amps, much more than the stated wattage. It is an incredible amp. Down side it is pure single ended. No balanced input. Still, just a seriously sweet amp, especially for the $$$. I think you will find, unless you need balanced inputs, the XA25 to be sweeter than the 30.8. If you want to get into the monos that opens up a Pandora’s box of greatness.
