From pass xa25 to krell k-300i

@rfprice If cash isn't a huge concern I would buy the Pass and have a shootout. Both those amps are good sellers when you make a decision. I'm a preamp fan so the dac to amp option is the X factor.

@bubba12  True, and I suppose I could even return the Pass. I hesitate because I feel like it's one of those cases of different-not-better. The Krell is a solid piece of kit. 

@rfprice I would agree. I've never heard a bad word about either amp.

My biggest piece of advice is that the Pass sound to me is unique and that a fan of that sound would not want to switch, and the OP should use their own ears rather than anyone else's when making that choice.

Personally, I'd take Luxman or Ayre over either of those, with the Ayre also having it's unique sound presentation.

I'm not familiar with the Krell but I had a Pass XA25. It wasn't for me. I prefer my Jeff Rowland Continuum S2 over the Pass. These are very different designs. I find the JRDG to be very transparent but highly musical (not analytical).
