Pass Labs X1 or Krell Phantom II

I sold all my expensive hifi in 2005 and then i had a a few years with very budget friendly units. But as i recall, cast was better all through. I had a few cast cables and transparents versions was the best. I can only say, from what i heard, i would say this, go cast and don't overthink that choice. You will only end up trying to find a cable (if you go xlr) that will be close to cast. Those amps, FPB 700cx and KCT was really great. I had a speaker manufacturer in my home delivering a set of speakers. He had top of the line Electrocompanet. Among the first thing he told me was, Krell was way better. I think you will find cast cables holds it's value when you go for a Krell amp combo. 

I would  go with Pass as its a better sounding unit.Good luck.

Normal dac -> xlr -> KCT -> cast -> FPB-400cx.

Would these setup ruined the sound quality, or I have to get a Krell dac/processor with CAST too?

Ymlee,

I use an Ayre dac with xlr into evolution 707 >> krell 403E.  It sounds pretty good to my ears.  I have not tried a krell source device with cast output.
