The only thing I would trade my X600.1 for is a Xenon Onyx 600.1 and I mean that. The X600.1 is a great amp. I have a 100.2 Onyx and that is one nice looking amp. Hifonics does not even come close to Phoenix Gold in SQ to me. Not looking to fight about it but PG make some of the best sounding amps out period.
