The best integrated a I have heard so far:
KR Audio VA680 and SXi
Ayon Crossfire III
NAT symbiosis SE (but only after at least 2 hours of continuous playing)
Ypsilon Phaeton
KR Audio VA350i
Soon I will be demoing the Aries Cerat Diana ( I have it now but must get the beast in place). Will it crush the rest?? Time will tell...
Is the VA680 still under production?
