Over the past 30 years I have owned three ARC amps:
D76A, D115 MKII, VT100 MKII (which I am still enjoying). They were all very musical and great performers. None could be characterized as "DRY" sounding.
Apparently Audiofeil is limited in his exposure to the ARC product line. ARC has made some of the great tube amps over the years. His ignorance speaks for itself.
