My apologies. Admittedly I’m not a McIntosh fan.
No worries. I realize this can be like politics lol. Very much appreciate your replies. I am not wedded to Mc, just read great reviews and my own listening experiences have been good. Would definitely consider other good preamps in $4-6k used/discounted range. For a long time I had my sights set on a Classe CP800, as it not only supposedly sounded great, but its SOA USB application was outstanding and apparently was agnostic to source quality. If you have some good preamp ideas, please share!
