@bigtwin, jjss49:
Thanks for your comments!
I found an open box unit I hope to purchase today.
My Aqua La Voce II DAC was $2700 when new, for whatever that's worth.
Lately, I've been experiencing a dissatisfaction with the overtly warm sonics of my system. It could be that aging-related hearing loss is to blame.
It remains to be seen whether a "very clean" DAC will appeal to me but I'm hoping the smooth but more transparent SQ of the amplifier will prove to be a welcome change.
