I'd be curious to see what the Adcom (try to avoid the temptation to get rid of an amp like that; definitely the best incarnation of the GFA-555 series) would do powering the DQ-10s, and then drive the sub (or subs; you used both singular and plural in your latest message) with the remaining DH500. I had a DH500 powering DQ-10s for a while, and it did a good job, but I never liked the residual fan noise in my room setup. I moved to Bryston (passively cooled) and never looked back.
As for integrating a music library on NAS, it's not the least expensive option, as it does require an ongoing subscription, but I've been very happy with Roon. I use a Wiim Pro as my Roon endpoint, and my iPhone as the remote (Android devices are supported as Roon remotes as well). The Wiim Pro has an internal DAC with analog (RCA) outputs, as well as USB output, which should interface with your AV receiver, or an outboard DAC if you prefer.

Good suggestion Greg. A top-notch AV receiver like the Onkyo RZ-50 is
very capable of driving the DQ-10's on it's own, BUT, that's not
necessary because it has 2 pairs of preamp outs that can be routed to
the Hafler. So I think I'll keep two amps and one set of 10's, a sub
and the LP1 for my office/listening room. Equally important, now I can
connect a NAS, all my high def TV's etc. in one centralized unit that
will drive the surround system effortlessly too.
So if I choose to kick one off the island (as in sell) would you keep
both the Hafler DH500's and sell the Adcom (it is the MKI nelson Pass
designed early model), OR, use the Adcom for the subs and one Hafler
for the DQ-10's?
And honestly, I think I can survive with just one pair of 10's vs two
(and keep both subs??). I'm stressing the WAF already.
