Thanks. I've had it a couple of years. I just checked the Headroom web site for the first time in a long time and see that their desktop amps are discontinued. I'm glad I bought mine when I did, though I guess there's always the used market. I've been very satisfied with this setup.
That is almost identical to the set up I have next to my bed. Headroom desktop amp, Denon D-7000. Apple lossless files from Sonos zone player into the Headroom via toslink. I think the Headroom is an excellent amp/dac and pairs well with the Denons. I too was very disappointed to see that Headroom discontinued their desktop amps. They are kind of like a "Swiss Army Knife" of headphone amps. Very versatile.
