Trying to do an accurate count here! A few have tuners that aren't working fully, but I'm counting them here as receivers.
NAD 7120 x 2. One is in my home office. One is going to my parents when I next visit
NAD 7125 - at my work office, but may be gifted to a friend
NAD 712 - also at my work office. Tuner needs the replacement bulbs, but don't really use the tuner there so not in a rush to replace it
NAD 7225 - also at work office, but headed to one of my employees over the holidays
NAD 7000 - en route right now. May set up as a pre-amp, or maybe office setup
NAD 7240 - forgot this one
NAD 7150 x 3. Two set up in Bi-amp mode with KEF Q70 speakers, one at my work office
NAD 7100 - Set up in my bedroom right now
NAD 7100X x 3 - I am thinking of using these in a biamp/biwire setup as well to see how they do as well. Sometimes switch these into second basement system and sometimes run as preamp for amps
NAD T773 - forgot this one also. Not sure it's working right now, though
So 15 right now, but at least 3 likely to be gifted away in the next few weeks
