Rich,
I guess I will find out myself, when I found out the RR2150
had a USB input I decided to buy one and expect it later
this week. I will give my two cents vs the NAD (which btw is
a 325 not a 326, I forgot what I owned). Between the phono,
the tuner and the USB the Outlaw is a nice little package
(also the option to use a better power cord is a big plus)
and if it's sound (sensitivity) is a bit better than the NAD
like you mention above, a steal at $499 used.
best
Phil
