I did buy it, but don’t have any measurments.
Paired it with JBL Classic 100. My other system is Vinnie Rossi LIO with Harbeth P3s so really two different systems.
All in all, I like it. It seems much better than Rotel A-14 I was using with JBLs before.
I have Volume Attenuator (-20dB) set to On and never go over 60 (out of 100). Tone control is also nice feature, but I only use it for Bass.
I don’t like that VU meters are off when the display is off. Also, there’s a bug or wrong implementation of USB. If one moves from PC input to something else, it drops 5V as if you unplugged the cable so PC (HQPlaye) doesn’t know what to do. I have to restart the PC for it to start working again. They should have kept 5V on all the time. I wrote a mail to technical support two weeks ago, but not a word back,
LAPC also seams to work well (at least to my ears).
The sound (not sure how muchnof it is due to speakers), bass is great, midrange nice, highs not harsh.
What speakers you plan on pairing it with? I was actually in market for used Harbeth 40.2, but my wife’s sound of reason weighted in.
