I have no problem with Class D switch amp when pairing it with some tube pre amp.I like the 8.86 lbs due to the limited weight of my floor upstairs,
 
No serious review except a negative one from WhatHifi. Serious complaint from the end user is the annoying "whizzy" noise in stand by mode and harsh HF.
 
I am not a fan of MF house sound but the deal is so good $499.00 a pop. Please feel free to void your experience if you own one or two of these units.. Thank you.
