I am a current owner and I use the built in phono stage exclusively. To my ears it is very neural and authentic in sound reproduction. I have rolled all my 12AX7 and 12AU7 tubes. I was fortunate to get KT120s a few years back when you could still get them on ebay. I did hear that the KT88s sound warmer (more tube-like) with a minimal drop in overall output. I visited the factory this year to get my II upgraded to the III (non dark). I learned that they find the Magnepan speakers their choice for demoing the amp. I auditioned used mags and found that pair not worth it, not to mention my room cannot really accommodate that speaker size.
Unless something radical changes, this is my "life" amp I got the HT option and processor loop added so I ca use a tube preamp for my digital side and add an eq as my hearing needs evolve.
My vote is a positive. the ultra-linear/triod switch was a big deal for me. I did find rolling the 12A tubes really brought out better sound. The factory tubes are fine, but there are better sounding tubes out there.
As far as my listening goes I enjoy progressive rock and when solo artists explore a hybrid classical/rock sound plus some classical, mostly piano. I strongly prefer vinyl, and stream when I want to explore music I don't own.
