I got to actually look at, touch, and listen to a preproduction Ref 70 on the 14th of June. In my mind, the pictures of the Ref 70 don't do it justice. It's surprising beautiful. This unit was supposedly seven days out of the box and wasn't broken in. With that in mind, this is how a very quick, due to family issues, audition of the piece went. Within seconds of playing music, I noticed excellent separation of instruments and very nice vocals. As time went on I noticed this was very pleasing. The unit was a little edgy or a little bright, but I believe when broken in this may change. The most positive statement I can make is this. If you like the way B&K sounds, and I do, then you may find this the very best preamp they have produced. I spent less than 20 minutes with the unit, but was very impressed. My short list of possible preamps to purchase, Cary 11a, B&K Ref 70, Integra 9.8, Theta Valis, or anything below 6k with both HDMI and xlr connectivity. I have also heard the Cary 11, Classe's SSP 600, Anthem D2 (So far paired with an Ayers amp the very best non live experience I have had to date.), Anthem AVM20 which I own, and different Mac gear. The Ref 70 may have pushed the Cary and the Valis off my list. Ok, Theta really did that on it's own. All of these units are very good, but I'm hoping a broken in Ref 70 with all of it's Video abilities will prove to be just the ticket for a second HT room I'm building. No the AVM20 sin't going any where, that's my wife's system.
