Just thought I would do a post on my latest aquisition. I picked up a like new Audio Refinement Complete integrated amp with the box etc. I got from a the tech. I use for most of my audio work. He got form the family of the original owner who, sadly, passed away. It didn't come with the optional remote but I'm fixing that, more later. I think it sounds great with the Zu's, more detailed and natural than the Marantz 2252B. When set flat, the AR keeps up well with the Marantz in the low end, very close. The highs and mid detail go to the AR. I found a matching CD player on Audiogon with the remote which is the same for all their components. It is black and the amp is silver but that doesn't bother me. It doesn't have a built in phone stage so I will be on the hunt for one. Recommendations are very welcome.:yes: Anyone else have experience with Audio Refinement/YBA?
