Love my new adcom amp I have noticed a very big change in sound quality imaging and separation of instruments and vocals is much more noticeable . The dynamics are much more focused and clear . thank you Adcom .

Preamp seems to function well, as expected. Delivery took longer than hoped for; more than a week. Other sources, like Crutchfield, deliver in two days at no extra cost. Nevertheless, the package and contents arrived in good shape. Quality of sound is good so far, but not fully tested yet.

The product arrived fairly quickly and was packaged very well. It is solidly built and well designed with plenty of inputs.
