Stereophile Class A

For a $1000 best to get a used integrated amp. You may be able to find a YBA Integre for about $1K. Maybe a Creek 5350. The 5350SE might be more since it is a new model, but the 5350R will be around $1K. Also look for a Classe CAP-100.

Do not forsake the Class B list. There is some very nice stuff there and some for a lot less than $1K. Bryston B60; Musical Fidelity A220 or A2; Linn Majik and many others.

For Cambridge Audio look for the discontinued A3i. It is superior to their current A500 and other offerings. The A3i was designed top to bottom by Michael Creek, so it's like getting a Creek at a big discount ($250 used). The A3i also comes with a decent moving magnet phono stage.

I use an A3i in a small system in my den/home office along with a pair of the original B&W CDM-1 speakers with MIT-T2 biwire cables; and a Stan Warren modified DVD player. Plus an Onkyo Integra Tuner and vintage Dual turntable.
