Compact amplifier/CD player w/o speakers

AKG:

Forgot about the Arcam.

Another possibility that's not too long in the tooth.

Marantz has a new CD/Receiver for $700.

If you are willing to shop used NAD made a couple that may be around $200/used.

One was the 40 and the other/later was the 715 (forget the complete model #'s and the 40 was better).

Also used/high quality, but older, would be one of the Linn Classik units (various versions all named Classik).

I've been using Sharp SD-EX111 for 15+ years for casual listening, but I rarely see them for sale anymore.

The Sharp retailed for $500 and was closed out for $75.

I purchased 5 @ that point and still have one in use and one NIB (one crapped out after many years and I gifted the other 2).

If they are still in production Denon has a mini system CD/amp combo (maybe tuner - forget) for around $500. which competed well against the Yamaha Piano Black mini system years ago.
