1. No buttons - knobs only.
2. Two knobs preferred. A maximum of three.
4. Easy to use.
I immediately thought of the Tivoli Audio Model One, but the $150 price tag kept me from getting it. Then I saw the wood-cased Sangean WR-11 for $85. Not quite as good looking as the Tivoli, but almost. Certainly attractive enough to be called pretty. No buttons: check. Three knobs: check (the third knob turns it on and selects AM or FM). Easy to use: It sure seemed like it would be. I bought it.
It arrived yesterday. The sound is rich and deep, even when the volume is turned up, and the tuning and volume knobs are pleasantly viscous when you turn them. Not much more to say about it -- my wife likes it, and so do I.
