Have a bose wave radio on the counter. Had it for almost 15yrs. Works fine.
It's in a big room (high ceilings)

Is there something better sound wise? It needs to be one unit (no remote speakers)CD player as well.

Tivoli?

Hard to beat a Bose for single unit music

I have a Tivoli and it is not all that great. I fact I just set it aside for a sony HD radio for the bedroom. They have not made HD radios for sometime. Tuner work way better than Tivoli. Sounds decent. You can get the Sony XDR-S3HD used on eBay.

In my livingroom I just went old school with 1960's Wharfedale W90s and Marantz reciever. Wow it sounds impressive.

for a single unit in a single room, Bose is hard to beat

Does your Bose model have audio inputs? If so, you could get an external CD player and connect that to your Wave..

Bose are nice but I am also a big fan of the Yamaha Japanese imports.

If you are down with creme color instead of black save a good amount.

I have this model (no cd to fit your needs) as my computer speakers and the sound is stunning.
