Bang & Olufsen amp replacement

[SeattleBoston]

Hi there,

I'm finding very little info out there about this: my B&O amp has gone bad. No treble coming from the system. Car Toys says replace with a standard 6-channel amp, but then i lose the groovy middle speakers if I do that.

Has anyone else found a reasonable replacement for the stock B&O amp, and/or is there a good place to get the replacement OEM amp?

thanks for your help!

I see a used one on ebay for 1099
