Amps.. Is Odyssey worth it?

Driving a B&W 802 F ?

Odyssey amps are a bargain for their price, especially used.

I’ve had both, a tricked out Khartago and a Stratos which I added (4) 22,000 uF caps. The Stratos is a direct copy of a higher end German Symphonic Line amplifier. Very well made. 

Your speakers are at 91db?

Either amp should easily drive them. Personally, I'd go with the Stratos. I'm a proponent of more power is better, and it's built to a higher standard than the Khartago.

No. I had a Stratos amp, a Tempest preamp and a Candela preamp. Two of them developed either a hum or spurious noise. I could not get them fixed correctly by the owner. After two years of back and forth shipping to Odyssey Klaus eventually bought them back at a big loss to me. He stated I had bad AC in my home. Never again. By the way, he lended me a Symphonic Line integrated while I waited for my equipment. It worked beautifully and it was very used.

Your first time posting here??? Interesting.
