To use the Ruark talisman and MS on the Denon DHT390 will be so under performing.
Shouldn't be a problem connecting those speakers. A proper and more powerful AV amp will be a better match for such fine speakers. A waste in my opinion, to use with the Denon htib.

vsx-d902s is just an old pro logic amp, if its just a minor repair its ok. Can use as spare amp, but if its major, might as well change to the new generation ac3/dts amps...
