I have the Devore SIlverbacks for a few years now and I use Shindo mono blocks that are 70 watt mono amps. The speakers are really musical and detailed with great efficiency. They are very well made and are fairly easy to set up. If there is any negatives I would say they are a bit lean in the midrange .I do recommend them highly and with your class A amps they would sound great I believe . I know there is a pair for sale here that seems to be good value since they are 17 k speaker now .Good luck with your choice , sorry I couldn't give you any feedback about the Egglestones.
