I've bought a pair of vintage speakers that don't sound quite right with my Yamaha CR-200E vintage receiver. The sound isn't much better than what I'd expect from a pair of computer desk speakers. I'm wondering whether the poor sound quality has something to do with the speaker wattage. If so, should buy a different receiver or a different set of speakers? Photos are attached here with the device specs. I've also attached a photo of my turntable in case that helps. Many thanks. R
