I was going to suggest AVi Neutron, I have the fives, lovely speakers, and a very natural presentation. They sound really good on the end of a Quad 306. They crossover high up, so a lot of the artefact is out of the vocal range, and the tweeter is a gem. They’re happy working about 30cm from my walls. Very good at classical and jazz, and happy to rock out if required. I particularly like their natural timbres. That’s very important to me. A violin has to sound like a violin. No stunt bass either. They’re not a hard drive, but they did prove a bit too much for a Quad 303 when compared to a 306.
