Spendor classic series might be up your alley as is the a series mentioned above. The D series probably isn't. You mentioned an interest in Quested. They are neutral and a bit dark but might not be lush enough in the mids, it really depends on the upstream gear. Never harsh though. Think tube pre and or some transformers somewhere in the signal path for maximum effect. I can easily hear changes in cables on mine but i still insist on making my own.
