Over the years, I'd put the Marantz 8B at the top of my list for doing everything well. Tight bass, nice mids and hghs. I just bitterly regret I sold it. My actual Quad II are really great.. sweet. Not for everybody. I built an SE300B.. extraordinary mids and highs.. a bit slow on bass.. my 45 tube se does better, even in bass.
Tubes are fun!
