My small experience of old with 63's (10 yrs ago) both agrees with Detlof's &, strangely, agrees & differs from Frank's above:
-The small Jadis (now Defy7) gave me great joy;
-The Jadis 80 were my "reference" at the time; note that these were wearing ancient GE tubes -- I couldn't afford to re-tube them!
-Old Symphonic Line RG4 monos (ss), were at par w/Jadis 80 in driving, but I slightly preferred the sound of J80 over the S-Line in the upper mids (maybe due to my being accustomed to tubes)
-The Quad-Linn combo's I tried were... off (surely not only a matter of components synergy but also of set-up on my part)
- EAR 519 monos: good synergy & drove the speakers well
-The A-Research I listened to (the 150, I think) didn't quite involve me emotionally.
-Finally, Quad's own 45 (?) ss, sounded harsh
Note that during that time I was using a DNM6 pre with the power amps, only had a few cd's, and listened mostly to, and judged by vinyl.
