Tung-Sol Round Plates, VT-231 or 6SN7 - Clean, fast, the best in everything, wide bandwidth, great resolution. If you can’t find the Music, it’s not the tube’s fault.
RCA VT-231, black plates, rich harmonic structure, beautiful timbre and voicing, wide soundstage
6SN7W or WGT Sylvania black plates – Tied for second and came in first if your system sounds a little laid back, especially some single ended amplifiers – Excellent low level detail resolution, very immediate sounding with a lot of Slam. There are three types of these tubes, two large bottle types, one has a metal ring and one smaller bottle with smaller plate structure. The smaller one has better low level detail and the larger ones have more slam.
Raytheon VT-231, black flat plates - like the Tungsol a little sweeter, nice balance of detail and timbre
Ken-Rad VT-231, flat black plates - Great Bass, drive, sweet midrange, good bandwidth althought micrphonic tendencies on preamps.
Sylvania VT-231, black plates, wide bandwidth, well balanced, excellent sound stage and air.
Sylvania 1952 JAN-CHS-6SN7GT bottom getter: construction identical to the earlier VT231 but sonics are not, exceeds the VT231 in every respect, real bad boys excell in every area, big tight bass, warm detailed mids, extended smooth highs, very open
National Union VT-231 - good drive and great midrange, softer bass and a touch euphonic
Tung-Sol 6SN7WGT, Black Plate, brown base – Sounds similar to the Tung-Sol VT-231, not as clean
Tung-Sol 6SN7WGT, Black Plate, brown base – Very good bandwidth, bass, detail and soundstage,
CBS/HYTRON 6SN7GT, Black Plate, quiet and musical, the best of the non-military tubes
Ken-Rad6SN7GT, black base, bass a little tubby, but clean with great ambiance and air
Sylvania Green Label 6SN7GT, first top getter on the list, non-fatiguing, smooth, with good detail resolution and bandwidth, plus its easy to find and afford.
RCA Black Plate 6SN7GT, still a side getter, rich harmonic structure and maybe a little too sweet.
Sylvania Green Label 6SN7GTB, rich harmonic structure, good midrange, decent soundstage
General Electric Black Plate 6SN7GTA, the great driver tube? Fast, wide bandwidth, smooth sound at the expense of the of low level detail. Along with the Sylvania 6SN7GTB, a great “fourth” tube in Atma-Sphere amps.
Sylvania Green Label 6SN7WGT, Top Getter, “silver top” , very clean with great detail resolution and speed. Bass can be a little tubby and midrange a little congested.
6SN7WGTA, Sylvania black base green label, clean and fast with great drive, good bass
CBS-Hytron 5692, fast, good dynamics, lot of air and great timbre
RCA Red Base 5692, very warm sweet sound, great on voices and jazz
RCA 6SN7GTB, rich midrange, warm sound, likes being combined with other 6SN7 types, likes the Atma-Spheres
G.E 6SN7GTB, Gray plates, work horse, lacks refinement, a good tube

V_D i guess only you can validate or dispute the above reviews.

If in doubt, consult the Tonomen - they have one of the largest collection of 6SN7 varieties
