Semi:
Point taken, I think that what I really should have said is musically enjoyable. Again, the associated amp and cabling can make quite a difference in the final sound.
I am using the single ended Einstein and understand that the balanced version is even better.
With respect to the Einstein preamp, it is in my opinion a real sleeper. Although it has 18 tubes, 8 of those (6922's) are not really critical to the final sound which means that no tube rolling is required for those 8. Likewise only 11 tubes are "on" at any given time, the 8 previously mentioned, a 12AU7 and two 6922's associated with the particular input to which you are listening. The two 6922's which are used as inputs for each source and the ubiquitous 12AU7 which is always on have a major impact on the sound and tube rolling is highly recommended. To me this allows a certain tailoring of the sound of each input to get the tonal mix which you desire. In general, NOS tubes sound the best, particularly the more expensive Siemens and Telefunkens fron the 1960's. Mullards of the same vintage can also be nice. The unit is sensitive to power cords, AC filtering and to mechanical isolation. The aftermarket footer sold by Acapella works well. With respect to the JC-1's and the Acapella's, what can I say that you have not already heard? The Acapella's are a more difficult load that the sensitivity would suggest, likewise the JC-1's are a much better amp than people generally give them credit for but are not perfect. I have ordered a pair of Audio Note Kegons (balanced) and think that they will be my choice for a long while but only time will tell. The combination of the Einstein phonostage and preamp are synergistic and sound very good, certainly worth an audition.
