    may be suitable technically (on a paper) but there would be no bass. been there, done that. he needs an active preamp with <100ohm output impedance or a passive (like TVC) that translates a source's output impedance to the actives (and in that case he needs low imp sources).

    there is absolutely no reason why a tube preamp would not be able to drive these speakers except that generally tube preamps have a higher OTP impedance than solid state, however there are exceptions like EAR for example, 864, 868, 912 etc.

    It's one of those forum cyclicle things that keep coming around I guess... some like passive and some like active.. IMO it would work fine with a passive. I have both here and I don't get "no bass" or in fact any problem with bass when using a passive... in fact a passive is flat to DC!
