So the KT88/90's are a good balanced tube, which oust the EL34. I'll have to ck to see if the amp has the ability to take different tubes. But that may not be the solution. Obviously the amp will still have a certain "flavor" no matter which tube. So the better thing would be to A/B the EL amp with the FU amp. Which I do not have access to.. My friend had a single ended 300B with the Silverline 4 way speaker/db93,high sensitivity. I just found classical orchestra to lack some depth, and that might be from the lack of the octaves in the lower bass region. But the sound on jazz was superclean, except the male voice has a slight bark/wooden sound in certain octaves. The Jadis Orch/Ref is a good amp, I'm just ready to move on to another bigger amp.(the other amp/Cayin EL @ $1400, Cayin FU @ ,guessing ....ah could be out my price range). So the EL is about the same/less than the $2100 Jadis/new. BTW, I can't read specs, nor the elemental tech stuff, kindly posted from Greg. The speakers I plan to get are the Seas Thor/4 ohm speaker. The Cabasse MTM's are much higher efficiency, but I must have the Seas' tweeter in my system, so the amp has to be chosen around the speaker, not the other way.
Tube amps for classical music FU29 vs EL34
I'm not familuar with the sound of different tubes/tube amps. I have a a Jadis intergrated has 4 KT90's, and has a good sound, but the speakers limit the amp. Soon to be rectified, new speakers with a 87db rating late this summer. But I'd like to get another amp for primary system, keep the Jadis for a second system. I'm looking at 2 tube amps, one has 4 EL34's the other 4FU29's, both intergrated amps. I'm guessing the EL's will sound like the KT90's, and have more bass end. But with classical, I can forgo some "punch". The FU's look like it may offer more complexity in the mids, for orchestration and vocals/opera. Right track?
