Dear Allan: I think that you loose more than the bass slam on your Krell amplifier. Your tube amp is an equalizer because its frecuency response changes according with your speakers impedance changes and this is not the only problem: the signal has to pass through the transformers and this signal it was a heavy degraded one because the many wire metres where the signal has to pass in the transformers and not only these: when the signal goes through a tube this tube function like a " signal generator " ( by itself ): produce audible harmonics that does not exist in the recording.
I understand that the tubes are right for you ( great for you, no problem ) and I only want to share with you and other people what is really happen on your tube electronics during the sound reproduction, at the end this is what you and other people are hearing ( it does not matter if the tube elctronics are from: Tenor, Lamm, VAC, VTL, CAT, or whatever ).
Regards and always try to enjoy the real music.
