Hi Sid, I understand what a tube brings to the table and in your case I will go to an extent and say you need an all-tube setup but a high quality one. S-L is great, but having heard the SHL5 again this time in Spore with CAT pre-power (JL2) I just cannot see a point of having a SS component in the system. You are infact lucky to have a speaker which is a super match for tube amplification, why not make the most out of it ? I suppose you do not assume that all tube amps are typical "tubey" ? In the recent Singapore hifi show, the most transparent and dynamic amp of the show was an Audio Note tube amp driving a pair of Audio Note speakers to concert levels without a hint of mud. Since you are in the process of upgrading your amplification, why not re-consider a super all-tube amp ? Something like an Audio Note, Atmasphere OTL, Lamm or CAT ? If you are a tube guy, having a tube pre + SS power is definitely a compromise, I do not see a reason why you have to live with such a compromise (unless of course you want to keep the option open for a speaker upgrade in any direction).
