I think I know what you might be up to. You want to experience Lamm, both hybrid and all tube( sorry, valve), and VAC, that's Valve Amplification Company. Both American.
Lamms are just great, they would be my choice if I could afford them at least second hand, or third one for that matter. They sound bloody awesome. I know that many think very highly of VAC too though it probably won't have Lamm's drive and dynamics but will have magical midrange and highs to die for. Lamm of course is extremely good in this department too.
Both are expensive but might last a lifetime.
God save the Queen and her subjects.
