My recent faves after trying various types have been the new Tung Sol 7581a, but I recently bought a Dennis Had "hot rod" SEP "high output" (12wpc or something depending on tubes) that's around 6 months newer than my current Had "fire bottle," and it seems to sound best with new Gold Lion KT77s. The "hot rod" has more voltage according to Had, and the internals are nearly identical to the "fire bottle" except for an extra Jensen cap or two...the two amps are VERY similar sounding and I'm not sure yet which one sounds better, and I'm having trouble locating any info on what, exactly, is the technical difference between these two amps...anybody know the answer?
What is your favorite tube type?
With so many tubes that do different things and have different sound profiles, what is your favorite? EL34s wonderful PRaT, KT88/6550s smooth and dimensional sound, lush mids of a 300B, detail of a 2A3 or the huge soundstage of an 845? I am curious which is your favorite. What do you like about it?
