Sounds real audio,
I realize that there’s more to an amp/preamp performance besides the type of tube it uses, however you raise an interesting point. Each tube has it's own sound character that can be affected by other aspects of the component (design,part quality, implementation etc).
I heard a 6c33 tubed amplifier (Lamm push-pull) and I wasn't particularly impressed with its sound quality. Is it the tube or other factors? Would I prefer this same tube in Lamm's SET amplifier (great reputation) instead? It raises curiosity. In my system the 300b amplifier was clearly the better sounding in that specific comparison. The preamp paired with these amplifiers uses 101D tubes which are DHT.
