In short, avoid the trap of only looking at certain tube types and topologies.You are in good company. It was Ralph Waldo Emerson who said "consistency is the hobgoblin of little minds." It's kind of like buying from specs. All designs require tradeoffs. If the designer makes the type of tradeoffs that align w your aural priorities and implements the design well, you'll probably like it. If not, it does not matter which tube or which circuit type he or she uses. Of course, the amps operating parameters must match up well w your speakers.
