Before I went toward tubes, I looked hard at both but didn't audition. So I cannot give you the experience answer you're looking for. However, one audio dealer which a lot of people respect is Gig Harbor audio and they're very nice people who carry Sugden. If you called or wrote them to ask why they deal in Sugden, they might add some data to your inquiry. Yes, they're a dealer so they'll be biased toward what they carry, but sometimes these conversations yield nuggets. https://www.gigharboraudio.com/
