Hello,
nice outfit. I've found the quickest way to acquire a sound that involves and captivates often comes along with the influence of tubes.
what I felt was an inspiring rig was upstaged when a tube pre line stage was injected into the mix.
later a sleeker more costly tube line stage replaced that one and again, the tangibility and nuance were elevated substantially.
these instances were with SS amps. later a dual mono SS amp akin to your amps.
I got rid of that system then to go fully tube dependent. no regrets there but I could have waited a much longer time to kick the SS amps to the curb. for sure.
there just seems to be something, especially when you slide up the food chain into tube line stage preamps in the class you have named for SS possibilities.
good luck with what ever...
