Firstly, I have no experience with either your amp or speakers. That said, I notice you are trying for more bass with a triode amp. I suspect the triode will not give you that bass because they usually cut off the bass in favor of midrange emphasis . So, IMO FWIW YMMV you may be trying to get something a tubed triode amp does not readily give.
Second, I've heard all my audiophile life that SS gives better bass. So you can imagine my surprise when I bought my 1st tube amp about 12 yrs ago and finding out it did BETTER than the SS I had been using the previous 40-50 yrs. Yes, the bass is more "flabby". But having played drums in local bands for 50 yrs, I can tell you that the tubed bass sound more realistic to what I heard while playing with a live bass player (Classic-hard rock). My latest amp, Sachs Kootenay 120 does great on bass...and midrange 7 treble too. I doubt I could go back to SS now.
