Welcome. The hobby is based on music, I think many of us forget that aspect.I had a pair of STRT's back on 2009, loved 'em. I too had a SS amp and a tube pre-amp. I still have the amp but my pre-amp has changed a few times, in my opinion, a tube pre-amp will benefit your system. I believe I am able to hear an audible difference between a SS pre-amp and a tube pre-amp and I prefer tubes in my pre-amp.Photo above is STRT's and PMC monitior's.
