If you think you want to go the tube route I would highly suggest Rogue audio. You didn't give a cap on how much you would like to spend, but you said you are not in the position to do 5000+ investment at this time. I started with all tubes preamp and tube monoblocks. My current setup is still a tube preamp paired with Pass Labs SS amps and couldn't be happier. I had Rogue monoblocks at one time but decided to do a "deal" with my dealer and git VTL amps ( bad mistake for another topic one day)I wish I keep the Rogue monoblocks. The Cronus Magnum by Rogue should suit you quite nicely. One thing that is nice about Rogue Audio is you can call them and get supurb customer service and advice. One thing you need to keep in mind is tube gear has a tendency of breaking more often than SS gear dose it just comes with the territory. So along with the investment of tube amps/ preamps you will need to keep a "tube survival kit" especially if you are remote and accessibility to tubes is difficult. Translation be prepared to invest in replacement tubes because when it's -25° and all you want to do is stay comfy warm and listen to music and a tube takes a dump you are sonically S.O.L . Hope this helps you.
