Recommendation for tube amp.

I owned the Triton 1s for a year. You don't need that much mustard as it's just a couple mid drivers and a tweeter (woofs are powered). I used a variety on mine, including PrimaLuna and Rogue Cronus Mag amps, both tubed. 

But to your question: van Alstine - UltraValve will set you up for life, or the life of your T1s anyhoots. 

Last year at Axpona the Primaluna room was paired with GoldenEar speakers. I believe those were the Triton Reference though I’m not sure. Amp was Primaluna Dialogue Premium and preamp. That combination sounded really good. I was quite surprised because I heard the Triton 1’s at a local dealer the weekend before and they didn’t do a thing for me (at the dealer they were mated with cheaper solid state but for the life of me I can’t remember which brand). But at Axpona they were really singing well with the PL stuff. Used you could probably find a PL Dialogue Premium within your budget. Best of luck.

i would stretch to purchase an ARC Ref 75 non se version as it looks like you could take a truly great amp home for under 4k. it’s one for the long haul. 

Scott,

 I’m intrigued by your recommendation of the van Alstine.  Did you use it with the Tritons? 
It certainly is affordable. And they say it’s inspired by the old Dyna Stereo 70 which I owned and loved.

I have a pair of Quicksilver Mid Monos and they are great amps for the money.  The latest version has been improved with a number of upgrades, specifically independent bias adj for each tube and improved transformers to allow use of KT120 and KT150 tubes.   I drive mine with a c-j Classic 2SE and it's an awesome combination.   Have used speakers that are 87 dB sens , 90 dB , and 99 dB efficient with excellent results.   Rock solid reliable, you won't be sending it in if a tube fails like an ARC amp.
