You use SET amps now, with max power of 18wpc. How much power do you want from an upgrade ? You have a Triode TRV 2a3 amp. Have you considered moving up in the Triode line ? Triode TRV-845SE is an 845 integrated that can deliver about 25wpc. The offer a new parallel 300b amp that is rated for 22wpc. The also a few amps using EL34 and KT88 tubes, for more power.
Given your tastes and setup, I would recommend vintage MAC equipment. With $3000 you should be able to find a pr of Mc30 monoblocks, MC225 or MC240 stereo amps; all having been serviced.
All have level controls so you can connect a source component directly to the amp (or through a passive preamp).
I have experience with many MAC tube amps (currently use restored MC225 and MC240), and SS amps (6100 / 6200 / 2100 / 2105 / 250 / 2505). Many extol the virtues of the MC275. It is a good amp, but the lower powered Mac amps sound better.
A sideways recommendation would be a restored Eico HF81. This is a 6bq5 based integrated amplifier. It will deliver about 15 wpc. I have a restored unit (ALL new caps, resistors, wiring etc). It sounds sublime within its limits. You may also investigate restored vintage Fisher, Scott, Sherwood integrated amplifiers. Key is to be sure any unit has been carefully restored by a competent tech with a good reputation.
Vintage MAC holds value, as do the other vintage units I mentioned. All will probably continue to appreciate in value over time. Benefit here is if you don't like what you hear, you can resell for what you paid or even a little more. Your only cost is time ! How rare is that in this hobby ?
