Nice spaekers, congrats!
I have a MTM design with the Seas drivers, so its close to the Tyler's MMTMM
I'm running a Jadis Orch Refer, which is nice but lacks the higher resolution/power of its 2 bigger brothers , the DA30 (I think its been delted from the Jadis line) and the DA60. However both are out of your budget.
I can suggest a cdp, which is the Cayin 17, has dual power supplies, high quality and also a quad of 6922's. Used like 1K, new like 1500.
