Get a nice tube preamp. I like tube power amps, but also love gobs of power (even on those 96dB Tannoys), and it costs a LOT more to get there with tubes (like my VAC Master 300's). And after all these years, I have to admit Tannoys do great with either tube or SS power - they're truly ambidextrous. You might need to shut off the supertweeters for SS amps though - ouch! And the pre/power equation absolutely might flip if you're a low volume listener - I'm not 😅
Tube DAC - tubes are just an extra thing in the way, and I'd just let the DAC do its thing without a superfluous tube buffer. I suppose I'd have to hear a Lampizator to be properly qualified to an opinion here, but I've never invested enough in digital to go there.
