Trivista 21 is a dac, so you need a transport; other than that, yes it's far more than acceptable as stock. It has 4 nuvistor tubes which reportedly last 100,000 hours! IOW, no you'll never need to replace them. They are pretty cheap anyway. I'd guess that it would improve your Krell, as your seek. I wouldn't say it strikes me as "lush", though. Cheers,
