There’s a nice McCormack DNA 125 with the coveted SMcAudio upgrade that bring this amp to near SOTA performance levels available on USAudiomart for $1750, which is a relative bargain given the pricey upgrades we’re done in January 2022. Pair this with something like a Schiit Freya (whichever version suits you best) and you’ll have a very nice setup.

If you might prefer an integrated there’s a Hegel H160 also on USAM if you can stretch a little, but I’d go with the pre/amp combo above, and it’s cheaper.
