Just buy a refurbished nait 2 & go fishing.
Problem is early Nait prices has gone mad recently.
A Nait 5i is much more reasonable priced s/h, no slouch either - not the last word in revealing performance but nice universal amp.
No thin midrange provided this isn't coming from source, cables, setup etc.
Another contender for Vgood midpriced amps are one of the half width Rega's.
