The Audio GD master 19 preamp under $1400, or model 29 if you have around $2k ,they are very good examples ,yes made in China but many parts made in U.S Japan and Europe. 2 big R core transformers , substantial u.k capacitors
and a 100 step relay controlled preamp with a very respectable headphone amp
with adjustable gain to match your other electronics . Excellent value for the money with excellent bass and dynamics unmatched in its price class. I compared the Schitt and nothing there for power supplies to match the midBass and bass of the Audio gd , not saying it is the end all ,but very good quality value for the Money.
