I think you are very close to making the wrong choice.
Prima Luna goes out the front door and Cayin goes out
the back. Same Chinese factory or so I have read.
If you plan high usage then a US based service option
will be important. ARC I-50, $5k new. Made in MN.
Rogue Audio-made back east for even less.
If I was going overseas to save money, the LM
line has great SQ. The Wilsenton ?? $2,500
has great reviews too.
The Harbeth like power and current. Do some more
homework before you buy.
