Which is best American Amp in $1500-2000 range?

Nuforce has new integrated amp, the 9 series I heard were excellent, the integrated has similar sound but not quite the dynamics of the power amps only. To me, the ultimate (moderate priced) transistor amp if tubes do not do it for you. I assume U.S. made.

Figueiredops,
I have been experimenting with Chinese product and I would have to agree that there are points to be concerned about in terms of construction. I just acquired an ASL Orchid integrated which uses 2a3 tubes. It has an O.K. chrome chassis, good binding posts,ceramic tube sockets, a really trick digital readout bias meter and the crappiest feeling controls I've handled in a while. On the other hand I have an Onix SP-3 that is built as well or better than any American product at any price. This is for real. Look it up on www.6moons.com. There are extensive pictures showing all the construction details. I've also had Dared amps here which I thought were very disappointing in construction and Eastern Electric which was exceptional but not up to the standard of the Onix.
Additionally there are European integrated amps which might suit your purposes.

How about a used plinius

Plinius is from Australia. Or New Zealand. One of the two.

May I suggest the Portal Panache?
