Jim5559 - There may be some equivalent quality items made in Europe & Canada but better? Doubtful. Here's just a few brands that are amongst the very best available in their respective price ranges & American made:
Magico, YG Acoustics, Rockport, Basis, VPI. JBL, McIntosh, Krell, Mark Levinson, Rogers High Fidelity, Audio research, Conrad Johnson, Boulder, Parasound, Benchmark, Constellation, Dan D'Agostino, Pass Labs, Lamm Industries, PS , Audio, VAC Balanced Audio Technology, Ayre, Aesthetix, etc.
That's just a sampling. Of course very few companies can use only American made components but many of these come fairly close.
