Kroo will tell you all those companies are irrelevant because you can't
buy them at Best Buy, in about five minutes. Watch and see.

I still think a homebuilt Marantz 7 clone with good resistors and caps
will beat all but the most expensive commercial High End products if
you build it in a good RF tight enclosure and put a shielded regulated
supply outboard. I'm not saying none will, but the c-j and ARC stuff
I've heard surely does not. Probably better RIAA is available with
multiple stages vis-a-vis Baxandall feedback, but I can't say for sure.
If you have no vinyl the integrated amp approach is probably more
sensible-just fit a good stepped attenuator.
