Well, there's no reason why it can't be discussed, but touchy subjects are best approached by established members.
jcoconnell, what you've done is thrown out a blanket statement about a hellova lot of gear. While the 80's Jap gear (and others, not just Japanese), in general, don't do much for me, and IMHO
does lack in the build quality dept, nearly all the midrange to high-end units (and a
lot of even the budget models) from Pioneer, Kenwood, Sansui, Yamaha, etc etc, in the '72 to '79 era have a build quality that is
outstanding by any measure.
If you repaired these things for a living, you'd know.
...and I know.
I can see you've spent a fair amount of money on your gear, and you have a right to be proud of what you own (and the Hafler amp is pretty cool). But if you think for a moment that I can't get an old Pioneer SX-1010 to raise the hair on the back of your neck with a few tweaks here and there, then I'd love to prove you wayyy wrong. There is a reason that these 70's units are still around, and still sound good.
As an aside, although the Hafler is a great amp, I can guarantee that the construction methods used in 70's Pioneer gear are superior to it.
Lastly, I have to add that I don't really give a rat's ass what anyone else thinks. I didn't buy my gear to impress anyone but me. The more who believe what you believe, the lower prices will stay, so I certainly urge you NOT to change your opinion of Pioneer, Kenwood, or any of the others on account of anything you read here.
