Great idea for a discussion. Unfortunate that almost no one's willing to name names. I suppose that, if one buys a thing, one's invested in it, to some extent.
So here's one: Audio Research's non-tube power amplifiers. I had a pair of DS-450m amps, and they were mediocre at best, while bearing the usual ARC mark-up. This criticism does not apply to all ARC gear: I have two sets of their tube amps, which perform well enough to be a value despite the price. Nor is it a criticism of class-D amplification: Peachtree products (w/ ICEpower doing the heavy lifting) are pretty great, and blow the (much more expensive) ARC class-D gear out of the water.
