Audiophile sound quality from a more "mainstream" company?

When I bought a set of Heresy IVs to replace the IIIs I was impressed by the IVs better construction and thought the porting for 10hz lower frequency response was a great idea (although I use 2 REL subs in this heap, so...meh...). After listening to them for over a month with a frown (figured they were still breaking in), I narrowed the main issue down to an upper mid "honk" or aberration in piano music mostly as I listen to a lot of jazz piano trios. Man...I wanted them to be great, but put my trusty IIIs back in a realized how much better they sounded. More coherent, smoother...just better. Damn. I think the IIIs mid horn is simply better...titanium instead of plastic driver, more complex horn throat design...or something. Sold the IVs, still very much enjoying the IIIs.

Not this week.

Sony ES; Pioneer Elite; Technics (now, not the stuff they was making in the 1980's -- SL-1200 Series Turntables were the only exception).

I’ve had a Cambridge Audio Evo 150 for about a year now. .  My assessment is  it is very competitive and  in the same league in all regards. 

Are the following mainstream?

Rotel
NAD
B&W
Martin Logan
Klipsch
Dynaudio
Cambidge Audio

Some of them have over 100 million a year revenue
