That guy is stupid, that is all there is to it.
I would agree that McIntosh charges more than I would pay for the quality of the build. I mean unless those RCA jacks are solid high purity copper, PCB mounted... Also for output stages and what not something a little more fancy than some high tolerance Nichicons or whatever could be used. I suppose that places like Reference Mods are what things like that are for... I will admit McIntosh makes very good sounding stuff, not that it justifies the prices per say, always. I mean I listen to it fairly often, it just sounds good, even the not as good stuff that is less than what he bought.
Capacitors, resistors, man do they ever have sonic signitures, only a true fool would believe otherwise. This guy has a few nuts loose. McIntosh make their own IC's? Yeah right... At best any manufcaturer, including Wadia and things like that, will contract TI to make them something. TI makes all the Burr Brown chips I believe. They make all real ICs it seems like...
I tried to join the board just to leave a message saying, "You are stupid."
