Yes, your point is well taken. I`ve only heard Spectral amp/preamp combos. Never with other amps or preamps. I guess, it is what you said about the parts, and their marketing strategy. Hopefully, they are up to date with the 1.3a, and HDMI inputs and outputs. It seems this is a area that companies like Spectral, Mark Lev, and the top guys, are lacking.
The top receiver companies, Onkyo, Yamaha, Denon, Integra, and to some degree Rotel, are best suited with complete home theater features, connections, room correction and everything you need currently for HD.
But, after what I have heard, I would not mind owning Spectral electronics either.
