... and that's what worries me Jerome...
The whole point to REW is tuning HT systems, but even using a direct receiver signal, I wonder how poor the acoustic match will be, to a stand-alone amp.
I ask the question because I have been wondering if REW's test tone generation, would mimimize the apparent difference, since it is looking at the consistant frequency of its test tone?
The idea of a portable REW test system intrigues me and I'm just wondering if it would provide reasonably good results? I think it would be cool to carry a single suitcase of gear to someones house, and provide them with a decent analysis of their acoustics, without having to mess with their equipment much.
If the only way to get accurate REW results is to use the main HT receiver/amp - I will drop the idea of a stand-alone amp for REW testing.
Thanks... Hermit
p.s... I still haven't done a real REW test. Everything I am asking could be totally meaningless because I know so little. I am just having so much fun getting set up to do some real acoustic analysis, and my engineering/geeky nature sometimes overwhelmes my common-sense...
ADD: Decided I would enjoy figuring out my own answers. Will be buying a Dayton APA150 amp and a pair of small audiophile speakers (also will use them for small office tv upgrade). Then Im going to run REW tests with the seperate amp and speakers (stand alone), using the Dayton thru my existing HT speakers, and using REW and my receiver in the normal manner. I'll compare the results and to try to figure out how I can use the stand alone set up to make reasonable decisions about room acoustics. I hope to create a test system I can use to test my friends acoustics, without them having to have their high-end equipment. Hope to help them make choices for acoustic treatments, and equipment buying, "before" they spend their dollars... maybe Ill be able to help them spend their money more effectively... ???
