SH:
I have been using "TrueRTA" from True Audio for almost a year now. The creator, John Murphy, has recommended the Audigy 2 soundcard, used with a compatible and fast PC desktop computer for the best results. He also recommends calibrating the mic (creating a response profile) for certain analysis functions.

I was wondering what PC and soundcard you used for your analysis, as I believe I remember you are a Mac user. Since I use Mac's in my office, I have had to purchase a PC and soundcard to use "TrueRTA" to it's full potential for my work. My son uses the PC when I am not working with it, so it has utility beyond TrueRTA. GAMES, GAMES, and more GAMES.

Also... Mr. Murphy has contributed to some articles on tube vs. solid state amplification that you might find interesting, or perhaps irritating. They are found at the True Audio website under the Tech Topics section.

Thanks... knowing that you have found this software useful is reassuring to me, as I use it for both my work and home hobby.
