Great idea, I'll follow along.
Follow Ups:
Thought up 2 additions over night. 2 double pole double throw switches to add in a 6800uF cap, and a 9VDC battery. The Cap gives you more instant reserve, just to see if it's an issue. The other thing would be a battery supply, most opamps will run off of 9 volts, so to ensure that your power supply isn't an issue, that it's supplying clean power.
Best Regards,

Well, this looks to be DOA. Too bad, I was thinking that some songs sound better through different opamps, so I was thinking that there should be an alternative method to select particular opamps so the rig could remain in place permanently. I am a resolution fanatic, but high resolution opamps sound bright on some songs. With this unit you could voice your songs to your taste. For example, I like to use The Beach Boys "Kokomo" to test for brightness, it just IS bright! With this device I could have a nice Burr Brown opamp for songs like "Kokomo", while other opamps throw a big deep sound stage, and still others emphasize bass slightly, etc. Oh well...
Best Regards,
Lou
