"I have always been on a journey in the audiophile world and recently got a pm from another forum stating that a preamp is a waste of money in comparison to a decent AVR because science basically dictates that in DBT, one cannot hear a difference and in reality there is such a small difference that the human ear would not be able to discern."
The best advice I can give you is to ignore that statement. It's meaningless. Anyone can say anything. Who cares. People bring up DBT's all the time and I always ask the same question. "Can I see the test so I can read it for myself?" Not one time did anyone ever show me where I can see the test for myself. Who knows what they tested? Or even if there is a test at all.
I would say you are doing everything the right way. You're listening to the preamps in your own system and forming your own opinion. If there's a better way to do it, I don't know. In the end, for me, the deciding factor would be sound quality. I know what you are talking about with the volume control working better in the one preamp than the other. I would still pick it if the sound was better.
