I agree with those who say a long period of listening is ideal. My problem, audio memory. In my case I can only retain an impression for a short time, so I largely rely on first impressions. Changing a cartridge over for example, takes far to long for me to be able to make a meaningful comparison.
The other problem seems more universal. Because our sensory systems are tuned for change, I believe we have an inbuilt, unrecognised bias, in favour of a change in the system. So any change is likely to be seen as an improvement. That is why I use 2 amps. Both are excellent, but I enjoy my music more after a change, just because it is different.
