Nice additions. I definitely agree with the break in suggestions, speaker placement and recalibrating subs (after electronics are fully broken in), etc. But @mapman hit on what I was thinking too. Are the more resolving amp and pre combo just highlighting issues with quality of your source gear (or source material)? The beauty and problem of upgrading critical parts of a HiFi system is that you can now notice the value of other improvements, and the weaknesses in parts of the system you hadn’t noticed previously - what makes this hobby both interesting and a challenge.
