Thanks for the explanation, much appreciated.

Not sure how that relates to confirmation of whether the 428 is considered accurate or not.
My assumption is not.

With the excel list that I've seen attached (and my thanks to those who update it), does anyone know if there's an easy way to import a unique ID for the albums mentioned into Roon, such that I can import them easily into my library, i.e. without needing to do it one at a time.

861v4/ID40/LPS, HD621, Roon, Quad Artera, Impulse Ta'us, Rel Storm 3. Explorer 2 with HD600s.
