Some years ago I had the opportunity to test several bookshelf speakers, and settled on the ATC SCM19’s for their clarity and detail. I paired them with the ATC SIA2-100 amplifier and my Rega Planar 6 with the Fono Mk3. Later on I added the ATC c1 subwoofer and ever since, I cannot live without it. Not visible on this picture because they are hidden are the Innuos ZenMini mk3 and the Chord Qutest.
I love my scm19s but I paired them with the rega elicit mk5 cause when I demo’d the sia2-100 it made them sound a little too flat for my liking
