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 think you’ve created your own piece of audio heaven .I can only imagine just how good it sounds.Congrats to you on your well chosen components.
