ATC SCM19 V2 Recommendations.

I recently purchased a pair of ATC SCM19 speakers and I just wanted to pick some brains.

I am not interested in advice on different speakers or very expensive options.

I am recently retired, on a fixed income and buy mostly used.

What I would like to get is some options for speaker cables, speaker stands, speaker placement and synergy with my current components.

My room is 12' x 18' x 9' and the speakers need to be placed on the 18' wall.

My current setup includes the following:

Musical Fidelity M6si integrated (220 w @ 8 ohms)

Tellurium Black speaker cables

Lumin D1 Streamer

Denafrips Ares II DAC

Distributed bass array with (2) Rel T5, (1) Rel T7i and (1) SVS SB2000 subs
