ATC SCM19 V2 Recommendations.

Whatever sound the stands make, that is added to the speaker.  Mass is your friend in stands so the fact they are filled an don't resonate is good.  42" away sounds good.  Now how far from side walls?

So you are a Brit too!  Well if you ever go back, call them a week or two ahead and get an ATC factory tour.  It's fascinating because it's the way all the speaker makers used to look (winding coils, building drivers, etc ) but almost none look like that now.    Most buy all the parts/cabinets from a third party.  

+1 on the Sound Anchor recommendation, I used them for JBL and Westlake monitors. I still have a 3 leg pair for some vintage JBL’s. What is nice is that you can attain an exact height, and exact footprint for your speaker cabinet. Warning , do not use the blue dots as they will decay and release oils/chemicals into your speaker cabinets. Also their black finish ,while attractive is subject to wear from handling as they mix a course substance into the finish. Cheers , Mike.

Side walls aren't the same.

On the right side the distance is 36" - 42" depending on how it sounds. The right side is all patio doors and windows.

The left side is around 8' to the adjacent wall and then opens into the kitchen.

Haven't been back to England yet, but it is on the bucket list. The last 4 times to Europe have all involved wine tours that start and stop in Paris.

Before you change your amp, streamer or DAC e.t.c the limiting factor here, IMO, is the speaker cables and stands. The Tellurium Black are good, I have owned them, but the Ultra Black II will open up the sound of this system a lot compared to the black. Or get Colin Wonfors LS-25 (Colin was the designer of all the Tellurium cables, and the LS-25 is the equivalent of the Ultra Black II, but sold direct at half the price).

Then put the speakers on good stands. The Solidsteel SS-6. You do not know what those ATC monitor speakers are capable of until you do this.

It seems like two quite expensive ancillary items, but you wont regret it and you will stay off the component swap merry go round.

Paradigm still builds in their own factory too. When I thought I needed to buy a new driver they said, nah, just send the old driver back we'll recone it and bring it back to specs! That was GREAT, and I came to realize the advantages of dealing with an old school, keep it in the house, brand.
