Recommendation for speaker cable to use with Magico speakers

Congrats on your speaker purchase.

I am a big Transparent fan. They come at all levels of investment. I use Ultra on my system. They are absolutely transparent. 
 

But, I would not even start thinking about cables and interconnects until you have a good 3 or 400 hours on the speakers. Make sure they are well broken in and you know exactly what they sound like. You want to make sure your components are perfect for the speakers. I used to own a Sim Moon 560D DAC with the separate power supply. You will need to decide if the DAC is up to the speakers. The Magico are incredibly revealing. You may feel you need to upgrade your DAC.

Anyway, any changes in components should come before cable changes. If you keep the DAC, you may want to look at Cardas. They are a bit forgiving. 

I use and really like the Audience AU24SX speaker cables.
There’s a used 2m pair on USAM now. Great sound, and you can probably knock few bucks off the asking.

Otherwise if you’re not in a hurry and have cables to run the A1 with, @ghdprentice is right on the money with the let it all break in first advice. 

You are going to get a ton of opinions from people who do not own Magico speakers. Your DAC is fine and look at used cables. I have all LessLoss cables and I am not telling you to try them, as I do not have Magico speakers. 

Budget?
