I have the Majestic MKII power cable on my SS amp and a Fina MKII power cable on my DAC. Very happy with both.
The Majestic MKII needs at least 8 inches clearance (12 to be sure) and it does not bend easily beyond that. I had the Fina MKII special ordered at 1 meter because the excess cable did me no good on the Majestic. The Fina at 14 AWG is much more flexible than the Majestic but still needs 6 inches or so of clearance. I was apprehensive about the Prima cable because my gear is situated in a basement wall "cutout" and there is limited space behind in which to move and situate cables. If I had to do it over again, I would have purchased the Majestic at 1 meter as well as I had to finesse it a bit and it was just a bit too long, which leaves to you figure out what to do with the excess. The real issue is that your cables should not be resting on one another and separated as much as possible. Only buy the true length of cable that you really need.
I had similar issue with Raymond not answering emails. If you want a custom length of cable, he has to put the SKU online so you can select the length on the drop down box when you order online. He answered my email quickly when I told him I was ready to buy and was waiting for the SKU to be put in place. A shorter length of cable will make the cable non-refundable, so ensure you have measured correctly. Raymond is not going to tell you that the cable you buy is going to fit, or not fit, in your space, and I don't blame him for that. So you really just need to measure twice and confirm you own requirements before purchasing. Ultimately, you need to trust yourself to get it right.
