Im going to regret my cable question

You ask 50 people what is the best XXX component and you will get 60 different answers. It doesn’t matter what kind of music you listen too. Do you want to change cables if you play jazz after just playing rock?

Getting many different responses, which you will, will make your decision more complicated. There are only a few cable manufacturers that sell cables in your price range. Ignore the ultra cheap like blue Jean cables and others because they are lifeless.

IMO, start with speaker cables. There are companies and dealers out there that give you 30 days to decide if you want them or not. So bring in multiple cables (I’ve brought in 6 or more cables when I did my auditioning) and use them in your system to come up with a cable that sounds best to you, not to me, not to anybody on the web, but to you using your system. After picking a brand and model, buy their interconnects, same brand and model, and you will have system synergy.

In looking again at your system I am not so certain that your amp has enough power for your speakers. I couldnt find specs on your speakers, but they look they would favor current.

To compare my experience with steaksters, I found power conditioning to be a detriment in some areas and helpful in others. One step forward one back scenario. But I have good power and live in a rural area. Of all cables I found digital power cords and I/Cs the most impactful. Then speaker cables, followed by power cords. But in none of these situations did I find that cables werent good investments and bordered on component level status. 

If you are looking for empirical data I think you should choose a new hobby. So instead of deciding before listening and confirming your personal bias, perhaps try rsstehno's advice and try multiple cables at once. 

Be careful with cartridge compliance with your Rega arm. 

Enjoy!

I am rather certain my amp has more than enough power. The speakers [4 Ohms]  are rated at 250 RMS. Amp requirements are 100-250 W. All as per manual specs. Michi pumps out 350 into 4 Ohm. So no worries there.

I also contacted both companies directly to confirm the match prior to purchase. Both said it was a perfect match. In fact higher power from the amp is safer than less, as per both contacts at both companies. [Which we all know]

Cartridge compliance?? What? I stick a Rega cart. on my Rega arm. No brainer there. 

Its almost as you are trying to wind me up.

Not at all. I assumed your amp was the Line Magnetic SET so I must have confused this with another thread. 

@squared80  Bingo…we have a winner !
