Din to RCA tonearm cable - which one?

I admit that I have never been a convert of the super expensive wires camp. I give credence to quality construction and engineering. So, I do have quality, shielded cables in my system. Mostly Goertz flat cable and home-made high quality balanced XLR cables. I try to keep my interconnect purchases in the low to mid-100s per pair and keep them as short as they are offered. 

I recently decided to give the Audioquest Diamond 1.5M a try between my MacMini and Ayre QB-9 DSD. This was to upgrade from the Belden Gold I was using. All I can say is WOW! I've been in the tech/computer industry for 35 years and I would have never thought a USB cable could make a difference, but I was mistaken. It's not even hard to tell the difference. 

So, now I'm thinking about the interface between my Linn LP12/Ittok/Dynavector XX2 MkII and Parasound Halo JC-3+. I currently have a Jelco right angle DIN to RCA cable. It was definitely an upgrade over the stock cable at the time (about 12 years ago). 

It got me thinking... I've done some preliminary research including some recommendations in past conversations on this board and I'm coming up with the Audioquest Leopard as a strong contender (I really believe in the DBS as a result of the Diamond!) but I'm open to other recommendations. I like the flat cable science, and my Goertz cables have always sounded the most clear and neutral to me from my single-ended/RCA collection of cables. I know Wireworld also follows the flat cable science so I'm interested in the Silver Eclipse 7 phono. 

Audioquest Leopard 1.2M vs Silver Eclipse 7 phone 1.0M? Any other recommendations? 

The rest of my system is: Parasound Halo JC-2 preamp; Linkwitz LX-521 speakers driven by analogue active crossovers using a pair of Emotiva XPA-5s for amplification. (If you are not familiar with the LX-521 - think upper end Maggies with a strong bottom end) wiring from the JC-3+ all the way through the amps is all high-quality XLR.
