the answer for the ’PC’ meaning Phono Corrector’ is the same as my other answer, but it involves a little more detail to describe my evolution. step one for me was my first ’exotic’ LFD din<->phono cable i used on my CS Port tt and linear tracking arm. next i added an LFD Raptor between my CS Port phono and my darTZeel preamp. and i was using a short set of rca i.c.’s provided by Dave Slagle between the EMIA SUT’s and the CS Port phono. these short (18") interconnects were spec’d by Dave to work in that spot. the tech for this short SUT <-> PHONO cable is unique to that particular place and beyond my understanding.
next i added a second LFD din<->phono for a second arm. everything else the same.
next i switched from the CS Port phono (which had three inputs) to the EMIA Phono Corrector. but this also created a temporary problem since the Phono Corrector only had one input. i was having an MC Trio built with three inputs,
but first i had to determine the SUT values for the Trio, and especially for the DaVa this was a challenge. had to wait for it to arrive then experiment with different SUT’s. we did figure that out and the MC Trio was built arriving in August.
so i had 3 arms, but only two LFD phono cables, and one LFD set of Raptor rca’s. this is when i acquired the LFD dongle. the dongle is a short 11" long contraption that overcomes the limitation of the 5 pin DIN connection which is a limitation of the din<->rca phono cables. the dongle breaks all the rules and actually uses tubes of metal instead of wire, and is very stiff. the last pages of that LFD thread do talk about the dongle and show pictures. to use the dongle i had to add the LFD Raptor interconnects to it. which left me without a LFD cable between the Phono Corrector and the dart pre.
the idea being that the phono cables were orders of magnitude more significant than the interconnect between the phono pre and dart pre. i wanted tip top phono cables first and foremost. so i’m hearing all three cartridges and arms at their best. it did turn out that the dongle + Raptor was the best phono cable. we did some cartridge switching to verify that. more dynamics and space from the dongle/Raptor.
temporarily i used a set of inexpensive but highly regarded interconnects;

meanwhile, i had a friend of mine build me a set of 1.5m ’skunkworks’ rca interconnects which i now have been listening for 10 days which are much better. i’m about to switch the cheap set back in to see the difference.
my reasoning for not replacing the LFD Raptor with another is two fold. first, another Raptor is very expensive, and second, i would need to wait at least a year to get one. hoping my friends handwork will suffice. my impressions are very positive.....but in any case it’s an even playing field for all three tonearms/phono cables.
