Is the SPM/Quatro fil still a good choice

The internal wiring of the Nordost El Dorado power cord uses the same kind and amount of wires as do the Quattro-fil interconnects. If handy w/ your hands I have heard of people buying the used El Dorado PC for a couple hundred bucks and making both the Quattro-fil IC as well as a KILLER set of "quattro-fil" speakers cables, which even Nordost never did! Someone I know overseas has several sets that he has compared to his friend's SPM ICs and they reportedly beat the SPM all around! Thinking of getting a used El Dorado and some Nordost Moonglo RCAs and sending them over.

To answer your question the SPM/Quattro combo is excellent
I have replaced that combo in my system with all Valhalla

The difference is large
The price is large

Hi Ken, yes I feel the SPM combined with the EMC-1 (running direct I assume through the Berning) would be a good match. I use the SPM Reference right now from my cd player to my preamp with very good results.

I will be upgrading from the SPM Reference to a little known cable manufacturer from NY called Stage III Concepts that hand makes some incredible silver, flat conductor cables. I've got some of his Emperor rca's here now and they are superb, very close to the SPM actually. I will replace the SPM though with the Monument series.

Ken1, I also own the EMC-1. I have owned the Quatro fil. I agree with Ejlif in his description of this cables sound. I have also heard many cables out perform the Nordost at a fraction of what Nordost asks for it's name, I mean cable. Listen first before buying. I tried it in 3 systems with the same results. You could not pay me to put this stuff in my system. This is just my opinion. I mean no disrespect to those who enjoy the Nordost line of cables.

I found that the Discovery Essence to be more balanced with my EMC-1 MkII than Red Dawn, Siltech st48b or Pro-Silways.
I also found that SPM speaker cables to be more natural on percussive transients than Red Dawn rev II. I probably WON"T try SPM or QF XLRs as the Discovery Essence is a perfect spectral fit. Detailed but meatier than Nordost.
However, the SPM seems to be an outstanding match with Aleph amps, as they balance each other well.
