Best interconnect under$400 for Jolida JD100

At any price I highly recommend Ridge Street Audio Midnight Silver Edition.

i think you will be very happy with nordost blue-heavens,
very musical and neutral cable.....and still have enough left over for nordost pulsar points..for your jolida..to stop resonanse..check it out you might just love the set up.

I am using Empirical Audio Holophonics for my Jolida JD100A(modified by PartsConnexion)with very good results. Another suggestion is the Bolder Cable Nitro ($300/1m). I tried Blue Heavens before and did not like it. The Bogdan Silver IC's ($89/3ft.)kills the Blue Heaven in my system. I sold my 3 pairs of Nordost cables(2 Blue Heavens, one Solar Wind)because I felt cheated and cannot believe that an $89 Silver IC's will kick the crap out of them. The Bogdans are pure silver, with all the Silver goodness, but does not have the glare of other that I tried.

Search here and at AA and you will find reviews and user comments about the Bogdan.

Have not heard about the Ridge Street Audio IC. All I know is that the proprietor of this company wrote a "personal" letter some time ago at AA in the cable forum. Read that article and decide for yourself....

I have had great success with Cat Cables (catcables.com). They have a product called King Cats which come in a silver version. The price is very reasonable and they sound fantastic. Currently I have these between a Jolida JD100 and a Jolida SJ502B with Cat Cables speaker cables going to a set of Thiel 3.5 speakers and the sound is excellent.

What length do you need? With some cables, twice as long means twice the price, so it is impossible to make a recommendation for $400 without knowing the length.
