Turntable interconnects and RFI

I had my JVC QL-Y3F Turntable with Denon DL160 HOMC cartridge connected to my Cambridge 640P phono preamp with MIT interconnects. As I was looking through my cable stash I saw an old pair of unshielded TARA Labs. Seeing how I live in the middle of a corn field in a very rural area (90 miles west of Chicago) I decided to give them a try. WOW ! ! ! The MITs always sounded better between preamplifiers and amplifiers. Apparently these Tara unshielded really mate well with a cartridge signal in an area without any radio frequency interference. This threw me so far off of my expectations that it has posed some serious interconnect questions.
1) What are general guide lines for turntable interconnects?
2) How would someone know these things when living in the middle of a corn field?
Fortunately we have the internet for general information. Thanks to Audiogon I've been able to piece together turntable setup and equipment information. Any help and suggestions will be greatly appreciated.

I would sure appreciate some insights here.
Thank you in advance.

If it sounds good to you, then use it! That's the only insight I have for you. Myself, I use properly shielded cables for all applications.

Thanks. Actually I would really like to know any guidelines for phono interconnects such as are there impedences that should be a concern.

What I have experienced with cables, is that to get the sound you want, you have to use the cable in your system in the application intended. Price should not be a consideration...there are very inexpensive cables that are far better than their expensive counterparts in an application. Take that same expensive or inexpensive cable and use it in a different system, and the cable will sound different. One thing I have found universal is that unshielded cables always sound better than shielded cables...more open and relaxed. There are applications in which you have to use shielded because of noise.
Those little boxes at one end of your MIT cables house an RC network (or perhaps just a capacitor). The network effects a high frequency low-pass filter and also gives the cable a low characteristic impedance. Perhaps the C is having an unfavorable effect on the frequency response of your cartridge. You might want to check Denon's recommendations for capacitance. Your observation does not mean that one cable is "better" than the other.
PRESTO! NOW we're getting to the heart of the matter. Thank you for the suggestion about Denon and capacitance. Now for suggestions on interconnects that could mate nicely with my setup. Afterall I live in a cornfield with no audio advise available other than here.
