1. I doubt you will need any shielding. I have used unshielded wiring for my tonearm wires for years with no hum whatsoever (and with a 0.25mv MC cartridge). I would definitely try the wires first without shielding and only resort to shielding if there is hum. In my experience, unshielded wires sound better.
2. I recommend you try something other than V-Twist wire. I have some V-Twist interconnects and I just don't find the sound to be very good. Sure, it checks the boxes on the audiophile evaluation list (smooth tonal balance, decent detail, decent dynamics) but it always sounds synthetic or artificial as opposed to natural and musical. I have tried several RCA plugs all of which sound different but nothing so far makes me want to leave them in the system. By the way, V-Twist needs lots of hours to break in fully. Mine have over 1000 hours.
What wire do you find that sounds musical to you? I intend to try unshielded first especially since this is in my basement without a lot of RFI or EMI that I'm aware of.
For line-level interconnects, there are many cables I would choose over the V-Twist. Just from ones I have owned or used extensively, these would include Wireworld Eclipse (all versions), Wireworld Polaris 5, and Discovery Essence and Plus 4. On a more expensive level, I like Audio Note AN-Vx and Ocellia Silver Reference. And on a very cheap DIY level, the Belden 8402 wire is certainly a decent sounding cable.
For phono wiring such as tonearms, I like 1877 Phono (sold by Parts Connexion) and Discovery Plus 4. For several years, I used some twisted 22g stranded copper wires (sold by Cary Audio) as the hard-wired connections between an outboard SUT and my phono preamp, and they sounded really good. I ended up replacing them with a hard-wired section of Discovery Essence which sounded even better, but not dramatically so. The Cary wires were unshielded and had no hum problems.
impedance is 52 ohms and capacitance is 55pf/ft , why this cable is recommended ? i'm confuse . isn't the 52 ohms is not deserve in audio ( hifi ) interconnect ? 75 ohms is standard for audio as we all know.
The capacitance is indeed quite high, while the 52 ohm characteristic impedance is okay for line-level applications, but not for 75 ohm S/PDIF digital or 75 ohm video applications.
The tiny signal from a low output MC would IMO take years to 'break in' any wires... Just sayin'!
I would think one would need wires that sound great not broken in.. Otherwise the wait for them to break in will be a killer.
I break in my wires with a line level signal (FM or CD on repeat).
