Solid core phono interconnect - Recommend Please

My system is:
Verdier Nouvelle Platine TT
SME M2-12 tonearm
Audio Technica ART9 cartridge
Naim Superline phonostage
Lamm LL2 preamp
Wavac EC-300B power amp
Tannoy Turnberry SE speakers
Speaker cables are Auditorium 23 biwired

It need not be shielded because I dont live in the city area.

I would not gamble on an unshielded phono cable, especially when used in conjunction with a low output cartridge such as yours. Regardless of the nature of the area in which you live, there are a lot of potential sources of radiated high frequency interference within the home, that could have audible consequences. Including appliances cycling on and off, some kinds of lighting, and all sorts of electronics perhaps including the audio system itself.

Also, I see that your phono stage provides some rather unusual capacitive loading options, namely 1000 pf, 4700 pf, and 10000 pf in addition to the much more conventional 100 pf. I don't know what the intended purpose of the three unusually high capacitance values may be, but I'm guessing that the designers might have had particular concerns about the possibility of radio frequency interference (RFI) entering the phono stage and affecting its sonics (high input capacitance would provide a filtering effect at RF frequencies, to some degree).

In general, it is sonically preferable to minimize capacitive loading of an LOMC cartridge. In this case that would mean using the 100 pf choice provided by your phono stage. Using an unshielded cable might make that choice unsuitable.

I have no specific cable suggestions meeting your other criteria, but I thought I would offer those comments.

Good luck. Regards,

Naim products benefit greatly from using one of their external power supplies. Before I spend $1000 on a cable, I would put the money towards a PS. It should make a much bigger difference than the IC. For a cable, you can pick up a good used Audioquest solid core cable like a Jaguar or Columbia. I have both of those, as well as cables that are much more expensive, and they easily compete with, and sometimes outperform them. They're also a good match for Naim. A few years back, I went to demo a Naim CD player, and brought my old player and some AQ cables with me. After hearing my AQ cables on his Naim equipment, the dealer picked the line up the next day.

zd542, sorry I did not mention that I already use a Supercap power supply with my Naim Superline phonostage. All Naim phonostages need an external psu to boot, they do not have any power supply internally.

Having said that, which particular AQ IC would you recommend ?

Al, thanks for that bit of info. I do have couple of shielded ICs. The VDH MC501 and Mogami 2549. Both sound very smooth and musical but lack resolution and transparency. Is it true that shielded cable rob some amount of life and speed from the music ?

Shielding can raise the capacitance, which can decrease bandwidth and therefore speed (resolutIon) somewhat, but it also depends on the implementation. Kimber, for example, achieves high noise rejection while keeping capacitance low with their woven cable techniques. This is also true of Shunyata Research. A third way to shield is to have more space between the conductor and the shield, making for fatter cable.

You probably want to keep this cable's total capacitance at 100 pF or lower. AudioQuest manages to have solid conductors, shielding, and pretty low (sometimes very low) capacitance. Their Angel interconnect might be a good candidate, but I don't know its capacitance. Conductors are highly polished solid core silver, which has 8% more inherent conductivity than copper.
