Dedicated phono cable or quality IC


I am new to vinyl and loving it. I have a Music Hall MMF-7, Sumiko Phono Box, Cary SLP50A pre-amp to a pair of Linn LK-85's and Linn Ninka speakers Activ. I have been looking around at upgrading the IC's in the TT to Cary chain. Am using the supplied cable from Music Hall to the sumiko then a spare set of Linn IC's from there to the Cary. The rest are Yamamura M5000's. I figured I could just use a good IC (looking at HT pro-silway) as the output from the MMF-7 is RCA. Now I see that there are dedicated phono cables and am wondering if, in my case, there is any need. I am using the Eroica high output MC cartridge, so I figured it would be less of an issue. Thoughts and recommendations? Thanks

I think that cable upgrades anywhere in the system can give good benefits. I would say the earlier in the signal chain you can upgrade the cables, the better.
Twl. Thanks for responding again. I think my question got lost in my muddled description. I am a believer in better cables for sure. What I am wondering is if I should be looking at a "phono cable" OR if a decent interconnect is as useful a route. The reason is cost. I can get a good IC easier and for a better deal than a phono cable. I saw a Graham IC-30 phono cable for $350 and for the same price I can get an almost new Acoustic Zen Matrix reference II. I realize the "tiny signal" compared to the cdp but will it make that much of a diffence.
I think that with a high output MC cartridge, you will be ok with a good quality interconnect. Input impedance of 47k ohms on the phono input is quite high, and with a HO cartridge, your signal level is not all that tiny. I'd say just to keep the length of the cable to the minimum required, and you'll be fine.
I am going to point you to the following site:

I agree with most of what he says.

A quote from the site follows:

"CAVEAT 1: Never assume a line-level cable will work equally well for the phono signal. My current recommendations should be considered an exception to this rule.

CAVEAT 2: Never assume the same phono cable will work equally well when it is going into a (low-impedance-100 ohm) step-up or the actual (high-impedance-47K Ohm) phono stage. These are very different loads.

The results described below are with the cable going from a step-up (transformer) into a phono stage. A cable going from the turntable into the transformer may have different results."

You can spend hours at this site and save yourself from thousand of $ worth of mistakes

Good luck
