Advise on Long Phono Cable run

With such a long phono cable you need a Grado MI cartridge which is irrelevant to cable capacitance as stated in the manual, the rest of the cartridges i know require certain amount of capacitance for optimal performance (and it can be too much for 5 m long cable for some MM).  

Actually, for such a long run, you need a Balanced phono stage and Balanced phono cable with XLR, but if you can’t do that simply order any custom length from Frank at Signal Cable Silver Resolution.

I have ordered two sets of phono cable from his for my LOMC cartridges, the reason was the length, i was looking for something longer than usual.

The price is great and his silver cables are highly regarded here on audiogon, buy with confidence.

Your best bet is to move your components near the tt and have a longer speaker cable run.  Keeping the interconnects as short as possible is best. 

Thank you all for the advise. I have to rethink the whole set up.  Houses in Singapore are small and ultra compact. 

I think interconnect cable (or phono cable) within 1.2 m is standard, probably 1.5 max. Very short cables like 60cm can be used too, but sometimes it’s inconvenient. Probably 1m or 1.2m is optimal.

Unbalanced cable must be shorter than 4m max, i would say 3m max.

But balanced cables designed for use on long distance.
This is what professional are using in the studios, on stage etc.

Chakster made a good point. I recommended an MM cartridge, but as he notes, MM cartridges are capacitance sensitive. More so than either MI or MC types. So I agree with his recommendation for an high output MI type cartridge. Second, it goes without saying that you will have to have your cables specially made at that length. Several companies will do that. Among them I recommend AntiCables. In addition, going balanced would have no benefit unless you are running into a true balanced phono stage. A phono stage that just provides an XLR input but is single ended, will not get you all the benefits of a balanced connection. Balanced might be a bit quieter.
