Interconnect length


I have a new Rega P1 coming in the mail. To hook it up to my system, I will probably need more interconnect length, so I will use an additional 3m interconnect (a decent one) to connect the P1 to my Rega Fono pre. So my question is: is this total length (3m plus the length of the interconnect that is part of the P1) too long, and will it significantly and negatively impact the sound?

If you are using a moving magnet cartridge, such as the Ortofon OM5e which that turntable commonly comes with, you will almost certainly have your upper treble rolled off due to the capacitance of what will be 12 feet or more of cable, as well as the capacitance of the rca adapters. (Moving coil cartridges are pretty much insensitive to load capacitance).

You would also probably be increasing considerably the amount of noise that will be picked up by the long cable, which will then be amplified by your phono stage, making it MUCH more audible than a similar amount of noise picked up by a high level interconnect.

Bottom line: Keep phono cables as short as possible!

From my searches on this topic, the consensus is that if you really need to have a long interconnect, it is better to have it between the preamp and amplifier.

You're welcome.

You can further read about it here. Various cable manufactures were asked similar questions by Positive Feedback Online.

Do take "manufacturer recommendations" and related source information with just a little skepticism. Technically, they know their stuff better than anybody, but there is a conflict of interest.

Since cables and length are such hotly debated items, I'd do some research through "common sense" lenses and don't discount what you actually hear.
