Advise on Long Phono Cable run

“Pro sound operators” are dealing with line level signal voltages ( 1-2V). Here we are talking about 5-10mV at most, even from a high output cartridge. Different ball game.

Don't forget those xlr microphone cables.

@lewm , the phono preamp will be very close to the turntable and WILL amplify the sound to around 1 volt, only then the XLR cable can be used easily to the amp.

Just to kick a dead horse even further down the road, you could choose a moving magnet cartridge that requires a high-capacitance load. For example some types are flattest in response when they have as much as 400 pF or even more  of capacitance on them. Then you could deliberately choose a cable that would give you the required amount of extra capacitance.But if we are now talking about a phono stage placed very close to the turntable, that is the best way to go. Hififan, microphones make a fair amount of signal voltage. I’m not sure what you meant by your remark.

I cut and pasted an excerpt from the description on the Manley Laboratories website, written on their phono stage model, Chinook.  I own one and can speak highly of its sonic performance.  In fact, it's the best sounding phono stage component I have ever owned (having several over the years past).  My turntable is 8 feet from my main line-stage preamp.  I have the Chinook located just below the turntable, with the phono connection being the standard 1.2M length.  I use an Audioquest cable run of 3M from the Chinook to my line-stage preamp.  There is absolutely no trouble running that length.  Zero noise, no loss of signal strength, fabulous sound.  I am running a modest output MC cartridge of 0.6mv, which is a Lyra Delos.  Anyway, this setup works very well and sounds wonderful.  Read the paragraph below and then log on to the Manley Laboratories website for further information.  I hope this helps you.  Good luck on your quest.

Like the Steelhead, each channel employs the two triode sections of a 6922 for amplifying duties with highly accurate passive RIAA equalization networks. In the Chinook, the signal is then directly coupled to another 6922 dual triode serving as the output driver in a White Follower configuration. This output stage circuit is our favorite because of its super-low output impedance and beefy current-driving capabilities. It can drive long cable lengths and difficult loads, tube or solid-state. Bring it on. No wimpy cathode followers here!
