Advise on Long Phono Cable run

@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!

Dear @jagjag : It does not matters the type of cartridge you can use it, with 5m. cable from the TT to the Halo RCA phono inputs you will have a " severe " cartridge signal degradation especially at high frequency due to the cable resistance and what you say can happens about that the very low signal is way suceptible to be contaminated rfi/emi and the like no matter waht.

Now, my next advise depends on the importance that the LP listening sessions has to you and how often you listen to LP and even how many LP's you own  and if LP is your main listening medium ( I doubt it because your Halo is not precisely for analo but....) then that TT must be nearest to the Halo ( no more than 1.25m. ) and the other electronics/speakers at " long distance " from the Halo because are all high level units including the signal to the speakers and the Halo output impedance is low enough for you have not problem down there other that all the money you need for the overall system cables you have to buy.

The other solution is that you buy a true balanced phono stage and connect it from those 5m. through the Halo balanced input.

Regards and enjoy the MUSIC NOT DISTORTIONS,

The interconnect cable from my TT uses balanced xlr connectors. It was wired that way at the factory. Almost all cartridges are capable of balanced output. My cartridge has a rated output of .44mV. TT is currently in a temporary location so for a stop gap solution I'm using about 10m of old beat up, cheap, coiled up mic cable. Good strong signal to the pre, (which is fully balanced) no noise and not enough signal degradation to notice unless you were to do an A/B test.

You should be able to have your TT interconnect rewired to balanced easily and economically and be good to go as long as your phono input is also balanced.
