Yes, the phono run is short, but the run to integrated has to be long and since both devices are single ended, it can't be balanced, unfortunately. I'm hoping a shielded cable will hopefully reject interference.
You might be lucky. I used to have a 30’ run single ended from my preamp to mono blocks. With it running below the floor in the crawl space I used to have no issues. I then moved temporarily to a rental and had to run it on the floor and it was unacceptably noisy so I had to switch to balanced which I’ve been with ever since. You also want to make sure the output stage of your phono stage is up to driving a long cable (as cable LCR will increase with length) - what stage are you using?
I recommend Blue Jeans cable LC-1. Shielded. Low capacitance. Affordable. I have several long runs. No loss of highs. No hum. No noise of any kind. Money back guarantee.
