Nandric,
If you are unwilling to attempt a rewire and intend to keep the components you now have (I'm a happy AtmaSphere MA-1 amp owner and LOVE the sound!), I suggest you contact Albert at Space Tech Labs about adding one of his tube buffer/RCA-balanced converters.
My phono stage is single ended in/out. As well, the turntable and phono stage are both on a side wall stand, 10 feet from my line stage. The line stage is balanced in/out for best use with the Atma amps.
I bought Albert's "BUF-101", which is both buffer and RCA-balanced converter, as I have many spares of the tubes it uses (6X5 and 6L6).
Bottom line: I connect a 0.5m RCA pair from phono stage to the "BUF-101" RCA input, and use a 4m balanced (Mogami) cable pair into my line stage. The "BUF-101" is sonically transparent and I have no hum, despite the long XLR cable run that crosses several power cables en route to the line stage. I'd previously tried RCA-XLR adapters - hum city! I love the way my analog source now sounds.
The "BUF-101" costs a bit over $500USD and Albert may may recommend a less expensive of his converters for your particular application/gear.
This option only puts a bit of cash at risk.
Just my 2 cents...
