Are there any distance limitations when connecting a phono stage to a line stage with XLR outputs on the phono stage?

I’m looking to rearrange my setup moving my turntable from in between my speakers. I’m also in the market for a phono stage. The distance between the two will be about 15 to 20 feet.

Is this distance acceptable without any loss or should I keep it short?
 
Yes, from a powered balanced output stage, a balanced interconnect cable can run several hundred feet. And in on location pro audio this often happens.

But it's not just about the cable it's about the interconnect system.

Balanced output stage >> balanced interconnect cable >> balanced input stage.

Something to beware of: most high end audio products do not support the Balanced Line Standard, otherwise known as 'AES48'. Because of that, they may also not be able to drive long interconnects. Is there any reason why you want an outboard phono section?

My PS Audio BHK preamp doesn’t have a phono stage.
 
Before Ralph re-opened this thread Paul had already purchased a Gold Note PH-10 which has both SE and Balanced outputs.
 
With 2 V output or more from your stage to your pre no prob. From your TT to your stage you will get less performance l- low voltage.

The Audio Engineering Society 'AES48' standard is about how the cable shield is connected at both chassis ends. It's better known as the 'Pin 1 Problem'. It's true that some audiophile products still do it incorrectly, allowing increased noise end interference. The first 'Pin 1 Problem' engineering paper was published in 1994. It took over a decade for some pro audio equipment to get it correct and even now some audiophile equipment is still not on-board.
But it's far from the only circuit design problem.

Well designed line level interconnect systems should be good for up to 300 feet (100 meters).
 
The pin 1 problem was solved long before the mid 1990s- Ampex had that right in the mid 1950s. But
and even now some audiophile equipment is still not on-board.

the word 'some' should be replaced with 'most'...

Here are the most common mistakes I see in high end:

1) the output of the circuit references ground from either pin 2 or pin 3. This causes the construction of the cable to be become critical for best sound- just like single-ended.
2) the output impedance is high- where the circuit should be able to drive 1,000 to 2,000 ohms I've seen some that can't drive anything less than 30Kohms! This has the same effect as in 1), and longer cables can be problematic.
