New TT : Balanced vs. Unbalanced Connection?

The biggest difference you’ll experience is most likely using balanced from turntable to the phono amplifier. Since that has balanced outs as well I’d give the phono signal preference and use short RCA wiring from DAC to integrated and save the money.

OTOH, if you expect long runs from component to component, or are in an electrically noisy environment (like a high rise) or money is not object, then the XLR inputs for your CD and phono amp will make sense.

Honestly, given how delicate signals from a phono cartridge are I'm amazed more turntables and preamps don't have balanced inputs for them.  Of all source components in consumer gear, a phono cartridge to me seems to benefit the most from a differential input that is separate from the ground.

Right question, wrong reason. You need to find out for yourself if induced noise from unbalanced interconnects is objectionable to you or not. 
 

That aside, unbalanced (using one of the signal conductors as the signal ground for the other signal conductor) is not best practice. Take the way the headshell wiring brings both signal conductors for each channel through the tonearm tube that is grounded fo the phono stage chasssis (not the turntable chassis). Using shielded twisted pair preserves and extends the tonearm tube shielding all the way to the phono stage. 
 

Oh, and one more thing, phono cartridges produce a differential signal that is not referenced to any ground, so the signal is neither balanced nor unbalanced, but it works best with balanced interconnects. 

Here is some information from the pro world.

To tag onto  what @gdnrbob mentioned. I recently bought gear that is truly fully balanced. This is the best solution for when you need to run long cables. The mfg. (Atma-Sphere) also suggested I convert my Rega P6 turntable from RCA to fully balanced. I did it it and it’s awesome- quiet and sounds great! I have their tube pre with tube phono stage and class d mono blocks and loving it more every day! In case you haven’t already, I suggest you read up on the posts from Ralph @atmasphere. He has lots of good posts that explain the interesting tech side of truly balanced vs just XLR and not actually balanced.

Used to have a fully balanced system, IMO balanced removes some of the noise that gets in the way of the music. Highly recommended. And don't let anyone tell you it's only about long cables. True or floating balanced, both work
