New TT : Balanced vs. Unbalanced Connection?

I have a balanced connection from my VPI Titan to my Van den Hul Grail SE.  In fact, my entire system is true balanced and connected with XLR.  I’ll never go back voluntarily.

An MC cartridge /tone arm set up wired balanced (technically called “floating”) has consistently less noise, even over a short span.  There are side-by-side tests by Pro-Ject (admittedly pushing its balanced units) that show this, over a short 1 M distance.  You cancel out that first bit of noise.

To me, the most important signal to reduce noise is the phono stage.  It’s the weakest and most vulnerable connection.  Any noise there is merely amplified as you go along.

There is a reason why people say the most critical links in your system are your speakers and your cartridge.  Neither is the place to skimp.

So my strong recommendation is to go for it.

The reason to minimize noise at the phono stage is because that stage is called upon to produce the most gain, by far, of any element in the chain. High gain requirement brings the problem of noise to the fore. I have one system that is fully balanced (using Atma-sphere components) front to back, and a second system that is SE all the way. Both require long ICs between preamp and amps. Both are acceptable in terms of S to N. I’d say the balanced mode is not so much quieter as it is completely trouble free in terms of noise. Never a faint hum or a buzz. The SE system will have an occasional hiccup.

I have the Rose rs150b connected to my amp with unbalanced rca connectors and I haven't once thought to myself that I could make it sound better. Which could free up the one unbalanced you have for your phono but if your heart is set on connecting with balanced, don't compromise. By the way, you are going to love the radio part of the rose as you get internet radio from all over the world and can pick which genre you like to listen to.

What balanced gets you, mostly, with phono is a few db of gain. So if you had a very low output cartridge you might find some benefit in going balanced. Also, if you're cable run was very long, like more than 12 or 15 ft you may find significant benefit. Otherwise there's very little. I run a fairly high end analog source and it's all single ended. Look at so much of the super high end Japanese stuff too like shindo. It's all single ended. There will be lots of controversy and disagreement here but my experience is no need for balanced. 

I say, residential, short runs: no advantage, 

I do like that XLR connectors lock in place, but I changed to locking rca's to solve that.

extra gain: I did get a SMALL amount of gain out of my Sony xa5400 CD player's XLR compared to it's rca out, but certainly not enough to matter. No audible difference.

typically, like a DAC, wiser to keep phono stage separate for potential change.

In my case my vintage McIntosh mx110z tube tuner/preamp has a wonderful sounding MM phono eq built in (two inputs). I run my tonearms thru a SUT to the mx110z's MM input. I never think about changing to something else. If it blew up, I would get another without bothering to compare. Friends bring their phono stages here to compare with it. My office, for simplicity, I use the built-in MM/MC in my little Luxman, sounds darn good but never compared it to the mx110z.

Features:

you mentioned bigger meters. They will be fun for a week or two, then they might be bothersome, make sure you can turn their lights off or out of circuit.

check the hidden features, you need to read the manual to find things they don't tell you about, like remote balance .... and, check the buttons on the remotes. Many high end makers don't even show the remote. My Cayin remote is solid aluminum, very nice to look and feel/use, much preferred to boring plastic remote, you use them every time you listen.
