Hi
@johnstac,
Regarding connecting your setup to the Burson, if you;re using a computer which I presume you are, just use the USB input for now, you can always play with the other inputs later.
A decent USB cable shouldn't run you more than a few dollars or $ 10 though feel free to play with pricer cables.
But from the packing list, at least they give you a USB & RCA cable too which is nice.
If this was regular hifi, you honestly be lucky to get a power cable but that's a whole other story & discussion.
There are no balanced inputs on the Conductor 3X but there is the following aside from afore mentioned USB in no particular order :
RCA
Optical Toslink
BT 5
Any of those would be useful to you as well though unless specificed or added, most computers generally don't come with RCA or Optical Toslink built in.
As said, easiest way to begin is just connect the USB cable, just hope it's long enough for you.
Honestly, Balanced cables are subjective & highly personal, from a technical standpoint, there are meant to be improvements & at the very least is meat to make said signal stronger, doesn't mean it's necessarily better so once again as said, highly subjective & personal.
But in the real world, this will depend on how you perceive & hear sound as well as the physical characteristics related to your head, ear & ear canal shape.
While I don't have the BC 3X or ever consider to for various reasons not related to its sound, I can easily run balanced or single end on my system, both input & ouput though more often than not, I usually run single ended as personally & subjectively, it sounds
BETTER &/or the same to
ME, depending on gear synergy, of course which
@ProtegeManiac has also pointed out in his own experience, he leans towards single ended as well so really it all depends.
But like with the input, feel free to experiement yourself on how you like to listen & not be constrained by others opinions.
In closing, as far as source material is concerned, as long as your source quality, source recording quality sounds good to
YOU & ONLY YOU as it will depend again on how you perceive & hear sound along with those physical characteristics mentioned then you should be at least satisfied, so platform &/or format is largely irrelevant, just depends on what you are after.
Also, pick a streaming music platform which has music you want to listen to, honestly, they're all pretty much the same though for most consumers, Spotify gets the most recognition as well as broader range of ecletic mix over Tidal but that is only what I hear from others who use Spotify, I use Tidal myself & find broad stuff easily enough so it really doesn't bother me but then I have quite a large offline music library to pull from & more often listen to that from my own home setup or on the go rather than streaming but that's just me.
It will also depend on your internet connection & whether you are sharing bandwith with anyone, be it neighbours or within your own household as that can sometimes play a factor on how streaming music is accessed.
Oh & as a last point, whichever or multiple streaming music platforms you choose, just pick the lowest price plan but choose the highest quality option in the settings as where real world hearing is concerned, there is virtually no difference, if there is, it's usually placebo &/or perception.
I have many aquaintances & friends in both the hifi/consumer & pro audio worlds, more often than not, most will just use the basic plan with highest quality enabled.
Given most of these are just given access to streaming music platforms given their line of work, or a nominal fee to access a chosen streaming platform or range of them, it is telling to a certain degree the higher tiers aren't needed.
Hope this all makes sense, feel free to ask more if you need.
Hope you have a great day !
