balanced vs. unbalanced sound quality


hi all i just got a theta dreadnaught amp and i currently have it hooked up through the unbalanced inputs.

i dont know very much about this topic, so i was wondering if i got balanced cables, would the sound quality improve? i will be using all 1 meter cables.

i know that higher end cables will sound better, but lets just say that the balanced cables would be of the same quality as the unbalanced.

thanks all,
cheers

My experience is this. If your system is fully balanced from source to speaker terminal, as is mine, you'll probably get better sound using balanced interconnects. I tried some inexpensive XLR interconnects on a lark, just to hear what balanced might sound like. The improvement over my expensive single ended interconnects was immediate and material.

It is system dependent. But in a system where all the components are fully balanced, balanced is the way to go.
Egrady,
You are right, the true is either type of cable may be the better solution depending on the system`s make up.
In certain configurations the RCA cables will be equal or better in sound quality. Audiofeil was right in saying it really does depends on the'individual' system(components involved and circumstances).For limo`s particular case the balance was the superior choice.There is no universal right or wrong here.
Regards,
So much bad information concerning balanced audio and the advantages. Balanced audio is not 2 signals, one 180 degrees inverted to eliminate common mode noise. That technology is used for digital transmission to null out any interference caused by environment or more importantly, other digital signals in the same cable bundle. Balanced audio utilizes 2 identical signal path circuits, one for each "leg" of your audio signal. The foremost advantage is that  there is no congested ground path for all signals, audio and power supply to distort the audio signal.  All currents through a ground path drop voltage due to small resistance.....noise!   Picture a toy slinky...both hands moving for balanced audio...Picture the same slinky attached to a table top on one end and only one hand moving for unbalanced audio....I'm not saying the difference is "huge"...but it has nothing to do with differencial noise elimination.
I'm currently looking for a cdp that will blend well with my krell kav-300i and vanderteen 2c's. I recently picked up an NAD S500 cd player based on positive reviews and described sound quality. It sounded better with the krell versus other players I have tried (i.e. Rega Apollo). Both the krell and S500 have XLR outputs, so I decided to give it a try. Wow, the difference to my ears was rather substantial. Yes, there was a noticeable increase in volume, but more importantly, there was a more neutral sound to the music. It was much more even sounding, and was exactly what I was looking for. I kept the S500 connected in RCA as well and kept going back and forth, adjusting for volume each time. There was no comparison in this particular setup. The XLR connection was much better and provided a more even presentation of the music. My question to all this is: How is this possible?
