Balanced or Not


I own a preamp which has both balanced and single ended jacks. I assumed that since I was using the balanced jacks I was getting the benefit of a balanced circuit. I have just now realized that just having balanced plug-ins doesn't mean your preamp (or any other component) is "balanced." Just wondering what sonic compromises are being made with equipment which has balanced inputs and outputs but that change the signal to single ended as it passes through it. If you are using the balanced outputs, what good is that if the signal going into this jack is single ended? Why would manufacturers do this? What is the advantage to not following the balanced circuit through completely?

Well I'm not a manufacturer, but you can still take my comments with a grain of salt. I have heard AND owned fully balanced setups. I am now back using single-ended, so obviously, there IS going back. The main reason for going back to single-ended designs was economic reasons.

That being said, my current system is still very quiet and revealing. I will admit that the noise floor using a fully balanced system was lower, but once you factor in all the other noises in a real world listening enviornment, I can't say that I'm suffering.

My current system is about 20% of the cost of my old big rig days, and to be honest, I'm embarassed by how close it is sonically. To think....all those years of what I was sure were "upgrades"... Sure makes me wonder what I spent so much time and money obsessing over.

Tube/SS, Vinyl/Digital, Balanced/SE, just relax, have fun and enjoy the music.

By jove, I think he's got it!!!
Thanks for the topic as I happen to be wondering if Bal or Unbal cables should be used for the female XLR to RCA outputs on my Fostex D5. The cable runs into my Denon DRA- 395.

Any suggestions are appreciated. r
Swampwalker,
Agree!
I`ve heard exceptional sound from both fully balanced and single end RCA systems. Can`t say one bettered the other.
Regards,
My preamp manufacturer mentioned to me that "RCA" is much more "musical" than XLR, even though he provided XLRs on the preamp.
For me it was an issue of "gain" in my system. XLR provided me with the necessary gain (twice the volts over the + and i terminals) and I am pretty happy with it. This is from a very recent upgrade from RCA to XLR between the preamp and amp.
