Do you notice an improvement in balanced vs unbalanced connection with a good amp? If an amp has balanced and unbalanced connections, and I use unbalanced connection, am I supposed to use a jumper over the balanced connections?
Jumpers: some components recommend, some dont require it. Going to balanced usually increases the gain and allows a longer run of cable with less loss.
If everything is proper, no difference of sound quality.
Noise is cancelled when it gets on both hot and cold input of balanced system, and that was the main reason balanced input has been adopted for professional system where the input line can be long through noisy environment.
I can't hear a difference in my setup. My interconnects are only a meter though. For long runs over 6' I'd use balanced but it's usually not necessary.
You can't hear a difference, eh? Maybe it isn't properly implemented. A lot of SS gear is not. They seem like to use the garden variety circuit that comes out of some "cook book", and it leaves much to be desired.
The leads on our phono setup is less than 1 m, and there is a definite improvement.
Improvement vs. unbalanced when balanced input is used can be an indication of a poor CMRR (commom mode rejection ratio) of the amplifier. If the amplifier's front end differential stage is perfectly designed, there should be no difference.
