I use balanced ( XLR) connection from my phono into the preamp, and then into the amp. The result is abslutely dead quiet with fully realized performance. I also have balanced headphones and separate balanced headphone amp which can be used easily with regular plugs, and there is an increase in performance using them balanced.
Xor or single ended?
Hi Goners!
I am sure this has been gone over but i seemed to have missed finding it...
What is preferred...A single ended tonearm cable to an orca phono input or a xor balanced termination tonearm to a balanced xor phono input?
Please, if you answer i would appreciate having solid reasoning as opposed to one"s own preferences...
I very much thank all for helping me understand.

Its generally not recommendable to hook up a fully balanced phono system with RCA connectors because the negative node is thereby fully exposed on the barrel of the RCA connector i.e. not shielded, this can have severely negative effects. Most common hook up scheme is pin2 positive pin 3 negative and pin 1 chassis ground - signal ground should not be connected to pin 1. We make mostly fully balanced phono stages with only XLR connectors on them. Even our little gem the Liberty B2B-1 is supplied with XLR connectors if one should wish to run a fully balanced phono system, obviously needing two of them in this configuration.

That's the whole point of using balanced amplification. If the "balanced" preamp uses op-amps at its input and doesn't itself operate in differential mode, then using RCA connectors might be a compromise. |
