Who are they? What models?

I think old school Adcom amps had balanced line ins, and the Audison VRx has a proprietary balanced system as an option.

The Audison ABS system is really clever.
The female rca's are backward-compatible with non-balanced connectors. The male ABS connectors are in an rca form factor, with an additional concentric ring inside what is normally the signal ground. Audison makes a balanced transmitter which can be used to link an unbalanced signal to any Audison amp equipped with ABS capability. The ABS transmitter obtains +/- 15 volts from the amplifier, and allows unity gain, +3db, or +6db gain. I've also adapted the PG TBAT to run to the Audison's balanced input. Nice sounding kit, and quiet as you could want. (CMMR higher than 70db!)

 

Kevin, I take it you are running a balanced system?

 

the new Hifonics brutus amps have balanced inputs also.

 

Eli, the company I work for in Hong Kong was the Audison distributor from 1993-1999. I've lost track of the number of balanced systems I've installed!
Audison had a really hot, balanced pre-amp, which was introduced at the start of the ABS program. It was called the PA Line. Look it up if you can find one. Sounds more like high-end home audio, than any other high-end car audio pre-amp I've ever heard.

You've heard the saying "The Shoemaker's children go barefoot" ? That applies to me. My own car reflects my modest personal requirements.
AVI separates (MX Direct) running off an Audison LR-604XR. Head unit changes frequently. (Currently CDA-9855)

 

Kevin, I live that saying [img]smile.gif[/img]
I'm fameliar with Audison, as we sell it at our store, but I will look up the PA line you mentioned.
