Best DAC that has a balance control


I would appreciate suggestions for a digital-to-analog converter that has a balance control.

My system is quite simple. I have a digital source, two monaural amps and two speakers. To feed my digital source to each of my amps I am currently using the Benchmark DAC1. That sounds great, but to really get the proper sound stage I need a balance control and the Benchmark does not have one.

I would prefer not to buy a Preamp. In essence my DAC functions as a preamp.

Suggestions are welcome.

Here is a link to my setup:

Since the Mac is your only source, why don't you just adjust balance in the Mac?
Oops, I thought you meant a balanced configured DAC....not balance control. I don't know one that has balance control..
Sidssp suggests "why don't you just adjust balance in the Mac?"
How can I do that?
Currently I am using iTunes as the software to drive the system.
Is there a way to control balance in the software?

Thanks,
Henry
Henry, Normally, balance can be adjusted from the System Preferences/Sound window but after careful reexamination, I realized that once the output device is changed to "Benchmark 1.0", the balance adjustment is removed. So never mind my early post, my mistake.
