These little Jensen transformers are normally used. They also add a little gain, making "balanced" louder which is whey some people think it sounds better. They are about $100 each and you need 2 per amp.

Are luxman integrated amps truly balanced?
Hello,
I have the Luxman L-507z integrated amp. Sounds excellent. There are 2 line inputs on the back that are listed as balanced inputs (XLR). My DAC has balanced outputs (holoaudio spring 3 kte). Am I wasting my time and money getting good xlr cables? Also the DAC puts out 5.8volts. The XLR inputs (according to Luxman) can handle up to 6volts. Using RCA outputs/inputs the DAC puts out 2.9volts and the amp can handle up to 9 volts. Am I in danger of harming my amp using XLR ? The DAC has no volume control. The cable run is very short...3 feet.
