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.

This is why I was using the XLR cable as well. But the run is so short and Luxman seemed to think the DAC output was too close to the max input level of amp. So was considering switching to RCA to mitigate the issue. Just didnt want to lose sound quality.

Ya I dont think Luxman has those transformers. Ill try with RCA and XLR see what sounds better. Do you guys think the 5.8Volts into XLR input is dangerous for the Luxman? Since it can handle 6volts?

Ya, I think thats beyond me hah. Ill just test SE and go with it, so long as the quality is still there. When i use the XLR connection from the DAC to AMP its 6DB louder than SE. Was my first clue that the Luxman wasnt truly balanced. 

I think a company called Rothwell makes inline attenuators. Like -10db etc. That would lower my DACs output to like 1.9volts...wonder if they change the sound at all.

Shrug, I havent found it warm at all. Pretty dang neutral and clean. So maybe it's what it's being fed that matters. I'm using a holoaudio DAC. 

I have some nice RCA cables coming next week. Nothing crazy expensive but on par with the XLR i have. So we shall see. In the mean time has anyone tried inline attentuators to lower voltage output

Thanks for the article. The XLR is definitely louder than the RCA at the same volume level. The XLR output is 5.8volts the RCA is 2.9

Thanks! I enjoy the Luxman sound quite a bit. I listened side by side with an AS2200 Yamaha and while the Yamaha house sound is good I preferred the Luxman. My concern about the XLR inputs was that my DAC out puts 5.8volts. The luxman accepts 6volts max ( according to luxman tech guy) I was worried about over driving the amp. I even considered buying rothwell attentuators to lower the DAC output some
