Hi JC;
Thanks for the info. I am very interested in purchasing one of these units. Can you tell me the output impedance (just concerned about matching it with the Bergantino power amp).
Hi Tom,
good question, the 360+ has an output driver circuit based around the 5532 op-amp ... this op-amp is widely known as a quality audio-grade line driver chip - ideal for this situation ... it has very good slew rate, low noise, and can drive loads down to 600 ohms with little distortion ... most power amps have input impedances well above 1k (usually 100k +) even tube power amps with theoretical Zin of 600+ k-ohm can source high current on the positive peak of high level signals - the 360+ will supply the current needed to prevent distortion from happening at that kind of boundary ... send me the input specs of your Bergantino and I'll double check things for you (send me a link if you wish) ... even in the case where you might be using old-fashion 600-ohm recording decks the 360+ will drive those inputs without problem ... I designed the output stage for pretty much any audio interface applications ...
