I'm using a DAC which is connected to a graphic equalizer and goes into my Marantz PM7200 amp. When I turn up the volume on the DAC, at 12 o'clock position the amp already starts to distort even on low volume. First I thought that the equalizer is the problem, as it increases the gain a bit too, but if I connect my Sony TA FE-570 it has no difficulty even with the DAC on maximum volume. What can be the case here, is my Marantz faulty or just has a lower input tolerance? (Both used on AUX input) Thanks.
Thats a pretty high sensitivity for the Marantz for aux-CD-tape-tuner of--
150mv for output usually CD is 2V.
150mv corresponds with (approx ) the value for an old tuner/tape your DAC probably outputs (approx ) 2V .
To really blame your Marantz you would need a very much lower input and then increase the volume using your Marantz volume control.

Thanks for your reply. Managed to find the issue. I made a mistake earlier. I used a special cable to share the input from one source to two amplifiers. For the Marantz and the Sony. Both shared the same input source so the two amplifiers inputs were connected. Not exactly sure why but this definitely caused the problem. Now the lovely Marantz class A sound is back whatever input volume I use. Of course not gonna push it to it's limits.
If the second amp wasn't powered up it would be looking something like anti-parallel diodes and severely limiting the signal.
