Mutec MC-3+

To my surprise the difference sonicwise was unexpected small.

Using a good isolation transformer in front of the MC-3+ did give a much bigger effect.

 

I would like to hear your thoughts as to why the linear power supply had minimal impact but the isolation transformer had much more.

Well, I can only guess - havn't done any further investigation in extend to listening.

 

Might be that Mutec did quite a good job by placing the right regulator at the right point...

 

Avoiding / reducing ground loops is the idea that comes to my mind with respect to isolation transformer - MC-3+ signal grounds are directly connected to protective earth; this requires proper earthing elsewhere which seems not to be the case in my setup.

Thank you. that was helpful as what you say makes sense but I wouldn't have thought of it.
