need help with an audible illusions mod 3a pre-amp

I would first like to mention that this is my first post and I’m hoping for some great feedback, help!

I have been adding to my audio system one piece at a time. My latest piece is an audible illusions mod 3a pre-amp. I have a nice pair of KEF 104/2s, a REL sub and a music hall mmf7. Currently I have the preamp plugged into my Denon receiver and I’m using that as my amp. I realize that the Denon is the weak link.

After listening, to my music hall mmf 7 plugged into the AI mod 3a then into one of the line inputs of the Denon, I’m not hearing much of a sonic change compared to that of Denon’s phono stage.

Is it because of my receiver? Is the denon changing the sonic signature of the Audible Illusions pre-amp?

I have the denon on Pure Direct, which is supposed to bypass all the digital gizmos of the receiver, but it’s not a huge change.

Any ideas??

Thanks,

Chris…….
