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…….

Hi Chris
Pure Direct mode disables the video and tone control circuitry, but the signal must go through the Denon's built-in selector switches, volume control and line-level preamp.
So in fact, you are comparing two preamps in series to one preamp (Denon).
If you hear no deterioration of sound quality when adding the AI preamp plus one interconnect, then the AI preamp is doing a great job.
I suggest that you buy a power amp and assemble a second system around your CD player and preamp, strictly for two channel music.
In general, A/V receivers are not optimized to play music, their signal path is too complex. They are designed to do dialogue and movie sound effects pretty well.
I hope this helps
