CD output voltage too high for preamp: what to do?


I have an Audible Illusions preamp which is designed for a 1.5v input signal. I am told that this is standard. My Ayre CX-7e puts out 2.25v. They play beautifully together but I have too little control over volume: I cannot use the preamp vol controls beyond 9 o'clock because it is way too loud. Likewise it is hard to get just the right volume in the limited range available. This is worse with some CDs for reasons I do not know.
Audible Illusions will change the preamp attenuation board for $275, but before I do so I wonder how others have dealt with the problem of newer CD players with higher outputs than their preamps were designed for.

Restock- Beats me, unless they are designed for pro use. Sound reinforcement/studio equipment often employ a matched impedance interface to optimize power transfer. If thats the case it would almost certainly be offered with a balanced connection only.
My AI 3A has a jumper that reduces the gain. Is this an option or am I missing something?
Depends on how much the gain is reduced. My preamp has switches with plus or minus 3db increments. Even at the lowest level of 11db I am experiencing too much gain.
I purchased a pair of the Rothwell 10db attenuators and installed them between my pre-amp and amp and did not notice or perceive any degredation in sound quality........they did solve my gain issue.
