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.

Endler attenuators r the best and easily crap on the Rothwell's. I have both and the Endlers are transparent and flexible as you can set the exact attenuation you need.

Go for these. BTW, just a happy customer

The endler variable attenuators can be used as a volume control or with an active pre amp. That is what I used them for. Put them at your amp inputs or pre inputs if you only want CD volume reduced.

As I said they work extremely well. They look a little ungainly but are totally transparent.

Hi Chuck. I use the attenuators plugged into the amp inputs and on about 8db attenuation.That got rid of the gain noise I was experiencig between the pre and power. The Endlers are truely transparent, no real difference between the attenuators attached and not attached, except for the gain.
I was sceptical as well, but decided to try them and I am very pleased., The Rothwell attenuators are quite coloured and change the sound of the amp too much.

BTW, I don't use them anymore as I sold my VTL 7.5 and using a cj pre amp. The cj has the same amount of gain as the VTL, however there is no noise.
