Audible Illusions modulus 3A, what would be the next level of up grade?

Thanks for the input.
There are some pre's I have been looking at. I have not had the chance to hear them yet.
 Primaluna Dialouge premium
 Allnic L-1500
 McAlister Audio
 Don Sach's pre
 I do like my Pendragons, I've only had them for 9 months. I appreciate the recommendation and get where it's coming from. I'm in Toronto, Canada. Additional shipping cost, the exchange and 13% taxes on the total amount make it a pricey proposition. If I was considering the DI's (and I certainly have) I would be looking for used, locally.
 I would prefer to stay on topic and keep the discussion to pre amps.

The Calypso was on my short list and there is one available locally.
It is highly regarded in the forums. I did have direct discussion with a couple of people that have owned one and they said they were a little noisy. Noise bugs me. I should still check it out.

there has been some good feedback and suggestions so far. Interesting experiences as well. Thanks.
I seem to be drawn to the Don Sach pre amp, at the moment.
being a newbie on this site, how do you PM someone?
