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.

You may want to look into the Aesthetix Calypso. A fantastic preamp from a great designer.

Backert Labs.

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.

I haven't listened to one in a long time, but my impression is that the 3A is very good. It may be hard to beat for near the same kind of money. It does have a ton of gain which isn't an issue for vinyl, but might make finding a good match amplifier wise more important than finding another preamp that is "better".
