I've never heard the Ayre pre you're considering, but I did own an Aesthetix Calypso for a while.
You might want to look into Modwright preamps. They are spectacular and should do well with your power amp (and dac). While well below your stated budget, I picked up an SWL 9.0SE and was stunned by how good it was - I find it FAR superior to the Calypso. If you're planning on spending up to $10k, I would think looking at some of Dan's higher end pre's would be worthwhile.
