Anyone use McCormack with older Infinity?

Yes Bill- this would be a very good match.

As a previous owner of a DNA-2 LAE and now a current owner of a DNA-2 Revision A, I would suggest that if, per chance, your speakers don't match well with the LAE, you might consider looking for new speakers. But I would not anticipate any problems.

Nevertheless, as good as the LAE is, you might consider sending it to Steve McCormack for a Revision A rebuild.

-IMO
