I used a NuPrime IDA-8 integrated with the ELAC UB-5s, thought it was a great combination of smoothness, imaging, detail and dynamics. I did not, however, use the analog inputs, as you would be with your Music Hall front end.
Julie Mullins in her Absolute Sound review of the IDA-8 amp, extensively listened to a vinyl source through the analog inputs and was so impressed she bought the trial sample.
Occasionally, the ELACs go on special for $399 a pair, and I've seen demo Nuprime IDA-8s at $899.
Also, if you can find a dealer who carries both brands, you should be able to get a system price close to your $1300 target.
