Help! Best amp for Rockport Aviors?

I recently purchased a pair of Rockport Aviors to replace my Dynaudio C2s. My system comprises of a Berkeley Reference DAC, Spectral DMC-30SS preamp, and Spectral DMA-260 stereo amp. My intial impression was disappointing - "hot" treble and a lack of low end slam. I assumed that my amp didn't have enough current to drive the Aviors properly so I auditioned the Spectral DMA-400 RS monos with the Aviors and that combo still didn't resonate in the way I first heard the Aviors (kicking myself for not noting the system). My current theory is that the Spectral gear (as much as I love it) isn't a good match for the Rockports; therefore, I have a bit of a quandary - ditch my Spectral system or the Aviors.

I know that Andrew uses a Gryphon stack to voice his speakers. Correct me if I'm wrong, but I don't kmow of a USA Gryphon dealer and wouldn't purchase a Gryphon component without hearing it in person first.

So cut to the chase: Avior owners out there - what do you drive them with that results in the "softer" treble and bass slam that I know these speakers are capable of. My current guess is to audition Pass Labs.

Jason,
I have the heard the Aviors on multiple occasions with both tube & solid state electronics and I don't believe that the speakers when properly setup have a hot treble. I am guessing that you purchased these speakers used and have set them up yourself. If that is correct, and assuming  they are already broken in, then I think the first place to start is with speaker placement in your room. In my experience with my own Rockport speakers, with the beryllium tweeter in your speakers, I have found that speaker placement within your room is absolutely essential to avoid the sound that you are describing. If you purchased them new from a dealer, then I would definitely back in and work on that setup.

Thanks!!

Any general advice on placement? I currently have them place in a equalateral triangle (my listening position being one point of the triangle) with a bit of toe out to mitigate the "hot" tweater. Am I approaching this incorrectly?

Also, I forgot to mention.that I haven't installed the feet, as I was playing with placement. Do they make a difference in your experience?

And yes, I purchased them used from an authorized dealer so I assume they've been broken in by now (and I have at least a 100 hours on them myself).

+1 on what babybear said.  It would be helpful if you listed your system here and posted pics; from personal experience I can assure you that speaker placement and room issues can have a big impact on sound.
