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.

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.
Sure thing! Sorry to be a nube, but what is the best way to post system photos on this forum?

Thanks all for the supportivs responses!

It's been a while since I did it, but if you click on your name in the upper right corner of the page, you should get a drop-down menu.  Select "My Virtual Systems" to get started.  
Hi Jason,

If the dealer is local to you and he is a Rockport dealer, have him come out to do the proper setup in your room. Just FYI, I have heard most of the Rockport speakers properly setup, and I don't recall any of them being setup toed out - usually toed in. So, I would say your setup is off. Also, they are a ported speaker, so usually the first thing to do is work to get the best possible bass you can get and once you have that, work on toe in, toe out and subtle movements (closer or further to the side walls and to the wall behind the speaker).
