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.

Hi,

i actually use 2 burmester 911 mk3 in mono configuration to drive my Aviors. The speakers disappear! There is no hardening in the treble, whatsoever and the bass is as visceral as i have felt. But I also use the burmester 088 preamp. I must confess, the 911mk3 is partial its own kin.....

......just to add, I have heard the Aviors driven by the Karan S600 stereo amp. Simply superb!

Do me a simple favor before you buy a new amp.  Drive your current amp directly from the Berkeley DAC.  I did this, taking a PrimaLuna Dialog preamp out of the mix, and it was a big improvement.

Synergistic Research's latest high-end cables, the Atmosphere Level 4.  I can't imagine that your cables are the main reason.

Jason,

I've been reading reviews on your Spectral DMA-260 and the reviews say it has plenty of bass. That just means it had plenty of bass when the owner or reviewer used his speakers, not your Aviors. 

If you can remove your pre-amp from the system and go direct from your DAC as 'rvnye' suggests, this would start to isolate where the problem may be. That adds credence to auditioning the Devialet as it will remove both of your Spectral components from the audition.

Make sure your dealer configures the Devialet properly for you or shows you how to use the online configurator. They may have a specific configuration for their demo environment.
