Help! Best amp for Rockport Aviors?

HI Jason,

You are welcome and glad that you have got your Aviors positioned more optimally in your room. Assuming that the recordings that you are using that have the "hot treble" are not recorded that way, then I'd suggest trying the following:

Staying with your current Spectral amp, adjust the speaker positioning in very small increments. Start with adjusting toe in perhaps a half an inch (either more toe in or less toe in). And then listen with to see which is better - where you have them now or with slightly more or less toe in. These "micro" adjustments will allow to really dial in the speaker with the room. If after trying this, you still hear a "hot" treble on recordings that you are certain are not recorded that way, then play with the other amps as well and see how they sound.

Wait, you have these large, rear-ported speakers 12 inches from the rear wall?  Is that right?  Personally with the size of your room I'd have them at least two feet into the room measured from the rear of the speakers, and given spacing between the drivers I'd also experiment sitting more than 10 feet from the speakers to see if it gives the drivers more of a chance to become more coherent.  Best of luck. 

Try the New Spread Spectrum Amps Junior Godzella . Best SS. amp I have heard for $$$ 3500 retail

I had Rockport Aviors, had a tube Cary 05 running into Boulder 2060.  

I would say, with the Boulder, the Rockport were not bright.  Sounded just right.  

I do miss them.  But I was looking for something else.  

Ditch the Spectral.... Try to get vintage  EKSC 2a versions in monoblock iteration.. These are of the  legendary Jon Iverson fame amps... Still to this day, few solid amps can touch them for the treble delicacy and bass slam... I believe eagle audio in Kansas still able to supply a freshly refurbished pair. I think configured in mono they are about 2 grand. Just try to get 2a version, they are best sounding ones among three version. We had comparo session awhile ago  at my friend's set up here in NY and the stereo version of the 2a in my non humble opinion (and among very experiences music nuts who were present there) it handily bettered Spectral and Levinson amps that my friend had intended to purchase. Now a pair of EKCS are his summer amps , his winter amps being Tube Research Labs 400 (those are among top 5 amps), just to give you a point of reference. Short of custom designs, I doubt many solid state amps can better them in dynamics and slam, etc., regardless of price... Don't be tempted by the larger 7 versions, those look great but are not as good, although still better than Spectral I d say... Ditch the Spectral preamp, and try to audition the Croft 7R preamp with separate  regulated power supply. The British pound/$ is favorable now so you should be able to get a decent deal from England. The  US distributor overprices them by alot here, but Brit dealers will deal and provide units in US voltage...
