I used a pair of Reference 8.02 amps to drive a Gallo Ref 3.1 for about two weeks. Do not take the short audition period the wrong way! At the time I already had the NuForce S-9 speakers -- which I was inordinately fond of -- and was playing around with other speakers just for fun.
Anyway, during the auditioning I heard several things:
- Gorgeous midrange, this was most surprising to me since I was expecting to be blown away by the tweeter instead.
- The same treble response I had heard in Gallo dealers before, namely superb soundstaging (far beyond the speakers) and extension. See below for more comments on the treble.
- Powerful and tight bass, the kind I would have associated anyway with NuForce amps driving a large driver in a sealed box
- Very good dynamics: the Gallos never seemed to be running out of power within the apartment-sensitive volume levels I was playing them at.
I actually never liked the Gallo CDT tweeter, even in carefully set-up dealer demos with far more expensive -- and "traditional" -- gear. To me the CDTs have always been too "hearable", like chrome detailing that catches the light no matter how you turn your head or move around. Perhaps the dispersion of the tweeter doesn't match with that of the midrange balls. Moreover the treble never seemed to meld with the character of the midrange which is full of body and flesh; instead the treble felt more pure and honest. My system is not kind to this sort of treble response, and the 8.02 surely didn't cut corners in the treble either.
Having said that, I know that many reviewers love the extension of the CDT tweeter and others like the Gallos with tubed amps, which lead me to believe that many people either have trouble hearing high treble or have discovered that the natural roll-off of many tubed amps complements the CDT's extension. Or use them in significantly bigger rooms than mine or that of the dealers who I've visited.
So the confused message I have for you is that the Reference 8.02 drives the Gallo Ref 3.1 honestly and dynamically. My guess is that you will be deciding whether you like the Gallos' sound rather than that of the NuForce amp!
Hope that helps!
