Been listening to the 3300, gotta say, what a peach they are. Missing a lot of bells and whistles of say like a Spec 1, but they sound every bit as good , maybe a little better, hard to say. In a blind AB test I doubt if I could tell the difference. VERY LOW component count, and that's always a good thing ina pre-amp. All in all a great value and a solid piece of gear.
BUT----there's always a but, The traces on this "fudder mudder" board are easier to lift than a PL 0171, or a PL400C board , AND THAT IS SAYING S OMETHING!!. DAYAM!! Lifted 3 myself just on the pots, 2 on the TIS's and one on a cap----AND I TRIED DAMN HARD NOT TOO!!! If your iron hot enough to melt butter it can lift these traces.
