When I initially tested out the AQ 1200D amp on Friday, I was not expecting it to be that good. It measured up very well against my RF T1500-1BD. The bass was there and the interesting thing with Audioque is that the amp was really solid in build. The performance was equally impressive. Even more impressive was the simplicity of the gains. There was a low pass eq, 1 gain, subsonic filter and a switch for the master/servant option. No bass boost. This amp was something straight out of old school in looks, design and build. I cannot get past the looks of my RF T1500-1BD and the placement of the gain settings. What started out as a test is going to be a case of me sampling my AQ 1200D for a while.
