The ATC P1 is the same amplifier module that is in many of the world's professional studios - see the ATC website for an astonishing list. It could drive my cellos with ease. You must have a fab system if it not up to spec with other components. I have not sold mine (it is running my office system and I consider it is not outclassed by the Daniel Hertz M6 Pre-amp - a good match actually). The only reason it is not running in my man rig is that I got offered a Pass 150.8 power amp at a good price.
MAIN COURSE. I have sold my Triangle Cellos and pulled the trigger on the Magico A3s. Good Grief! Midrange: As fab as the Cellos were in midrange this is a large step up. Piano sounds closer to a real piano. Same for guitar. A bit less difference with the viol family and human voice. Less again with woodwind and brass but still a slight improvement. Treble: Not much in it so far. Some better clarity but the jury (of two) is still out. Bass: I had no idea! Bass is now totally coherent and better. It is like there is now a foundation of a coherent structure rather than 'oh bass is better/bigger'. I cannot comment on soundstage as I have not as yet optimised the positioning of the speakers. So far so good!
