I signed up to audiocircle specifically to respond to a few comments I had seen earlier. Especially around the "DSP", and the speaker performance. Firstly, the "DSP" does, very subtly, adjust the signal pattern between the source device, and the speaker. Each speaker from different manufacturers has unique crossovers, drivers, and cabinet design. It's unavoidable. I have yet to see a speaker system deliver a perfectly flat response curve. The engineers at Axiom know sound. So, they basically took a few of their speakers into an anechoic chamber and measured their response. The solution is an external signal processing device that ensures the speakers themselves deliver a nearly perfectly flat response. I'm guessing these run at microprocessor speeds in the gighertz range, which is far beyond what human hearing could possibly detect. IIRC correctly, the M-80 and M-100 models are already neutral within 1/2 or so DB. The DSP? is just an ever so subtle nudge at some well defined frequencies to get them to achieve even better music delivery. It's a rather miniscule adjustment that. frankly, most people except sound engineers and the "cost is no limit" audiophiles would be able to hear. I've compared my Axiom M80's with several different combinations of audiophile speaker combinations, and they are still the top of my list.
