I have all four and the mta's as far as sound quailty seems better than ppi.they seem to have more range on low&mid range. All amps am comparing factory never repaired. (My test bench is 2 astron 35m , kenwood kdc-x993 ,ppi noise gate and frx-322 crossover and enough polk speakers to make an .25 ohm load) by the way your blog is great am glad some of us ol' school og's are keeping this scene going. I would like 2 see a 200-250 rms watt amp demo. thanks amosmoses.jay123https://www.blogger.com/profile/16757193790350331929noreply@blogger.com
