I don't have any experience with the P1-a either, but I owned the whole AA setup-DDE3.0, DTI-Pro, Monolithic supply, Channel Island mods etc. I now own the P-3a(DanWright mod) with Monolithic supply and I am totally blown away. It is in a whole different league from the old AA stuff. I never liked the sound of the DDE3without the DTI Pro in front of it but the P3a is WONDERFUL. Extremely detailed yet smooth and musical with a Awesome soundstage. I am waiting for the software to become available for my speakers (B&W N804's)before I get the P1-a which should be in about a month acording to the company. I can hardly wait! So I guess my answer is YES go for it. $500 is a very generous tradein and the P1-a is many times advanced over the DIT-Pro. Like comparing a Pentium 1 to a Pentium 4.
AA Dti PRO 32 for perpetual P1A???
Should I trade in my Audio Alchemy DTI pro 32 for the perpetual technologies P1A?? They are offering a $500 trade in value. Sounds like a good deal, anyone know or experienced first hand if it really surpasses the performance of the DTI pro 32?? Thanks in advance for your help.
