Does anyone have any first hand experience with this system? http://www.alpine-usa.com/US-en/products/product_acc.php?model=PXA-H100 This past summer I upgraded my entire car's audio, including Alpine's newer ida-x100 Digital Media Receiver that is Imprint ready. I'm an audiophile and I've never been able to get the "right sound" out of this deck engine that I used to fine tune with my older CDA-9855 Glide Touch HU. The same Parametric and Graphic EQ's are there, but it's just not as well balanced and clean as I wish. I called a few different tech people for these retailer's and they all say the same thing. "This one guy I know swears by it" blah blah blah, "Everyone that has used it says its the best sound they could have possibly tuned" etc etc etc. But of course they are going to tell me that because they want to sell it. I've done quite a bit of research on it and it looks like a pretty cool little gadget in all. Uses a mic to calibrate the EQ's, stage, and ms delay times for all speakers to give the music focal point the best sound possible. I was curious to see if anyone here has played around with this before and could give me their opinion before I go buy this thing for $250, or rent it for the same.
