I use the Onkyo PR-SC5509 ( same as Integra 80.3) with Audessey pro ( we sell this) with Pass labs X250.5 ( other channels Primare Poweramp) and the results are stunning. It is extreemly holographic. I owned the Meridian 800DAXV4 and sold Meridian as well. The problem is that old technique is bettered by new technique. Meridian can play 3d, but it is not his strongest property. Integra has depth like the better highend has. Marantz, Denon, NAD, Cambridge are all 2 dimensional products. This means that there is almost no depth image. 2 dimensional audio I call STANDARD AUDIO. Integra uses new 32 bit burr brown dacs. And the video section is 12 bit and very nice. I would never go for old technique. Surround without professional roomcorrection is always asking for problems and acoustic flaws. With Audessey pro yo become a very balanced sound. A few years ago I owned the Pass XA100.5 and XP20. Now I have a better focussed image. in recordings voices are better separated than with the XP-20. I never heard surround this good.
