I am not going to try to talk you out of a change as only you know what will work for you but I heard the HI-Fi+ analog demonstration at RMAF this past fall (recap in issue 55 I think, I can check for you) and heard an HRX, VPI's top of the line, sound alternately vague and boring or captivating and personal depending absolutely on set-up. It could be that yours has drifted out of alignment in one or more parameters. Let me know if you need more information from me regarding this article or if you think it may help with your issues.
