Tomic601, that "involvement" you speak of is how I remembered CJ back in the day and what I am now hearing now with the upgraded PV9a with a DRAMATIC improvement in the line stage over stock. The placement, spacing, images and tone just sounds so natural on ALL music! I sure have heard more accurate since there is that added warmth with the CJ but I just don't care, it really "just sounds right". It's got me curious about their current offerings.
