-@lalitk I’ve had this system, in roughly this form, sans those woofers, for a long time. The Lamms I’ll probably never part with; the Avantgarde is not cost effective these days and if I have to replace, I may go another route. Yes, the big woofers made a difference, but believe it or not, those Koetsus really made a difference in the bass. Previously, I had (in order) a Lyra Titan I, an Airtight PC-1 and Airtight Supreme with this system (at the time I set it up I had the original Parnassus with the platinum magnets but it was dated).
All were "good" cartridges, but the Koetsu really gave me something the others didn’t-- fully fleshed out bass with tonality and a 3d quality that wasn’t boomy or bloated but taut and articulate with the same kind of holographic quality their cartridges are known for in the midrange.
I think this, too, is a system variable with arm and the rest of the system that can exceed expectations or disappoint, depending on the system as a whole. In my case, they worked synergistically and make the woofers sing. Thanks for the nice words about the system. I spend most of my time, money and effort on records rather than gear these past several years and get a lot of enjoyment from listening.
