I will add, at the apparent risk of accusal of shilling (ha ha), that I installed the xovers, hooked the Heresys up to my Fisher 400, put on a Blue Note Coltrane album, and absolutely love the improved sound. The soundstage really opened up.
On Tuesday afternoon of this week I sent my Heresy 1 xovers to Crites for a refurb. They arrived at my house this morning (Saturday). Unreal service! I've installed them and will listen this evening.
This is the stuff that I have used for years on many antiques and furniture pieces. I just applied it to my walnut finish Heresy(s). Lovely product: http://www.kramerize.com
