Dynavector xv-1s for Scoutmaster Sig.

I've enjoyed a Sumiko Blackbird now for some time on our Scoutmaster Sig. It has been at the heart of what has brought me back to my vinyl roots, and am grateful for this. As a professional musician, I am keenly aware of timbral authenticity, soundstaging, and hearing into/through a performance, thus I'd like to see what cart upgrade direction would provide the best means to this, and match well with our table. From research, I'm particularly interested in the Dynavector xv-1s, as it seems to be designed with these objectives, yet on the pre-owned market, comes within my budget (circa 2400). There are of course many discussions already on the xv-1s that have been interesting to read. A bit concerned only in that I've been advised by a few fellow audiophiles that the jmw9 signature arm cannot provide all that xv-1s is capable of producing, and should "buy to the arm," sort to speak. Any thoughts and/or experiences with this combo?
