Two box preamps: Cary SLP05 vs. Modwright 36.5

I am wondering if anyone has been lucky enough to compare these two preamps. I am looking to switch to a balanced preamp to take full advantage of my Platinum Modwright Transporter. Just based on specs, I like the Cary better due to its Headphone output, but that's not really a limiting factor.
Thanks for any opinons or insights.
