McCormack vs. Pass Labs

I am searching for a very good match for my Dunlavy SCIVs. The McCormack DNA1 deluxe and Pass x-150 are similarly powered and reviewed. There is a decent selection on the usd market. Prices are within my cheapskate sensibilities.
Anybody have experience with both these amps or one or the other on these Duns? Any comments would be welcome and appreciated. Thanks and all have a great holiday season.
