Assemblage - anyone???

I am curious about the lack of comments regarding Assemblage digital products, DAC 3.1, 2.7, and D2D-1. Although the reviews of these products in Soundstage and PlanetHiFi are generally excellent, Stereophile mostly ignores them, and the comments in these posts seem to be fewer than for MSB Link, BelCanto and others. I have a DAC 2.6 which I really like, and plan to add a D2D-1 for upsampling and jitter reduction. Should I be looking at MSB? Am I missing something? I would appreciate hearing from those who have had a chance to compare directly.
