Here is one more tidbit, extracted directly from the specs published this far. . . the output impedance of Criterion is 60Ohms for both balanced and SE operations. This may imply that the device will be fully compatible with almost any amp you connect downstream, including tube amps with low input impedance.
LaPierre, I deem myself a social misfit when it comes to audio. I cheerfully object to the sound of most electronics for variety of reasons. . . tubed, SS, and switching alike. And when I conversely like a device or a product line, I do so independently from underlying technology.
As you may have read elsewhere, I am very partial to the current JRDG Capri, which in so many ways -- after a very long and patient 800 hrs of breakin -- has taken what I dearly love in my Ref 3 in authority, lenearity, extension, detail, and harmonic texture, and pushed it a notch forward. What the Capri however does not do is to add an upper-bass-2-lower-treble euphonic glow to the whole. . . and for that I am grateful. If anyone is looking for this additive euphonic warm glow, characteristic of some tube designs, he may be disappointed by the pristine musical rendering of the Capri.
Knowing Jeff Rowland's mind set just a little bit, I can only venture to guess that the Criterion may very well push further in this direction of graceful sonic sculpting, and remain congruent with my own experience of live unamplified music. True or not? Difficult to say until I listen to it. . . but now I realize I am doing exactly what I promised not to do: speculating.
Please note that I use the term 'congruent' very deliberately, rather than 'faithful reproduction' or other facile platitude.
