I owned Rowland gear in the 90's, then I made a long stop from 2001 until 2011 because none of those newer units moved me. In a way, power, but dead. I bought Coherence II.2 + Model 2 with Battery Power Supply 2012 and I think, they have indeed something to do with a musical reproduction.
Marketing will let us know that the latest is always the best. But you don't get a definition of "best". Instead you get a lot of technical explanations what parts are inside but you don't know what they do. A good Design is very often a combination of knowledge and pure luck. There is absolutely no guarantee that the next unit from the same designer will be better. Different of course, but better? There are endless examples out there, countless Audio Research units, Cartridges, Tonearms .... and so on. The old Pass Aleph amps beat any new in any second of the day when they are connected to a matching speaker. They can't drive ultra low loads, but is that a proof that they are worse?? Isn't it more intelligent to avoid such a Speaker Design and to look for something better....?
I listened to Criterion and I decided to go for Coherence II, but my priorities will not be shared from everyone. Most think, when they hear a difference, that this difference is better (for example, louder is always better, faster is always better.....) but a musical reproduction, the illusion of being part of a Performance is something different. Spectral for example is fast, but none of their units have something in common with music. It is the way it is.
Rowland gear is good, personally I don't like the Switch Mode Power Supplies, the sound is going on my nerves after a few hours, but there are others out there who like it more.
The Coherence II has a very unique internal Design with some very, very expensive parts and intelligent technical solutions. The XLR input and output are different from the "old" ones and the newer ones, so when you compare them you have to get the right cable terminations :-)
Specially when a Cadence Phono is used also (a very amazing unit, but wrong cable termination will rob a lot of its abilities...).
It is no secret that the very best sounding Rowland amps were Model 2/6/8/9.... some - intelligent - Dealers announced the 625 Model as the next best units after Model 8.... Marketing is one side, proof or time another....
