I read the AudioEnz review some time ago and, just as the reviewer found the Continuum amp to be "inconclusive", I found his review to be very much the same - inconclusive.
I do find it interesting that in another review,the same reviewer unhesitatingly found the Continuum to be superior to the Gamut DI-150 in several areas. ( http://audioenz.co.nz/forums/showthread.php?t=8099 ) Remember that Jonathan Valin said in TAS that the Gamut was the best integrated he had ever heard.
This guy aparently really listens and listens well. His evaluations are complete and well thought through. I guess that his findings are a result of his personal taste. As for myself, I did find the Rowland to be very emotionally involving - but then I don't have platinum ears like the Audio Enz reviewer. (I also liked the Gamut a lot).
What is my take on his review? A very good review - expressing another view on a very fine amplifier. I do wonder though if his amp was fully broken in. (several hundred hours of "normal to hard use" to make it come into its own.) My continuum really didn't become fully "musical" until I played it a lot, and then it became magic.
