This is crazy. I logged on tonight and started reading. When I logged on there were 26 pages of comments. I've been reading for maybe less than 20 minutes and now there are 30 pages in this thread -- truly crazy !!! . . . so many comments I may never catch up (only on page 7 right now, so forgive me for the following comments, as they may not apply by the time I catch-up).
All said and done, this is truly a controversial unit. Most brand amp power ratings are given @ =/< 1% THD distortion. At that level, in bridged mode, this unit has pretty great power ratings, especially for its price. However, what I was hoping for was a basic amp, simple plain fascia, NO volume control, and one balanced + one unbalanced input (but very glad to see the 12V trigger, and gain settings choice). When I saw the pre-release photo on Topping, I thought this is my next amp (or two); a real bare plain-jane power amp w/ hoped-for outstanding ratings (not the semi?-integrated one we see now). But, I'll have to admit, in the end, a little disappointed. A little more power, a little LESS features, and you would have had me at HELLO!
