08-11-2018 11:00pmThe 625 and 725 are the only JR linear amps as riced1 pointed out, but what you may have heard from 625 was the (switch mode) smp power supply they both use, the artifacts could give you the impression that it’s Class-D. As they complained about in the above test I posted.I was a big fan and owned many Rowland amps and pre-amps for a long time and ever since they went to the Class D - Power Correction Mode technology, in my opinion, they lost what one was beautiful sounding gear. Too bad as I was looking at their 625 amp and took a listen and to my ears all I could hear was that Class D sound.
