Jeff Rowland


I was reading in Stereophile about how the older Jeff Rowland Amps sounded great and were classics. The writer said Rowland was good up to the Concentra II but not the Concerto and anything with "rounded corners." I think the Concertos were where JR started using class D amps. Is that the case? Do all models use Class D now?

I'm sure I don't want anything with class D at this time as many reviewers have commented on the treble as being glassy or something wrong with the sound of it. The highs are what make or break a piece for me so I'm not going anywhere near Class D right now but am considering giving Rowland a try for a third system I'm building.

Brian, I agree. I got my answers on the JR "classic" JR products and kind of steered the thread to a class D discussion.

Guido, I think you miss my point - meant to be mildly humorous - about Krell and McIntosh. I was simply acknowledging the fact that even good gear gets bashed regularly. I'm open minded but no local dealers here for Bel Canto and JR. I may buy a used piece to try.

One area I think Class D may work well in is for speakers that need a lot of power with low impendance drops. Those characteristics apply to a lot of high-end speakers including a pair of Aerials I own.
In that case I agree. . . it's going to be a few years before a few current switching designs become 'classic'. . . let's meet again in 10 years around drinks. . . we'll be able to share some accumulated wisdom by then. G.
Wireless, I suspect you may be correct. . . I have herd reports that the JRDG 312 for example works very well with the Ariel 20Ts as they have some of the sonic characteristics of my Vienna mahlers. Other class D amps with low damping factors like the JRDG 301 monos may not. Spectron probably will. . . Bel Canto I am not sure. G. work as well. .. but this last is just my guess.
