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.

Hi wireless,
If the ice power versions of the JR amps were not better than the old, why would they have gone that way?

I had the JR 201 and 501 monos and years ago had time with the Model 6 and 12 monos too. All good amps. Maybe the sound of the 201 and 501 are on the lean side although with great control and definition.

I have never really understood this idea that the treble in these class d amps is off in some way. I have had quite a few ice power type amps and the gains versus very highend amps are astonishing. I could understand if you were a valve or tube fan you may find them dry and lacking rose tinted specs. I guess taste and balance plays a big part in these. Make sure you feed ice power clean power and have good cabling and source. The treble will be fine.
