jrdg concerto vs nuforce 9.02

Bxxxb,

I have heard the Concerto, but not in my own system, so it is very hard to compare to my Concentra. I did do some research before buying my Concentra, and (predictably) found differing opinions. The people at JRDG believe that the Concerto is a big step forward, but of course (with due respect) they need to sell the new version in order to make money. Some of those who have heard both (including a couple of dealers with whom I spoke) don't believe that the sonic differences are great, and a couple actually preferred the sound of the earlier (Concentra) models.

Two things are certain: the Concerto is smaller and runs cooler (using "Ice Power" chips) than the Concentra.

I, like most other Concentra owners, am so happy with the amp that I simply can't imagine there being enough of a sonic difference to justify the added expenditure.

Jp1208,

Lean sounding usually has nothing to do with bass heft or extension. It is associated more with the midrange and midbass where instruments and vocals lack body and fullness. Most SS amps excel at bass, but it's the crucial midrange where music lives that tubes have it all over them. So having bass that "goes right through you", doesn't really mean anything at all in this context....

Ozzy62,
bulls-eye!

@Bombaywalla
ha, ha...can you explain?

Ozzy62, I was switching cables around on the nuforce amps and found that the heavier guage copper brought out more fullness in the mid bass and did not lose too much in the highs. The amps do sound lean in the mid bass with light guage silver but open up a little more. I think with these amps, having a copper and silver mix cable design using maybe 8-10 awg could be a great match. Now that I know what lean sounding really means I will be looking for cables that are a heavier guage. I liked what I heard with the copper.
