Rowland Concentra vs. Concentra II

The II has a different treble character than the original. It's more upfront and explicit. The II is not a hard sounding amp, if anything, the original is a little soft sounding.

Do an archive search, I remember somewhat was quite adamant about the original having a better build quality.

This is the thread I was referring to. Take it for what it's worth.

I currently have or have owned JRDG Coherence preamp, Model 1 amp, Model 112 amp and Concentra I integrated. I think their products are wonderful and with the exception of the preamp bulletproof. The negative comments stated in the post I referenced do not reflect my opinion, but the opinion of someone else. My opinion on the difference in sound between the integrateds is based upon my experiences with the 112 (which according to Rowland is essentially the same amp as in the Concentra II) and the Concentra. Both are high current designs that with normal loads sound very similar except in the treble where the differences are easily heard, but not of an extreme nature.
