Jeff Rowland

Preamp is the same. Power amp modules are what you want to investigate. The Continuum S2 has a Pascal power unit. No idea about 525. Why not call Rowland to inquire.

I called Rowland and they suggested going from my 525 to the
625, which is out of my price range. I'm curious if anyone
on Audiogon has done a direct comparison between the 525
with the Capri 2 preamp and the Continuum S2 Integrated amp?

I think that their suggestion is a good one. I have compared the 525 and 625, and the 625 is clearly a step up in performance. It's more refined overall with improved body, depth and dynamics. The 625 has a more effortless presentation when compared to the 525. Of course that improvement comes with a commensurate increase in price.

I should note that I currently own the 625, so my opinion may be biased accordingly. I'm always looking for another upgrade (sound familiar?), but am having trouble finding something significantly better than the 625 without almost doubling its price. There is no end to the madness of this hobby!
