Upgrade from Proac Response 1SC?

I also had a pair of the ProAc 1SC and mated them with a cary 300sei it was a match made in heaven. If you listen to a lot of vocals, I don't believe you can surpass that reach out and touch you feeling they give you, perhaps as others have mentioned you could go with a different amp. Best of luck

Thanks for the responses and input. I am entertaining the idea of different amplification, but I'm not a big fan of the tube sound. I've heard some very high-end tube systems (Aesthetix, for one) and though I see why people like them, the sound isn't to my taste. There are quite a few amps I can audition locally, so let's see if this might be the solution. As with speakers, there's a dizzying variety to choose from and they all have their own personalities and quirks. If I'm not careful, I can see this turning into a lifetime quest.

Solid state is fine. There's no shortage of good choices. I've used Rowland with ProAc. Some people find that ProAc speakers overall, can be a bit too forward sounding. Rowland can balance that out nicely. Ayre would be my 1st choice. The AX-7 integrated is ideal for your speakers. Pass always a good match. Even the older Aleph series works very well.

So here's what happened: a local seller offered a pair of Proac Response D-2s at an irresistible price so it was an experiment I couldn't pass up. I've spent a couple of weeks with these, getting a sense of what they do and how they differ from the Response 1SCs (which I haven't sold yet and probably won't offer for a little while yet). Yes, the D-2s have Proac DNA, no mistake. However, their balance is quite different from the 1SCs. Gone is the occasional glare the SCs exhibited, but this added control comes at the expense of some of the SC's warmth. I'm not entirely sure I like the Vifa tweeters as much, as I'm not sure they integrate as seamlessly with the woofers as they should. I'll give them a good amount of time to get them and my ears acclimated. All things considered, I do like the D-2s--they do a lot of things really well. Is this the beginning of a beautiful friendship? I'll keep you posted...

I think you would like the 2.5's. Its kind of like the 1sc, only bigger.
