another what amp?

"What would another amp give me in this scenario. Budget up to 1200 for right amp."

It might help if you briefly describe your current sound, and what you would like to improve.

This would be an elegantly substantial sonic difference IMO.

I know your speakers well. I have the 2's and the 3's myself. The 2's are very revealing speakers. All things considered, I think you will hear a bigger difference if you get a new preamp instead. Also, if you can, I would reconsider the Rega DAC. Its good, but I don't know if it will be that much of an improvement over your Apollo. If you can find a good deal on something like an Ayre K5, it will make a huge difference in sound quality. If it were me, I would combine the money you currently have with what you are going to spend on the DAC and put it all toward the preamp. Down the road, you can follow up by getting something like an Ayre V5 to match the preamp.
