What type amp to drive proac response 2.5

The Response 2.5 really sound great with EL-34 tubes. They are also fairly inefficient at 83 db. If you are patient you should be able to buy a used pair of Quicksilver V4 amps in your price range (under $3,000).

In the interim you can power the speakers with something else and sell it when you find a set of Quicksilver V4. That is the great thing about used equipment.

If your room is not large you may not need that much power. What are you using now and what is the rest of your system?

I hope you find a great solution.

My room is 15x20 . I am using a denon flagship pre hdmi receiver . I had a Nakamichi pa7 and c7 which i sold . And used a carver 400t amp. This is all i have used to power these speakers so far . I have had the speakers for only 4 months . They sound better than any box speakers i have owned in the past even with the subpar gear i am currently using . I am expecting much more from them with a tube setup or better ss .

2K budget-go with all McCormack electronics. The DNA series is really musical and reliable, and can be upgraded to current specs by Steve McCormack. Try to get the Deluxe models because they have better connectors and wire.

The great thing about used equipment is that you can keep experimenting until you get it right, and for a minimum cost if you buy carefully. I think you should buy some tube amps you think you can resell with minimal, if any loss, and see how they sound. Quicksilver or Music Reference would be my picks. Preferably something with an EL-34 tube.

You should be able to find a very nice tube amp for that price. 60 watts ought to do nicely.

You can find refurbished Harmon Kardon Citation 2s for that price.
