Default Which amplifier should I choose for my Proac 2.5 clone?

I am going to build power amp for my Proacs 2.5 soon and I don`t know which to choose. I was thinking of Crescendo Millenium edition and Leach amp, so if anybody had a chance to listen both, please tell me your opinion.

Thanks in advance,

FWIW ProAcs are supposedly voiced on tubes (ARC) and i find even low-powered tube amps to drive them very well.

Default try an aleph

I'm driving some boxes (among them also 2.5 clones) with a biamping of aleph 30 with high bias, and I feel really happy.
Some friends that listened to them, they all agree that is a wonderful sounding system

I am using a DIY Aleph 5 with my clones and they sound absolutely amazing.

does any one try the NAD or Rotel amp to drive the proac clone? Regarding to the power output of the tube amp, how big is that will be okay for the proac 2.5 lone? thanks

The original ProAc 2.5 has relatively low sensitivity (believe its 86 dB @ 1m), and a few strange peaks and dips in its impedance graph. This makes a valve amp not ideal IMO. Rotel and NAD amps would work fine. Guess any amp that can do 50 watts or more into 8 ohms would do fine. My friend has the original, and I've heard them through his expensive and relatively powerful valve amps, and a NAD C 370. Both sounded very good.
