Amps for Primaluna Dialogue Premium Preamp

You really need to match the amp(s) to your speakers, more than the preamp.  What speakers do you have?

Thanks, Mofi. Monitor Audio PL200 are my speaks. 

I found the Stereophile review of these speakers:

The reviewer found the recommended power was at least 100 watts per channel. He used a SimAudio W-7 and a Primaluna Prologue Seven.

Are you interested in tube or solid state?  And what kind of budget do you have in mind?
