Amp suggestions

i would throw tubes at your system. maybe conrad 12s,

Alternatively, and if you like the Stratos' sound, you could purchase another Stratos and bi-amp yr set-up -- or bridge the Stratos... It would cost less, too.

Why not ask Odyssey if they have any bright ideas? The Dynaudios are nice speakers IMO, worth holding on to!

I heard the Stratos in a friend's system and it sounded decidedly dark in the upper octaves compared to his previous amplifier (from White Audio Labs I think). Now I know that the Rogue 88 rolls the top a bit so if you combine that preamp with a dark sounding amp then it's no wonder that the sound is not very "open". Personally I would borrow another amp to try and see if that changes the sound to your liking... I don't think it's a matter of getting more "current". I think it's a matter of frequency balance, and you need to match your components better to find a more synergistic combination. Of course I could be wrong, but that is my best educated guess.

I have to agree with chuck and gregm. The dynaudios are great speakers, don't replace them. And you do need a high-current amp. Forget about tubes for these speakers, they will never have the impact and openness they are capable of.

Oops, I see that in my earlier comments I referred to the "Rogue 88" when I meant to say "Rogue 99".

If you'd like a recommendation for an amp that's very open sounding and has a lot of pop, the InnerSound ESL amp works great with dynamic speakers as well as ESLs. I'm using them on my B&Ws and the sound is excellent at all volume levels. The ESL amp seems to provide more transient snap than other decent amps I've used without being harsh and it has excellent high frequency reproduction.
