Your choice for SET amp?

Thanks all for the info. Jeffreybehr, I should have made the question more clear....

Boa2 I agree with you, I have heard the Duos at length in NYC at the Avantgarde showroom (great place)...they at times have sounded incredible and at times not so good. When they sound bad, it is usually due to edge or too much hardness in the upper mid and above.

Because I have heard them sound so good also, I can only guess it is due to setup and equipment. I think my equipment is good enough...I don't know about my room, but probably worth the risk. I do have the ability to move them wherever I need to....The Db99's are safe, but the potential of the Duo's is much higher.....

I ended up with the DB99's. It was a really hard choice as both speakers are so good. I have had the 99's for about two months now and they have finally settled in. At first they were so harsh on the top end, but the dealer warned me of that due to break in. Now that they have broken in, I am really happy with my decision. Things always sound better in your own home.
