Integrated Amp Suggestions for Dynaudio Contour 3.4LE

Decware Mystery amp would be great with the Contours 3.4LE.  You would want to contact Steve (http://www.decware.com/newsite/contactsteve.html) with regard to driving the Magnepans.
I have listened to and was impressed with the Decware ZenTorii operating Devore Fidelity speakers.  It's a 25 watt unit, you would want to go with the 40 watt amp/integrated. You may want to read upon this amp, even if your not interested in going with tubes.  It has a very interesting circuit including voltage regulation, also available with cap. and other options.

Really appreciate all of the suggestions. I have some enjoyable research to do. 

bradf, I went away from separates several years ago in the interest of simplicity. With that said, I am open to considering them and would appreciate your suggestions.  Thanks

A lot of you are recommending tubes over solid state. I have no experience with tube amps but I am getting very intrugued.  I am curious as to how people feel about the tube sound and why they like it better.  Also, a number of these recommended amps aren't super high power. Can I assume that more power doesn't equal "better"? Finally, is it difficult and/or expensive to replace tubes?

thanks

To tell you the truth I’d be a little leery about putting a tubed amp with those speakers because both pair present a pretty tough load. IIRC, the Dynaudios are something like 84dB and 6ohms? Something like a Hegel ss integrated, I think, would be a better choice; it can handle both sets of speakers well. And it has the added bonus of a very good DAC inside!

"Tubes have a slightly different sonic character than transistors. Tubes tend to provide a slightly richer harmonic picture of instruments in the midrange with a slight sacrifice in definition and control at the frequency extremes. Twenty years ago this contrast was more pronounced. Modern transistor amplifiers are far more musical than they used to be and the performance of modern tube amplifiers is less compromised."

There are a number of reasons why tubes often give a more liquid sound and sometimes a phat mid-range.  Less so today.  ARC has reduced the number of tubes but hasn't gone all SS.
