Looking for Integrated Amp for Dynaudio 1.3 MkII's

Wyred4Sound STI-500. $1995, Can't do much better at that price, IMHO.

Yes, they like lots of SS juice.

Icepower works well with these Dyns.

The Wyred integrated is where I would probably look as well.

Right now I'm using a VTL IT-85 integrated with my Dyn Special 25's. It sounds surprisingly good and drives them well. I have tried various solid state - Classe', Luxman, but really prefer tubes...

With those speakers I would not go with tube gear. They already have a beutiful smooth sound. Special 25's are very different. For contours I would go with solid state. You will definately get significantly better sound with a better amp. The NAD is a good budget amp, but you are missing out on what those speaker can do, for sure. I would consider a Plinius 9100 or 9200 if you can swing it. Also consider Bryston B100. Another good choice would be NAD M2 or M3. If you have a tight budget look at the NAD C375bee. No better amp for that money and it will make your Dyns sing.

I have the NAD M3 and right before this I owned a Wyred4Sound STI-500. My speakers are power loving Usher BE-718 monitors similar to your speakers. The NAD is (for me) much more satisfying for my taste and system synergy. It also has the outstanding feature of a variable high pass filter on one set of pre-outs so I can integrate my pair of subwoofers with the Ushers. If you currently do or plan to use a sub in the future this feature is pretty unique and absolutely effective.

Now I can fully crank electronica like Underworld or Crystal Method and the Usher woofers don't look like they're going to fly out of their frames while the pair of JL subs get to have a field day and go crazy. Really refined too on folk, jazz , classical, and most everything.

The W4S more extroverted-wider and deeper soundstage, more upfront detail across the freq spectrum, and outstanding separation of instruments. Just phenomenal with the right recordings. Unfortunately with the Ushers it was beamy, metallic, and uncomfortable sometimes as well. The M3 is meatier overall, much more forgiving of bad recordings, never quite phenomenal but always really good and doesn't leave me wanting. The other nice thing about the M3 is that the louder you play it the better it sounds. It gets fuller and stronger without getting more forward.

I haven't heard your speakers but if they are laid back the W4S is a great recommendation. If they are a bit forward the M3 is a good alternative. They both have high-quality stepped attenuators which I have convinced myself is a great feature. That's my two cents' worth after I read the good recommendations above.
