what amplification are you running with your Dynaudio Heritage Specials?

I use a Supernait 2 mostly and a Willsenton R8 for winter.  

I have to agree with @cbrez the HS don’t need high wattage, but they are a speaker that can scale up to its amplification. More then any other speaker I’ve tried, they do a great job revealing the subtle characteristics of it’s amplification. With my tube amp I noticed it sounds better with 25 watts triode then 45 watts ultra-linear so it’s definitely not about the watt count. Room size also matters, I have mine in a medium sized room and think they’re perfect. Of the YouTube videos I’ve seen, not that this is an accurate way to judge, but I was really impressed by the Gryphon/HS combo. That’s going to be on my list of things to try one day. That and the INT250. I also heard them paired with a Hegel 590 and I’ve never heard the Hegel sound better. So that’s another brand worth trying. We are kinda talking amongst ourselves however as OP has moved on from the Heritage.

It all depends on the room and listening volume, but I wouldn't use the term overkill by any means.  I'd love to see Nelson update their integrated range, and yes to more black models with that blue dial.
