Suggestions on a neutral and powerful integrated..


I have gone through quite a bit and just looking for some feedback from others.
I am looking for a neutral sounding but extremely powerful integrated amplifier for a pair of Wilson mk3 (I am aware of the specifications and I do require power and control at loud volumes)
Please do not suggest anything out of my needs since I am specific in this requirement.

I am currently trying a hand full of integrated's but truly would appreciate some input based on your experiences.
I have 7k to spend (new or used and leaning towards used for the available choices) and need a single box solution. I have tried all the Krell's, ARC, Ayre, Pass, Audio Note integrated units and now I am wanting to move a notch up.
Thanks

Sorry about that, I don’t know why the link isn’t working. It’s an Audiogon listing for a NEODIO NR 600 SIGNATURE Integrated amplifier.
There is definitely some good suggestions and thanks. I am looking at the DartZeel 8550 and Boulder 865 and even considering the ARC DSI200 since I have access to one.
