Jungson or DK Design: good with Quad 989's?

HI--I run Quad 989's currently driven by an ARC D-400 solid state amp. Although this set up sounds overall very 'nice', I am looking for more dynamics. I really value midrange presence and body and would like to avoid tube output stages. I would also like to move to an integrated.

I'm intrigued by the buzz on both the Jungson 88D and the DK Design integrateds. Here is my reasoning on mating with the Quads: The Jungson is Class A which I understand is good for electrostats, it's sound has been called tube-like, and is rated at 80w/ch into 8ohms which MAY be enough drive. The DK is 150w/ch into 8 ohms and advertises "a massive output amplifier capable of driving any load..." It is not class A but it does have a tube front end which may offer the midrange I'm looking for, and some ability to tailor the sound using different tubes.

So....Please offer me some informed opinions (or better yet experience!) regarding how well either of these might mate with the 989's. Or, if you have suggestions for another integrated that you have heard making wonderful with the Quads 989/988/63, please advise. --Thanks Much!!
