Audiophile dj mixer - does such a thing exist

I have already made a post about upgrading my hifi setup.  I also want to include a dj mixer in the setup.  There are many dj mixers out there ranging from the cheap and cheerful to the pricy.

I am looking for one with the best sound quality.  This is far more important than features to me as I am not involved in beatmixing or scratching.  I produce radio shows so really just need a straightforward mixer with 2-4 channels and excellent sound quality.

Some of the models I have been considering include

HI-LEVEL PM4000-19  http://www.hi-level.de/english.htm

TL Audio Fat Fiddler DJ mixer http://www.fat-man.co.uk/docs/product/fatfiddler_1.htm

Allen & Heath Xone 92 http://www.allen-heath.com

 So far I'm leaning towards the hi-level offering as the emphasis seems to be on sound quality over dj gadgets.

 My other option is go for a broadcast type console such as the D&R Airmate

Any advice or other suggestions would be welcomed.
