Wadia, Audio Aero, Meridian, BAT and BOW

Hi,

i have a Wadia 860 and was considering upgrading to the Wadia 861.

But i could also sell the 860 and buy either the Meridian 588, BAT Vk-D5 SE, the Audio Aero Capitole CDP or the BOW Wizard.

I was wondering if anyone could comment on the above players, and say which ones they would prefer and why.

Cheers
Xav
