Krell KAV300cd Vs. Wadia 830

Has anyone compared the two of these? And how do the Resolution Audio CD50 and 55 compare?
I have owned the KAV 300cd the resolution cd50 and currently have the cd55(just sold on audiogon) The resolutions are much better than the KAV, IMO. The resolution products are much more musical.The 55 is an improvement over the 50. I have heard the Wadia's but they have never been to my taste.
I have had a KAV300 in my system for a brief period of time as well as an Wadia 830, 850 and an 860x which I currently own. The KAV300 was by far my least favorite.
