Tried a WT-550/D410XLT and an XS800h/XC808 cabinet. Apples and oranges here! The Eden was clearer and more 'nasal'. Nice tone! Some white noise past '6' on the volume dial with the EQ flat and the gain at 1/3, even with the tweeter on the cab off. This bugs me. An amp this expensive should be dead quiet, right? The Yorkville was louder, growlier and more ballsy, but a little bit darker. Quieter than the Eden with respect to noise as well. Go figure: I expected the opposite. It's a bit heavier and bulkier than the Eden, but still only weighs half as much as my rack. The XS800h seems like a much better deal than the Eden, as first impressions of the Eden rig left me underwhelmed. They are only first impressions though. If a new preamp tube opens up the sound of the Yorkville a bit, then this could be my next amp.
