and thier is a huge difference between the models IMO
The 801D is a tank,the thing can run all day long,never gets hot and is very heavy duty
but.....
The xenon has better SQ,is less durable IMO
Xenons track record stinks , mine broke in 5 days - sure they replaced it but I havent used the replacment model yet - I am uncertain if I should bother with it or Ebay it off
If you go with the 801D I am pretty sure youll have an easy time of it
if you grab the Xenon your rolling the dice so make sure you get a warrenty
