I just ordered a new SE84UFO2.  This is my first tube amp.  I know it depends on my setup but I was wondering how much of an improvement adding a DHC1 power cable will make to the sound of this amp? Has any one switched between a stock cable and a DHC1 on their Super Zen?

My configuration will be the following:
Bluesound Vault (Hi Rez music server), Audioquest Kink Cobra interconnects, SE84 amp, Audioquest type 4 speaker cables, Monitor Audio Silver 5i speakers (89db)  I currently use a fairly cheep Pyle PCO 850 power conditioner.  

I would consider upgrading cables an upgrade the speakers next year to some that are more efficient.  

So I would like to know what others think about using the stock cord, or the DHC1, and would a better power conditioner make much of a difference?

It seems you have lived with your SE84UFO2 for a while. How do you like it? Knowing what you know now, would you purchase it again?

I'm sorry for not responding sooner to these posts.  I have been active in the forum but have not looked back at this post.

I love the UFO2.  It plays plenty loud enough in my room.  It has amazing detail, sound stage, and imaging.  I would definitely buy it again.  Since my original post I replaced my speakers with DIY OB's using Wild Burro Audio Betsy drivers.  For a very small investment I have a system that IMO sounds like it should cost 3 to 5x more.

I really like my Bluesound Vault from a hardware perspective.  It's a really nice one box solution for storing and playing digital music.  The sound quality of the Vault is better then my Marantz CD player.  Bluesound has recently made a major upgrade to the software and user interface.  I actually liked the old version better from a user interface perspective.  Since I first posted I added a Schiit Bifrost Multibit Dac which was a big improvement over the Vaults Dac.

Donzi, you should check out Bluesounds user forum at:
helpdesk.bluesound.com/discussions

There is a lot of discussion on the software upgrade.  If you have a dealer near you you should check it out in person before buying.
