Ayre KX-R or PS Audio BHK Pre


Hi 
I have an chance to buy either of the above 2 pre amps. Price is not a problem as I am getting a great deal on the Ayre as a demo unit. Still the Ayre is a bit more expensive but I can live with the price difference. What would you guys recommend. Associated equipment is as follows. 
Power Amps Classe CT-M 600
Speakers B&W 800d
Current pre Mark Levinson No. 38s
PS Audio Direct Stream Junior
Clearaudio TT with Avid Phono
Music tastes are mostly Classic rock with some Jazz thrown in.

How could you not jump at the Ayre..  I'd also send it to Ayre and have it upgraded...they do a wonderful job.
Thanks for the input guys. I feel an update is needed from my side. 
I am not based in the US. The Ayre unit is with my dealer and the PS Audio unit would have to be imported. So having an in house demo is not possible. Our mkt is really small and the dealer does not have any "demo" units. The particular Ayre unit I am looking at is basically brand new, just opened to see everything works. It carries a full factory warranty. 
The only way for our small Audio community to buy stuff is based on reviews and input from fellow enthusiast like you. From what I am able to understand is that while the PS Audio unit is excellent and would compete well with any pre twice its price, the Ayre is on another level. I am thinking if I get the price I want I will step into the Ayre and hope for the best. 
Hello srafi, 
 I can understand your dilemma given your logistics.  The Ayre is accessible  (your local dealer) and THE BHK isn't. Ayre has a longstanding reputation and very loyal customers.  It isn't a reach to decide in favor of the Ayre for these reasons. It's a safe choice. 

I however wouldn't make the assumption the Ayre is on a different level, that is only determined from actually listening to both components.  The BHK has excellent reviews and owners feedback.  Very likely it has a different sonic character given its implementation of tubes.

I don't doubt that the Ayre could make you feel very content.  Its certainly possible the BHK could do the same or perhaps even more so.  You just don't honestly know without hearing them.

The OP has a problem that many of us in audio emporium wasteland suffer from;  no where to audition components.  We are reduced to relying on professional reviews, manufacturer reputation, and what we read from users here.  Audiogon is an important resource for those in our predicament.  As you involve yourself here over time, you begin to identify others who seem to share your audio preferences and thus use their postings to help inform your component/accessory purchases.
