mono block or bi-amps which would you pick?

Just want to say thanks for all the inputs from Audiogon members.  
 
I want to keep you all posted.  I decided to buy the Zanden 9500 mono block, 845 triode output/push & pull design.   The amp gets around 50watts pure class A.  To mate with that i bought a Zanden 3000 tube preamp.    I will see how it goes.   Happy Listening! 

Great move, zipost, let us know how it turns out.

Zipost, I've been tossing around the idea of the Zandens for a while now. 
Curious to hear how your system comes out, particularly the bass. The Zandens have the rep of being very smooth. 

Yes, zipost, let us know how you fared.

Zanden is not smooth. It’s delicate when need be, and slam a home run when it should.
