mono block or bi-amps which would you pick?

I have two choices on amps!    

I am thinking either getting a Zanden 9500 mono block at 60watts push pull 845  triode per side

or

getting a Viva Verona xl mono block single ended using 845 output tubes at 28watts per side.  

Do you all think this will be enough power to run the Odeon Speakers.   What's your thoughts?? 

Assuming the speaker specs are accurate, which can often be a big "if," and assuming about 3 db of "room gain," it can be calculated that 28 watts into each of the two speakers will produce an SPL of about 106 db for a centered listener sitting 10 feet from the speakers. 60 watts would produce about 3 db more than that.

Either number is more than enough volume for most listeners on most recordings. Exceptions are likeliest to occur on material having extremely wide dynamic range (i.e., a particularly wide difference in volume between the highest volume and lowest volume notes on the recording, such as some large scale classical symphonic recordings that have been well engineered with minimal or no dynamic compression), or if you routinely listen at the levels that are often encountered at live rock concerts.

Al... thanks for the inside tips.   Really appreciated! 

If money is no object then have a custom designer make you a pair of amps.  Something like point-to-point wiring, custom transformer, copper chassis, better resistors and capacitors, etc.

Mono blocks as custom designs would be heavy.

Happy Listening.
