Tube Power Amp Suggestions


I have been looking for a tube power amp. Ideally I want to have about 40 to 70 watts output power, with sound qualities as close to a delicate SET amp as possible, with lots of details, fast, good tone (a tiny bit on the warm side) and imaging, yet with good bass and dynamic. Budget is about 10,000. Second-hand is fine. I know I am asking really too much and will probably get negative response because of this. I just want to get the best within my budget.    
      
My initial considerations are EAR 890 or EAR 861. What do you think?      
    
I heard people saying that push-pull amp can be better than SET if it is implemented well, but push-pull is more difficult to make than a SET amp.    
      
My speakers are measured 91db sensitivity, but it needs power to perform well. I have tried both a SET 300B XLS output at 13W and a push-pull EL34 at about 35W. My impression is as follow:            
      
- SET 300B XLS output at 13W: more delicate and smooth, better resolution and density, lack bass and dynamic       
- Push-pull EL34 at 35W: much more bass and dynamic, sounds a bit coarse, less 3-dimensional and delicate     
    
Thank you in advance for your input.

Charles is right about an 845 SET amp. That or parallel single ended 300b amps. 
Many thanks again for all your kind recommendations. I will try to have audition on as many of these amplifiers as possible.   
    

Bill (Grannyring),
I mentioned the Zero transformers based on their "theoretical " potential benefit. I’ve read comments from other users who had the same experience as you regarding the Zeroes. They did adversely affect the sound quality. I’m confident that a well built and implemented amplifier using 845, 805, 211 or the Russian 6c33c used as SET or PSET with 4 ohms taps will pair well with these speakers. The essential key is high quality power supply and output transformer as previously discussed . A few examples are  the Line Magnetic 219ia, 508ia or the Coincident turbo 845, also a used Viva Solista 845 SET. All of these are well within the stated price range.

Of course there are very viable options for push pull amplifiers, it really depends on the type of sound character Bigdish is seeking. He has a variety of good pathways to pursue.
