I have not heard the Doshi however, I have heard many people whom I respect say that the Doshi stuff is excellent. 

The biggest issue is that a company like Doshi has very few dealers throughout the country so they are hard to demo.

Other great salwarts like ARC and CJ might also interest you.

We have a demo pair of CJ Art amplifiers which use 6650 or KT 120 which are punchy tubes with great bass.

The  EL 34 tube is known for musicallity rather than bass omph so it will also depend on how you want to use your system. 

If you are new to tube amplifiers PM us we have a lot of experience with many different brands and can give you a low down on what you might want to expect.

I've never read anything that was less then positive when it comes to Doshi, so I imagine the Johr's are very nice amps.

Are you specifically looking for an amp with EL34 output tubes?  Or any specific reason you are considering the Doshi's?
Doshi Johr is voiced for Wilson Sasha's and bit on dark side so IMO not best match for SF.   For tube amps, checkout ARC.
