Jerome...I have 3 different avenues of advice:
#1: Stay away from reading AA for the next 2-4 weeks, or if you can't do that, just make sure to not read anySHindo-related threads, or anything that Serge, Alberto, Jayson (adhesiv), and Scott (sibelius) post because there is likely something Shindo-related there
. After this "cool down period," (this is like taking a cold shower...) you can see if you still have the "hots" for Shindo (somehow I don't think you are going to do this and if you do it's not going to work
)
#2: As Howie says, if you are not worried about the financial hit, buy the CCQ and if it does not match up well with the EB1is, then you can resell it (hopefully for a minimal loss). As others have said, the odds are likley it will not be a great match (not in terms of being able to drive the EB1is to healthy SPLs but in terms of tonal balance, which is the issue you had with the Verdier in the midrange with female vocals) but you will never know until you try it.
#3: Audition the Burmester and Ref 5 in your system (both should be locally available for auditions I assume) and decide which one gives you more of a different flavor in your system. My sense is you will get more of a shift with the Burmester (as compared to your 2301s), vs. the difference between the C1000P and the Ref 5. Also, Randy's suggestion of using the Burmerster in the summer and the MC2301s in the winter, I thought was a great idea.
I know there is not much new here in terms of suggestions but that's the way I see it. I really do thing if you want to go Shindo, it makes more sense to do a complete system change by starting with new speakers and then building the Shindo chain for it.
Good luck.
