op amp rolling

I have a setup for a send system that I have been playing with to see what I can do on the cheap and I've been quite surprised at the result so far. I've been reading about supposedly major improvements in performance of the Fosi ZA3 amps with op amp swaps. I'm wondering if anyone else has had any experience with the various ones available. I'm running the dual mono with XLR on each speaker bi wired to max the power which means I'll need three per amp which will cost more than the amps so I'd like to get it right the first time if I can. I'd like to take some of the sibilance from the top end which some I reckon comes from the nature of the speakers (Klipsch RPM 600II). Any opinions/advice would be most welcome. I'm looking at the Burson v7 vivid and the sparko but the sparko has been reported as softening the ZA3 too much which the reviewers on youtube seem to like for the V3 mono but not for the ZA3. I have attached a link to the setup because I cand figure out how to attach the photo to this forum. Thanks in advance

I've done fair share of op amp rolling. Staccato op amps are my personal favorites, but I do think sparkos are also quite excellent (and way more accessible). 

 

Sparkos have a sound that is very fast and vivid which might not be great for your Klipsch speakers. I think you would be best served with staccato, or possibly Orange op-amps (though I haven't personally heard those myself).
