My apologies for being off topic , I have a modded Akitika G-102 paired with a Rogue RP-1. The combo of a tube pre and the ability to roll gives me a considerable latitude in regards to tone. I’ve powered Klipsch Heresys and Zu Omens with great results. I wonder how a tube DAC might fit your need. I’ve not played with your speakers but I see a lot of crossover mods done. Happy Listening, Mike B.

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
