Got My Gator board in a T7520 with an AD826 opamp + Caiman psu , hadn't tried the passive mod due to needing volume control, had tried cutting the MLC5 & 6's but after initial extra detial lovelyness ,was far too harsh so reconnected.
Also put in LM4562NA's and liked what I'd heard.

All I can sat now is WOW, extra bass definition , a more 'realistic sound' to instruments and voices,silky smooth with fantastic detail and a more open soundstage. I've only had about 30 or so hours through the board so will probaly try the LM4562NA opamp in about a week , by then I should have put around 100 hours into it.



If anyone has a T7520 I can honestly recommend the £50 ish upgrade, I'd love to hear what a Caiman sounds like with this in if it can make mine sound this good .

Just wondering what opamp you are all using ?

Cheers
Paul
