Well, I've tried them w/ LT1363CS8 and it made them bass shy and utterly bright...I think the commercial bs on his ebay page dissing the genuine Browndogs is completely unfounded...Also, the presoldered pads hardly stick w/ Cardas eutectic solder...these adapters have disgusted me of soldering opamps tbh. And it's also quite annoying to solder the adapter pins, even though I also do it on the real browndogs now for improved contact as it made a clear audible improvement on LT1363CS8 for me(clearer center channel).
BTW, you never told me what you honesty thought of LT1363CS8? But I'll try AD797BR on a real browndog anytime soon, I'm starting to realize that most cheapo adapters from ebay end up being bass shy...for some reason.
I really don't like ADA4627-1A(never been a fan of the OPA_27 sound) and LT1028AC is too pesky, I give up...1363 sounds perfect to my ears anyway
