Thanks for the comments, guys.
@hsw ,the I50 is on my radar, too. Are you in the US? Bluebird doesn’t have the KT150 integrateds listed on its site, which made me wonder whether they are available here.
If I may ask, how are the noise floor and treble extension in the I50? How did it compare to the I88? What speakers are you using?
@jjss49 , the brand seems to be experiencing something of a revival, with some new models and updated versions of older ones. I wasn’t aware of issues with Bluebird. I’ll have to dig into that.
