Sony - SRS-X55

Denon envaya 150/200/250, Sony srs x55, x77, Harman Kardon Onyx 3,4, Xiaomi Sound Move, Créative Sound Blaster Road 2, Marshall Stockwell, Marshall Emberton 2, Harman Kardon Go + play (the one from 2016), Riva S, Riva Festival, Bose SoundLink Max, Bogasing S8 Pro Max, soundcore x600, Doss soundbox XL, Jambox, Sony srs xb33. I made "widest immersive stéréo imaging soundstage" one of my first point when i buy a speaker, and i like to try the most possible. they have all différents sizes, from différents years ,but all of them have insane soundstage with great stéréo separation for the size. Seems that older bluetooths speakers was better on point than recents ones (except for somes).

that sony x55 was real nice but a modern equivalent of that would be the bogasing s8 pro max. try it. its the nicest speaker nobody talks about 🤫

The best I’ve had is the Sony SRS-X5. But I should also admit I haven’t needed to shop for Bluetooth speakers since I’ve bought it 8+ years ago, so I have no idea really. I do have a UE Roll and a JBL Go and Go 2, but they aren’t comparable. They are in a different class altogether.

ULT1,3 and 5 is the least bad of the srs XB series (but ult lacks descent bass vs jbl, bose and soundcore on default and boosted settings) ULT mode kills horribly the mids and harsh the highs on the ult series. Miss SONY audio pathway from srs x55,x77 and x88 series on 2015 and 2016 in wich were suprisingly very good sounding portable indoor speakers, miss their tune and very well shaped non boosted midbass of that era. At least their new 2025 bookshelf speakers has the sound style I used to, in their 2014 to 2016 line-up. Bluetooth speakers that were impressive for their tune and size on nwe models of other brands are (for me) bose flex gen 2, anker soundcore 300 and Harman kardon Luna. Actually I use a ruark r2 mk4 audio compact systems that makes me feel like I hear those old sony hi res systems of 10 years age but with new connections and functions.
