Absolutely. It really sounds gorgeous. Prior to the Sony I had used much smaller, more portable amps (Mojo, Micro iDSD, Hifi M8), all of which actually drove the LCD-3’s satisfactorily (I listen to mainly classical orchestral music), but there’s now a much greater sense of “ease”, unrestricted dynamics, and limitless headroom with the Sony.
I found my Chord Mojo drives my Focal Utopia's ok 'ish ... but put them on the Sony and they are much more alive. I only use the Mojo now with my Clears and the Utopia's sit plugged in permanently to the Sony amp ... for more needy headphones a more powerful amp does seem to make the difference.
