I received the Expanse today. My test tracks reflect the music I listen to most often:
--Cleveland Orchestra, Krenek, Static and Ecstatic: perfect tone and separation (I also heard this actual performance live).
--Dave Brubeck, Take Five: Bass drum 3 dimensional, other instruments warm, precise, smooth. ( I heard this performed live 45 years ago).
--Chicago Symphony, Bartok, Music for Strings, Percussion, Celesta: Ethereal, spiritual, surround 3D. (I have heard this performed live by Cleveland Orchestra).
--Horowitz, Horowitz in Moscow: Dancing precise fingers, absolute perfect tone and breadth of tone.
--Nina Simone, I Love You Porky, Live Carnegie Hall: Deep, rich, like she was singing 10 feet in front of me with tears flowing down her cheeks.
--Alison Krauss, I've Got That Old Feeling: Crisp, precise yet gentle.
Equipment: iFi iDSD Signature, iFi iCAN Signature
I am usually confused and do not understand many of the reviews due to the technical nature of them. My experience is emotional and my experience is limited by the other HP I own--800s and HE1000v2. I consider the Expanse to be the culmination of the two. I am glad to own them and would gladly purchase again.
