i have now had a mere two days of using the burson v5i

it replaced a dual opa627 in the buffer position on my asus xonar hdav1.3, that was initially occupied by the stock supplied (LM)4562NA

having decided in short order that the opa627 was an improvement on the 4562na i never changed it out in half a decade because it seemed clear to me that opa627 was better at “tight” bass and general all round reproduction

until wednesday afternoon… when i discovered how the burson v5i compares

in a word : better
in more words : n(much) better
