Jul 12, 2004 · Another listen. Well, listened again last night to AD8610 (unbiased) vs OPA627 (biased into Class A, 2mA, with a JFET) and there is a difference. The AD8610 seems to present a more open window, especially in the highs, on music, transients and realism of highs being enhanced. I would say though that on some CD's it can come across as a bit bright.. "/> Opa627 vs opa1612 vba sort column

The 627's will exceed the technical specifications but sound is very subjective. Maybe it will be better, maybe worse, but likely, you will not be able to notice a difference.

Jul 29, 2020 · The OPA627's presentation isn't quite as vivid as the the stock OPA1612, but it doesn't lose much.

OPA627 were quite popular in the late 1990's through 2000's for high-resolution audio. The key attributes that made it popular were its ultra-high-input impedance due to J-FET input (meaning it sounded consistent regardless of input source), and high gain-bandwidth product. The OPA627 creates a flat soundstage that stretches further to the left and right, but all quite close to the listener. The V5i has an equally intimate sound (close to the listener), but it's shaped like a triangle with the sounds at the centre closest to the listener and then sounds to each side drifting further away.

Not sonically different of course but good performers and can actually run on +/-24V (in case one needs opamps to go slightly above the usual +/- 18V rails) When rolling opamps having a 1GHz scope could come in handy.. The OPA1641 would be a good alternative for the OPA627 in the servo, or for that matter, in the signal path. OPA827 is also a great op amp for the signal path. In my opinion, better than the OPA627 but it has not yet earned its stripes in the audio community. Neither of these newer op amps is available in DIP package which may be a consideration.
