BURR BROWN OPA627 AOP Double (deux simples) sur Support (Unité)

Perfect for ROTEL RC-971
Superb sound for my Rotel Rc-971 preamp (Volume control OP).

Great improvement on Fosi ZA3
I have purchased these op amp to replace the stock op amps on my Fosi ZA3 and ZD3. These greatly improved the sound quality of ZA3. For ZD3 stock op amps, LME49720 sounds better than Dual OP627.

Perfect Opamp
Clearly hearable difference with AUNE default Opamp. Very smooth and detailed sound

Belle surprise
Le son est détendu et bien contrôlé avec une séparation légèrement prononcée des voix et des instruments. Écoute en finesse.
Bien meilleur que les NE5532.
Je pense acquérir une paire de Opa2604ap pour comparer

Hungary
The point is, I think it was worth it. Its sound is almost creamy, it packs the instruments into the space better + I feel it is a little more detailed, more listenable (analog), more lovable in the long run. Of course, this is just my opinion. I made a loose video, unfortunately, due to the high compression, the difference doesn't come out as much as in reality, but once I've "worked" with it (rather played it), I'll share it. .., have fun with it: https://youtu. on/sZKlYxdNpoo
