BURR BROWN OPA627 Dual OPA with Support (Unit)

Massive improvement pver original Opamps in Aiyima T20
OMG - these dual OpAmps were a massive improvement over the original Opamps installled by the OEM in my Aiyima T20 elevating the performance way above the price bracket. The combination of these 3 OpAmps and NOS tubes make the T20 a serious tubed preamplifier for ridiculously little money (in the serious HiFi realm).

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
