OPA627X2 turn dual op amp finished ( Germany WBT-0820 silver soldering ) For hifi amplifier A3-013
Great op amp, excellent workmanship, solder well built, hight quality. Did the exchange my opa2604 FOR THE opa627 quality rose to another level, congratulations
Good!Not original or not, but with xDuoo XD-05 sings well.Resistance between 1-5 feet chip ~ 47 COM and ~ 50 com. The chip look like the 3rd photo: engraving, and white bright paint.
Order came quickly, work, no noise, but in comparison with OPA627SM (metal), that I have are in sound card Asus Xonar Essence STX, significantly worse (scene, detailing the lost, and T. d., listen to music through them not interesting) It's probably not fake. Maybe they are better, OH устанавлеваемых in sound card by default, but too lazy to compare.Recommend if you can use OPA627SM (metal), the sound card Asus Xonar Essence STX, it is natural, transparent clear, nice sound. Listening to headphones sennheiser HD 600.

Description
OPA627X2 turn dual op amp finished WBT-0820 silver soldering)
Finished containing 2pcs 627 can be directly substituted NE5532,2604 op amp as an upgrade, this is BB\'s most high-end operational amplifier, low elongation are very good
Welding We have chosen IC paired with batch numbers before soldering, do not worry about any imbalance
The most basic way to identify German WBT-0820 silver tin: Very shiny solder joints far more Senju
BB company amplifier recent soaring costs but also had no way to improve it
The IC has a white and laser two kinds, white is produced in Malaysia, the laser is Taiwan, Taiwan is also white, and the bottom is the same as TWN laser tag.
Because the internal circuit is the same, so it is also consistent physical characteristics, such as the operating current was relatively large, the work came from than 5532, OPA275 to heat, another measure this IC with a multimeter, the resistance of the pin, and black and white is the basic laser consistent.
Top op amp OPA627: BB\'s is by far the most upscale OPA627 operational amplifier, also using FET input, sound warm and inviting, but its price is really scary, to use such expensive op amp, if able to achieve this performance prices are a matter of opinion, but heard the fans OPA627 are agreed that the AD827, LT1057, etc. simply can not match
