May 19, 2019 · The 4558 input amplifier and the buffer of the same type had to make room for industry stalwart NE5532. All opamps in the deck obtained a 100nF film capacitor between their supply pins. This is a practice advocated by Douglas Self in his books and articles, after he observed how some opamps outright demand this.
upgrade takes only 15 minutes, and gives a dramatic improvement in resolution and clarity, even if it's only a midrange CD player. Circuit stability. This OPAMP is stable even with very poor decoupling. However should you wish to add local decoupling caps, you can place them under the motherboard. We recommend 0.33uF Mylar types, like This one..
With my new Dual Stack Adapter and two NE5532 opamps I have finally eliminated this known issue with the BD-2. In my testing I tried a number of opamp combinations and two NE5532s sounds the best and was the only combination that eliminated the unnatural decay of the BD-2. The two NE5532 opamps now give a more natural sounding overdrive.
