The XLR was in the end recommended the OPA1656, since the signal passes the Oracle´s anyway. Initial impression is very satisfactory, the background is dead quiet. Joined 2018. Many of the modern class D "chip amps" have socketed op amp The advantage of OPA1656 is that it has JFET inputs rather than bipolar, so its input bias current is much lower, making it easier to keep the output DC offset low in some applications. This video title is; 2Which OpAmp is Better for 20W Class A Amplifier - OPA2604 vs NE553 Technically speaking, it's really hard to beat opamps like AD797, AD8599, OPA1612, OPA1656, so it might be safer to use one of these over the "exotic" ones, unless swapping opamps is really fun for you and you have enough money to spend on this hobby. - Piano: The percussion of the hammers hitting the strings was more realistically portrayed, and a slight edge heard with the LT1028's went away when using the Sparkos SS3601's.
