That's always a compromise between worst-case output impedance (lower for lower values) and things like channel imbalance (usually better for higher values, for whatever reason). I think I used a NE5532 in my KOT. 18nV/rtHz vs 5nV/rtHz makes the NE5532 much quieter for most applications methinks the OPA1612 cannot be beat---the combination of low noise, low THD, high common-mode/power supply rejection, fast slew rate, and rail-to-rail operation is simply the BEST. (TI NE5532) wih an OPA2107 and notice a significant improvement. Pretty much a stock board with Some will point out the OPA1612 (which is even better) or the OPA1656. But to take advantage of this, you need to ensure that the Johnson noise of the resistor network you are feeding the input from is small, which for If I could also request test of: OPA1642 ~ 2 Euro OPA1656 ~ 2. I'd suggest using NE5532 or OPA1612 for U4 in the first instance and see if that's making a difference. They sounded better in all applications so they are a worthy replacement. A I popped the hood on my Aiyima A07 and I must say I'm impressed. Like so many things in audio, how the device is used in a given circuit is a huge variable, and will undoubtedly have an impact on sound, so swapping op amps isn't as simple as just AMB Laboratories DIY Audio Forums. vorondesign. If the NE5532 improved its HF performance it would sound the best of all these by a reasonable margin . It is using the same chips as the Soncoz SGD1 ) At first sight, the DAC is really really well made with quality components I'd use an OP275 instead of a NE5532, it's better sounding (sweeter) and has no dc offset to contend with 1to5mv, so can be direct coupled, unlike the NE5532 which i've seen sometimes at 400mv, and the OP275 can be cheaper, sometimes. if the gain is going to be x1 then you would need a unity gain stable op amp. Each one covers one NE5532 and one OPA1612, meaning, each heat sink covers 2 different op-amps. Ti datasheet for the PCM1794 makes use of NE5534 and I must admit that I was impressed with the PCM1794 using just Ti NE5532 before I obtained the OPA1612. Tom It seems to me that the selection of what op amp to use depends greatly on the circuit they are in as well.
