OPA604, OP134, NE5532, TL071, AD827 are good opamps; However those are not top of the range if compare to AD797; Have you ever think to replace them by AD797?
The AD797 is a very low noise, low distortion operational amplifier ideal for use as a preamplifier. The low noise of 0.9 nV/ Hz and low total harmonic distortion of 120 dB at audio bandwidths give the AD797 the wide dynamic range necessary for preamps in microphones and mixing consoles.Furthermore, the AD797 s excellent slew rate of 20 V/ s and 110 MHz gain bandwidth make it highly suitable for low fre-quency ultrasound applications.The AD797 is also useful in IR and Sonar Imaging applicationswhere the widest dynamic range is necessary. The low distor-tion and 16-bit settling time of the AD797 make it ideal for buffering the inputs to ADCs or the outputs of high resolu-tion DACs especially when they are used in critical applications such as seismic detection and spectrum analyzers. Key features such as a 50 mA output current drive and the specified power supply voltage range of 5 to 15 volts make the AD797 an excellent general purpose amplifier.
