Mike, op amps for that purpose should be available from a lot of companies. They are not created all equal. My latest own design of a distribution amp involves one AD8007 input stage with variable gain and 8 AD8007 output stages. This design is good for a channel to channel isolation of 90 dB and an output to input isolation of 113 dB. The AD8007 has VERY small distortion and I needed to build a lowpass/bandpass filter to measure it because NONE of my sources (HP3325/HP8660) was clean enough that it could match the AD8007. The -125 dBm noise floor of my sprectrum analyser were just enough to see any amplifier produced noise. The power supply design may be as important as the choice of amplifier.
