If you think it is worth the extra effort (which quite frankly I don't), the next version is interesting. The open loop gain of this configuration is now an astonishing 1,200,000 - or over 120dB from a single amplifying transistor. The op-amp acts as a unity gain buffer - basically a "high tech" version of the emitter follower in the previous circuit.
Although open loop gain, as well as output impedance and output drive capability are all improved, the noise figure can be expected to be slightly worse. It is also likely that although measurable distortion may be reduced, the preamp may lack musicality - that undefinable something that no-one has actually been able to quantify. IMHO this is very unlikely with this circuit, but one never knows.
Gain with the values shown remains at 32dB, and the op-amp should be powered from the +30V and 0V rails (i.e. NOT with a split supply - the voltage will be too high for the op-amp). The second version has not actually been built and used in earnest, but has been simulated and is a viable proposition - it can be expected to work as described without problems.
This is the figure:
