Default BJT line buffer

Hi,
I thought i would contribute with my suggestion for a line buffer which at least according to simulation, yes i know don't trust it, looks good.
I was searching for a bipolar line buffer to use as a buffer for a CD player which was inexpensive to build and fit into the CD player without a new PSU.

The CD player had a +-10v PSU for the OP.

According to Kuei the only way to get the DAC, PCM 1716, i have to sound good is to couple it directly from the vout, via a DC blocking cap, to the preamp.

The DAC can take a 5k load but i thought i would create a buffer and buffer the DAC output, this would also enable me to load the DAC with a CCS to bias it into class A.

The design is taken from here and there and i had previous versions which included CFP's on the outputs but those were discarded since i couldn't get the distortion down enough, simulation problems?
