Caiman passive output mod revealed

Nice! I'm sure some will be interested in giving this a go, its reversible incase you prefer it with the output op-amps.
I'll have a scrounge to see what caps I have

I'll stick the link to this thread in the collection of mods

Cheers Leo.
I wanted to add a 100nF cap across the 47uF in order to bring up any attenuated highs from variations in HF damping from the 47uF. But because the mod has no HF roll off filter in circuit, I decided to let the 47uF act as a bare bone HF filter without the 100nF. Others might disagree with that approach, so I mention it in case anyone wishes to try the 100nF in parallel with the 47uF.

Important addition!
The fixed output signal from the RCA sockets should be plugged into an AUX input on your amp. That's because the passive mod has a lower output by about 3dB compared to the opamp boosted output. You can use the signal in the CD input, but you'll have to turn your amp a bit higher in order to get the same average level as obtainable with the opamp in circuit.
