I have a fully modified Caiman that I may consider selling.
The Caiman has been upgraded with a Wolfson DAC, Nichicon bipolar Muse Capacitors, Wima & Elna Capacitors, and Murata Power Voltage regulators. I also have a different opamps for it including the LM4562HA, TH4032 and AD826. It's a pretty expensive upgrade but the results are out of this world.
The Caiman has about 20 hours on it. I will be ordering a Wyred for Sound DAC-2 today because I now need a balanced DAC to take full advantage of my WOO Audio 22 amp.
I may keep the Caiman but if you offer me the right price, I could consider letting it go. I can certainly email you pictures as well
If you aren't familiar with all the mods they've been discussed here:

Tirna Electronics charges about $135 Euro's for all these upgrades (not including the LM4562HA, the TH4032 and the Wolfson DAC)
