I have a Highly modified Caiman that I am selling.
The Caiman has been upgraded with a Wolfson DAC, Nichicon bipolar Muse Capacitors, Wima & Elna Capacitors, and Murata PowerVoltage regulators. I also have installed different opamps including the LM4562HA & TH4032. It's a pretty expensive upgrade but the results are out of this world.
The Caiman has about 50 hours on it.
If you aren't familiar with all the mods they've been discussed...
