This Caiman SEG has the Super-cap and Super-clock upgrades by Stanley Beresford with the SEG 3.0 firmware.  It comes with the Dorado (Mk I) Supercapacitor power supply upgrade (the 15V setting makes a real difference) and DC cable. 

The SEG has USB, S/PDIF optical and coaxial inputs and RCA outputs.  The selector on the front panel allows it to be used as a pure DAC or a pre-amp.

The upgrades included:

• SEG-30 firmware
  
• Supercap upgrade of the 5V and 3.3V digital power line inside the DAC
  
• Temperature controlled low jitter CMOS clock upgrade
  
• Darlington pair transistor upgrade of the active noise filter in the incoming DC supply.
  

You will need a power supply to feed the Dorado (I used a battery with 16V output), which takes a short while to charge on first use or after being switch off for a few days.

Used together, the sound quality is very good.

I have had both from new and they are in excellent condition and fully working.  There is a scratch on the underside of the SEG.

A new SEG costs £180 (without the upgrades, which were £65) and the Dorado is £60.  I am asking £160 for the pair including P&P to a UK address.  Paypal or Bank Transfer accepted.
