CJ is notorious for having a lot of gain, the classic has 27db.  The McCormack only needs 2.25 volts for its full 500 watt per channel output.  A CD or Dac output should be 2v.  So the OP should be able to get full output from a preamp that has 1db of gain.  

The only two solutions here are imhififan’s suggestion for attenuators, or a different preamp with less gain.

If the problem exists with his Oppo 203 then the solution is to go into the set up option on the Oppo and set a max volume. This will enable him to run his CJ at a higher volume.

There is no low gain substitute for the M8080 ( 6C4 ) tube. I use this SCHIIT SYS to attenuate the output of my CDP. It’s worth a try!
