The CMoy can affect the sound, which is a hazard if you're a purist and fun if you're not. It's biggest win is being a fun and accessible (cheap and simple) entry into electronics. A good audio circuit should have low output resistance. Granted you can get that with a CMoy, but the popular/expensive models don't meet that criteria.

That would dissipate about 50% of the power in the output circuit, and unless the impedance variance across the frequency ranges matches the headphones, then it will significantly color the sound (as the fraction of power dissipated will vary from the nominal 50%). Power amplifiers almost always want to be orders of magnitude lower impedance than the loads they are driving (so a fraction of an Ohm for driving speakers) for this reason.
