Audio Enhancer

[billdean]

I am using a sdc-2300. I am pretty hard of hearing and would like to no more about which audio Enhancer is best. I am using Sun Ray Pro Gold CTX head phones but I am still having some trouble hearing those faint signals. I have read a little on Steel Phase, BZ booster, Doc's screamer. Is one better than another?

Friend of mine just bought a steelphase and really likes it.  I’m probably going get also for my scd2300.
