Title: Can I use my Shure SRH840 with Crack??
Post by: shelby1420 on December 06, 2011, 09:11:23 AM

Sorry folks if this is a dumbass question, I know nothing about this kinda stuff, first time listening to headphones, using them at work with an old receiver and CD player, sounds pretty damn good.  Just curious if I can make it even better???

The impedance is 44 ohms and this would be a much better match to a Smack or S.E.X. kit. The Crack is for high impedance headphones, 200 ohms and higher.

Ok, thanks Doc, one last question for ya....  the integrated I am using stes the headphone output to be ( 80w/8 ohm- 1kz) 650mV+- 10 %................. what the heck does that translate to in ohms?????

It does not translate to ohms. The part in parentheses seems to be the speaker output spec which has nothing to do with the headphone output. 650mV (0.65 volt) is much less than the 5 volts specified in the IHF/IEC spec for headphones, and no source impedance is given. All in all, an unsatisfactory specification IMHO.
