Stax SRM-323S

323s, apparently adds on Slight Low bass, if one sits down and carefully
does a, b testing with a few stax headphones and other driver units.
 
if you are using 407, 507 on this unit,
suggest Strongly to heed following warnings....
 
1.  DO NOT simultaneously stick in 2 headphones in front.
    take one out and listen.  quite a big difference. eh.
    next test, try the other output...there is also a tiny variation
 
2.  DO NOT  use the parallel OUT on back.
     i did.
    learned my lessons...  do your on, off tests and see yourself.
    huge time/sound smearing... even with pre amp off and unplugged from power line.
    also, in my case, this STOLE midrange and high frequencies too.
 
so there u have it...things no one men tions or wants to know but only bitches about
sound not being to liking. myself included.
 
my overall too much bass for MY ears remains...so i use that tissue roll up thing...but
now i got my midrange aqnd high freqs  back !
 
so, for those that feel there is too much High frequency,
use the above ideas to change your sound !!  you can use to advantage...too.
 
thanks
