Stax SRM-323S

100% Positive Reviews
Rated #193 in Desktop Amps


Pros: price and sound are quite ok

Cons: dont believe those inputs and outputs...

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.
