Stax SRM-323S

  • The STAX SRM-323S Headphone Amp has excellent performance for not only musical reproduction but also for monitoring purpose of professional use.

    High Quality non-magnetic resistors of audio grade are employed for the main circuit of the new series STAX SRM-323S Headphone Amp, greatly improving the tone quality.

    The STAX SRM-323S Headphone Amp also features another Improvement: the circuit constant has been revaluated in detail to improve the sound quality. The signal path is configured with a Class-A All-Stage DC Amplifier Circuit with no coupling capacitors. Carefully selected low-noise hybrid pair-matched dual FET has been employed for the input stage to configure a single-amp balanced output circuit. The result is natural and clear aound regardless of balanced or unbalanced input.

    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 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.
