  1. Head-Case exclusive!

    The result of Round 1 of the Stax vs. Senn battle is not pretty. The HD600 lies wounded, in two pieces and sans cable.

    To add insult to injury, the Airbow SR-SC1 and Lambda Pro have taken the HD600 and HD650 boxes for their own use.

  2. Thanks! Completely forgot about PartsExpress, they have the Harrison 6 dB for $26 or generics for $6...i'm going to grab one of them.

    Hi jpak

    I tried the 3db Harrison's from PartsExpress a few years ago, thinking that just a little attenuation might be alright, but they degraded rather than attenuated. I don't remember all the specifics but I do remember that I tried to use them on quite a few occasions and had to pull them out of the circuit each time because they ruined the high end.

    IMHO, I don't recommend them for audiophile use.

    Maybe they are better now.

  3. That jack I believe gives and output impedance of 120 ohms. The damping factor is effected by the ratio of output impedance to input impedance of the headphone. The 120 ohm jack is for a time when I believe there was a standard output impedance of 120 ohms in professional equipment, and some headphones were therefore designed with characteristics to work optimally with this.

    I don't know of any current headphones that are designed this way, and in general, you are looking for the lowest possible output impedance to give the highest damping factor - the bigger the difference between the output impedance and the input impedance is, the more control the amp has over the headphones. If the the output impedance is higher than the headphone impedance, the headphones are actually in a way controlling the amp - i.e. not good, unless somehow by a luck of synergy that makes them sound wonderful!

    If that is the case, why include a High Z jack?

  4. As I said in the HF thread, I think your issue of roundedness might be due to using the high output impedance jack, which really isn't the best idea for either HD650's or (especially not) K701's.

    I really think it has to have something to do with that, because you and I tend to hear things pretty similarly, and I'm not much a fan of a rounded sound.

    Hi I_D

    I just found this site.... :dance: a bunch of familiar names.... what's everybody doing here and how come no one told me about it until today? :mikey2:

    Anyway, I want to ask you why the high impedance jack isn't the best idea for 650s... I suppose it isn't good for 880s either? What was it designed for?

    Anyone have a chance to compare the Opera to a GS-1?
