  6. The Headcase Stax thread

    if you read the French forum, the manufacturer has already decided

    that 1:5 transformers cause all sorts of grief, and now they are making

    1:14 and 1:20 transformers.

     

    As far as I understand, there are several transformers in this box : one transformer with 1:5 ratio, to be plugged on a OTL headphones amp with "medium" voltage output (around 100V, what the RKV claims), and another one (in beetween 1:14 and 1:20) to be plugged on a regular speaker amp, as for these brave old SRD boxes.

    I may be french, but there are simply too much words in some posts on this french forum to extract the exact meaning of all this  ;D

    French audiophiles like there sound coloured.  ;D

    :P

     

    Anyway, could the "transformer path" be an interesting low-cost option for an entry-level Stax amp ? Something like the old SRD-X/P with a class-d chip, more powerful than automotive audio-chips used in SRD-X/P. Or maybe would it be totally irrelevant versus a brave SRM-252s ?

    the heatsinks on the regulator transistors limit the energy to about 2 watts each.

    So what they do is limit the pre-reg voltage, on my line voltage, its about 380v

    not a lot of headroom.

     

    this is one of the many differences between this thing built well, but on a limited

    parts budget, and the massive overkill we typically do.

    It's not so much about your wallet, it's more about the wait times (which I completely understand the accountable factors in lead and wait times).

     

    I was 90% close to ordering one but my local dealer wants nearly $9k of smackaroos for the RK50 pot iteration and if I ordered through Head-amp I save big $$ (including shipping costs) but the wait times a downer for me as I have no patience to wait for things.

    The more or less year of waiting time is part of the deal, as far as I know. And I'm extremely patient.
