  1. Dwight at Senn told me I bought the last ones in Senn USA stock, but that was 6 months ago.  He had to order for another person from Senn Germany. 

     

    You could always DIY your own leather versions.  Reuse the retention rings and foam :)

  2. From what I've heard, the current sources for the tubes are the same cascode in

    the same exact physical place. Meaning the same screws you can't remove

    from the triple of small heatsinks. So all you have to do is dump the rest of the

    crap and drop in 4 tubes. Basically the same as the exstata tube version without

    the bipolar output stage. Very simple circuit. I could draw it up in a few minutes.

    The only issue is what the tubes are, and what the power supply voltages are.

    since evidently there are no other heatsinks on the board, likely its not grounded

    grid design.

     

    Probably a couple of hours of board layout max. I could turn something like that

    around in one day, and get pcbnet.com to deliver boards in 3 days.

     

    Its going to sound way better than the mosfet pile of crap. And be pretty much

    identical to tube based stax product of the middle 1970's.

     

    Still going to be built like shit.

    If this is true I really hope it's not just the tube version of the exstata.  That amp sounded quite bad...

  3. I'd really like to see Schiit make a budget electrostatic amp, I bet they could do it.  We have enough expensive ones already :P

     

    As for the LL, the protection resistors are definitely a cause for concern and the output capacitance is eye popping.  Nobody would accept a SS dynamic amp with Z out of 150 Ohm.  I wish I listened to this amp with more than one headphone so I could better gauge the sound, but it seems like this is the electrostatic equivalent of those head-outs on receivers.  Just changing the output transistors would make a world of difference so hopefully he does that if he releases a new revision.
