    Before I try the Murata regs can I just establish that I need the new Caiman PSU, not the original, since they require 15V to operate?

    Stan - any chance that the new PSUs will be in soon?

    Hi Martin, send me an email and I'll sort you out with a payment request.

    Yes, you do need the Caiman PSU in order to get the Murata to work properly. My advise is to also do the audio PCB caps mod I mentioned in another thread. The two complement each other. Leo has been trying the caps mod with his discrete regulators as well. Best ask him what he thinks of it.
    Feel free to pass by and listen to mine with the mods through my NS1000M and HD800, before you make the plunge. Bring your own DAC and some test tunes for reference.

    Thanks Stan. E-mail sent. I will go ahead and order the components since I am sure it will improve on an already outstanding product.

    I'm not sure how many other users are using their Caimans for Sky HD (optical link) but I can tell you that the sound quality on some HD programming is quite superb (David Attenborough's Life is particularly impressive).

    Yes, I am Martin - stunning on some of the music programs on BBC HD, and MTV HD is pretty good, too. I gave up on surround years ago - crystal clear stereo is fine even with films I find.

    Even better with the huge soundstage of a good valve amp.

    Agreed, Alex, I have no time for surround sound.
