    Review of M18PSU – Gieseler Kraftwerk 12V 4A PSU

    Hi custom-made, thanks for the suggestion, I will think about it.

    Review of M18PSU – Gieseler Kraftwerk 12V 4A PSU

    The base model Kraftwerk set to 5v will power a Qutest but will run hot so not ideal. With the Qutest you would be better off trying it with a USB battery power bank. https://www.jbhifi.com.au/cygnett/cygnett-chargeup-pocket-8000mah-power-bank-with-integrated-lightning-cable/342074/ You could try it as a test & see how it compares to the standard supplied SMPS unit. However I think the general consensus is that a linear PSU does not make much difference with the Qutest. For a small improvement the iFi unit is supposed to be quite good. https://www.ebay.com.au/itm/iFi-iPower-5V-Audio-Power-Supply-AUTHORIZED-DEALER-/132481695739

    evil is correct, due to the low 5v output trying to get anything more than 1A causes heat issues with any of my current linear designs. A 5v at 5A unit is certainly possible but it would need to be a new dedicated design & based on a switcher which I’m not keen on.

    Amanero mystery

    The Amanero board is powered via the USB socket so relying on the power from the PC. This is pretty standard even with some expensive DAC’s. In view of this with all my DAC’s I disconnect the USB power input & power the Amanero with a ultra low independent supply from within the DAC.

    Anechoic chamber visit

    Anechoic chamber visit

    Blade74, Hume still owns the factory which is now rented out. The anechoic & test room is just being cleared out now. He is retired but doing a lot of international travelling & moving to a new property at Lenox head. It was quite a ethereal experience being right in the chamber - even you own voice sounded weird. The room is divided in half horizontally with a grid so you are literally suspended in the middle of the room.

    Amanero mystery

    Sounds like it may be the Amanero board but the intermittent part is puzzling. It might be a good idea to bounce it off Dom at Amanero. I will PM you his email.

    Yes it is possible but unusual that it was fine for a couple of days. Have you got another digital source you can test it with?

    Anechoic chamber visit

    Hey guys this is amazing - I am a old friend & customer of Hume & recently paid his factory a final visit. He kindly offered me the remaining speaker measurement equipment & I had also had one last look at the anechoic chamber before it is dismantled.

    Amanero mystery

    Yes you have to clear the old firmware first (erase) as per instructions when you download the firmware tool. https://amanero.com/combo384_firmware.htm If you don’t erase first you will get an error message.

    I would definitely try reflashing the firmware. For Windows 10 I find 1099c the best - you should then be able to play DSD512 perfectly.

    AKM new Verita AK4499EQ dac

    Sample chips now ordered. ETA January 2019 so I guess I better think about laying out a prototype PCB. Also time to brush up on I/V output stages.

    Klein III owners thread

    Input selection on the Klein III coax/optical version is via a front panel toggle switch similar to the Klein I & II.
