Hey jft,

Did you receive this cable recently ?
If so, can you email me about it (I actually need to know your email address, but you don't need to mention it in this forum).

Plugged in USB JCAT FEMTO USB card 5V  Nothing
Plugged in regular USB  Nothing
" While the T+A DAC 8 DSD does not require the 5v as an operating voltage supply, it does require the 5v for identification. That information comes directly from T+A in Germany in response to my query. I believe that this is commonly referred to as "handshaking". Related?

Hi Jack,

Yes, in the power inlet two fuses reside. In the box your NOS1 was shipped with, you may find a couple of spares.

@Ramesh, your idea is good, but if the light lits, the battery won't be empty (the battery provides the light as well as the power to the meters).

Let me know how you fare, Jack.
Kind regards,

A simple thing that you've probably already checked.  Is the battery dead? Have you tried replacing it?

Hi Peter & all
I have always left all my system on 24/7. We had a local power cut in the evening recently. Everything went off then maybe 30 mins later all back on except the PC which did not have restore power set in bios. Next day I turn on PC, load XX & get warning that a different sound source is now configured. So I turn DAC off & on & go through the setup procedure.
With switch 4 down & battery connected the interior lights up but there is no offset display showing, the dials are blank. I don't even know if the DAC is on! Is there an internal fuse that could have blown or some other circuit protection? If one of you could stop me from fretting it would be much appreciated...

About the AKM 4493 chip I can say that sounds very good to me. I got the I2S signals from my soundcard before the original AKM 4396 dac chip to feed the new one and it was a great leap in SQ.
Bear in mind that I canīt compare with anything but the DACs I owned before : Cambridge DACMagic ( Wolfson ) and  the original Audiotrak Prodigy soundcard (AKM4396). As a (frugal) audiophile I am completely isolated in my environment. Sad

 I was planning to do the same thing with another broken soundcard I have lying around and the AKM4497 chip but currently is out of stock.

It appears that the author of the article you attached made some fundamental errors in setup when taking measurements. Corrected measurements (by another person) are shown here:

... their power supply seems to be in need of improvement.

Hi Joachim, it's useful that it has a 12V DC input for power. I use a Paul Hynes linear PSU with mine. I haven't tried the stock SMPS that came with the unit, so don't know how much difference it makes. In my case, I don't have any SMPSs attached to my audio mains circuit and wanted to keep it that way.

I have to say that I continue to be very impressed with its SQ as a DAC.

cardboard tubing.

You mean the inner of a toilet roll, right ? my English is not the best, but I think you refer to the toilet roll.

Yea, I tried that. But after a while the resonation went wild.
Then I folded a cold gas thruster around it. This now works well for 3 days continuously. But only at 4G. 3G didn't start and 5G doesn't run reliably.
