I'm not putting down 75 bucks if I can just use a wallwart. Any recommendation for european users?

Why do you power your DI-V3 with a switching power like this? It will not produce good sound because of the noise. You should look for a linear power supply instead, like the one sold by Audio-gd.

Following your reasoning, you already put down 150 then.
Power supply makes a big difference, if you don't want a quality one, then you'd better stick with USB power.
Unless you're using a device that cannot supply 500mA?

I have exactly the same problem too! Firmware #10 is installed. SBT recognizes the DIV3 via usb output, but the dac gets no sound. Usb from pc works perfectly. Coax from SBT too. If someone finds a solution (KingWa?) I would be very happy to hear it.

A common wallwart is worse than plugging into USB direct.

A better wallwart might be worse or just equivalent to plugging into USB direct.

A good quality one is likely to be nearer to 75 bucks probably.

Hand over 75bucks or pay nothing at all, plug into USB direct IMHO.

Some people cant even hear a difference even with 75bucks handed over. biggrin.gif

IMHO, those who have DI-PSU please consider to buy / tailor-made a DC-DC cable between your DI and PSU.

 

My colleague bought DI-PSU a while ago and I think it was worse than Lithium battery for it lacks of the clarity. He then DIY a few cables and finally made one with inexpensive industrial power cable. Once switched to that DIY cable, it is as good as my best lithium battery. I must say that the DI-PSU did a very good job here but the full potential is waited to be unleashed.

 

Lithium batteries are not born equal too. I tested a few lithium batteries and my opinions are:

 

1. SANYO 18650 lithium battery provides a clearer / cleaner sound than USB but lacks of the dynamics and bass. I wonder if it is due to a lack of max. discharge rate, which is 2C only. Another colleague advise me to add a few capacitors and I will test it later.

 

2. E_sky 20C lithium battery for Remote controlled toys sounds the best amongst the batteries I have tested.

 

3. Another no branded 20C lithium battery, for I don't know why, tends to have a noticeable blur sound compared to E_sky.

@Jecklin Stax

 

Have not recd. your personal message. What does "en ktm77" mean?

I'm sorry I did not make myself clear. 'en' is Dutch for 'and'. 'ktm777' posted the same problem as you and I have: Although we have firmware #10 in the DI-V3, we still don't get music from the USB output of the SBT!

As I wrote before, I'll probably send my SBT and DI-V3 to the Audio-Gd service in the mid of September. As I know there are at least two service workshops in Europe - in Poland (were I live) and in France (Audiophonics).  If they will find solution, I'll let you know :-)

Does A-GD provide a coax cable with the DI?

Only as an extra

Alright, so I got the DI-V3 and PSU in. Besides the clock, there was another socket thing that came with it that looked like the one near the usb board connector (the green one) as seen in this picture:

 

 

What do I use that for?

post #3943 of 3990

That should be the spare firmware chip of the USB32.  Don't have to worry about it for now, just keep it as a spare.  That's what I've been told in the email when they sent out the 10ES2 to me.

The small green pcb was the USB32 firmware, which determine the functionality of the USB output.

You may swap or flash it to hear differences sound wise. More for those who uses SBT EDO.

Oh, I see. That actually makes sense. The unit actually gets quite hot (probably due to class A), do you think it's a good idea to stack it ontop of a NFB-5?
