AK4490 USB Dac with dsd support.

In my opnion it is the 3. I have a little bit more air and better decay.

But it is a taste..

Hi Sonny,

Could you sell me four of those buttons? I need some for my front panel.

Thanks
Do

Yes I can

 

[pinnocchio]

Yes I can

Would they work with the preamplifier display? If yes, can you send me a PM with pricing for four?

Thanks
Do

Sonny or anybody else,

Can somebody comment on the performance advantages/disadvantages (subjective and/or measured) of DSD direct (volume bypass) and how that impacts what oscillator one can use with this DAC (AK4490EQ)?

Thanks,
Anand.

Hi Anthony.

Got you the problem solved with SPDIF?

 

[AnthonyA]

Hi Anthony.

Got you the problem solved with SPDIF?

Yes got it to work, thanks

Hi Sonny

Is this a safe way to connect xlr to rca?

I currently disable pin 3.

 

[sonnya]

Hi Sonny

I currently disable pin 3.

And that is the correct way AnthonyA to run in single ended. I have not made it active balanced, In active balanced you can short pin 3 or pin 2 to ground and get the double voltage swing on the opposite pin

Can you please make one post with all info about new DAC..

Hi Sonny

Will the 5v dc supply work well with just 4.9 to 5v supply?

 

[Joseph K]

??? 5V dc supply?!

 

[AnthonyA]

Yes.. Digital supply.

 

[pinnocchio]

Hi,

Anyone can tell me the pinout for J3 and J4 on the new DAC OPS?

Thanks
Do

 

[Joseph K]

Anthony,

The only digital supply is 5,5V.
This is what you have to feed to the board, together with +/- 15V.

Or did you mean J11?

Pinocchio, do you mean the onboard balanced output connectors?

They are like this: (top view)

Se- | Se+
Gnd | Gnd
Se+ | Se-

The (+) amplifiers are summing the balanced dac outputs into Se + signal (upper row, below connectors)

The(-) amplifiers are inversely summing the balanced dac outputs into the Se - signal (bottom row)

(A very nice find from Sonny)

Pinocchio, do you mean the onboard balanced output connectors?

Se- | Se+

Yes, it was the onboard balanced output. Seems like they're exactly the same as the previous discrete output stage so I didn't have to change anything!

Listening starts tonight! Yessss!!

Ciao!
