Klein DAC II owners thread

Recommended Posts

I have been researching the akm chips recently. From what I can gather in dsd volume bypass mode the 4490 and 4497 are identical. The improvements in the 4497 compared to the 4490 relate to pcm, may in fact be worse for dsd as the 4497 uses more power.

Also, performance at dsd512 is not guaranteed on the 4497 - they have a disclaimer. Dsd256 is no issue on either chip.

AudioGeek - you are certainly on the ball re tech details. Actually I already have a sample AK4497EQ DAC chip & have built up a prototype.

I have done some brief comparisons between the two & there does not seem to be much of a difference. In the Klein DAC I run the AK4490EQ at 6.8v (max 7v) for the analogue section & that is definitely better than 5v sound wise.

With the AK4497EQ the data sheet does not show a 7v option for the analogue section so the AK4490EQ seems to have an advantage there.

With my new upcoming DAC/Pre there will be a very reasonable cost upgrade option to change the digital board over to a AK4497EQ version if desired. It is modular with a totally separate boards so it is easy to swap the small digital board. The Amanero USB unplugs so that can be swapped over which reduces the cost. 

When I get more time I will do some more in depth comparison between the two chips & report back. I think the AK4497EQ may be delayed for commercial production - it is past the ETA now. I keep quizzing AKM about it but get no response.

There is glitch we are working on where the old one keeps popping up

Glitch now fixed

Hi Clay,

do you have plans to use this modular approach for your standalone DACs as well?

Hi Matt,

I had not really considered building just a a DAC like that but I will certainly look at that possibility.

With say the Klein DAC there is not enough room for modular contruction but with a larger version there would be.

Thanks, I mean that both the DAC module and the PS module from your DAC/Pre fit together in one case which is much smaller than the DAC/Pre.

Linn changed the chip manufacturer and use now AKM chips in their new Katalyst DAC as well.

@scumbag Next week, I will be a proud owner of a Klein DAC II! That is once I put the money down and not before! Will definitely compare with a DAC or two like Gungnir Multibit!

This comparison I would be interested in :)

You can thank atsq for me getting the Gungnir Multibit! He offered me a great price for the one he had!
