Max Martin, what version is your DAC pcb? There supposedly is a v1.1 version out now.
Did you get a schematic with your DAC perhaps?

Hi,

From Martin's review and my requirements, I have placed an order for 1 unit of this board, hope it doesn't disappoint. I do have a few DACs I can compare with,
1. WM 8741 with CM6631 via digital coaxial
and
2. AK4393 and Xmos via I2S

all these DACs are std configuration without extensive mod., I use tube buffer attached to the DAC output. I will be using this new DAC(AK4399 and Xmos) with tube buffer and CDrom build into a single box.

I wouldn't go with a tube buffer with this one i think. This dac sounds very analogue already.

Remember some mods to do right away if you want it top class.

1. Op amps to opa228
2. Remove bypass on opamps: more coherent. (Or change to ero 1837)
3. If you can replace bypasses to ero mkp1837.
Remember burn-in: maybe 50-100h atleast... And if you want a cleaner, brighter sound , Cerafine on output. I have now filmcaps and that is the best - but bulky.

I saw that they are away, that's what had me confused. I thought you had just bought one, but my search came up empty. Guess I'll have to wait then.

Thanks for the suggestions, my "hypothesis"(*) is that without extensive mods as suggested by you and I put a tube buffer in front of the DAC, the sound reproduction would be similar to your mods without the tube buffer.

* I put a tube buffer in front of my unmodded AK4393 and WM8741,using standard opamp(yet to experiment with other op-amps), both sounded more analog.

I'm interested in getting this - presently have a hifime ES9023 USB DAC.

I run my system off a Mac Mini - does the latest minishow version with the XMOS USB input work with a Mac? Anyone tried?
