I'd go along with that :!:

I went through the Lampucera thing and posted my thoughts on AOS a bit.

This one is more detailed and involving than Lampucera. Though i sometimes think there is a slight lack of dynamics from this board. Maybe this is because the DAC has an "easy to listen to" nature. Others may disagree.
Generally speaking, its a good step up from Lampucera, worth the dosh and a bit of effort.
Much to learn there is.

Hence why I still haven't got my vinyl working again. Now that is really saying something. I couldn't live with digital last time I was in this hobby. digital has come on leaps and bounds.

A thought I have been considering myself. I think (though dont yet know) it might be ok, what I was finding was that as long as the two halfs are in perfect balance its fine, but the moment the nickel lams see a slight imbalance they saturate hard. That may be fixed with parafeed, but I am not sure as the problem is not just about DC. I am in conversation about the topic with Bud ATM.

Be interested in what the outcome is Nick. Some new transformers perhaps?

So do we think that the AK4396 can drive a capacitive load OK? I think at one stage there was some thought that the switch from AK4393 to AK4396 had introduced problems. Or was this a red herring?

Yes I believe so. measuring Ali's and previously, I have seen no problem. I read the spec sheet as saying some things that have been conflated together.

It looks to me that the output needs at least a 1k load (1k5 at DC). Max direct load on the output is 25pf. If its driving more than that, it needs a resistor in the output. As long as the resistor is more than 1k5 it doesn't matter what capacitance its driving.

OK, thanks very much. My 96 board is on the slow boat, but I've got plenty to keep me busy til it gets here :D

Well my AK4396 kit has arrived.
When I got my AK4393 kit, the three SMD regulators were already fitted to the board. This time they aren't - so can anyone give me any tips for soldering SMD devices?
Obviously good eyesight and a steady hand would help but they aren't available :lol:

Get a flux pen, I found that helps a lot, let the solder flow where it wants. There are some good videos on youtube about soldering smd parts.

Rather than start another thread on this here DAC, may I butt in and ask a question?

I can? Goody :D

I fancy getting one of these DAC's for the SPDIF output from my media computer's onboard sound.

Question is: I have a Toslink cable, is it just a case of cutting the plug off one end of that cable and attaching the two cores to the input of the DAC? Assuming there are two cores of course, I haven't cut one up before.

And then taking a common screen and left and right analogues out from the DAC?

NO you will need the Toslink cable and one of these converters works brill
