As Seriously_Tho pointed out, it's an overly common standard IEC-style cable. If you live in the US, your local Goodwill (or other donation center) should have a dozen or so of them laying about for super cheap. I have tons of them and I would offer to ship one to you but it's not even worth that.

Just received my D1 and I have a couple of questions, which might have been answered in the monstrous thread which is virtually impossible to read trough.

This is why I will try them here if any of you knowledgeable folks can help me:

1. What is the better method to connect it to a Mac? USB or Optical (I see that USB wont be bit perfect if music is 44.1)
2. Is there a Mac USB driver to fix the USB connection to 44.1 like there is for Win?
3. How come iTunes volume control still works when it is connected via USB? Does that mean the signal it sends is not raw? Does it affect the sound quality?

That would be all.

Thank you very much for your answers!

1. You will have a raw output with an Optical cable, probably better. I find that if I want to listen at really low volumes(usually at night), I turn the amp to around 8-oclock and then adjust digitally. This is because my MS1000's are easy to drive and the attenuator's stepping isn't the greatest.
2.NFI
3.Signal is slightly processed, but TBH I couldn't hear a diff between USB and Optical.

Not currently. You would have to find a C-Media driver for Mac and then modify it. I know nothing about Mac drivers and I don't own one so I never pursued it. Same for Linux.

A Quick Question...

I just received my D1 today and I am playing with it.

I had a question about the Tube output portion of the system. First off, I am a total newb and you all will have to pardon my ignorance. Second, my question... Is it okay for me to run an RCA to mini cable from the tube output. I have a little stereo with fairly nice speakers in it, and it has an AUX port on the back. Typically I just connect my ipod to the AUX port to listen through the stereo. But I wanted to try something different and listen to the TUBE.

Anyways my setup. iPod hooked up to the Analog In via a LOD to RCA cable. Then TUBE OUT through a RCA to mini cable and eventually into AUX port of the stereo and out the speakers.

It sounds great. I just didn't know because someone mentioned that the TUBE output runs HOT. So I didn't know if it was okay if I run it into a mini and into an AUX port.

Thanks all.

zdkaiser, I would say it's ok, but I'm not an electronics engineer. I would imagine the input is run through some solid state components before it's sent to the speakers. The concern about the tube output being hot is only for connecting speakers/headphones directly to it and the voltage may kill it.

Another question.

How do I get my audio to stop crackling/popping while using the D1 DAC?

I am using Foobar v1.0.1 with Vista Home 64bit. I am running Foobar with ASIO4ALL v2 and I am getting clicks and pops every so often. I thought the DAC was supposed to provide a clear/silent signal. I don't have any computer sound effects, just occasional crackles/pops. I have also tried DS, KS, WASAPI with the USB DAC with the same results. I have installed the updated driver for the D1 and set up my sound settings to support 24bit/96khz files. Under the Foobar DSPs, I have nothing running. ASIO4ALL is doing all the conversions between my 16bit and 24bit files. Regardless, I get some crackling/popping noise occasionally.

What could the problem be?
Any ideas?

This is supposed to be the circuitry turning off when there is no signal. Some video players will completely cut the audio signal while seeking. Surfing the web and using a chat program will make it static like that every time a sound is played. I dunno why its like that but it is.

Does anyone know what is the DAC chip in the D1? Does anyone have a schematic for this unit?

Thanks!

Someone talked about it in the original thread but it was never confirmed by Ryan. I didn't put it in this thread because Ryan didn't want it publicized and we don't know for sure which it is.

Anybody knows if Ryan is going to release a new version soon?

He's working on 2 other projects, one of which I know is a new amp. I think he has too much on his plate to release a new version, at least with a lot of changes. He might modify a thing or two but nothing major and nothing anytime soon.

But nothing comparable to the quantity of inputs and outputs of the D1, right?

Assuming you're talking about the amp I mentioned, it's only an amp. I don't want to share too many specs but it's meant to be used with the D1's preamp output. It's not meant to compete with the D1, but rather complement it.

That's a long ass thread!

Anyway, another question: Can you please tell me what's the function of the 100uF 100V caps C73 and C74? Are they passing any audio? Can you please tell me which electrolytic caps are passing audio in the circuit? I want to try replacing them with Elna Silmics which have a great reputation for audio.

Thanks!
