Does anyone know how to connect a Bottlehead Crack to a Silicon Arts Next Class Si2 DAC?
The main source would be music from my computer. I don't know what cables are needed. Any help will be appreciated.

From their site:
 

Inputs​	1 Digital Input (S/PDIF), Single Ended (RCA)
Outputs​	1 Stereo Pair, Single Ended (RCA)

 
Pair of RCA to RCA from the outputs to the Crack RCA inputs.
Output of S/PIDF to DAC Input.
 
Looks like this is not a USB dac...so your computer has to have a S/PIDF output or a audio card that does.
from a review:"

plus the Si2 DAC doesn't have the right inputs for a computer-based system (meaning like USB)"

 DIGITAL INPUT : S/PDIF digital input terminal. Digital output signals from CD players and transports can be used.
 After the DAC unit is settled into its position, connect digital output (S/PDIF) of CD player/transport to the INPUT terminal. After connecting such input device, connect “OUTPUT” left and right terminals to devices such as preampliers.

Thanks a lot for your help Adydula. It seems like this one would work https://www.amazon.com/Signstek-Coaxial-Converter-Decoder-Analogue/dp/B00FEDHHKE/ref=sr_1_2?ie=UTF8&qid=1483052667&sr=8-2&keywords=S%2Fpdif+to+usb but I'm not really sure.

I guess I'll have to use a pair of RCA to RCA as you mentioned to connect the Amp to the DAC, then will hook up a S/PDIF coax cable to the converter and finally use a USB cable to connect the converter to my computer.

You may just get simple USB dac....versus all these "compromises", cables, convertors and connections....??
 
You can get a good dac for $100.....
 
Food for thought

Note: The device u linked to has a dac in it according to its description and you already have one? Dont think this is what your wanting to do...if u really want to use this dac you have then this is not the box IMO.

Finally stopped my tubes rolling.....off of my unit.

Had them all loose before, with a few close calls of knocking one and dominos to the others, least they're all secure now.

If anyone is interested, 19mm for 6080 and 12.5mm holes for 12au7 tubes.

(Had a novel idea to wire them all up with switch boxes, save having to roll them )

That's a great room display and holder for your tube collection. Really cool.

Hd650 with the BH Crack is such a great combo! Are those HD800 as well?

I got the 650 and 800S on the same day, as couldn't decide in the shop, 800S sounded so clear, though the 650 sounded fun.

Thing is, in the three months or so I've had them, 800S have had ~99% of the air time, amazing detail that just keeps drawing me back to them (of all my headphones)

Nice idea, but whats with the blue tape on your Crack enclosure not glued yet?

He quotes he already has a 1000$+ DAC, so why not use it? I do get your point on the extra connections and all.
 
The product he linked has a DAC in it but can also be used as a simpel USB -> Coax, digital -> digital converter. For that price it's worth the try.

Honestly, I won this DAC from a prize draw at RMAF. It is listed over $1000 and I'm very curious to see how big of an improvement expensive DAC makes. It has been sitting in a basement for a while and now is a good time to actual use it. Thanks all for your help. I'm getting a converter anyway to see if it works.

My guess is that whatever gains one gets from a high end DAC will be lost with a cheap converter. Mutec makes some high end converters, but you would be better off just buying a new DAC rather then getting the muted.
 
I recommend just selling the DAC for no less than $265 and then just get a Mimby. If you think you can get more for it, like $500, get a used Bimby, or pocket ehe money and get a Bimby.

that's right.  got the glue, and some wood oil, but hadn't stained it yet....and glad, thinking i might paint it black now too.

A decent sound card with pci-e could be a nice digital coaxial source if you find the right model. Assuming you have expansion ports available

 

[adydula]

I would sell it and get a less complicated connections solution.....but hey its your $$$$ please let us know what you think???
