EDIT: Thanks for the help. I bought a Musiland 01USD 2012 edition which recived good reviews: http://hifiduino.wordpress.com/2012/05/31/musiland-devices-reader-review/
The thread has so far not let to any conlusion regarding the importance of a quality USB -> spdif converter and nor has anyone agreed on a point of diminishing returns.
I was lucky to get a very good DAC for cheap directly from the manufacturer, because he was closing up. Since then I have been looking to upgrade my usb converter because it's a 20$ dollar toy from ebay.
Here is my equipment:
Laptop -> 20$ USB converter -> 3000$ Danish Audio Design DAC 10 -> 200$ DIY tube amplifier -> Sennheiser HD600
My question is: Where do I spend my money?
1) 100$ M2tech hiface usb converter + 200$ to upgrade my amplfier
2) 200$ Audio-GD digital interface usb converter
3) 350$ JKSPDIF MK3 usb converter (this option is pushing the budget)
4) Other suggestions?...
What do you guys think? How important is USB->SPDIF converters compared to amplifiers?
