Digital Cable Recommendation

audioquest vsd 1 is very good and wont make you poor, also look at some lesser known generic brands as depending on what level of equipment your using the difference between digital cables can be very small ,the audioquest is what i use. happy listning.

If you really want a price-wise *cheap* cable then it would be Apogee Wyde-Eye ($50 for 1m RCA type cable. Price seems to have gone up ~$10).
Others that I understand are very good are:
Silver Audio Silver Stream
Kimber D-75
Kimber D-60 (this is the much more expensive version that was bought from Illuminati)
DH Labs D-75

The list is rather large so it really depends on your budget, what you are looking for sonically & what type of equipment you have.
FWIW.YMMV.

My three recommendations are from listening experience and represent superior value in their respective price classes... in my very humble opinion.

Level 1--Apogee Wyde Eye
Level 2--Zu Cable Ash
Level 3--Wireworld Gold Starlight

I can also highly recommend the Apogee Wideeye. For 'bout double the price of 1 meter Apogee check out the Stereovox HDVX, it's excellent in my HT system.
