Digital Cable Recommendation

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.
