Low capacitance IC??


I currently having my Squeezebox2 modded and apparently in order to get the best result they recommend using very low capacitance IC that are rather short. Anyone mind explaing what capacitance means. Right now I am using analysis Plus oval 1. Overall I like them but am considering buying new IC from either Virtual Dynamics (audition) or Audio Magic (X-treme)anyone comments. Other recommendation are great. I am looking for a .5 meter pair.

sorry - 20kOhm - was near midnight and after a few Belgian Ales when I typed that. The DAC chip in the SB is rated to drive loads as low as 5kOhm, but at that level capacitance would become very important
