...i have 2 indras' in my system and found the second indra did,in fact,improve upon what the first cable significantly contributed to my system but by only another 10% or so.that being said...i still kept the second because that 10% was synergistic with the first indra and once in the system i wasn't going to take it out.i tried the first between sacd and preamp and the 2nd from preamp to amp.they are the best i/cs' i have heard.
