Simple Watson; Pull the electrolytics from the Super Zeros crossover, replace with high quality metallized polyproplenes, replace wire internally with better quality Kimber or something. Imaging, detail and dynamics will improve dramatically for about $60. Done mine for a travel system and they even have (some) bottom end. Yeah, really! Good Luck.
What is the weakest link in my C system
Looking for a sound advice on the tweaks in my "budget" system, which I'm pretty satisfied with, but the quest is always to make the sound a little better. CD player: Cal Audio DX-1, analog out via Straightwire LSI Encore to Adcom GFP 565 preamp; bypass out to Rotel RB-980BX via Straightwire LaserLink and normal out to NHT SA-2 via Radioshack gold; and then Kimber 4TC from the Rotel to NHT Super Zeros and BIG copper caples from SA-2 to NHT SW2. I am in the process of finding/making High Pass filter in the signal between Pre- and Power-amp to improve the headroom of the Super Zeros (any advise on that would be great!) So what cables do should I replace (never mind the Radio Shack, thats temporary) , and with what at reasonable prices? (I'm still in Graduate School). Any suggestions would be greatly appreciated.
