That rules! I have a Prelude and the only thing I have done to it is replaced the OPAMP with one that Auzen now sells (Texas Instrument's OPA637). Are the Prelude caps cheap? I kind of assumed that they would have high quality caps on their cards...


Also, are you going to do the ERS paper mod? If so, can you please let me know what you use for insulating material? The mod is referenced on Headfi:
