Capacitor upgrades are one of the better ways to improve component performance.. The next upgrade would be resisters in the audio signal path.. it will improve speed, transparency and micro dynamics and is well worth it.. One of the main differences between the Mega Buck components is they use the best capacitors and resisters (clearly for a reason)... It is however very important to only replace them with the same exact values.. Some of the best caps I have encountered are Teflon Film Foil units, there are a few one the market but the Solen Green cased caps (yes Solen) have the best price performance ratio... They sound best after about 150 Hours of use.. On resister issue I think Tantalum are the best, Tantalum is not a brand however its the resister element used ( a rare metal ).. There are also some great sounding NOS carbon units as well... Research techniques and procedures a little If you are going to solder them in yourself... and have fun... Peace
