" a simple tweak almost everyone can do is to replace the cheap cap in series with tweeter with a really high end ones. I replaced the mundorf silver/gold with teflon v-cap in my avantgarde omega duos. the difference is dramatic "How would that af... 
Genesis Revisited
Overall, I found the sound quality to be quite good, definitely above average. I'd give it a 7-8 out of ten overall. Some cuts even higher perhaps. Acoustic guitars in particular sound fabulous in this go round and alone worth the cost of admissio...
