I will be trying this for sure. Traveling at the moment but will give it a go when I get home and report back with my findings.

I just replaced the Dexa output buffer op amps with some remaining Sparkos I still have. So now I have all Sparkos in both DAC and preamp. (3 stages in DAC and 2 stages in preamp). The sound is now the best I have heard it. I think it may need just a little bit more snap, but 5 stages of Sparkos definitely sounds great! One thing I would advise, if you had the ability : http://s824.photobucket.com/user/ainami/media/electronics/AD797_Sparkos.jpg.html I have found that soldering a 47uf Nichicon Muse (50V) plus a 0.1uf MKP directly to the +/- power pins of the op amp significantly improves the sound quality. It gives more punch, smoother response, and removes the frizzy highs. It just sounds better. |
Hey Auxinput Pardon my tardiness. I have and not to my surprise decided to keep the OpAmps. I feel I gained so much more soundstage up and to both sides. I have also spent a couple of bucks on treating my room. Curtains and DIY panels. I would almost go as far as saying as I feel I have a new system. Thanks for your input. |
