What has been your most satisfying component?

I would say the most satisfying has been a modded Jolida JD 100. I've had it for over 2 years -almost got rid of it before. Until I started adding better and more compatible amplication and speakers (that dreaded synergy thing) I did not realize that the Jolida could play this well. But like most, the quest goes on to optimize my system. I'm counting on receiving my upgraded Modwright 999ES and the addition of Xtreme Quicksilver Gold to fully realize how good the rest of the system can be. The Ouicksilver Gold on the tube pins of my Jolida by itself has taken the sonics of my system to another level. The Quicksilver Gold has bested the Walker Extreme SST in my system. I have no afilliation with any of these products, this is simply my experience in my system. A fellow I communicate with named Mark (1Markr) in Chicago (part of that Chicago group of audiophiles (Mark, Bon, of Bon Mod fame etc). who've had the legendary Modwright Sony,999ES and 9100 ES etc shootouts) recommended the Quicksilver Gold- you were right Mark!- it's the bomb Thanks.

Aesthetix IO! Not even close.

Resolution Audio CD-50, this player provides such detail it truly amazes me each time I play a well known cd on it for the first time. Listening to Jeff Buckley -- Grace now, and sure enough I'm hearing music that was missing before.
Meadowlark Audio Kestrel Hot Rods a close second. They're in the closet now but they are fantastic for what I paid for them.

Music Reference RM-10 tube amp. Has made me a very happy person after going through more than a couple amps. Sometimes less is more.
