I need more cowbell....

Audiopoints beneath Thiels are a great idea -- I found that they make a very noticeable difference. Glad you did that, but you already took my first recommendation. My second is to go to MIT and you already did that too. ;-)

So, let's go far deeper into the bag of tricks. First, how long have you had the 3.6's? If you are real handy, you may want to consider replacing the caps in the cross-overs. High quality caps all have their own sound -- you might want to contact Thiel and inquire about the need for replacements after x years, the type of recommended replacements and whether that should be done by a pro.

Second, I assume you've tweaked the speaker placements. If not, that's always a great thing to do -- and very time consuming. There are lots of good threads on that here.

Third, have you tried the Porter Ports? i.e., the cyrogenic outlets from Albert

Fourth, did you decide to stick with the stock tubes because you prefer them to others? If not, some tube rolling might be fun. Sorry I have no suggestions here but there may be threads on that topic (or you could start a separate one if no suggestions are forthcoming).

Fifth, what about acoustic treatments? Are you using any now?

Good luck.

Sounds like your happy with your speakers. Find a tube amp w/balls (bass) that can drive the Thiels and you might get something more musical out of them. I've always found Thiels sort of sterile w/ss amps, even vintage Thresholds, but they do need the current found in big SS amps. A good 160 to 200 wt tube amp could be just the thing to get you closer to music.

Some time ago, I demo'ed a CJ 14 in my home. Way too subdued. Get rid of that preamp, and you're off to a good start.

"I'm burnin' I'm burnin' for you"

I am always amazed when people ask for upgrade advice, folks give their opinions when it is never discussed what you like or don't like about your present system. When this happens it is a recipe for disaster. Like grasping in the dark, findin a needle in a .......... well, you get the picture

I would love to give you some suggestions, and I think others would to, but I think that it is really important to answer the above question as well as the type of music you like, volumes you listen at and musical reproduction values.

Afterwhich, the advice you get might actually address your needs. I hope this helps!
