Thiel Owners

I took some measurements with the miniDSP mic and REW software to see if the new COAXs I installed (plus other wiring fixes) have resolved the SPL issues. I now see a beautiful LEF and RIGHT measurement chart with everything overlapping, just like my KEF LS50’s. Halleluiah!

So my take away from all of this for any one looking to get a CS3.7. Even a massively screwed up one like mine. The speaker can be made perfect using Rob Gillum as a resource. All this work was done at home by me who is a novice on electronics.

@thoft. FWIW I used an Adcom 555II on the 3.5's for years.  I installed a high quality passive stepped attenuator in it and ran my DAC directly into the amp.    I now use an old Superphon preamp into a Classe C300.

I'd say the Adcom set up gave me about 70% of what I'm hearing now.
Unfortunately I never did run the Superphon with the Adcom, but if experience with the Classe is any indication, the Superfon makes for a big improvement over going directly in.  I had bought into the 'less is more' philosophy on line level inputs and now believe that was a mistake.

All my non audiophile buddies where always very impressed with the old set up and I enjoyed it, but knew the Thiel's where cable of reaching another level.  

A word of warning -I've owned a bunch of 555II's and destroyed the woofers on a pair of Infinity Kappa's when one amp went bad.  After that I had that I had the amp driving the 3.5's check and serviced - but was always a bit nervous.  

With current used prices on 3.5's being as cheap as they are, the irony is that to really hear what they can do, you need to spend a lot more on what you feed them than you did on the speakers themselves to really hear their potential.

Bone dog, in regards to the new midrange finding maybe that’s why I find myself listening to string instrument and jazz songs. Midrange is so clear transparent and accentuated unlike the imf I had so I’m hearing things I hadn’t beforehand.

Also bonedog someone on the adcom group over on Facebook made an little unit to go in between the speakers and the amp that is a protection block. Something I will be investing into despite that the adcom 5800 has no signs of anything bad in it now or anytime soon. It does not mess with the signal in any way shape or form. The guy is a genius.
