Thiel Owners

@thielrules, I measured my 3.7s with a single Cambridge 840w because I felt the bass was lacking.  I did it using test tones and my Behringer ultracurve and measurement mic.  The weak bass didn't show up in the measurements as it measured fine.  I bought a second identical amp to run bridged mono and the bass improved significantly.  The power went from 350 watts/channel into 4 ohms to 800.  The difference wasn't in the volume of the bass but in transients and texture.  As far as recordings go I'd find some with sustained, textured bass and also some with deep and punchy bass.  

This is Edgar Meyer playing his bass with a bow.  Lots of texture.

Lots of sustained synth in this silly and possibly creepy eighties music video from Queen

tomthiel brings up a good point about "sweet spot" or best value. For instance my previous declaration in favor of the Bryston 3B (within appropriate matching with older Thiels) was based upon such a criterion. It's not necessarily one the best sounding amps, but at it's price point it performed quite admirably for the task at hand at the time. Which is quite an accomplishment! It's a lot easier to make a cost no object good sounding (and unfortunately enough examples of the over priced / under performers exist as well) kit, than one that performs nearly as well for quite a bit less.

Since we're talking about amps again: some time ago I posted a plea for a list, however small, of amps that by spec would be completely capable of matching the low impedance needs of the Thiels. Has anything materialized? I mean, besides the Krell FPB 600. Seems like we are stuck in "I like the sound of it, but..." land.

Thanks for any input.

Tms - I would love to see that list materialize. A good handful of offerings have been made. It takes someone to pull it together off this forum. Perhaps you?

My own personal experience suggests:
Bryston 4B3 (cubed) most recent and most refined of their series
Classé DR-9 in any configuration, stereo or mono
Threshold S-500 (Thiel lab amp, updatable) {showing my age}

And my present research suggests:
Benchmark AHB-2 specifically vetted by Benchmark, not heard yet
PS Audio BHK-300
300 specifically vetted by PS, 250 questionable at high gain.

My needs are clean, neutral, capable and affordable rather than 'good-sounding to me'. But then I actually enjoy hearing what was recorded as honestly as possible. I cross-check neutrality with Sennheiser HD800S closed cans and co-play with Beyerdynamic ref 240 ohm.
And 50+ years in hi-fi manufacturing, recording and mastering-consulting have supplied some helpful experience. That's my short-list for my own purposes with my own constraints.
