Does a Class D amp match well with Thiel Speakers?

Again, you may consider a tube pre...in order to 'soften' the sound.
The THIEL can be, depending on the other gear in the system, somewhat 'dry' sounding. Potato, potaaaato.
I always preferred them with a tube somewhere.
Kathy Gornik, (now owner of THIEL) and I used to say, laughingly, 'I never heard a solid state amp that I didn't like better with a tube preamp'....the meaning clear, especially in the context of THIEL speakers in the chain.

Put me on the Spectron side of this answer.
The 'only' issue is THIEL's propensity toward an analytical sound...usually ameliorated with tubes in the preamp stage...just sayin'.

Good listening.

Soundlock makes a good point.
Jim Thiel, starting in 1988, while developing the CS5's discovered that, by using bass drivers that drop precipitously in resistance, that this had a side effect of pulling more current from the amplifier--acting 'almost' as an equalizer on the bottom/bass region.
I have not discussed this, but it seems plausible, AND if Jim said it to be true, I don't need much else to bolster this opinion.
So...with that said--an amp with lots of balls, doubling as the impedence drops more and more, as they do get into the 2 ohm region with the THIEL 3.7--should mate well with a 'Krell-like' bass performer. I don't ascribe to the Magtech amp, as I haven't heard it...yet, he's right on the mark in his assessment. THIEL's need current.
As a side note--one very hard earned lesson by Jim that year was, that virtually everyone exaggerated their current delivery on the amplifiers--very few did what the manufacturers claimed.

Good listening...

We're in total agreement.

Good listening.

There is an incredible struggle going on in design work.
Design is about 1's and 0's, X's and O's--formulas.
Music is about emotion and feeling, (think Micarelli playing Emmanuelle with Botti or, you name the piece).
The two posters here, duking it out are a perfect example of the thoughts which tug at a designers heart (and to be truthful, purse strings).
At what point does my speaker sound 'flat and neutral', and then at what point does that (even 1/4db difference in output of the tweeter, give it an overly analytical sound, or, God forbid, 'bright and hashy'?
I personally went for this: "The best tweeter I ever heard, I didn't." Try to tuck the tweeter in right beneath the midrange--measures flat, but never, never calls attention to itself. Also, chose a tweeter that doesn't 'spike' in the last octave, (10Khz to 20Khz). At least the last octaves for most of us...(note: does not include your favorite Akita, or Corgi.)
The problem with this 'careful balance of loudspeakers is', that that damn 'free will' thing rears its ugly head.
One designer of a THIEL like sound is realizing that the customer NEEDS some electronic 'help' while another is thinking the exact same thing, but hoping for the opposite 'voicing' of electronics, say Vandersteen/THIEL.

I was wondering if this debate would develop and I'm glad it did.
Personally, I went for a 'really dynamic midrange', flat but not too forward high end...and think that that's what we hear 'live' in an accoustic venue.
The third, most important diminsion in audio is the listener, his/her preferences. Interesting.

Good listening.
