Thiel CS 2.4 Amplifier Pairing

@jazzman7 , both Yamaha are 2ohm stable with no issues I believe. I just have not read any users with Yamaha amps on Thiel.  I would consider integrated but wasn't sure the power would be suffice.  Japanese usually don't carry the heft in sound like American amps.  

It’s a rare integrated that match up well with Thiel, and they do tend to be more expensive fare. (Other integrated amps that I had thought about included those from Krell, Ayre and BAT). With my Bryston 3BST at 125 watts into 8 and 200 into 4 music was very enjoyable. With my Coda, 150 into 8 (w/ first 18 in Class A), 300 into 4 and 600 into 2, there is a grip and ease which the 3BST can’t match.

@jazzman7 The Coda CSIB will move the Thiels with ease.given those specs.   Thanks for sharing your input.  Have you had any issues with the midrange driver needing replacement?

I have owned a pair of Thiel 2.4 for over 15 years now and have had them on multiple amps. Currently they are in a second system my wife uses for TV and background music on some old Rotel mismatched gear.

Power is not the issue but the low impedance is. I think they actually dip down to 2 ohms in the bass. Any amp that doubles down the power at 2 ohm vs 4 is fine. Also the 2.4 have a bit of a rise in the treble on axis so try to use as little toe in as needed to get a good center image. Thiel often recommended no toe in but you need a pretty big room for that as they are a wide dispersion speaker and reflections can be an issue.

Really they are not hard to drive. I had them on a Marantz SR5005 for a few weeks which is a $800 receiver from early 2000s?!? (I needed an HDMI input) and honestly the bass was pretty slamming, Not kidding. It was a big open room to 27’x20’. All the fine details were bad and lost in the receiver though lol

I tried them with a few classD amps which I would not recommend. They were harsh in the highs and had midrange glare. Good bass though.

the best combo I personally used was in my main system on McIntosh MC462 on the 2ohm tap. It really softened up the speaker while still being dynamic. I could listen all day with no fatigue on the Mac.

At their current used prices they are a steel. When I went to replace them I demoed speakers in the $10,000 $15,000 range and had trouble bettering the old Thiels. I think their highs are a bit dated now. They lack air compared to some of the modern designs. Everything else is pretty great though.

No, I've never had a problem with the midrange drivers.  As far as I know my midrange drivers are original. I am not the original owner, and bought them from the same dealer that originally sold them when the original owner traded them in for Thiel 3.7s. When I bought them the speakers were 5 years old and in excellent condition and I’ve never had a problem with them. Prior to the Thiel 2.4s I had Thiel .5s in my main rig.
