Thiel 1.6 vs. 2.4 vs. 3.6 using NAD c372

The big question is do you think you might upgrade your amp in the future. If that's the liklihood, I would recommend the 2.4's. I have a set of 2.4's and 1.6's. The 2.4's are sweet with an adequate setup. With an X250 driving them, they have probably been the favorite speakers I've had, and I've had some decent speakers over the years. My wife has taken control of the 1.6's driven by a Denon receiver and DVD player and that's not bad. I had them on an X3 at one time and they sounded very good. But, I couldn't imagine driving the 2.4's with a C372 long term. And I'm thinking hard about getting a C372 for a third system with Quad 22L's.

when it comes to thiels speakers , I own the top of the line
thiels 5i , Krell amp is the best. matched it with a tube
preamp. you will never look back and just enjoy the music.
However the thiels is not bright , it just take time to match
it. the 3.6 is very good. get it if you have a chance.

Thanks to everyone who has replied to my thread. I wound up getting a previously owned Krell 300iL integrated amp with 200wpc. This was more than I originally set out to spend, but I think the investment will be worth it to sufficiently drive the speakers. I am now looking for the Thiel 2.4 speakers at a decent price and in good condition. Then I will need to figure out which front loading CD player to buy. I've heard the NAD c542 is pretty decent. Thanks again!

I have a pair of Thiel CS 2.4's I am very happy usuing a bryston 3b sst poweramp and bp25 pre. Vinyl sounds alive, Imaging is amazing "wall to wall"
I have a similer sized room as you, a little bit smaller. Placement of speakers about 3 feet from each wall, about 6 feet apart. I am sitting about 8 feet away from the speakers, enough distance for the drivers to integrate.
I highly suggest the 2.4s
3.6 requires lots of space and a BEEFY amp, my bryston would be the bare minimum. the 1.6's lack the great bass the 2.4s have.

Good luck...

I own the 1.6's and am extremely happy with them. Their midrange and highs are excellent and very detailed. The bass is tight and accurate, but does not extend into the low end. I do have a subwoofer integrated into my system and have been able to match it very well with the 1.6 to get that extended bass response.

That being said, the 2.4's are superb. The 3.6's are also excellent speakers that have been a staple in Thiel's lineup for many, many, years and are just now being replaced by the 3.7's which are not officially released yet.

Thiel speakers require good quality amplification to sound their best. I originally drove my 1.6's with a Denon AVR-3300 receiver which surprisingly worked quite well. The downside was that the amp in the receiver tended to get hot and the sound was a bit thin, but it did work. I ended up buying a used Acurus 100x3 amplifier and that has made all the difference in the world with these speakers.

As to why the 3.6's have dropped into the same range as the 1.6's on the used market....I think it's because the 3.6 is now discontinued due to the imminent arrival of the 3.7, and also that the 3.6 uses older driver technology as compared to the rest of the line. The 1.6 is a current product still.
