Driving a Thiel


I'm looking at purchasing some of the discontinued floorstanding Thiel Models (CS .5, 1.5 and 2.3)and was wondering whether my 120 Watt Marantz SR 8200 receiver has enough power to drive these speakers. I'm not playing anything loud but other threads about appropriate amps and so forth concerned me.

Thanks for all the help!

Hevac1...my point is the Thiels don't dip down to 1ohm. The Stereophile measurements on the Thiel 2.4 show the min dip of 2.7ohms at 600Hz and for most of the frequency spectrum the Thiels stayed in between 3 and 4 ohms. In any case, i agree with you that the Thiels do need high quality power and a lot of it and the OPs receiver will not drive them properly. By the way, every time i check out your system, I am impressed. Nicely done.
It is NOT impedance but a combination of low impedance and a high phase angle which defines a bad load.

Even a mediocre amp will drive a resistor. Some even at 3 ohms or MAYBE even lower.
However, throw in a highly reactive load and there you go.

None of the above links are to the Thiel models asked about, but certainly indicate a design philosophy which requires a first rate amp which can maintain into large phase angle loads.
Good hunting.
All Thiel's respond poorly to mid-fi amplification. I know because I ran several receivers and seperates such as Carver and Adcom, searching for a low cost amp for my CS3.5s. They just don't cut it. The amps mentioned by others are no-brainers from a pure quality standpoint, but come at a steep price of entry. You will need to spend at least $600 for something worthwhile. At that price, you can get a used Odyssey Stratos. That will keep you happy for a while, no doubt about it.
Hello smata67,

I still have the Odyssey Stratos Plus but trust me with my Thiel 2.4 it doesn't sound half than my Parasound Halo JC1's do!
IMHO to drive Thiels 2.4 two monoblocks like JC1's are just a good starting point.
On the 2.4 brochure there is a black&white picture of the 2.4 tested by Thiel and "strangely" close to the speakers there are two Mark Levinson 33H amps.. why? :)
because they want to sell the speakers to testosterone imbued customers like yourself :-)
