Newly acquired Thiel CS2 speaker.....HELP?


Configuration comments/suggestions?

I have a pair of Thiel CS2 speakers that I just acquired from a neighbor. I connected them to my existing system as follows:

·         Denon AVR-1312 5.1-Channel A/V Receiver (WiFi music pre-out to NAD). I am considering replacing this with a Yamaha RX-V685 7.2 A/V Receiver, as I am no longer able to access the set-up menu.

·         NAD 7240 Receiver (rated at 40 watts/channel of steady-state power)

·         Sony Blue ray disc player (direct to NAD)

·         16 GA speaker wire.

I was REALLY impressed at how much better the Thiel’s sounded than my old college tower speakers, specifically when listening to vocals, acoustic guitar and classical e.g. Vivaldi.

I also acquired a DBX BX-3mkII from same neighbor. He did not use this amp, so not sure about it other than these specifications:

   o   Power output                 (RMS, 20 Hz~20kHz)

   o   2 Channel driven             300W x 2 (THD<0.01%)

   o   Power Output (Dynamic, IHF A-202)

   o   Single mode                    80 W per channel (8 ohms)

   o   Bridge (BTL) Mode         550 W per channel (8 ohms)

   o   Load impedance               2~6 ohms, 6~16 ohms Switchable

Currently, I do not plan on running any other speakers off of the DBX.

Here is what I have in mind:

Yamaha A/V receiver has a zone 2 pre-out that will allow me to stream music to the DBX without including the surround sound. It would also allow me to include the DBX and Thiel’s (zone 2) with surround (zone 1) when watching movies, by switching to zones 1 & 2.

Based on the DBX manual, I may want to run 6~16 ohm Bridged mode?

Thanks all, for the responses!
I've been reading multiple sources of information about amplifier to speaker compatibility and while I have learned plenty, I'm still a bit unsure how to proceed with making the optimal connection between the DBX amplifier and the CS2's (only).   It seems that even if the amp puts out much more power than is needed, I'll be fine as long as I'm not trying to entertain the neighbors down the street.  I agree with unsound, with regard to being able shoot for optimal impedance settings (given the CS2 data) and avoiding a "too hot" situation.  My first thought was to use the 2 channel BTL, but I have to admit that I'm not too comfortable with that connection ("too hot") and don't think the manual is clearly presenting the best option, given my level of experience.  Would anyone be willing to give advice (with explanation) on how best to configure the channel mode and wire connection?   I attached a link to the DBX manual below.

^By “...too hot...”, I meant to elevated high frequency or bright sounding.
