Thiel CS1.2 vs. Ohm Walsh 2

Thanks. Any thoughts on how best to answer the power issue? Don't need earshattering volume. It'll be a tough sell to my wife to spend as it is, and to set up "huge" speakers. Telling her I was looking at amps too would probably result in my sleeping outside in the snow. Although it's a bit of a drive, they are asking only $280 for the Thiels. Hence my interest. 

Thanks again for the advice. Looks like I will have to let it go, or try the Ohms. I can't get the speakers and upgrade my receiver for an amp. It would be okay if the performance wasn't optimal, but if the sound would be fatiguing, or there could be damage to the receiver, that would be bad to say the least.

Thanks.
Any suggestions for a "low cost" power amp that would do it that I can find on the secondary marketplace as you say?  As I have said, would not have to maximize the speakers' performance, just work, and sound better than the present configuration.

Something by NAD, for example?

And I assume no need for you to see the Denon specs (i.e, power at 6 and 8 ohms, distortion etc.).  i guess I could ask Denon what the power rating would be at 4 ohms.

Fair questions.
I would think I could use the Denon as a preamp with line out. (Have to check.) I have a separate preamp for the turntable, and otherwise just play CD's and the occasional DVD.  So I would think a basic power amp would do it, esp if it reduced the cost.
   Incidentally, i looked uo the Magnepan LD, which although their budget at $650, needs more power they say.
  As for budget, not enough I am sure. Is there anything I could used or refurbished for $300? That is why I did a quick look at NAD on ebay. Used to have some NAD receivers and liked them .  I can't tell yet which are A/B, and min power necessary at 4 ohms.
   Thanks for all of your advice.
