Thiel CS1.2 vs. Ohm Walsh 2

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.

Yes, NAD, especially their Class A/B amps, would likely make for a more suitable match.

And if a manufacturer does not specify a 4 ohm spec the amp is likely not stable down to 4 ohms.

So are you looking for a power amp or an integrated amp?
(A basic power amp would require another component to perform the preamp chores)

And very importantly, what is your budget?

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.

Wait, isn't your Denon 80 watts per channel? If so, I would think you have enough power for the Thiel's, at least for now- and, if you don't try playing too loudly.
If you need a decent low cost amp, you could try to find an old Adcom GFA-555, but they are a bit long in the tooth.
I would suggest finding a used McCormack DNA-1. or .5. The best thing is that you can send it to SMcAudio for upgrading down the road.
A Belles Aria integrated would be another suggestion.
Unfortunately, they cost a bit more than $300, but when you move up to a high fidelity speaker, you have to get higher fidelity equipment to power it.
FWIW, I think the Denon will be fine, for now. I've driven 4 ohm speakers without issue using a receiver pf lesser caliber years ago. It sounded pretty good, too.

To use the Denon as a preamp you need a stereo variable line out.  If the line out is fixed .... it won't do. If it has a stereo pre out ... that would be best.

If the Denon is not 4 ohm stable, then the risk would be to the speakers.
When speakers ask for more power than the amp can safely deliver, then the amp clips, and speaker components overheat, literally frying the speaker and potentially damaging speaker components.

If you can stretch your budget to $399 ... then my suggestion would be to look at the Emotiva TA-100 in their BASX line.  You could buy that directly brand new from Emotiva ... and that should match up well with the Thiel CS 1.2 speakers.   And that is well suited to being used as a starter pre amp down the road.
