Need recommendation for amplifier

rvpiano,
That was fast! Good choice buying the Red Dragon M-500 monos, congrats.
Yes, the 45-day tryout period is very good but I seriously doubt you’ll want to return them. Plenty of clean power and high damping factor should enable your DQ 20 speakers to really sound their best.
The combo of your CJ tube preamp with a very good pair of very neutral class D monos will allow your system sound to be influenced primarily by your preamp and sources so I hope you’re currently very satisfied with the quality of both the CJ and your sources. Your new Red Dragon amps do not add anything to the signal to compensate for subpar recordings, cabling or upstream components.
My D-Sonic M-600 monos are also very neutral and they enabled me to much more easily distinguish how any changes I made in my upstream components or interconnects/power cabling affected my system’s overall sound. This aso included tube swaps/upgrades I made to my former VTL 2.5L preamp.

Enjoy,
Tim

Tim,

I was anxious to get something decent after suffering through the the repairs of the NuForce.  I’m hoping the technician will buy them back from me.  He’ll be able to use them more than me.  I won’t hold my breath though.

Thanks again for the recommendation. 
Thats exactly what I’m looking for, a neutral amp.
I do have excellent upstream components, so hopefully this will be a great match.

rvpiano,

     Glad to help and hope everything works out great for you.   I actually almost bought a pair of the Red Dragon M-500 but they were out of stock on the black models.  I think the M-500  and D-Sonic M-600 both are very neutral amps even though they utilize different class D power modules, the D-Sonic use the newer Pascal modules and I believe the Red Dragon use the latest Ice modules.
    I'm almost certain you're really going to like them.  Plus, the red dragon symbol that lights up on the faceplates is very cool.
 Enjoy,
   Tim

Check out these Van Alstine amps. Dahlquist sound nice with mos-fet amps!

I see that you already ordered Red Dragons...I’m in need of new amplification too. Integrated, or separates. Was considering Rogue. Also looked at Schiit. Now, I’m looking hard at the Cary SL-100 Pre and SA200.2 Amp. They’re on sale for a few more days direct from Cary.
