Warmer sounding Solid State

@bpoletti Warmer sounding because my speakers have a bit of gain in the upper registers.  I am looking for a power option that will balance them out.

You using any thing to clean the power feeding your equipment?

An expert amp designer recently noted here someplace that harsh speaker treble with SS amps is simply the nature of transistors...I've owned SS amps that weren't harsh particularly, but the tube amps I've owned and prefer these days have a more natural treble response. 

I would not say the Marantz is the end all sound that you want to achieve. There are much better sounding integrated amps out there that are warm sounding, like from Classe and Mcintosh which are excellent companies. There are also  natural sounding integrated amps from Hegel that sound just right. You might want to look at a nice tube integrated that has enough power to drive your speakers, like the rogue Cronus magnum with the kt120 tubes. Or you might want to look at the new sprout100 from ps audio for $599.
i have owned or still own all of these products mentioned above and I have enjoyed/or still enjoy them.

Almost any Pass Labs  integrated amp will solve your problem.
About the best SS you can get with moving to tubes.
