McIntosh- Sweetest, Smoothest sounding Solid State ?

i currently have a parasound a21+ driven by a cary audio SLP 05 tube preamp.  
i liked the parasound at first but after 7 months or so it is sounding slightly sibilant and less refined.  
@riaa   rogue makes great sounding products and i recommend them whenever they are in the range of a recommendation request.  
i have ventured into tube preamp solid state amp and i am not a fan of the tube class D hybrid sound.  

Here we go again, all Mac haters to the front and start bashing away! Give it a rest guys, this is getting old and pathetic!

sid42,
It's a popular pastime. I'm surprised that George hasn't weighed in yet to say how the autoformers are there to "fix" a defective design.

They do fix a design flaw, poor reactive speaker loads from bizarro drivers…

Give the new Krell K300i intergrated a look, enjoy mine with Monitor Audio PL300 ii.
