McIntosh- Sweetest, Smoothest sounding Solid State ?

Check Point Charlie is a Con-man As much as I like the Gear... he is not to be trusted... wouldn’t get involved in a dealer issue.. AT ALL When he Should have

I was effectively ripped off by a mcintosh dealer

Seeing as my filter broke partying  Tom Passafuime, House of High fidelity and Mcintosh are ALL guilty of ripping me off for IT work.
 

McIntosh does have a,nice relaxing sound when needed,,not the best for rock or metal, but depends on the,speakers and source. 
 

they are a great quality product. Out of my league, but have auditioned so many over the years!  They are great! Always wanted the 1000W. MOnos!

   Plus that blue glow is mesmerizing and relaxing.

 Won’t ever be in my wheelhouse, but there is a lot of as good and better out there!

"It may to you"

I have MC 302 and am upgrading (in my opinion) to Moon M400 amps.  I've upgraded my C2600 preamp to Moon 390 (again, my opinion).

My McIntosh system always sounded good to me and that's the feedback I heard from others.  My shift is a result of a need for more power and comparing McIntosh with Moon - I didn't compare to Moon when I upgraded from NAD.

Therefore, "it may to you" is my response.  And as long as you like how it sounds and it pulls you into to listen more and get more enjoyment go for it!

If you want to look at other brands there are many out there and they sound 'different' sometimes.  And sometimes different isn't good or bad until you start assessing how it makes you feel.

I was never disappointed with my SS Mac gear - if not for wanting more power and testing other options I would have been very happy to keep it.

Who cares?  
Transparent is the goal.

It is, but if the amp is not smooth that is an indication of distortion. Its hardly being transparent at that point. 

This is only slightly off topic, but what sonic coloration does an autotransformer impose on a McIntosh power amplifier?

My understanding is that its there to reduce coloration since the amp makes less distortion because the autoformer loads the amp at a higher impedance than that of the speaker. All amps make greater distortion into lower impedances; conversely less distortion into higher impedances. This is a simple albeit expensive way of making the amp sound smoother and more relaxed and its doing it by reducing distortion.

Its relaxed character in the highs isn't a frequency response error- its that way because of less audible higher ordered harmonics. The ear uses the higher orders to sense sound pressure and so is keenly sensitive to them; it also assigns a tonality to all forms of distortion and the higher orders are assigned 'bright' and 'harsh'. So reducing them results in smoother sound.

“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.”

I’ve had a Parasound A23+ for well over a year now and it’s not sibilant at all and I do find it refined in my professionally calibrated system. I tried a high end Class D Gan amp recently, and the Parasound was light years better in every way. Perhaps something else in your chain isn’t up to par, misadjusted or maybe room acoustics are bad.
