Anyone Recently Change to Class D power?

Am not a huge fan of Rotel or Parasound personally.  I find they are both competent but unexciting amps.  They need exciting speakers to be at their best.  
This is obviously a matter of taste.  

I think the C298 is more dynamic.  It is not in upper echelon like the Chords or AVMs but at $2K, I love it.  Would be my first choice in that price range if it was with neutral to slightly bright speakers.

I have had a variety of units in recently that are Class D (Rogue, AVM, Canor, NAD) or unspecified with switching power supply (Chord) in case my benchmarks which are a pair of Art Audio Opus 4s which are Class A KT88 based monos.

Each has pros and cons.  In terms of pure refinement, The Chord monos I had here were spectacular but are brighter.  Tremendous detail and a big soundstage. Superb separation of instruments and one of the most detailed amps I have heard.   Speaker pairing is critical and a warmer speaker is required to get the most out of them.  With the wrong speakers, you be quite unhappy.  The Chord Ultima 6 power amp would be in this range.

I have the C298 here now and have heard the M33.  The M33s excellence stems from its room correction like Lyndorf and Anthem.  The C298 is a very good sounding amp but is not in the same league as Chord.  I have been told it is essentially the same amp module that is in the M33.  These are Purifi based. 
Canor AI 2.10 has a 6922 based input stage.  I spent the afternoon listening to this.  It ever so slightly lacks the separation of the much pricier Opus 4s.  But it is quiet and dynamic.  That being said, I have the crappy stock tubes in and am waiting on options to roll in.  I have three pairs on order.  This a Hypex module with a tube input stage.  For $4k, it is nice.  
AVM A5.2 is also Hypex based with a tube input stage.  This is a big, powerful amp that is detailed and dynamic.  Sounded cold and analytic out of the box but gets warmer and more engaging very quickly.  They use a proprietary tube that can’t be rolled but sounds very, very good.  This is definitely the closest to my Opus 4s and I am bringing one in.  Also is nice because it has optional cards that can be added for DAC, phono stage and FM tuner. At $6500 for the base model, it is in the same league as Chord in terms of price.  
Finally, the Rogue Hydra which is also a Hypex module with tube input stage.  Relatively inexpensive with a 12AU7 tube used in the input stage.  Like the Canor, this falls a hair short in terms of detail and separation of instruments but at $3K???

I hear very good things about the Jeff Rowland amps and I am sure there are others that are incredible.  
I am a dealer for Chord, AVM, NAD and Canor.  I have no affiliation with Rogue, Langford, Anthem or Jeff Rowland

Safety????  You would think high current amps that run ultra hot would be far less safe than lower current amps that are cool.  You can debate whether they sound good, but I don't think there is any criticism in terms of safety of Class Ds.  

What speakers are you running?  Your going to get very different recommendations for Harbeth or Vandersteen vs Kef or Magico.
