Any advice on Ayon scorpio integrates?

freediver 

Thank you for your advice! I thought same of Ayon at first, but their scorpio is in the $3,500
 range so thought funny there are not much mentioning on it..  PL probably seems to be the most failsafe choice, while as I dig into other options, beginning to lean toward models with more unique designs. My speakers are 83.5db,
very much limits the tube amp options..If without  thinking of my speakers, my preference is class A SET (my current is a cheap 8wpc 6l6gc,I get a touch of it but not a good match).  I really want to stay with SET but not much options out there with my primary search, and I started to consider pushpulls. That is how I came to be interested on Scorpio with class A Pentode. 

Mastersound, class A para single 35wpc sure is attractive! I see similarity in design to Unison research (not the structure but in the similar logo fonts) If I was a real setereophile, this may be a no brainer with that audio mart price.  Boxed Italian design is nice but this may be a design I may seek for later in my journey but for now, I miss the open chassis design with tube show off. 

The Icon also is a new  name to me. Class A, pentode/triode, 28/20wpc, enabling SE drive using KT150,,, and with open chassis! I understood this specifically designed with KT150 and not that one can play with tube exchange but this is interesting! I may need to do a deeper learning on this Icon.

Thank you for your advice too. Raven seems interesting but probably I cannot wait. Quicksilver, I did a superficial search before but not in depth up to now. I thought it was more expensive but around $2000 is a nice price range. The “separate mono block like” attracts me but I may need to do more learning on this; it looks like it is a class AB push pull and a closed box design. class AB seems to have a more dynamism of suppose front to rear sound stage width, power on classic orchestra playback than a class A single being more on the spot tube sexy sound with realism. 

It may be more attractive to me if was a open chassis (why the integrated is almost the only closed box among Quicksilver), but the closed box do have an weight on the look, probably I may get to that taste point later. 

As you may see from my unorganized comment that I am actually still at my learning stage. 
again, thank you for your advice.

That Quicksilver is only a 20 watt amp. I own the Harbeth P3 and the Quicksilver integrated would not be a good choice. BTW, I use larger Quicksilvers with the P3s. I did call Mike Sanders about the QS integrated paired with the P3 and he told me that 20 watts will not cut it!

Yes this amp was originally built by the owner of Icon as an end game amp.I've run pretty much every power tube available,in every Class configuration they come in & was confidant that Pure Class A,Single Ended Pentode is perfect for my musical tastes & speakers(Harbeth M30.1)...It's so sweet to be running Ultralinear for hard driving classic rock/Chicago Blues & then switch to Triode Mode for Classical/New Age/Jazz..I'm past the desire to tube roll as well so another reason I went with this amp,EVERY aspect is completely optimized for the KT150..

Yes  Cayin are made at the same factory as PrimaLuna. I have one half the price.
