Ayon's "Scorpio" tube imtegrated amp vs PrimaLuna Dialogue Premium tube integrated??.

I have considered trying a tube integrated amp. The Prima Luna Prologue Premium has received numerous positive testimonials regarding its sound quality and is considered a bargain at $2399.  Ayon’s new "Scorpian" tube integrated  is more expensive at $4200,  supposedly offers excellent sound quality, but has not gathered many press reviews. .

 Is  anyone familiar with these products??  Are they  reliable over the long haul?? and if so, can either amp  effectively drive any speaker load, including Golden Ear Technology model 7 or the larger model 5.  Or have any problems driving Magneplanar .7 speaker, or any of the Martin Logan speakers.  Thank you  

 Thank you for reply and comments. Unfortunately, I forgot this thread because I changed the 2 standard output tubes in Rogue Sphinx integrated to Mullards 4003 CV on the advice of another member.  They did make a difference  in overall clarity; however, at times. the bass seems less controlled and solid.  In addition, the sound is somewhat forward compared to standard tubed Rogue. At times, and from session to session, the sound quality is not consistent.  However, there can be a ton of other factors causing this.
Keep in mind that  the Scorpio will be upgraded in a couple months ....and your integrated dumps in value.Besides I own Primaluna in a second system and if your buying Chinese ..Primaluna
I've also been considering the PrimaLuna, but I'm also concerned about bass response. My Salk Audio HT2-TL's go down to 34hz, and my solid state Caimbridge Audio 840A V2 takes them there with no issues. I really don't want to give up any bass extension, tenacity, or impact/slam. Can you guys help reassure me that I'll be in good shape going to the PrimaLuna Diologe Premium? Do I have to get the HP model? Will it still be engaging at low level late night listening?
I saw this older thread. I am thinking of a Primaluna integrated myself. I’m also seeing some new Ayon Scorpios offered here on ag by their us distributer USA Tube Audio for $3500 or so ( the scorpios are not 60 watts per channel like listing says). Anyway, I know everyone raves about Kevin Deal. 
@aberyclark, personally I would lean toward a Leben CS-600 which can be found in good shape 2nd hand around your budget, unless you need inefficient speakers. That amp looks gorgeous & has a very good headphone amp which is a bonus - http://lebenhifi.com/products/cs600.html
