Before I purchase

First, there are a ton of great options in this area, so why just these two?  Second, before anyone here could give you even any semi-useful advice you need to share what's important to you from a sound reproduction standpoint and/or what you're looking to improve upon.  Third, you need to let us know what your other components are to see what may or may not be suitable, especially speakers but everything else helps too.  Because as we all know, the final result is ALWAYS the combined product of EACH individual component and how they interact (the magic sauce).  The only two absolutes I've ever believed in this wonderful, awful hobby are that EVERY link in the chain matters at some level, and that the chain is only as strong as the weakest link.  So if you share what's important to you, what your ultimate personal goals are, the equipment you currently have, and I should add VERY importantly your room characteristics, the better recommendations you'll get on how to complete your own personal and optimal audiophile chain.  Bottom line -- the more you give here the better information you'll get.  At this point you've given us is, well, virtually nothing.  The good news is that there are many, many very experienced people here who are literally aching to help point you in the right direction.  The only thing they need is a fairly accurate map.  That's on you. 

Can you demo both, and just pay to ship one back?

That may  be  best, to determine what agrees  with your ears.

Comparing the 2, they differ in how the tubes operate.

They will sound different. They have different power tubes as well.

Not an apples to apples comparison.

The fact you  have a PL  dealer local is  helpful.

Yes I am thinking more that way of local with Prima Luna and will go listen to one this week...I guess the reason I ask this question I saw out west they had the Ayon Scorpio with 1k off list and sparked my interest and was wondering about quality of unit to Prima Luna...But no the Ayon I would not hear and would have to ask about returning if not happy .It is USA Tube Audio if I. purchased .
Any one purchased from USATubeAudio? And good or bad??
I have a chance to get used Cayin 88 used but it is a 7 hour round trip. The person will not send it to me unless I hear it.. But I know it will not sound anything in his place vs mine.. I am using Definitive Technology BP 8080ST bi polar speakers in hard wood floor room that is 13 X 23.
I have been using a Marantz SR8002 receiver.. And I know from what you all say that tubes make differences in units so know there is a way to change the sound of tube amps...I am searching for a less sharp sound and softer with my hearing...

Joe,
I own a PrimaLunaDialogue Integrated....it’s the best tube rig over the three I’ve previously owned. Good warranty and I’d describe the sound as full, spacious and detailed with the stock tubes.There is no "sharpness."  I have not felt the urge to "roll" or swap out tubes. I don't know your speakers power needs but tube power always seemed to produce more perceived power than it’s rating when I compared to the same solid state numbers. If you go audition and have been used to solid state, the change in sonic presentation may surprise you. BTW, USA Tube Audio in Arizona is the primary importer/distributor for Ayon products. Ayons are real eye candy if you like chrome. Don’t know how they sound.

Larry do you have the Dialogue Premium or Dialogue Premium HP ??

I purchased the Prima Luna premium hp about 6 months ago. I have been extremely happy with my choice. I also am content with the tubes, build quality is fantastic, the remote is solid like a brick. Nothing cheap about this unit. I thought the price point was very reasonable for the results. It has made my Focal Electra1028’s sing. 

Thank You..Will go to Prima Luna Dealer this week after the snow moves out.. I just saw a article on Raven Audio out of Texas .
They have a Nighthawk and Blackhawk 3k to 4k integrated amps and they have at home trial for 45 days on their site..
To much to chose from and to many reviews. I think a person like me gets a tube amp and it has just little better definition /smoothness I will be pleased and thankful with hearing issues I have to be just thankful at 67 to even hear what I do at this age..Working in Fabrication shop 41 yrs.
Thank You will let you know what I do in time..

I don't usually steer people to reviews but one of the reviewers I like most Christian Punter at Hifi Advice has extensively reviewed both Ayon and Primaluna. Spoiler he likes them both very much and well worth reading here is a link to the site.

Bring your speakers! I home demo'd a PrimaLuna HP integrated and an Anthem STR. The PL sounded great, but couldn't power my hungry speakers. The Anthem had totally different sound. Powerful, but flat compared to the PrimaLuna. 

It's a total pain, but bring in your gear and compare and contrast. Better yet, bring as many home as you can and listen in your own room. You will be amazed at how different each unit sounds. 

Joe, I have thePL Dialogue Premium, with 4- EL34 power tubes, I didn't need the extra beef of the HP. My speakers too have self powered woofers....the non HP version should have plenty of power for your 8 ohm speakers. Your local PL dealer should be able to tell you if this is a good match with your speakers.
