Primaluna EVO 300/400 Preamplifier owners - let's hear from you
@rzrompThanks for the feedback. Your full tube setup sounds enticing!How is the volume control via remote? Does it do incremental adjustments well? What kind of music do you listen to mostly? 
Impressions: $1k-$2k integrated amps
I would add the Schiit Ragnarok and Musical Fidelity M5si to your list. 
Separates to tube integrated
You can also look at Vincent audio for a Hybrid design. The one below is really well reviewed. It's class A solid state with a tube preamp. https://www.vincent-tac.de/en/product-lines/tubeline/sv-700.html  
Separates to tube integrated
Primaluna EVO 300/400 is a really good choice. You could save some change and get the previous rev Dialogue Premium Integrated. Luxman also has an Integrated LX-580. The Rogue Audio gets good reviews as well. I would just figure out what kind of s... 
Whats playing on your system today?
My Morning Jacket - Waterfall IIThis album is just so lush and dynamic. Great folk rock with a psychedelic leaning. 
I am looking for help selecting an amplifier to match my Revel F228Be speakers.
You can get a Luxman 509x for 7K used. Should be pretty smooth in the treble. Save a few grand with the 507. 
unbeatable Class A integrated
Can't go wrong with the choices above. If you are in the US easier to find Luxman and Pass Labs. 
Optimal output range
If you look at some graphs showing power vs. distortion you will see the sweet spot for the amp when it comes to output. SS state amps generally start at lowish distortion, drop down even lower in the sweet spot, and then rise (eventually steeply)... 
Luxman 590axii vs Pass Labs int 60
@audiofoundDid you end up making a decision on the Luxman vs. Pass? 
Anthem STR or Naim Uniti Nova for Paradigm Persona 3F?
Don’t worry about the wattage. Naim amps are conservatively rated as romney80 stated. Just look at the size of the toroidal transformer inside. It’s freakin’ massive. 80 watts of good power will drive the 92db sensitive Persona 3F with ease. 
Used preamp under $400...
Definitely check out Schiit for a low cost Tube buffered preamp option. 
Any love for Musical Fidelity integrateds?
@arsh Thanks!What speakers are you powering with the KWs? Curious to also hear how much better you think the Nuvista 800 is? 
PRIMA LUNA AMPLIFIERS
The switch is for EL34 or KT-88 bias. The KT-120 & KT-150 are a whole different tube than the KT-88. The 120 & 150 use up to 25% more heater current. Unless the amp has a regulated heater supply capable of supplying the increased load, a... 
Any love for Musical Fidelity integrateds?
@arshI have a KW 500 as well since 2015. It’s a beast of an amp and sounds really good. Never had any issues with it and way more power than I would ever need. 
Anyone heard Schiit's Aegir?
@melmI agree - odd that there are not professional reviews using them in a monoblock setup.@squeak_king_77Odd indeed. But they worked well in Mono configuration otherwise? What speakers were you using?
