Pure analog system with high power


Dear Hifi lovers, I introduce myself, I'm new to this forum. 
I need your marvellous experience in order to choose my next gear. I currently have a Rega Brio amp driving a pair of Wharfedale Evo 4.2 and I'm looking for a big step up, starting for now from the amp.
I am a vinyl lover, I basically play just lps. I also added a Rega Aria phono stage.
Now what I'm looking for is a kind of purist's solution, don't need to pay for dacs, or particolar digital inputs or functions. I want an integrated, or separated amp+pre is also well appreciated, capable of at least 150W in 8 ohm / 250W in 4 ohm as sooner or later I'll buy for sure some Magnepans, maybe the .7, or anyway some Harbeth's. My aim is to get the best money value for my purpouses, that's why I was mentioning a pure analogue solution. Anyway I accept also recommendations based on gears with dacs or digital inputs as that's the market now. Prefer new stuff but also used is fine. Budget is around 3.500/4.000 dollars. Thanks in advance to all people willing to share some knowledge and sorry if something wasn't clear, you can ask me any kind of questions!

I went w/ 120v since I’m in the US. I chose the KT88s and the standard preamp tubes which IMO sound amazing.  I’m in no rush to tube roll the preamp section but will eventually out of curiosity.  I tried some el34’s power tubes but I missed the bass and dynamics of the KT88’s, but they were incredible for jazz and vocals.  Also remember I’m using 85db speakers, you may fall in love w el34s.  I want to try KT77s next to see what they are like.  That’s the nice thing about tubes, you can tweak the sound in meaningful ways without purchasing all new gear.  Well I guess Tubes are new gear.  It also has a triode/ultra linear switch on the remote which has a dramatic effect on the sound. Triode is a little softer with better separation of instruments and ultra linear sounds more powerful and brings the vocals forward. These are not subtle audiophile differences either, your friends and family members will notice. It takes about 6 weeks or so for delivery but that should provide enough time to for you figure out what tubes to try.  
So many of my preconceived opinions on tubes were wrong (lack of detail, lack of bass, only for sensitive speakers) I just wish I hadn’t waited so long to try them. 
I concur with hshifi regarding the 'right amp' requiring the appropriate current and wattage not just watts.

I heard a 80 watt ARC amp that was driving Sonus faber Olympica IIs and I was shocked at the punch and bass coming from a '80 watt' amp.  It certainly seemed to have the same punch and impact of my 300 watt amp at home.

Therefore, auditioning and/or home trials are critical.

willsenton is made in china too ... why would you consider?

otoh - odyssey is ’made’ in indiana, usa but using china made components, casing, wiring, transformer, is that better?

best wishes on your search, hope you find what pleases you...

One word of caution in a vinyl only system - pay careful attention to the input sensitivity of the integrated amps that you are considering.  In my analog system, I tried several different integrated amps, and some of them sounded dull and lifeless (which contradicted reviews and owners' experiences).  At times it was baffling - I would sit there listening and think, "This is the amp people have been raving about?"  After some investigation, I discovered that integrated amps with a low input sensitivity did not work well in my system.  The lower output voltage of a phono stage (compared to digital sources) can't drive some integrated amps to full power.  It was a good (but needlessly expensive) learning experience.

Cheers,

@jjss49 Willsenton is a chinese product, Hegel is a norwegian company which moved to China part of the production and that's what i find a bit of a different concept, including the use of china made components which can actually have good quality... Anyway the Hegel was on my list and i'll test it because i'm very curious after hearing all the favorauble reviews... of course if i fall in love with the sound I ll go against my principles, even i still dislike their policies
