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!
@rfnoise thanks, looks like a great recommendation... which preamp are you using with it?

I’m using an Audio Research Corporation LS-25 MkII.
Thus far I’m pretty sold on the “tube pre/SS power” combo. Great imaging, open airy highs, and a real authoritative grip on the low end. Overall, I’d characterize the sound of the amp as being just a tad warmer than neutral.

I hate to fall into the “buy what I have” camp, but I really lucked out with this amp; The Bryston I was looking at was $2500.

Funny story... The guy I ended up buying my Legacy from turned out to be selling it BC he’d “upgraded” and actually bought the exact Bryston I’d been looking at. When we hooked up my preamp to the Legacy to audition, I looked over at him and he was shaking his head. I asked him if something was wrong and he told me that the amp he was selling me sounded better paired with my preamp than his new Bryston paired with his SS pre 😁.

Before I settled on my ARC pre, I was looking at both Audio By Van Alstine and Quicksilver Audio, but I can’t personally recommend either as I never had a chance to Audition them.

Anyway, I hope this helps. Best of luck!

Oh, here’s a link to an old listing that has a pic of the sales brochure on it.

Welcome @adversam.  You are certainly on the right track with all your choices.

Don't let that awful bully Miller put you off your course.  He is obsessed by ultra high efficiency speakers and therefore ignores 90% of speakers many of which have superlative sound quality, including panels like Magnepan.  You should also try electrostatics when your budget allows.

As to amps, like others I suggest you tap the used market.  High end solid state leviathans push out bags of watts for decades without needing service.  My Krell KRS200s, pure Class A, were built in the mid-80s.  I bought them in 1989 and had them fully serviced and re-capped just once, in 2005.  They cost £35,000 or something new.  I paid £8,000 and they still sell for that.  And wow!  they don't half look the business.  I used to be able to lift them!
You might like the A100 from Polish design studio Circle Labs if you can find one; the A200 is their flagship integrated but at a bit higher price.
