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!

@smrex13 thanks again that' s a very nice info... could you mention some integrated or power amp which played your vinyls in a very satisfying way? that's exactly the recommendation i need as basically i play just vinyls as you
@adversam I think you're making a good choice by considering an integrated amp with high power - that approach will work well with Magnepans, Harbeths, and most other speakers as well.  It's a great foundation for whatever you decide to do down the road. 

I won't pretend to know the used market at your price point.  As far as new integrated amps, here are a few companies that make products that are generally well regarded by reviewers and people who have owned them long term:

-Parasound:  HINT 6 - Yes, you're paying for a bunch of other stuff (dac, phono stage), but by all accounts it's a very good integrated amp even if you aren't using its other features.

-Musical Fidelity:  M6si - This one is a powerhouse - 220wpc.  For some reason, MF doesn't spec their input sensitivity, so you might want to do some research to see if it's a good match.  The M5si is also well regarded and still has 150wpc into 8 ohms.

-Bryston - they only make one integrated amp now, and it's beyond your budget.  But Bryston gear lasts forever, so the used market might be an option here.

Hegel - Many people rave about Hegel.  I have tried two of their integrated amps (H80 and H200) over the years.  Neither worked well for me, but I'm in the minority.  In hindsight, I wonder if they have a lower input sensitivity, as they sounded distant and lacked dynamics.  To be fair, I haven't heard any of their more recent models.

Those are just some quick thoughts.  Ideally, you'd be able to hear them in your own system.  But, again, if you get a well designed, high powered integrated amp, then you can have fun experimenting with phono stages (tubed and ss), different cartridges, turntables, tonearms, and speakers, all of which likely will have a far greater impact on the sound of your system. 

Cheers,

@smrex13 thank you again for your reply, you're really giving me great inputs! indeed regarding the integrated i m between the hint6 and the m6si... following your previous comment i also went to check the input sensibility but i confirm you that for m6si there' s no info... i'm also thinking of odyssey's amps but first need to find out about eventual shipping to eu. I have a last question for you, coming back to Parasound's gears... as an alternative to the Hint6 I'm seriously considering an Halo A21 power amp, maybe with a Schiit Freya as a preamp... Did you have any experience with the A21? Could it be a good match playing music with a turntable? Thanks again for your precious help:)
I understand that Magnepan uses Bryston for reference electronics. But could be wrong.
@adversam I've heard good things about Odyssey amps, but I don't have experience with them.  Rather than asking whether an amp is a good match for vinyl, I think the question is more whether an amp will be a good match with your speakers.  With respect to the Parasound A21 - yes, it will certainly drive your speakers well.  

And if you are looking at separates rather than an integrated amp, the preamp is likely to have more impact on the overall sound of your system than the amp will (assuming that the amp has enough power for your speakers, of course). 

In any event, if you are trying to get your vinyl system to sound as good as possible, I would probably worry least about the power amp - Bryston, Odyssey, Parasound, Musical Fidelity, etc. all make amps that will drive your speakers with good control and power.  It's far more important to get the cartridge, tonearm, turntable, and phono preamp working together well (and the preamp if you are going with separates). 

At least that's my opinion.  Others may differ, which is why this hobby is fun!

Cheers, Scott
