Pure analog system with high power

@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!

@adversamTo continue on rfnoise's promotion of Audio Research, I am going to give my whole story to emphasize how much I love their sound.  There are sooo many choices and my experience is very limited, but I am a huge fan and went through this pathway:

Classic 120 mono block amps
LS3B linestage
PH5 phono

CL120s
LS26 linestage
PH7 phono

REF 150 amp
REF 3 linestage
REF 2 phono

GSi75 integrated

The Classic 120s were my first ARC products.  I had a B&K preamp and Parasound HCA2200ii amp at the time to compare.  Those 110wpc from the ARC sounded much more full and dynamic  compared to the Parasound's 250wpc.  I picked up a 2nd HCA 2200ii and bridged them so was comparing those 750wpc to the CL120's 110wpc and they CL120s still won.  I know it is hard to believe, but they really did!  My main point thus far is to not get uber focused on specs.  That is one thing I have learned over the years is to only trust your ears.  I don't care what the damping factor or rated power is of my ARC amps...they sound amazing and have driven my low to modest efficiency speakers well(86 and 89db)

I accepted that I was a tube fan and sold the Parasound amps and listened to the CL120s for about 3 years before getting the REF 150 along with all the other upgrades you see above.  While the REF 150 sounded glorious, I got a GSi75 that popped up for a good price.  I thought what the heck, if I don't like it I will resell.  Well, I love it and I sold all the separates.  They don't pop up too often and that alone would be out of your stated 'amp' budget.  The GSi75 has a great phono and DAC so depending on your ability to check one out, you may be able to sell other gear to consider an all-in-one integrated.  ARC also has the VSi75 that is a standard integrated with no phono nor DAC.  I love ARC's sound and would encourage you to audition.  There is rumor of a new integrated in their lineup that is customizable regarding plug-ins like the phono and DAC.  This would need time to settle into the used market to be feasible so just an FYI.

While I love my current system I am always curious about other components and lately I have really wanted to hear one of Mark Levinson's latest integrated amps.  Their 5805 would be in your budget used and is also an all-in-one with the phono and DAC.  Their 585.5 is more powerful and similar to my GSi75 in pricing so would need the selling of your other gear to open up your budget.  I have no idea how they sound but have been very well reviewed.

Enjoy the hunt and come back to your thread when you pull the trigger.
