Pure analog system with high power

@perdakin thanks for your feedback... could be either tube or solid state without an6 kind of dac or digital input... very easy stuff regarding the specs as i just needto play lps or cds... do you have any favourite combination to recommend? regarding magnepans it' something i'd like to try sooner or later but after the amp i could also buy something totally different, especially if i get good ideas to try

@adversam,

The Odyssey is an excellent choice.  I owned Odyssey for many years and it mated well with many different preamps.  Although I have moved on to more expensive gear, I still kick myself for selling it.  Yup, it was that good. 

Well if you are starting with an amp you really must try tubes and your current speakers are pretty tube friendly. They have a certain realism in the way they make sound I haven’t been able to find as easily in SS gear.  I personally like push pull integrated amps.  With an integrated it’s easier to resell, no issues w pre/power synergy, and some push pull designs have enough juice for low efficiency speakers (though probably not Maggie’s).
I’m not sure what your local market looks like, but I love my Willsenton R8. Due to the backlog in manufacturing the resale prices are pretty close to new, and yes they will sell on the used market nearly immediately, which should tell you something.  I’d order one direct and if you don’t like it, you’ll find plenty of takers second hand. Otherwise try and find a Prima Luna or another highly popular tube amp manufacturer.  
I pair it with Dynaudio Contours which is actually an excellent match for a well built tube amp, especially with kt88 tubes. I’ve had monster SS amps in my system and the Willsenton gives up little in the bass department while offering wonderfully natural mids and highs. The Willsenton is almost 70lbs though, the transformers are massive which probably has something to do with it being speaker friendly. I use mine in triode mode.  It’s a holographic, natural, meaty sound with all the sizzle and snap you could ask for. 

@perkadin thanks, i've seen some reviews about the Willsenton R8 and everybody seems to be in love with it... I was checking the seller's page... did you choose the 240 voltage? Sorry for the silly question but i have zero experience with tubes

Hello,
The one killer in all of this is the Maggie’s. They need the right amp to drive them. Not just power but damping factor. I would go with a Hegel 120. I know it seems low at 75watts. The main thing is the damping factor. This amp will push your Maggie’s very well. They are on your side of the pond. They are $3000 usd. You can use the rest on the sub you will need.  REL is very fast and a great match for your Maggie’s. It will have some digital built in so you can explore a little to decide what vinyl you want to buy. You are right about the Rogue Chronus Magnum. I thought it was 60 watts not 100. Still, more than enough power. If you want to try to work with a dealer in the states the local store in the Chicagoland area is a dealer. Maybe you can come to a deal with shipping. https://holmaudio.com/You should call and work out a deal. Plus, this Rogue is built very well and is the perfect sweet spot for all speakers.
