Pure analog system with high power

When you say pure analog system, do you mean you want a tube amp?  Also, the best value for the money in my definition would be essentially free, which is a very real possibility in high end audio. I view value a bit differently and always consider resale valuation and total Cost of ownership.  I usually aim to break even on an audio purchase.  Buy used, get reputable, reliable, easy to sell brands and your main costs will be on records and wear and tear items like tubes and needles.  Don’t waste money on expensive digital equipment (the biggest losers are always feature based products that can become obsolete, but that doesn’t sound like it will be an issue.  Spend money on speakers and amplification (but don’t go too big as shipping and placement becomes a detriment to resale). I’d also avoid niche designs like Maggie’s that work best with specific music genres and are very equipment and room dependent.  
Tips- look for popular brands and models that come up ad nauseam in the forums, find out the typical prices they sell for and be patient. If you have trouble finding it used because it sells too quick, that’s probably a winner right there.  Buying local really helps as well, you generally won’t make back shipping costs on resale.  

@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
