Hi, Itamar.
Rollo (Charles) is right to ask about your budget. We could offer 25 suggestions, but if they're all too expensive, it would be a wasted effort.
That said, I have found with my Adelphos:
1. My Nuprime IDA-8 ($995 USD) does a decent job of powering them. The IDA-8 is 100W/ch, has a DAC and preamp all in one compact unit. It's a keeper for my office system. However, my speakers do not shine with this amp. They sound okay though.
2. Folsom's Little Chip amp (forget how many watts...25/ch??). My Apelphos sound almost tube-like when they're powered by this amp. You buy it from Folsom (Jeremy) as a kit. It's very inexpensive. You'll still need to buy a DAC/preamp. It's very impressive for such a small amp.
3. I also own a Nuprime ST-10 amp ($1600??) (150w/ch). This is a very nice sounding amp the allows my Adelphos to shine. You'll need a separate DAC/preamp.
4. I do not own this, but a Nuprime IDA-16 has 200w/ch and a better DAC/preamp than the IDA-8 ($2000??)
5. My Don Sachs Kootenay120 KT88 tube amplifier makes my Adelphos sing in six languages and seduce the angriest neighbor. It is my 'amp to die for' ($3400). Hell, all of my speakers sound amazing powered by this amplifier. I still must pinch myself to make sure I'm not dreaming.
6. IceEdge 1200as2 amplifier (price varies, but approximately $1800 USD). Class D amp that sounds a lot like my tube amp. Up to 600w/ch! It's the wave of the future, I think. I believe there is an IceEdge 1200as2 amplifier dealer in Italy. [I'll ask a friend who knows for sure.]
Except for the IDA-16, I own all of the above mentioned amplifiers. My very first amp was a $600 Denon AVR that sounded like garbage. It didn't matter which speakers were powered by the AVR, they all sounded horrible. It was a $600 lesson on what not to do.
Good luck with your search, and have fun along the way. This is a great hobby.
