See what happens when you ask a simple question on this site Narciso? It's typical so don't feel too bad! I like Output Transformer Less (OTL) amplifiers matched with the proper speaker. If you are not familiar with these and you are new at this I'm not too sure you would want to start there, something simpler perhaps. The bottom line is you might want to supply a bit more information in your listening tastes and preferences, room size etc. If you are new to this it is imperative that you go out and listen to some systems to get a better idea of what might float your boat. No one here is going to satisfactorily answer your question, you picked the wrong place. You are most likely going to get overwhelmed with the variety of responses. Listening is the best way. Unfortunately there are few shortcuts unless you just want to put together a simple system that is musically satisfying. This is where a reputable dealer can help. Have you seeked one out to help you? Probably a good idea to do that first.
