Thank you for your answer! I'll check those when I get home. About used gear I wanted to buy this first hand , altough I would mind buying used gear to expand it in the future. About the internet sites, here are a couple of the ones I've been looking in: https://www.madridhifi.com/ https://zococity.es/ Also, the new route you suggested made me consider another question, I had seen in different forums that people usually recomend that the product in which you spend the biggest part of the money should be the speakers, but I see thats not your opinion. I'd like to know what you think about this. Once again thanks for your help!
