Wow, a great reply. Briefly, I am more of a music lover than a hi fi fan, but I love to listen with good sound. I rarely change my system. My first system back in the seventies consisted of a Garrard SP25 and a Metrosound 10 watts per channel amp! My XT4`s I bought a couple of years ago. Not only do they look great, they sound great, but, apparently need power! I will take a bus one day and come back the next day with a friend in his car. It is from an individual and we have been in e mail contact, he is now on holiday and not home. He is sending pictures first but assures me all is well. I will of course listen. If there is an obvious issue I will not buy, but he tells me all is as it should be apart from a couple of minor scratches, which I have seen. The price is 470 euros (he originally asked 525) but these amps rarely come on the market, specially here in Finland.
Thank you for your interest and also for your excellent use of the English language.
