My Vincent integrated amp has developed a problem that is going to take a few hundred dollars to fix and I don't want to take a chance on this Chi-Fi amp and then have something else crap out. I can see from pictures of the Marantz that it is made in Japan but don't know about the Yamaha. The Yamaha has a bit more power and is more versatile in terms of inputs. Looking for comments from anyone that has used either of these 2 amps as I have no place to listen to them in advance. I will get whichever one choose from Amazon due to the ease of returning if I don't like it. My Vincent amp is a tube hybrid rated at 150 watts and sounds really good but I just don't see it as being reliable. Nothing worse then sitting down getting into a listening session then it starts acting up. I primarily listen to digital via Roon and Qobuz as well as CD's with an Audiolab 6000CDT. I also have 2 turntables which the Yammy can accomodate. My speakers are Elac Carina Towers. Thanks in advance!
