In my quest to upgrade my NAD375BEE (driving LS50’s) I thought that the answer was going to be a McIntosh integrated, either the MA6300 or the MA5200/5300. Now, my McIntosh decision was mostly emotional, having lusted after the blue meters since I got into this “hobby” back in the 70’s. In my perusing of the Audio Classics site I stumbled upon a b-stock Marantz PM-11s3, their previous generation reference integrated. Researching the Marantz led me to a new Luxman L-505ux at Music Direct. I know that there’s a myriad of good/great integrateds in this price range, but I’m limited to buying online, preferably from a vendor with a decent return policy. I haven’t listened to any of these amps, rather, I’m going strictly on reputation and the fact that 1 is made in the USA, and the other 2 are made in Japan. This is going to be my last amp, the speakers “may” change, but this is it for the amp department. Any thoughts or impressions on these 3 would be greatly appreciated. I am open to other suggestions (integrated only), but it has to be no more than $5k and from an online vendor with a good return policy (think Crutchfield or Music Direct). Thanks.
