@mistermonitors the NAD and Rotel units are both value integrated units from around 15-20 years ago. Nothing wrong with that, both brands have a solid reputation. Rotel for value, their claim to fame is they are solidly built, punch above their weight class by always striving to deliver more value per dollar. NAD is a bigger brand that offers products in various price brackets with some value products all the at up to some higher end gear. I wouldn’t buy one of these older units and bridge them into mono’s, you can but you’ll likely lose more than you’ll gain. The NAD C372 should be a nice option for you, it will likely drive most speakers, NAD has been in the space for a long time producing great products, when this originally launched was a unit that did everything well. If you go the NAD or Rotel route, don’t spend too much on them, they retailed between $600-800 when new back 20 years ago. If you can snag one for a $100-200 that’s in good shape, tremendous value if you are going to use it, not much value on the used market.
If you wanted to go with a modern integrated there are some good options in the $1,000-2,000 range but that’s a big jump from what you are looking at. If you went with a more modern integrated you might not really gain much in performance but you would potentially gain a unit set up for a more modern set up incorporating streaming / digital.
