Just in case anyone is interested in the Marantz Model 30 with the 1723 Monitors this is my take on the pairing and ONLY my experience. I have an NAD C-370 that’s been around for a good while. One day, I started thinking, maybe I’m missing something because of all the new integrated amplifiers out there. So, taking the plunge, I purchased the Marantz (luckily with a 60 day return policy). The Marantz (a modern class D) as reported by some, has a pronounced midrange and an extended low end. They were correct in my experience. To make this to the point, it was too much of a good thing in the midrange, just way to much. The low end was so extended, I just couln’t get it dialed in with my subwoofer. If I wasn’t using a sub, it probably would have been great, but the midrange still wouldn’t work. I’m not into tone controls and really don’t think it would have solved the issue. So, what I found in my trial, was the NAD was very neutral from top to bottom and the Arendals seem to love this kind of amplifier. This was a very important lesson for me if purchasing another amplifier in the future. I’m sharing this experience as it may be helpful to anyone looking to change amplifiers. I’m not saying the Marantz is a bad amplifier at all, it will certainly be loved by many, in my opinion it’s just not neutral enough for my liking.
