Q: is It possible to use a center channel speaker for tv audio? Or does the arc/hdmi only allow you play sound through left and right speakers?

A: Hello. The Model 40n is a two channel integrated amplifier, and thefore does not support the use of a center channel. You can expect to not need a center channel as the left and right speaker will be delivering all the content which would otherwise be delivered by a center channel.

Q: It has a USB connector. Can it play digital files stored in a USD drive?

A: Playing back files stored on a PC or NAS is made possible using the free HEOS app. The USB input is intended for the connection of a USB flash drive. If you have further questions, please get in touch with https://support.marantz.com/ Thank you

Q: can you attach seperate power amp to this unit

A: Hello, The Model 40n does not have a pre-out port for a power amplifier feed. That being said, the current delivery of the Model 40n is so impressive, we struggled to find a pair of speakers it could not drive with composure and authority.

Q: It's made in Japan?

A: Made in Japan yes

    So far, so good. Made in Japan!

    First time buying an open box item at this price point. I was anxious about the condition of the unit as expected. I’m just glad it turned out great enough. The box was beat up and the styrofoam has 2 breaks at the top and bottom, assuming it took the hit when this package was dropped. Since the Marantz was well built, I was confident it didn’t affect it. Upon close inspection the unit had no blemishes or any signs of damage. It truly represented the “excellent” condition rating provided by Best Buy. The unit performs and functions perfectly, so far so good. I can’t give it a 5 until several weeks of use. If I can update later I will do so.

    Sweet

    Very nice unit. I have SR8015 for AVR but wanted a 2 channel streaming option. They brag about the phono stage but no amp I’ve heard has a great phono stage. The amp is beautifully designed. I run apple play off my iPhone , Apple TV, turntable, CD deck and KEF R3 Meta’s and my office rocks. Everything I need all works great and Marantz and the KEF’s are a perfect match. The 40n is warm and the KEFS bright oh SVS micro 3000 too. I haven’t done anything to the Marantz as far as set up because that HEOS app sucks. But I don’t care I don’t need it. I would like to see the Marantz menu though and apparently that’s the only way so I have some things to figure out. But out of the box this is a beautiful sounding amp.

    The statement on the box isn’t something they say with levity. Coming from a svs soundbase 300w class d amp with martin logan xtb100’s to this amp the difference was night and day between their dynamics. The marantz has such a better attention of detail. Songs like ciao papa from the new Pinocchio sounded astounding on the previously mention system but the exsquisite highs, attentive low end and carefully crafted midrange brought the track to such levels of beauty I honestly teared up a bit. Hdam 3 architecture is bar none, not to mention with the hifi class ab circuit its hard to find another amp that straddles this level of fidelity and musicality at a remotely similar value proposition. Also i was very impressed with the quality of the remote, good design, not metal but the in hand feel is very reminiscent of an apple tv remote with the weight and sturdiness.
