Marantz MODEL M1 Wireless Streaming Amplifier

It serms that the DAC in the Marantz M1 Is the modest Burr Brown PCM5121, the same one present in the Wiim Mini (source https://audio.com.pl/testy/stereo/wzmacniacze-stereo/3976-marantz-m1)

What about the ‘Switching, digital end-to-end amplifier topology’? Maybe the PCM5121 is for the subwoofer output?

Can you connect the M1 as an amplifier to a pc with an optical connection? And is this optical connection max 24bit/192khz?

Yes, I guess you are right if this Is a full-digital amplifier.

Fairly sure this has the TPA3255 inside, like the WiiM, quite good specs.

Fairly sure it does not!
“The amp is a marriage of Axign's AX5689 digital Class D amplifier controller with the power stage from Texas Instruments' DRV8932 quad half-bridge driver chip.”

Right, I see multiple references to AX5689. It is bridged design, corresponding to the 4 big coils, two for each channel.

However, the driver chip you mention only does 1.5 Ampere. More is needed to drive a 100 watts.

I find it a bit strange that an expensive amplifier from such a powerful brand doesn't have features that allow us to better adjust the sound, like a room correction system and parametric equalizers. JBL released a 5.1 receiver for $599 that has room correction via a mobile app

The Jbl is awful. The Matantz is getting good reviews. I'd be shocked. if it sounds 600 dollar better than the Wiim pro. However, I would love a more powerful wiim. It lacks just a little punch.

In Brazil, I can have a M1 but can’t have a Wiim. They doesn’t sell here or Paraguay.

Just waiting for M1 measurements to pull the trigger.

I finally got a WiiM Amp Pro and a Marantz M1. I must say that I definitely prefer the M1’s sound to the Amp Pro’s sound. That being said, I do have an issue with the M1. When at low volume, I get a swirly hiss emitting from my speakers. The hiss is not audible at higher volumes, but I do find it to be a bit annoying at low volumes. The HEOS app is better than I remembered, but I still think that WiiM has the best app at the moment.

Yes, the HEOS app is second rate. BubbleUPnP is versatile, it is third party which has some advantages, and the developer is very good at keeping it up to date and chasing down any bug. It is almost freee. It is not as pretty on your Android screen as other control apps, and some parts of its functionality do require you walk up a learning curve.

What you're describing actually sounds like a high noise floor in the DAC.

Another source of hiss is the connections. I had a hiss problem with a coaxial cable connection; it went away when I used the optical Toslink alternative to make the connection.

Thanks for the info. I’ll have to look into this more.

I have ruled out all cables as possible sources of the hiss.

How is the Dolby Plus mode on the M1 with two speakers and movie's?

How is the Dolby Plus mode on the M1 with two speakers and movie's?

I very rarely watch movies, so I can’t comment on that. However, I am on my second M1, and I am still having issues with static, hiss, and intermittent pulsing. I have moved everything to different locations in my house and have tried different cables, speakers, and an AC filter. Unfortunately, nothing has helped. The WiiM, on the other hand, is working great. I am about ready to give up on the M1.

I have the Denon Home Amp rather than the Marantz M1 (and no hiss). One thing to note about Dolby Digital Plus is that the LFE channel is not played through the subwoofer. Using any of the numerous videos that test Dolby Atmos/Digital produces silence with the LFE channel.

Thats too bad. I am currently looking for an minimalistic alternative to a normal AVR, since the price of AVR's are still psychotic here in europe, so taking something like the M1 and giving me a "phantom" -like surround, might meet my needs since I am a movie fan.

Ooo I have not heard about this one. How is the Digital Plus in movies? Do you get some kind of "surround effect"? When you say LFE, you mean Left channel and you don't get any Sub effects, correct?
