5.0 out of 5 stars Wonderful amp at this price point

2026-02-01    -Jason F.

I have a pair of Bowers & Wilkins 804 D3 and 606s at home. I’ve been trying to decide on an amp for the 804s, so I’ve been listening to a lot of stuff. I was curious about the Marantz amp to pair with my 1510 slim receiver - and I have to say I’m impressed. The receiver is pretty “thin” sounding once the volume goes up. Despite the relatively modest 140wpc on this amp, it brings back the power in spades.Compared to more expensive Rotel amps, I find the Marantz to be more full, warm, and musical, perhaps at the slight loss of detailed transparency.The amp doesn’t really stand up to the likes of McIntosh, where the 456 or 9000 far richer detail and musicality. With the McIntosh you can feel every vibration of a string, where as with the Marantz you hear beautiful music.So there it is, this is a great little amp that hangs with competitors 2-3x the price, but very rightfully so doesn’t hang with competitors 10x the price.I think on anything less than B&W 800 series level speakers, this Marantz amp would have you very well covered.

I wish I could give this some stars. I really do. I wanted to love it.Marantz tech-support was great, as they have been with other products that I’ve purchased. After having possession for nine days and spoken to two separate Marantz technicians, confirmed. Product received was defective. Bummer.

5.0 out of 5 stars The perfect amp for my system.

I am super happy with this amp. I am using it to power the front two channels in a 5.1.2 system. I have a yamaha rx-a1080, klipsch r-820f's in front. Klipsch r-34c for center, and r-51m's for surround. Also a pair of rp-140sa for the reflecting front elevation speakers. I am also using a Hsu uls-15 mk2 sub, and an ac infinity aircom t10 fan. I only mention all of that so you can see that I am not running top end equipment, nor is it cheapo junk. The 820's want 150w rms, and I figured that with all channels driven I was probably getting less than half of that. The avr is rated 110w 8ohm with 2channels driven. I am super happy with the sound. My listening room/home theater is also my living room. My front channels sound more live than ever. I use spotify premium for my music source mostly. I only got the fan because I have my turntable on top of the amp and it wasn't letting it breathe properly. Now with the fan on "smart mode" (running either level 1 or 0 out of 6) the amp stays right at 80 degrees F. At this point, I know I have plenty of power for my system, I can't hear any hiss or anything like that. Gunshots in movies sound like gunshots, delicate voices sound like the performer is in the room with you. I love it.

Works very well with my Marantz 1506 Receiver

2026-02-09    -Alan D.

This is a very simple product that performs really well. The floorstanding speakers in my setup needed a bit more power than the 40 watt per channel receiver was giving them, and this provided that; really filled in the sound a lot, max volume is far greater than I could ever want to use.I use this with a Marantz NR1506 receiver and it works perfectly with the included sync cable. The power amp shuts on and off with the receiver, which is in turn controlled by my TV (unless I turn it on for audio-only), so I don't need to worry about switching multiple devices on and off, it all 'just works'.

5.0 out of 5 stars Unexpected audiophile quality!!!

I had to replace my beloved Classé CA200 amp, which while admittedly old, still sounded great until my right channel blew out. I have other Marantz gear in the living room so I replaced the Classé amp in our Lanai with a less powerful and far less expensive Marantz. In fact, the Marantz cost less than half of what the repair of the 20 year old amp would cost. Guess what? The power is perfectly fine and the sound stage is noticeably better. The bass is significantly tighter and there is only clean, hiss and hum free sound. In fact, there is better quality sound throughout the entire power band. The sound surprised me because this application has better speakers than where my other Marantz gear is used. I can hear significant improvement in my higher end Avalon Accoustic speakers with the Marantz and they’re a relative bargain. When the time comes, I’ll certainly consider replacing the Classé equipment in our home theater application with Marantz multi-channel gear. Surprisingly great sounding.

The depth of Russ Freeman & the Rippingtons, Black Diamond has never sounded so good. overall clarity and balance has improved 110% since the addition of the power amp.

The amp arrived today, kudos to the fast shipping! Though there are quite a bit of negative reviews I figured the positive reviews couldn’t be that far off, boy was I wrong. There was no depth or width to the soundstage, and it was terribly muddy. I listened to several types of music and couldn’t find even one with a decent presentation. This might work well in a home theater system but it is nowhere near good enough for critical listening. Boxed it up and it’s going back in the morning.

5.0 out of 5 stars Nice 2-CH power amp

2025-12-23    -PlasmaChroma

Good power amp, I matched this thing with a Marantz receiver and the remote power-on cable works great with it. This thing drives my Klipsch RF-7 II's quite nicely, the quality being in the ballpark of a far more expensive amplifier I tried. Having balanced interconnects is also a nice plus, and probably will be used by many users looking at products in the range of this amp. I get a slight bit of hiss with no signal, but given the speakers I'm using are sensitive as hell it's not too surprising.The posts on the back do feel a little bit cheap though and even have some flex inward when pushing on them.
