All ratings are relative. This one is too. Marantz is lightly cunning. I will show on example of M-CR603 which I own. Both are the same it seems to me. You can see two measurements in the manual:
(1 kHz, total harmonic distortion 0.7 %, 8 Ω) 40 W + 40 W
(1 kHz, total harmonic distortion 0.7 %, 6 Ω) 50 W + 50 W THD 0,7% !!!
Effective maximum output
(1 kHz, total harmonic distortion 10 %, !!! 8 Ω) 50 W + 50 W
(1 kHz, total harmonic distortion 10 %,!!! 6 Ω) 60 W + 60 W THD 10%!!! Its a noticeable distortion level.
or Denon CEOL N7
Rated output 2-channel driving
65 W + 65 W (4 Ω/ohms, 1 kHz, T.H.D. 0.7 %) The same for Marantz 603 at 4 Ohms as its a hardware duplicate for Denon
Dynamic power 80 W + 80 W (4 Ω/ohm)
or TEAC H-CR500DNT the same class CD receiver
40 W/Ch (6 Ohms, 05%, 1Khz)
So I understand that the real power output of Marantz M-CR at 6 Ohms is 50 W, or 65 W at 4 Ohms, or 40 W at 8 Ohm.
Though it is not recommended to use 4 Ohm speakers on the back of its body, I use Dynadio DM2/7 4 Ohm bookshelves. I've got permission from technical support from Marantz-Europe for this, saying "no problems".
Perhaps you are missing the point.
The most important specification for the 603 (and probably the Denon too) is further down the page. It says....
Maximum power consumption 50 watts.
So unless magic is involved there is absolutely no way that the 603 can sustain any of those power ratings for more than a few fractions of a second. But you know what, it doesn't matter, well most of the time anyway.
We have been through this all before but in essence, with a music signal that 603 will only ever be required to produce a handfull of watts of continuous power as beyond that the music will already be into hard clip.
So with suitable easy to drive speakers and used at reasonable setting of the volume and bass controls all of these systems will perform just fine.
We do so many shows in a row,
And these towns all look the same,
We just pass the time in our hotel room
And wander 'round backstage,
Till the lights come up, and we hear that crowd,
And we remember why we came.
Mugam and SiUK,
thanks for sharing. Planning to pair the 610 with Wharfedale floorstanding speaker with following requirement:
Nominal Impedance 8 Ohms Compatible
Minimum Impedance 3.0 Ohms
Recommended Amplifier Power 25-150W
I bought the 610 for S$660 in Singapore. Consider quite a good price.
You are right I think. I've seen Marantz maximum power consumption of 50 w and had this question of power output and power consumption in mind. But I'm not a technician and studied physics only at school many years ago, so I didn't dare to comment on this. You gave the final answer.
Somone posted video of the silver 610.
I still prefer my black one.
Yeah, wow, in agreement their magnus78. Silver plastic body? No thanks. It looks really tacky to me. Suppose it's a personal thing (and cultural apparently). Nope, black definitely the lesser of two weevils.

I'd guess that would indeed be the case if the power consumtion rating is actually accurate. Then add that even a digital amplifier is 'only' 80 odd percent efficient and quoted figures indeed start to look a little shaky.
However, I believe that these days power consumption ratings are not what they used to be and can be massaged to make things look better. Certain Brystons will probably be a case in point as are several AV receivers.
Perhaps someone here knows more about this but I agree, as long as it sounds good it is good. Care perhaps needs to be taken when choosing speakers.
Nad's new D 3020 looks interesting too and is quoted as being pretty much load stable. Not much info around at the moment and only one review I know off though.
Pretty ... and pretty proud of it
For anyone interested, the 'Party Mode' on the 603 has been removed on the 610. I forgot to mention it a few times and it was actually a really good feature. With the 603s it enabled me to play the same piece of music in every room with a unit in it which was really good. Easy multiroom. Real shame that they decided to remove such a good feature. Anyhow, as much as I like the 610s (I'm keeping two of the 610s where they are now, in the bedrooms) the other will either be going up for sale soon or I'll keep it 'for Ron' but I'm now definitely looking elsewhere, and maybe towards a Naim UnitiQute 2 for the main system downstairs.
SiUK have you thought of adding a subwoofer to your 610 for a bit of extra ooomf ? Incidentally can you give me some pointers as to where to buy a slug load of FLACs ?

I ever tried adding a subwoofer and overall sound did improved.
