Supernait 2, why 80 watts and not 90?

I won't dispute what you hear, but the reality is the SN2 and the 250-2 DR, as far as I know, both use the same torrid transformer and both have, I believe, the same amount of reserve capacitance. They both swing the same amount of 400VA. Both amps power measured out almost exactly the same in tests conducted by professional reviewers into loads of 8, 4 and 2ohms. As a matter of fact, the SN2 actually put out a few more watts into 8ohm loads. So if there is better control of certain speakers, like No Quarter is expressing, then what I am suggesting is that other things may have come into play. But as far as one being able to drive difficult speakers better than the other, I personally have not experienced it, and I had owned a 250-2 based system for years prior to my current system.

My experience is that the SN2 has never struggled with any speaker that was connected to it that I tried, and neither did the 250.2 I had. I also have used both amps with several Dynaudio speakers I have owned.

In that review from the Hi-Fi Critic, Martin Colloms is quoted as saying. "Frankly it sounded rather more powerful and of higher quality than many substantially more expensive amplifiers, and happily drove my Wilson Sophia 3s as if made for the job."

So, I guess I will have to just say we'll never see eye to eye in this matter, but I still stand by my personal observations, and that is, if the SN2 will struggle with certain speakers, then it's entirely probable that the 250.2DR will also.

The SN2 and 250DR do not have the same torroid transformer. The transistors inside a 250 DR are the 009 from statement amplifier, whereas the SN2 doesn't even have the 007 from the 250.2, more like the transistors from the NAP 200.

Appreciate your enthusiasm for the SN2, but facts are facts.

It was very simple for me. Attached a 250DR to the Superuniti, which sounded great until we heard it with 250DR.

By comparison the 80 W bare SU sounded confused and messy next to the SU/250DR, there was no doubt in my mind the the 250DR was worth the asking price.

the 250DR also has DR regulation which clearly the unregulated amps don't - the noise floor is a lot lower.

The SN2 has DR regulation in its preamp section.

yes but not in the power amp section.

I think it would save a lot of hassle if Naim replaced their 70, 80 and 90W ratings with something like  Enough, Plenty, and Absolutely Loads. Numbers are so boring.

Rumor has it that ‘enough’ was just what JV replied when he was asked for the power rating of the Nait,

Yes, but only the SN2, and the 552 pre-amps have the DR circuit!!!

All of the current Classic preamps are DR powered.

...just so long as you power them from a DR'd power supply.

Sorry, but if they are current, they are powered by either a 200DR, HicapDR, or SupercapDR. I’m not quite sure what the point of this discussion is, but unless you buy non-current components, all of them are DR powered. 

For some reason the article that the OP posted was removed, I'm putting it back so members that may have missed it can read this really in depth review from the Hi-Fi Critic,  I'm also posting the What Hi-Fi review, it's excellent too.

any amplifier even Statement cannot play music

it amplifies a source

so I find your posts meaningless and pretty useless since you never disclosed your source.

Egh duracell

Supernait 2 is a great piece of kit.  I so dearly wanted to love it, when I had it on dem.

Turned up very loud it played better than my Karan does.  Anything past 11 o'clock just turns to saturated compression in my room, so perhaps the SN2 was voiced to sound good in a saturated compressed situation in a small room.

You compared a twice the price amp, and more than double the rated output, 180watts to 80watts?

That makes great sense.

What speakers were you using? I power Sonus faber Venere 2.0s with my SN2. I easily have all the volume I need at 10 o'clock in my medium sized room. The SN2 still has juice and sounds good if I go a little past 10. 

I never tried raising the volume louder. Past 10 is just too loud for my taste and room. Usually at about 9 o'clock on the volume dial I am happy. 

What TOBYJUG describes applies to every Naim amp ever manufactured save possibly the Statement!!!

I guess that's why he doesn't own one.

I think you might have taken the wrong side to what I thought the point I was making here, sorry for the confusion.

The point I thought I was making was that yes, differences of cost and watts isn't always the final outcome of what works in your room, and that in some ways the SN2 amp that cost half as much and less than half the watts outperformed my Karan when played at very high volume. On paper that doesn't make sense, but on experience that was how it worked out in my room.

Sorry TOBYJUG, I was taking your response as sarcasm.
