NAP 300 DR with my other components

Honestly, I think you know the answer.

Presumably, the only possible mitigating factor in your choice would be the price difference between the two?

NAP 300 DR is bar far a better power amp. Especially with such a talented pre, it will just shine.

I couldn't agree more with Adam. 300DR is exceptional for timbres, PRaT, cohesion, authority, transparence and staging.

Me too

I'd take a careful look (listen) at the speakers first and make sure they can pass on what you invest in amp-wise. Try either at home first if possible.

The speakers listed in the OP's profile are 4-ohm and 87 dB. If I could afford the 300DR I wouldn't waste my time demoing the 250. Other maker's amps perhaps. A more powerful amp as well.

Having originally used the 250dr then changing to the 300dr in my system the 300dr is on  a different level  altogether well worth the additional cost probably the most cost effective upgrade I have made ?

been there with my system NDX/282/HCDR/200, had demo of 250DR and that was going to be the way forward, my dealer then contacted me with a SH 300 (non DR) they had just taken in PX

no contest - IMO even the non DR 300 has more musical detail, focus than the 250DR this is not in anyway a negative on 250DR, but I liked the sound delivery of the 300

I had the 300 DR earlier this year and the difference in the system, control focus seperation is outstanding

IMO the 300DR is a real star in the AMP range and with your 552!

I have an hesitation because it's seems that the sound in less warm with the 300DR for the sound. The NAP250 DR would be more warm on sonic aspect. Is ti true or false? I don't know really!!!

Where on earth did you get this one from????

If you can buy NAP 300 DR then just audition one and if you disslike it, don’t buy it. If you like It just buy it.  It really is as simple as that.

And most importantly - enjoy the music. The Why! 

The 300 will deliver plenty of current into those when needed, just keep its ps away from the 552 head unit i.e. not on the same level or higher on the adjacent stack of Fraim and try to keep its burndys off the floor nevertheless, the 250 avoids all that cable wrestling of course. The pre dr 250-2 is reckoned to have a fuller sound than the dr version.

for a SF olympica 3 you really want the 300 DR.

The 250DR has lesser  ability to dissipate heat than 300 DR which has a cooling fan... 

Just buy the 300 DR. Sonus Faber are demanding speakers and really need the best partnering kit.

I would say in my experience having owned a 200 for 12 years it is more like the sound signature of the 300 non DR

the new 250DR is closer to the old 300 non DR and the DR on the 250 brings in that warmth 

to be honest the 300DR is on another level all together and should really work with your 552, I could not get on with 252/200 but 250 or 300 should give you far more detail and warmth 

but it's a personal choice but I would not hesitate on 300DR

Thanks a lot. You gave to me an interesting opinion. I thing that's it's correct to say to me that that my 552 DR bring perhaps the wanted warmth. It' sure also tha my NDX 2 with it's Ps 555 DR  in correct and help to obtain warmth in all my audio system.

It's sure that the 250 is not the same price than a 300....But at 68 years old, I want a définitive system complete at the end of 2018: just for the rest of my life!!!...lol  !!!!

I would disagree with that. I just had my 250-2 upgraded to DR this summer and the DR is better in every way, including a fuller/richer presentation.

Last question.

Do you know number of Watts /channel in 4 ohms for the 300DR?

Naim don't give this information in specs.

In 8 ohms, it' really 90w / channel

Naim don't publish that data.  however they do show a copy of HiFi Critic the www magazine who tested it & report.  "This is a powerful amplifier despite its modest claims, and will do 165W/ch into 4ohms, 244 pulsed into 2ohms and 325W pulsed into 1ohm"

Full report including watts at different frequencies .........

i sold recently my nap300dr and get a 250dr ( financial need).   To my surprise, the 250dr is better balanced with my system.  I prefer it.   The 300dr was more impressive, bigger sounding, bigger soundstage, more body.  But my room is not big ( 19m2) and my speakers have easy load( 92db, 8 ohm). 

In my system, the 250dr  is more agile, a bit faster.  The 300dr was sometimes a bit too heavy, too much body.

However,  the OP speakers are more difficult to run than mine.  Normally, in his system, the 300dr should easily outperform the 250dr and will be a good match with the 552.

Yes - they do. The clue is in the name:

2 x 150W @4 ohms = NAP 300

Juno,

I run a 250.2 into Sonus Faber Olympica 1.  They are fantastic speakers, and the 250 drives them rather well, but driven at higher levels it gets quite warm!  I suspect the Olympica 3's would demand a little more and whilst I'm sure the 250DR would do an admirable job, I would take the advice already given and go for the 300DR if funds permit... your system certainly deserves a 300DR!

As a 250DR owner if someone would like to drop a 300 in my system.  And provide the extra shelf...................

Hi!

sonus faber like to have a lot of power and current.   Normally, if you have no problems with bass boom in your room, the nap300dr should be better in your system.   But the best would be to test both at your home.  

For myself i prefer the nap250dr in my system and room.   I compared both at my dealer place with nac 252.  Same speakers.   The room was 30m2.  The nap300dr was more impressive but on some tracks the 250 dr was a bit quicker.  I bought the nap300dr finally, but today i know i didn’t made the best choice, i should have tested at home.
