Nait 50 speakers

I run my Nait 50 into a pair of Diapason Micra 3 Excel speakers with extremely good results and would recommend. I have always hankered for a listen with the Dynaudio Heritage speakers but alas I don’t think they are available any more (limited edition).

I have seen the beautifully crafted Diapasons on YT and I believe you that they compliment the N50 well.

Yes - they sound as good as they look. Would like to compare to Harbeth/Spendor/Dynaudio at some point. They don’t get many recommendations nor are they mentioned much by other listeners.

After three demo sessions at the local hifi shop I’ve listen to the following speakers with NAIT 50.
ATC scm 19
ATC scm 11
Proac Response DB1
PMC prodigy 1
PMC Prodigy 5
Harbeth LS3/5A
Neat Petite classic
Bowers and Wilkins 706.

The Bowers and Wilkins were by far the best match.
They reveal twice as much music as any of the rest.
In fact whilst all the others were very good in their own right, they seemed to filter out some of the music compared to the Bowers and Wilkins.

I believe the NAIT 50 is best paired with easy to drive speakers. The Harbeth and ATCs are nice but not the best match for all kinds of music.
Both PMCs were ok. The transmission line bass does have a good ‘kick’ although generally sounding no better than the rest.
I liked the Neat petites and the Pro Ac Response DB1s but they did not come close to the natural and reavealing sound of the Bowers 706.
This has all put me in a dilemma as I really would like to pair a British made speaker with my NAIT 50.
I need to find a British made set of speakers that sound close to the Bowers otherwise I shall end up having to buy these ‘Made in China’ ones.
Bowers 805 need a slightly more Watts than the NAIT 50 has.
Maybe Mission 770s worth a listen to.

How about the spendor 4/5?

Hi, I find the Rissell K range of speakers seem to match well the characteristics of the N50… I currently prefer the RK speakers over ATC, PMC and Dynaudio speakers for near to mid field listening on my N50… the RKs seems to provide the air and space in recordings that can make them sound more believable and less like ‘music’.
I have found the N50 quite flexible with speakers, with its peak current of 15 Amps (225 Watts) being able to handle tricky speaker loads well, albeit not at loud party loudness for average sensitivity speakers. The N50 will get rather warm though if it’s working hard.

In addition to the last post of @Simon-in-Suffolk I can add a story about Russell K. loudspeakers, that are used also by other forum members with Naim systems. In Switzerland there is only one dealer (Audiopur in Fribourg) who sells Russel K. I had seen on the homepage that Russell Kauffman himself is coming to workshops and to present the new Red50se, which had been presented at the Bristol Hifi Show 2024. Because I was in the area on business, I stopped by. Russell gave a detailed presentation of his approach to speaker design and demonstrated it with examples (no internal damping, but separate internal chambers for the drivers, connected by holes). The goal is optimal timing and naturalness of voices and instruments, based on months of listening tests, rather than on the basis of measurement protocols.
We first listened to the standard RK red50, then the more elaborate SE version. Since Audiopur is not a Naim dealer, we listened with Rose RS130 and Resolution Cantata with Reson cabling. Even the red50 is an impressive loudspeaker with a wide spectrum, good bass quality and excellent quality in the midrange, upper midrange and high frequencies. It is certainly not a loudspeaker for everyone. It is unadorned and honest, with great strengths in vocals and small ensembles with natural instruments. The SE version (which is, however, also significantly more expensive) is even better in every respect. The bass is deeper, tighter and the clarity and resolution are clearly superior. The tonal balance was absolutely coherent, but also absolutely honest in terms of the quality of the recordings. The Red’s are fast, dynamic and reveal details, especially in the mid and high frequencies they are present. The spatiality in the depth is also impressive, even though I have heard the location of the instruments in the width sharper (maybe even exaggeratedly sharp) with other speakers. It was also surprising that the small Red’s were not overwhelmed in a rather large and deep listening room, especially in the low frequencies. By comparison, we also listened to the Red120SE floor-standing speakers. In the bass and low bass range, they were clearly superior (no wonder given the size of the room). The sound was significantly larger, more voluminous and initially more impressive. However, the Red50SE seemed to me to be almost better in tonality and precision, even though the stage was smaller. Also, given the extra cost of the 120SE, the Red50SE seems to me to be a good choice for listeners with high demands in terms of neutrality and speed. We listened to a variety of music styles and audio samples (including classics like Take Five and Smooth Operator) and many were impressive. I was also amazed that on a Friday afternoon there were always (changing) 5-10 people there, and that they were of all ages, including families, not just grey-haired hi-fi fans. All in all, it was an exciting afternoon and I learned a lot, including about loudspeaker technology. Thanks to Russell for coming and to Michael from Audiopur for the organisation.

Got a lot of time for him, nice guy, and meticulous on set ups.

The third picture has some very weird stuff going on. Is it some sort of caricature effect? It’s most disconcerting.

Wide angle lens & proximity?

No dont care. It is just a snapshot out of the dynamics of the presentation….

I have now reduced the size of the image with the section. It should show the inner structure of the speaker that I mentioned in the post. The photo is not that sharp, but it is only for documentation purposes. I hope that fits.

Anyone paired REVIVAL SPEAKERS with Nait 50 amp?

How are you getting on?
I agree the Nait50 is so beautifully articulated in its bass resolution… it’s completely infectious, the Red50s seem to work well in my room on SolidSteel stands… and bizarre sub bass … where you feel the vibration in the floor…

The RK120s were good, but didn’t gel for my tastes…

I am sure the RK50SEs are outstanding, but given how good the standard 50s are on the SolidSteel stands, I feel it will be very much diminishing returns…

I didn’t knew there was a Red50SE now, foolish me sold my original Red50 (room issues) Wonder what Russel improved to SE ?

Apparently a bit better of everything, but for quite a bit extra outlay.
Intrigued what room issues you had with the 50s

How to get on…Good question. I became aware of the Russel K red 50 (se) through your posts in the forum and your experience with the Nait 50/Cord Dave. I was not familiar with this brand before, which is not very widespread in Switzerland.
At the moment, the Red50se have not yet been officially launched and the price in Switzerland has not yet been set. I hope they won’t be overpriced.
I think a home demo would be a good option when they are available. One advantage would be that I could probably keep my Solidsteel SS6 (with Isoacoustics Gaia III). I also like the look of them very much and I only bought them 2 years ago. But I’m not sure if they’re not too low for the small Red50 or if SS7 stands with 70 cam height are needed to bring them to ear height. In the end, a home demo would also have to show how they work in my room (17 square meters), also with the electronics (Nait50, NDac/XPS, Tellurium Ultra Black II Speaker Cables). But they remain one of my big favorites (next to the Franco Serblin Accords, which are much more expensive)
And yes, in the end, normal red50s are also an alternative, which are also quite inexpensive in comparison. In a direct comparison at the dealer, however, the Red50s were clearly superior.

Too large room

agh yes - the Red50s in my opinion are more for mid to near field listening for that 3D imaging that allows some recordings to envelope around you. I listen about 3 to 4 metres from mine.
If you prefer mid to far field then the RK150s would I suggest be the speaker of consideration.

The new Linn 119 speakers work well with Nait 50 too. They are musically enjoyment.
