Sony SS-NA5ES Speakers
Sony SS-NA5ES Speakers
Introduction
My first encounter with the SS-NA5ES was during Sony's "Feel the Air" event last year in October. I was quite impressed by the performance of the NA5ES, despite it being paired with a home theater receiver, and setup in a large acoustic space.
This is certainly not your run-of-the-mill speaker. The cabinet is constructed out of Scandinavian birch wood (chosen for it's density due to the slow growth of trees there) and finished in deep brown gloss veneer by craftsmen in Japan. Under dim lighting, it appears to be almost black, and has one of the most impressive lacquer finishes I've seen on a speaker cabinet. Needless to say, the quality of the cabinetry work is top notch.
The rather petite cabinet (355 mm(H) x 205mm (W) x 325mm (D)) is deceptively heavy (10 kg). The woofer is a 130 mm cone driver, while the tweeter is highly unusual. The tweeter is termed by Sony as "I-Array" and has a single 25 mm fabric dome tweeter, flanked by two smaller 19 mm drivers on top and below of the main tweeter unit.
A single pair of binding posts sits below the twin reflex ports which are slightly flared, presumably to reduce port noise. Unusually, the base of the speaker is attached to a metal plate.

The NA5ES retails for a recommended consumer price of S$ 2,499 per piece (yes, they are sold singly), or S$ 4,998 per pair.
Setup
I took much longer than usual to setup these speakers. They did not like my high mass Partington Dreadnought Broadside speaker stands, sounding too damped and restrained. A pair of half-filled Atacama SE24 stands proved to be a far better match.
Coming to amplification, the match with my Gryphon Diablo was personally underwhelming. It sounded alright, but not really up to the mark of my previous experiences with the NA5ES. A pair of Bel Canto Ref 500M monoblock amplifiers sounded much better, but they really performed with my Conrad Johnson GAT and ART mono blocks.
I set up the NA5ES in both my bedroom system and main listening room. In both cases, they were used quite far away from the walls, with a minimum of 90 cm from the rear of the cabinet to back wall, and at least 60 cm from side walls. I ended up toeing in these speakers more than my usual angle of about 10-15 degrees inwards towards the listener, and settled for an angle of just under 30 degrees (being barely able to see the inside edges of the speaker cabinet). Listeners should avoid being too far off the vertical height of the tweeter array. While the I-Array tolerates vertical offset much better than say a ribbon tweeter, it does sound fairly different if your listening position is more than 2-3 inches above the tweeter's height.
Sound
The NA5ES has a very put together and refined sound. It sounds far bigger than it looks, thanks to a dynamic low-end punch and a fondness for higher than average volumes.
Low frequencies are reproduced with a full mid-bass and very nice bloom. Faster music is handled well and the Sony's 130mm woofer (slightly over 5 inches) is capable of moving a good amount of air with commendable agility.
Midrange is smooth and somewhat laidback. There is decent clarity and vocals are presented with a slightly warm and pleasing tone. Some detail is traded-off here, and this is likely to appeal to listeners who want to hear a more musical presentation, rather than those who are seeking a more analytic approach.
Despite having three drivers devoted to high frequencies, the NA5ES sounds anything but bright. The I-Array unit is deployed subtly, with a silkiness and refinement that is quite outstanding. While the treble is very detailed, it is presented with less prominence compared to the rest of the frequencies.
Tonally, these speakers reproduce the piano with more grandeur than usual, but with a slight reduction in attack and articulation. Similarly, string instruments have a sweeter and fuller sound, with less bite. I would hesitate to describe the NA5ES as coloured though. Perhaps a more apt description would be to describe these speakers as romantic and sensuous.
The NA5ES really shines in the areas of coherence, staging and imaging. It presents a very wide and deep soundstage, with very good placement of instruments and the vocalist. The Bel Canto amplifiers tended to portray a flatter perspective and drier top-end, but the Conrad Johnson amplification really added a three-dimensionality and air that I've seldom heard in this price range. The sheer holography of these speakers when paired at such, created such a powerful illusion that I totally forgot my task at hand being momentarily transported to the venue of the recording !
While I greatly appreciated the NA5ES's strengths, it is not perfect (no component ever is). From a pricing point of view, the NA5ES is expensive and has to face-off with very keen competition. Some of it's competitors can outperform the Sony in certain areas for less, but few can compete with it's beauty of tone or ability to soundstage and image so convincingly.
I also found it to be quite fussy with placement, and partnering equipment, necessitating careful matching and setup. A healthy dose of experimentation would likely be required to bring out the best from these speakers.
Conclusion
I must confess to have been very taken with these speakers - they are visually beautiful (sans their underwhelming grills), and really draw you in to the music. They do not resolve to the nth degree, but are always refined, elegant and musically communicative.
I was quite sad when the time came to return these speakers to Sony, and they certainly will be missed.
If you think these speakers may be just the ticket for you, do given them an audition at Sony's flagship store at 313 Somerset.
I would like to thank Sony Singapore, and it's media partner, Waggener Edstrom for supplying the review sample, and making all the necessary arrangements.
