UnPromeneurEcoutant's review (This content has been automatically translated from French)" Serious monitoring"

PSI Audio A21-M
Technology treating the phase response was heckled me on paper and in two minutes of listening I was convinced.

Also I like the attention given to the insulation of the amplifiers in each speaker, spring loaded. These are serious people.


For what concerns the color, it is clearly in Switzerland.
To have listened to many times the A21m alongside the A17 and A25, we are immediately struck by their similarity, the only notable differences being the extent of vertical listening axis and the extent of the bass response.
On this last point the A21m down low enough to spend this sub and work peacefully. Provided you have good feet inert to ensure good reproduction.

From the perspective of microdynamic, work the compressor is very easy, the speakers compressing very little signal, the more subtle changes are audible without force.

The stereo image is gorgeous. Here clearly the only inaccuracies that could be met are to be attributed to the listening room where the quality of care.
If cutting is good that each element of the master can be isolated, we can concentrate without problem on their tone and have a royal retreat on the scene.


I use it for almost 1 year, RAS, it's solid, and to keep away from curious little hands, I have the option with grids if necessary.

One day a friend comes to me and hears with his songs reference. Horror!
According to him, if the speakers made no good (or nothing good must see ...) it was their fault, they were inappropriate to the "real world." None of his songs were "good" and laughing PSI and made him bleed ruthless in both ears.

I listen to other models before acquiring PMC TB2S + very attractive but remains in the range of below, Focal Solo6be more draft, then I do not want to pay their com 'or aesthetic design, Genelec 1031A j not like when it ment, Klinger Favre on which I could not make up my mind as they were not supported by a sound of the most famous, same for Adam SX3 and Focal SM9 listened to a Parisian dealer well known in pitiful conditions.
Aside from Klinger Favre where I'll have to revert, the others are at much lower rates.
In fact I was not party to this range there but an opportunity presented itself and I was able to acquire a pair for cheaper than new pmc.

My best buy in the studio with the Schoeps yet!
Somewhat in excess but it's so good!

g.dps's review (This content has been automatically translated from French)" Perfection is possible?"

PSI Audio A21-M
My choice was motivated by the absence of negative reviews on this product after extensive research on the net in this range of speakers.
They come form the final element and the mistress of a purely amateur small home studio room, after a sound card RME Fireface 800.
The main features are on the home page of the product on AF or PSI Audio website, so I did not dwell. However I take this section to tell a resident not too far, I had the chance to get them in Switzerland directly from the manufacturer, meet the designer Alain Roux and visit the premises. This is a family business, craft, led by passionate, and nothing is left to chance in a production line especially careful where everything is tested at every stage. Hat.


Tone, neutrality, dynamics, precision and stereo are simply fabulous.
I will complete my opinion after further use, but already:
- I just spent a few hours to test all types of music in a local untreated (shame on me, but it will come) and I did not at fault unpleasant listening and / or tiring;
- We used to say that "rediscovered" his songs with new speakers, and this is normal: it is the case with any listening system because it is in the excitement of novelty ( psychologically ear is predisposed to be indulgent), we forget what goes over the former focusing on the sounds that appear in clear we are not objective! A-21M does not let me this impression. Nothing has gone all sounds stand out clearly, a real treat!
- For information (and random) my most significant test was with the song "Alpha" by Vangelis. It offers the triple advantage of being on a slow tempo in order to concentrate on listening, presenting a progressive "stacking" soundtracks the beginning until the final climax, having both crystalline waterfalls happily flirt with 10 kHz or more and percussive sounds and layers that can scan the entire spectrum. A good listen on CD or Wav faithful to the original, if you lose a lot of momentum!

Last but not least, the power reserve is comfortable, and the A-21M go smoothly sub, except perhaps in very large boards but as this is not my case ...


For now I only use them since yesterday ... I have not tried others, where I live I do not have the opportunity. This is a blind purchase, but not quite as I thoroughly searched the net before: tests, reviews, forums ...
So far I like everything, an irreproachable manufacturing quality to a remarkable precision in sound reproduction, but as I said above I will complete in use.
Only negative point but is not really when you consider that these speakers are designed initially for the broadcasting, the volume control is via a trimmer on the rear. So I have to play with virtual faders my sound card but Palmer Monicon (recently tested AF) will come soon make my life easier at this level.

Difficult to talk about price / quality ratio. Even if it is in doubt the most important element of a (home) studio, everyone can not put € 4,000 in a pair of monitor speakers. I had this opportunity and can only rejoice. I would say that quality has a price, and that for the A-21M it is perfectly justified. No notion of snobbery or razzle-l'oeil in PSI is not the kind of home: quality, only quality, simple and unfussy.

If I had the budget I'd probably me turned to A-25M, but objectively they would probably have been oversized in relation to the use I'm going to do.
Finally, and since I made tracks there, it should be noted that all PSI range has the same quality, the A-14 and A-17 are also excellent, only the bass reproduction "suffers" and it makes sense, with a diameter smaller woofer.

I have yet to experience ... But if I had the choice again and behind the budget, yes, without hesitation!

Paranoiak's review (This content has been automatically translated from French)" Killing!"

PSI Audio A21-M
Owner of a pair of Dynaudio Acoustics BM6A (for sale), a pair of ADAM S3X-V, I wanted to buy a new pair of smaller monitors for my future apartment.

After going through a lot of forums, I stumbled by chance on these little wonders.

I mainly consists of electronic music (10 years), mainly Techno, Industrial and Experimental. My influences range from Jeff Mills to Venetian Snares.


I do not think they are completely lapped but after more than ten hours of listening, I am completely satisfied.

An impressive bass response for the size of these monitors.
A stereo image really beautiful (IMHO better than ADAM).
A stunning development of reverbs and dynamics of the mixes.


This is hardly a week that I use. I have tested the models mentioned above ... In New Caledonia, the market monitors quality assets is completely non-existent ... : (

What I like most, the stereo, the neutrality issue, the return of the slightest lack of mixing, although present at low (no sub).

What I like least, realize that some mixes are shit for once and become super demanding what I listen. I will end up being a very audiophile snob! (Humor)

The price / quality ratio is good for the budget! They are expensive but the price is fully justified!

I can only advise you to listen for yourself! Unfortunately I do not have and I have to buy blind ...

My best buy in music (for now)!
