While the review was very positive overall, at this price point, one might anticipate less simple and more attractive exterior design.

Perhaps they will offer updated casework in a MkII version. Of course at a significant price increase.

You can see it like this.

But there will be quite a few people who would never buy large Gryphon or Boulder, Vitus, Pass or similar amps simply because they find the look unpleasant or even brutal. Or because they don't want an amp that they can't actually move on their own.

I think the look and dimensions of the JMF devices are marvellous (although I only have a JMF mains filter myself and otherwise huge, heavy devices from Aries Cerat).

I myself only buy from one point of view: sound quality. I can understand people who also want a discreet look. But I have no sympathy for somehow "blowing up" the visual appearance for a given sound quality. I therefore very much hope that any future visual changes will be made.

Sorry, I think you got me wrong, for attractive box design you don’t have too be monstrous size or in your face like d'agostino amp.
look at accuphase, dcs, ch, boulder, goldmund, ypsilon and others for attracting “box” design. When you spend this amount of money you can and should expect more.

OK, I see. Especially Soulution or the original CH Precision design are good examples of a very valuable yet restrained look. In the case of Boulder, the design of the last series rather than the current one - and some of them fail because of their sheer size (3060 looks terrible).

I'm kind of surprised that so many of these replies are focused on looks. I happen to agree with Verdier in that the JMF Audio equipment looks very nice. I personally don't see much difference between the JMF cosmetics and the cosmetics of some other high-end brands.

JMF Audio are one of the few who's monoblock amps are not just a bridged stereo amp.

Style is very personal and I find JMF quite pleasant and well finished. I find some other brands beautiful but will not buy them because of the sound, some have average look but sound terrific. I listened to JMF 9001, they are very good but they are not exceptional for me. Sometimes US magazine discover a French high-end product and they like the balance, dynamics, neutrality. Audiophiles should listen for themselves and make their own opinion.

In the end, sound is a question of taste.

I can acknowledge, for example, that CH Precision sounds neutral, or let's say: has no obvious colouration. Above all, it is very high-resolution - there is certainly nothing to hold back. Nevertheless, it lacks important high-end attributes for me. I don't get any physical presence and it usually sounds to my ears as if the musicians don't feel like making music. Other people praise CHP.

So far, I've listened to the JMF Phonostage and found them very good - not that I absolutely had to have them, but definitely really good and involving. It just didn't really fit into my chain at the time. And just as I don't like CHP, someone else might not like JMF (or whatever). There can be no general recommendations because everyone listens differently.
 
I think difference in hearing is quite small but it depends on countries way of listening. This is less the case now than 30 years ago. I'm not a big fan of CHP nor JMF for different reasons. If you live in Europe, come and listen to Apurna, you may be surprised.

I know a lot of mono blocks amplifiers that are not bridged stereo amp.

I appreciate style like Boulder, Constellation or some that are quite different than rectangular boxes more or less refined. D'Agostino is impressive in real life (I see it at Munich 2023) but Captain Nemo look is not my taste. Some are not beautiful but are fine because of the high quality of the materials, finishes. This said, very few brands, even expensive use a true stylist to have a real aesthetic vision. All are in house "stylist" or Engineers that do the job. I worked many decades for a car company, style is never done by Engineers. On the contrary, these car companies use very young stylists (from different countries and continents) to invent something new.

I don't have time for something like this if it doesn't take place at my home or in the immediate vicinity.

Irrespective of this, I find these devices visually very bad.

Where do you live?

Your appreciation of APURNA style is your, it's not the comments I get as feedback. Also sonically they are the best I listened to. I do not say that because I sell APURNA, it's because I find them so good that I sell them and stop all other brand I had in the past.

Sorry, this is a JMF thread. You are welcome to open a thread about Apurna and explain the ideas behind it and its implementation.
ok, but where do you live? are you private or professional?

Does anybody had the chance to compare JMF PRS 1.5 and HQS 6002 with CH Precision L1 and A1.5? It seems not to be possible for me to have a personal comparison within the same audio setup. Would be nice to get some recommendations.
 
You should be able to test and compare it at home.

I had both at home, but unfortunately on different loudspeakers from the same manufacturer, although their characteristics were basically similar. So not at the same time.

I didn't like the CH Precision. They sounded controlled and resolved, but did not convey any joy. You always had the impression that you were listening to a recording. I have only heard CHP quite well with Goebel loudspeakers (which I don't have).

In my experience, JMF always comes closer to a live character, i.e. a certain authenticity. I was also able to understand this well this year at the High End Munich in 2 different systems. However, the amps/preamps from AriesCerat are even better in my opinion - not quite as neutral, but very involving.

While I appreciate the opportunity to hear different CH amplification and electronics including 10 series, I found that the overall sound signature didn't quite match my personal preferences.

In contrast, the JMF setup I experienced at the Hifidelux show a week ago was particularly captivating. I spent a considerable amount of time in the room, exceeding 20 minutes, and appreciated the opportunity to request various tracks, which allowed me to gain a comprehensive understanding of its capabilities.
