Raidho D1 audition



Two weeks ago I have heard the Raidho D1 speakers in a hi-end shop in Amsterdam (A10 audio). Surprisingly, but luckily for me, I was the only one attending the "morning" demonstration. I could listen all the CD that I brought with me sitting in the sweet spot and without any disturbances.

The D1 where driven by the Jeff Rowland Corus preamp and the 625 power amp. There were two CD players hooked up, i.e. the dCS Vivaldy and an EMM labs single box retailing at roughly 30k euros (I did not asked which model it was). The dealer told me that the system was optimized for the dCS player, meaning he has used his most expensive cables costing around 30K euros. He did not mention which brand of cables he used and I did not bother asking as I find it silly to use cables that cost as much as the pre-power combo (we all have our prejudice in this regard).

The D1s sounded certainly nice, very detailed and fast but also with a very full midrange. Resolution-wise, one would have a rather hard time to find speakers that are more transparent in the midrange and highs (IMO of course). Speed-wise, while very fast, the D1s are not as fast as horns or electrostatics. The stereo image and soundstage were quite good (given the fact that the listen room was filled with other electronics and speakers) and together with the very detail and full midrange made for a rather impressive presence of the speaker in the room. That is, voices and most instruments where rendered with full body and size with a confidence typically associated to large speakers (at least in my experience).

I could not really judge the bass output of the D1s, as the room was quite large (given the D1s' size), plus the position of the speakers in the room was not chosen to give the best bass response but rather a good stereo image and soundstage. Nonetheless, it seemed decent. However, given the level of performance in the midrange and high departments, it would be a pity to not add one or two top of the line subwoofers (in fact as many as necessary) to achieve a world class performance also in this department.

I have quite a bit of experience with moderately high priced monitors like Dynaudio C1 (mk 1&2), Focal Micro Be & Diablo, Wilson Duette and Vivid Audio V1.5. Among these monitors, the Focal Diablo sounds the closest to the D1s, i.e. fast and detailed. The Vivid V1.5 has also a similar presentation. While the D1s sounded much better than any of these monitors, I find it hard to say how much better it really is. Not only I have listen these speakers in different system and room and at very different times, but one should not underestimate the effect made by the dCS Vivaldi in the D1 demo I had. (The Vivaldi was a marvelous cd player to say the least, though at 90K euros ones should not be surprised.) Maybe I should also mention here that the dealer told me that in his opinion the D1s are above the Magico Q1 (while being cheaper here in Europe). Since I have never listened the Q1s, I can not make any comment in this regard, but the dealer carries Magico speakers for a long time and has first hand experience with the Q1s.

I would conclude by saying that I was quite impress with the Raidho D1 speakers. 17k euros (including stands) is certainly a lot of money for a monitor with limited bass, but the reality is that 17K represents only a fraction of the price of other expensive monitors, e.g. TAD CR1. (I would be really interested to hear from people who have listen the TAD CR1 monitor and also the Raidho D1s).

Finally, I should acknowledging A10 audio in Amsterdam (www.a10audio.nl) for putting together a very nice demo.

Kiwi_1282001, the dealer told me he has set up Q1 speakers (how often or
how many I do not know). I do not know how many hours the D1s have been
played before the show. I believe the pair belonged to the dutch distributor.
Regarding the room, the situation was certainly not bad, the D1 were out into
the room far from any room boundaries and/or speakers and other
equipments.

Sabai, last year in Munich I was extremely impress with the TAD Evolution
speakers and this under show conditions. I was told that the TAD CR1 are
even better. This is why I am curious about them.

Maxgalla and Windmolen, now that you have mentioned it, I remember
reading on the Concerto Audio's site that they are the only official dutch
dealer for Magico speakers. Since A10 audio has Magico speaker in their show
room for some time now, I did not put much though into this. However, I have
never said that A10 audio is the official Magico dealer. I merely reported what
I was told, i.e. that Alex from A10 audio has first hand experience with the
Magico Q1 speakers.

Windmolen, if you have experience with the two speaker why not elaborate a
bit on the topic. I am sure many (including myself) will be interested in such a
comparison.

Sidekick_i, how does one get to be invited to the Raidho factory? :) Please
report back, here or in a separate thread. Happy listening!

Hi guys,

I'm sorry for the very late reply.

First I would like to mentioned that I though a bit about the posts of Maxgalla and Windmolen above, and I find them rather dubious. They seems to have subscribed on Audiogon only to point out that A10 Audio in Amsterdam is not an official Magico dealer. Furthermore, the next day after my last post here I got a mail from the dealer (who put together the D1 demo) with details about his experience with the Magico Q1 speakers. Apparently, he has set up (together with the Magico distributor) the Magico Q1 speaker for an audio show using his own electronics (Zanden and Soulution), and also listen to the Q1s more than once in combination with Soulution electronics.

At first I was a bit surprised by this whole turn of events, but then I've realized that Magico speakers are advertised rather aggressively on most of the hi-fi sites I visit. It seems they train their dealers (at least the dutch ones) to be just as aggressive. :)

Coming back on topic, here are my answers to the posts "addressed" to me:

Sidekick_i, thanks for the report about your tour of the Raidho factory. Did you have the chance to compare the D and C monitors. If yes, can you elaborate a bit on the differences?

Sabai and Dracule1, thanks for sharing your experience with the TAD and Raidho speakers. I agree with Dracule1 that comparing two speakers in two different systems that are also in different rooms is of limited value. Unfortunately, often this is the only thing we can do. Also, based on my limited experience with the Raidho D1 and the TAD Evolution speakers, I agree with Dracule1 that the C1.1 (or the D1s for that matter) can not totally outclass the TAD CR1 speakers. In fact, based on the experience I had last year in Munich with the TAD Evolution speakers (hooked up to top of the line TAD electronics) I find it very hard that any system at any price can totally outclass that TAD system. (As mentioned before, the TAD CR1 model is supposed to be better than the Evolution model.)

Wenrhuang, when I had the C1s in my system I have liked them very very much. The two brands have very different presentations, quite opposite IMO. I would call the Raidho presentation transparent, while the Dynaudio presentation dark. IMO the Raidho C and D monitors are much faster and more detailed than the Dynaudio C1, but the Dyns have a more fuller sound. Which one would one prefer is a matter of taste. I should also say that, compared to my current speakers (Avantgarde UNO G2) both my previous monitors (Dynaudio C1 and Focal Micor utopia Be) sounded slow and "boxy" (almost broken). While I did not compared directly the Raidho D1 monitors with my UNOs, my guess is that they will compare better than the Focal Micro Be and the Dynaudio C1.

Razmika, when one goes to a well organized demonstration into a shop that is stuffed with a lot of expensive electronics (beside the ones demonstrated) and also finds a very friendly and accommodating dealer, one does not ask the dealer whether or not he is an official dealer for all the products that are displayed in the shop (IMO of course). As mentioned before, I have seen Magico speaker in that shop for quite some time now, i.e. 2 years or so.

I do not think I've made any bad comments or untrue, for that matter, about Magico speakers. If anything, I have politely asked the guy who claims that has experience with both speakers (D1 and Q1) to elaborate. I have reopened the discussion about Magico because I have found the situation strange. On the one hand, the two poster mentioned in my previous post subscribed on audiogon only to point out that A10 Audio is not an official Magico dealer, and on the other hand, the dealer who organized the demo was also informed that he is not an official Magico dealer and consequently he wrote me (without being informed by me about my "review") to explain the situation in more details.

I've taken the time to shared me experience here in the hope that other will do the same and we can all have a constructive discussion about the Raidho D1 speakers and maybe also about their direct competition, e.g. Magico Q1, TAD CR1, Raidho C1.1, etc. So, I do not quite understand your tone.

Regarding your visit to USA, you should realize that USA spans almost a third of a continent ...

Michaelkingdom, thanks for sharing your experience with Magico S1 and
Raidho D1 speakers. Though, I fear this thread has run its course for quite
some time now.

Razmika and Kiwi, the reason I usually post on audiogon is because I like to
share my experience with other and I like to get feed-back from other in the
hope that we all learn something useful. Aren't we bombarded/confused
enough by dealers, reviewers and advertisement with all this hi-tech crap? I
honestly, do not understand what are you trying to achieve.

Kiwi, you obviously have experience with the Raidho C1.1 and D1, yet you did
not bother to write here a single line about these speakers even though quite
a few people seem to be interested in this comparison. You could have written
a few short lines, (and, of course, also direct us to your blog) and not expect
us to read your entire blog which is quite extended. On the other hand, when
Razmika "attached" Raidho, you have written a rather extensive
post. If you are happy with your Raidho D2 speakers, why are you so
defensive?

Razmika, the first post about Audio Salon was by Mes on Apriel 8. He only
claimed that that respective store in Miami carries both brands, i.e. he did not
claimed that the store has both the D1 and the Q1 models on the floor. In
fact, except Dracule1, nobody has claimed somthing like that. My guess is
that Dracule1, did not answer your question because it was too brief/naive,
i.e. you should have mentioned at least the state were you are going as USA is
big (but of course I can not be sure about this). Also, IMO all of the
contributors here that said something about Magico vs. Raidho, did it in a
rather benign way making rather clear that they were talking about personal
preference (I too made it very clear in my opening post that it was the dealer's
opinion and that I can not make any further comments as I did not listen the
Q1s.) Consequently, I do not understand your attitude. Finally, from your
comments above I get the feeling that eventually you have listen the Raidho
D1 speakers, and also that you have experience with the Magico Q1s
speakers. Why don't you share with us your experience about these two
speakers?

Hi Kiwi, your answer is fair.

I've read your blog twice, i.e. the discussions about Raidho. Also, if I remeber correctly I have actually advised Lapierre who pm me to contact you about Raidho. I think I am not the only one here who would have preferred to read here a few short bullet points highlighting the main differences. Like you said, your post is wordy. I am certainly not criticizing you as I often write too long posts :). Moreover, your experience with these monitors seemed to be a bit limited as you did not compared the monitors in your room so I can understand your reluctance.

Regarding Razmika, he behaves like a 5 years old, i.e. asking stupid questions and invoking silly arguments because he did not received the answers he wanted immediately...

Regarding your remark about the physics lab, I believe you are hinting to the fact that I am a physicist. Indeed I am. Unfortunately, while our labs/experiments may be well organized the results are often chaotic. Consequently, the situation in the lab is pretty much like the one in the real world, i.e. it takes many months to actually learn something useful.

Regarding the hi-tech and ground breaking science that goes into all these speakers, IMO opinion it is 90% marketing mambo-jambo. Neither Magico nor Raidho has the technology and/or the proper understanding to develop any of these technologies. In fact these techniques are around for quite some time and are rather well understood and mature. Razmika was right when he said that chemical vapor deposition is a common technique, but then so is finite element analysis employed by Magico. IMO opinion neither Magico nor Raidho brings anything that new to the table. On one hand there are many manufactures putting expensive drives in rectangular boxes, and on the other hand ribbon tweeter are expected to outperform dome ones as they are much much lighter. Of course, I am bashing here the ridiculous advertisements, not the way the Magico and/or Raidho speakers sound.

Paul
Razmika, I assume that in your last post you were refereeing to me, and by
mistake you typed "Nep" instead of "Nvp". I certainly
do not want to argue with anybody here. On the contrary, I am trying to have
a civilized dialog. I certainly did not attack anybody here, neither did I say
anything bad about any speaker manufacture.

I would very much like to know how did you arrive at the conclusion that
Raidho speakers are colored and Magico speakers are not? What type of
measurements did you do? Where did you performed these measurements?

Also, since you are so knowledgeable and I am so ignorant and impolite, I
would very much like to know what is the relation between the Young
modulus and:
1) the level of odd and/or even harmonic distortions in a conical membranes
2) the eigen modes of a conical membrane
3) the degeneracy of the eigen modes of a conical membrane
