YG Acoustics add in Stereophile

Stereo_phile, your finding are very interesting indeed. It would concern me if the sides of these speakers were vibrating as you have mentioned along with the midrange driver working so hard.

Regarding the vibration, these cabinets are aluminum so that would add a unwanted sonic signature which I would not think is pleasant. Regarding box speakers this has always been one off the negatives, the box interacting. There are box speakers out there that I have experienced that do not have this issue, Egglestons, Artemis and I have heard that the Rockport Altairs to name a few.

Interesting that your friend "slash dealer" has a very large listening room and that you kept making reference to him having many high end speakers along with mentioning he had MBL 111's and that the dynamics did not match up to the Anat Reference II Studio speakers.

Your friend should be using the MBL 101E's and not 111's, the 101E's would be better up for this task especially if it is a large room and secondly choice of amplification would have an effect and your issues regarding dynamics and transients would be non existent. The Anat Reference II Studio speakers do have a powered sub correct so you are only driving the top.

If comparison are to be done they should be done comparing apples to apples and not apples to oranges.

I personally have not heard Anat Reference II Studio speakers but a few who have have told me they are nothing special but others have said the yare worth a listen so I look forward to hearing them but if the cabinets which are aluminum are vibrating would concern me as it would add unwanted sonics.

The Dynaudio Evidence Temptation, I have heard these many times and would have to disagree with your findings but they are your opinions, I also read that you got rid of yours and read why. I believe there were other issues going on and the speakers were not to be the blame. I heard the Temptation's sound best when paired up with McIntosh 2KW amps and 1000P pre-amp in a rather large room where they can breath. 6-8 feet space behind the speakers to the wall, 5-6 feet space from the outside of the speaker to the wall and aprox. 8-9 feet between them and not like they were positioned in your room as per your pics. I would suspect the speakers you chose might be a better fit per size wise which are very nice speakers also but at the same time if the set-up is the same as per your pics it would be far from ideal and in my opinion you are not really getting to hear the full potential of the speakers. The Anat Reference II Studio speakers may work even better due to their design.

Kusina on 11-17-08: your post said I have a Burmester 911 Mk 3 amp. While the Burmester 011 pre is perfect for it, I chose not to use that pre because it lacks a balance control. After trying an MBL 5011, I ended up with a Krell Evo 202, which has a 50 ohm output impedance (the Burmester amp likes a pre with a low output impedance). After some experimentation with interconnects, I purchased a Kimber Select 1136

Your reply above seems to differ from this can you clarify.

Everyone...please don't read specs..listen with your ears - preferably in your own environment. It makes no difference at all if a speaker manufacturer says it's the flattest speaker..even if the boast is true...over what range?...at what sound pressure level...what about resonances??...how integrated are the various drivers themselves?...is it time aligned?...how fast do the drivers respond...do the speakers react to subtle dynamic swings,etc., etc.

i own the rockport altair's and i can tell you without hesitation or any doubt at all that there are no box vibrations. nor do they bottom out. in fact i am still looking for the bottom. i had considered the yg pro but could not get past the look, at $100000 + list price they should be better looking, not just metal pyramids. i also considered the upgraded alexandra 11's and focal grande(although i have not seen these in their new form). i chose the altair for the whole package sound, quality of built, looks(wife factor) warranty(5yr) and price. they are fantastic speaker as they should be.

To clarify, as requested: The earlier post (06/24/08) described my plans at the time to experiment with preamplifiers. The later post (11/17/08) describes what happened after a widened effort at experimentation. I found that the Krell EVO 202, plus a Kimber Select 1136 interconnect, sounded best to me when connected to my Burmester 911 Mk 3 amplifier. That is, that combination sounded better to my ears than my MBL 5010 preamp with a variety of other interconnects (Cardas Golden Reference, Siltech, and several other Kimber Select cables). I believe that the Burmester 911 Mk 3 performs best when coupled to a preamplifier with a low output impedance and an interconnect with relatively low impedance. Among other things, the right combination produces music with more shean or sparkle on top. As to the YG Anat Ref II Studios: mine have never bottomed out, nor have I experiences any cabinet vibraion. I have never played them at extremely high volume levels, but I do play them fairly loud, especially on full orchestra CDs. The front baffles are made of an alloy which is remarkably inert, and the rest of the cabinets are of aircraft grade aluminum. If you want to play music at 100 db or more in very large rooms, the YG Anat Ref II Professionals would probably be a better choice that the Studios, since the Professionals have two powered subwoofers per side whereas thew Studios have only one per side. But I am happy with what I have. With my present electronics and cabling, they come closer to live music than any other system that I have heard.

"rockport altair's and i can tell you without hesitation or any doubt at all that there are no box vibrations."

Of course they do not vibrate. They have a big hole in the back… You did not find the bottom since, being a ported design, you do not have much of it. Having said that, it does sound like the YG do not have a high-pass filter on the mids. Not very smart and quite a bit of money for what is basically a 2 way with a sub.
