Her er en rapport fra CES om Lyngdorf skrevet av den amerikanske Lyngdorf importøren.
" All,
>
> The recent Consumer Electronics Show in Las Vegas was a very
> big production for Lyngdorf Audio, especially since so many of the
> products had either their worldwide premiere, or were being shown
in
> the United States for the first time. The new Lyngdorf products
were
> the RoomPerfect system, the new CD-1 player/transport, the
Millennium
> Mk. IV amplifier, the prototype analog-to-digital converter for the
> Mk. IV (fitted with phono stage), a prototype CD-Pre, the crossover
> version MH-1 (beautifully finished in piano gloss black), and the
> piano gloss black W210 woofers. Of course, the TDA2200, SDA2175,
and
> SDAi2175 amplifiers were all there, as well. Even as long as this
> post is, there were so many new things that a full description
would
> take several "white papers". However, just as an overview...
>
> The RoomPerfect system must be considered a substantial
> improvement on the room correction systems previously available.
With
> better knowledge of the inherent room characteristics (not just
what
> the speaker is doing in the room), overcorrections and false
> corrections based on room reflection differences are basically
> eliminated. First, a measurement is taken at the listening
> position. Then, measurement is made at a minimum of three
randomly
> chosen locations in the listening room to determine what the room
> itself has contributed to the sound. I asked Jan Pedersen, the
> developer of RoomPerfect, about the optimum number of
measurements.
> His PowerPoint presentation already had the graphs loaded! Three
> was indeed the minimum to achieve a reasonable power response
picture
> of the room, then the accuracy gradually improved to nine
> measurements, at which point there was very little to be gained in
> further measurements. With the relatively short calculation times
> needed for each measurement (under two minutes each) I suspect all
> users will run the nine measurements. Once the room information
is
> obtained, you can load and save different listening positions or
even
> different speaker positions (!) since the room information
is "global"
> and the single measurement for a new listening or speaker position
is
> "particular". By the way, you can start using RoomPerfect with
> just three room measurements to get your new toy working, then
later
> add extra measurements to get higher accuracy, without having to do
> everything over. The crossover frequency between MH1s and W210s
at
> CES was 400hz, so the previous 325hz limit before large errors
> occurred is now gone.
>
> One important point not previously mentioned: you do not
> use an outboard computer with RoomPerfect. There may be an
computer
> output added so that inquiring minds can see what has been
measured,
> but the normal operation will be with a microphone plugged into the
> TDA2200, and all information directly taken from the TDA2200
display.
>
>
> The 20 band parametric equalization and
the "tilt"equalization
> (called the "voicing" equalization in the TDA2200 software manual),
> currently provided with the TDA2200, provide ample user correction
for
> the differing source quality-- but, since those are accessed
using an
> outboard computer, I am hoping that there will be changes to the
> TDA2200 to allow equalizer use without the external computer. I
> didn't think to ask at CES, but once the Lyngdorf team is back in
> Denmark and gotten some rest, I suspect we can get an answer about
> this.
>
> As Don mentioned in his earlier report, the "global"
> measurement correction (the room measurements away from the
listening
> position) can be selected, if the user wants general improvement
> throughout the listening room. The "focused" correction
maximizes
> the improvement at the listening position, and will be the usual
> correction chosen. Also, for those who sit in different
positions in
> the listening room, for whatever reason, you can now additionally
> store different "focused" listening positions, to use when you are
not
> in the primary listening spot.
>
> All in all, while the RoomPerfect package is not completely
> finished (as Jan put it, the hardware is there, but the software
needs
> to be completed), already one can see that problems previously
seen in
> room correction are gone, and the convenience of setup greatly
> improved. One can get the sonic result obtained at CES simply by
> pushing buttons on the front of the TDA2200, and moving a
microphone
> around the room.
>
> The CD-1 was not the big news at CES, of course, but it was
> shown for the first time in the United States. Since the sound of
> the system as a whole was so good, there is no doubt that the CD-1
was
> working well. I really can't say any more about it until I have
used
> one in my own system, since there was no special attention drawn to
> the CD-1 in Las Vegas. Fortunately, there were CD-1s in Austin
when
> I returned from Las Vegas, so I will be listening to one tomorrow.
>
> Likewise, the CD-Pre wasn't discussed much. The fact that
it
> was shown at CES indicates that it is still planned, but no time
frame
> or price was mentioned. For those not wanting to change
> amplifiers, the CD-Pre is still an interesting option.
>
> The Millennium Mk.IV, playing LP records through the
prototype
> ADC and phono stage, sounded just great. The speakers were MH1s
> without W210 woofers in a small room. Once again, the
demonstration
> showed that the best LP through the best LP player is still better
> overall than the best CD through the best CD player. The turntable
> was a Clearaudio, I think, with an Ortofon cartridge. I didn't
pay
> much attention to the actual models of the phono front end, as you
can
> tell, but the turntable, arm, and cartridge all
looked "appropriate"
> and definitely sounded like a good match with the Millennium
components.
>
> Congratulations to the Lyngdorf Audio team for the sound and
> general presentation at CES last week. I have no doubt 2006
will be
> a very good year.
