In the Thread: A listening room for a domesticated Cat?
Post Subject: Nice but need more workPosted by Romy the Cat on: 10/16/2017
Yesterday I have a great listening time. I sent Amy with twins
to her parents. I put Thomas to sleep in his room and as he woke up I set him
to watch his Caillou for hours and I went to my listening room to have nice quality
time with my playback. I had so much pleasure yesterday that it is hard to
express. I did some fiddling with playback I have 2-3 hours pure marinating in
my listening chair to listen the music I like. I ended up falling asleep in my
chair, blasting Bruckner at full volume. This is in fact a good sign, it means I
am getting more comfortable with the sound in my listening room. It was as much
pleasure as I use to have during my time what I was single. The exception is
that I was able to smoke my beloved Perdomo 20th Anniversary cigars but no smoking
in hour nowadays…
Anyhow, I setup back my computer to play mucks. It took for
me 1.5 years to do but the DAW is back. I found a good configuration for movie.
I use OPPOs analog output to drive SS amp with Dunvavy III what my family want
to watch sports or cartoons. And I use OPPO digital out to drive Lavry 924 and
then to maim Milq-Macondo playback when I want to watch opera or concerts or whatever
video program that need good sound. This is very good configuration as the SS
amps in this setting does not drive interest in any way with my main playback
and I can run SS playback in complete isolation.
The overall sound: I’m getting there. The idea use Milq to
drive my woofer tower is completed with great success. The woofer towers are at
20Hz second order on left and 40Hz on right with complementary midbass above. It
is very nice low octave range. I have some strange addiction to my pimpled Scanspeaks
drivers. I adopted them in 1999-2000 when John Dunvaly converted his SC-IV speakers
to SC-IVA, pretty much replacing woofers he used before with drivers 10” pimpled
Scanspeaks. The SC-IVA were very well accepted for very positive change in
bass. I hear the SC-IVA ion some kind of audio shop in Belgume, it was driver
by some kind of little Czechoslovakia tube amplifier and it had a spectacular
bass. I said: Wow! And fallen in love to it. As I got home I got a woofer tower
from John with 4 drivers and I love each second or it. The drivers use the Scan-Speak
SD-1 motor and it is unique. It was invented by Lars Goller in 1992 and the
idea was to have VC much longer to assure that at any exertion the VC will be
in linear part of the magnetic saturation. The guy who runs North Creek Music
does explains the notion very properly:

I am not sure if the excessive VC is better than overhand VC
as AuraSound use to do but nowadays no one do the proper overhand as it too expensive.
For sure the direction the Scan-Speak went waste a lot of efficiency of the
drivers and this sucks for sure. If the driver were not 88.5dB but 98dB it would
be so much more fun!!!
Anyhow, I am not sure what makes my 10” pimpled Scanspeaks
to sound so appealing to me. The best think
about them is accommodations. Most of the drivers sound predictable. You load
them in the way how you load them and the drivers sound in accordance with their
damping characteristic. For the no-feedback SET it is a typical transient vs harmonics
compromise. There is nothing to invent in there. Not with my pimpled Scanspeaks.
The pimpled Scanspeaks for all intended purposes sound like heavily over-damped
drivers. Still, if the signal calls them to throw some so transient balls then
the driver do it for some reasons. I have no idea why. I absolutely love how the over-damped pimpled Scanspeaks
sound and now as I ride above them the super dry midbass Vitavox it is even
more exiting.
With the lower octave questions is fading away I think the
only problem is left with my playback is imaging. The midbass channels are
still not properly times, the different crossovers have own phase disturbances
and the overall imagine is not as good as I use to. The 6-7 feet integration is
not work well now as at some phase problematic recording I have an ugly “hole”
in the middle with right and left channel do not talk to each other. It take a very accurate time alignment or everything
to make the trick to work. I can’t also to move the R and L channels closer to each
other as I have 125” screen is dropping between. So, I am planning to virtualize
the middle aims by moving the mibdbasas between the channels but looking lower
bass outside. It would require to move the amps somewhere but I am willing to
do it. I think I will be in a good shape with my new listing room eventually.
