Subject: Importance of surface for my amplifier setup?
Hello,
I'm wondering what your opinion is on the importance of the surface an amplifier is put on? Does it matter at all, and if so, would it be possible to explain why?
Thanks in advance!
Regards,
Patrik

Dear Patrik,
Thank you for your e-mail.
It makes no difference what surface you put your Krell amplifier on.
Enjoy!

Hello,
Thank you for your e-mail.
Material of the surface is not important. All that is important is if the surface is strong, level, and sturdy. The surface needs to be strong because most Mark Levinson pieces are heavy. It needs to be level because you don't want the unit falling off the surface, causing damage inside and outside. It needs to be sturdy because again the unit is heavy and you don't want the unit to fall or break the furniture you are placing it on. That is why you want your surface strong, sturdy, and level.

Dear Mats,
Thank you for your recent inquiry about vibration damping in connection with Bryston audio products. The concept of supporting audio electronics in a vibration-damped environment probably arose in the tube era. It's a well known phenomenon of tubes that they are characteristically 'microphonic'. That is, they alter their output in response to external vibration or impact. Thus, tube-type audio electronics can produce audible sounds when tapped or vibrated.
Fortunately, solid-state electronics are not sensitive to vibration and do not produce audible changes or sonic responses from impact or vibration. For that reason, Bryston do not specify vibration-damping mountings for our equipment. We do seal threaded fasteners to prevent loosening in transport or handling, but that has to do with structural integrity and long term reliability.
In short, you may enjoy your Bryston audio equipment,secure in the knowledge that the vibrations from the speakers will not be marred by annoying responses within the electronics.
I hope the above information is satisfactory, but please let me know if you have further questions. Thanks for your support for Bryston audio components!
Sincerely,
Christopher W. Russell
CEO, Bryston Ltd.

Dear Mr.:
The surface that an amplifier sits on isn't really that important, but the
resonant capability of the surface is. In other words, the material the
surface is made of does not matter, however how easily that material
vibrates or resonates does.
Sound tends to make things vibrate. If the system is playing loudly and
your speakers are vibrating, and they are spiked to the floor, and the floor
is vibrating, it can transfer this energy to an amplifier. Microphonics can
then be transferred to the amplifier if it not designed properly and it can
affect the audio signal, producing distortion.

Dear Mr.:
Tube amps are much more sensitive to vibration than solid state, however all
electronics are sensitive to vibration to some extent, even cables. Any
part that an audio signal travels through is susceptible to vibration. This
is why we do not use thin metal heatsinks, but rather machine them - they do
not ring.
With no music playing, turn your preamp up as far as it will go. You should
hear some hiss. Then take the handle end of a screwdriver and bang on the
interconnect cable to the preamp for whatever input is selected. You should
hear noise from the loudspeaker on that channel. This is an extreme example
of the effect vibration can have on a cable.

Dear Patrik
Thank you for your email as follows.
I can confirm that you do not require a special surface to situate your
components, however, please ensure that the products are level
(especially turntables) and there is sufficient ventilation (approx 6
inch gap between products) to prevent overheating.

Dear Sir
thank you for your interest in our products.
Yes, any good audio component will sound better
on a thick plywood board. It is that simple, it
is easy to check and can be cheap to build
(except when made with 2 inches Finland birch
plywood boards).
Casual or poor sounding units will need to
make-up their poor sound with high tech or metal
or mineral stands and devices.
The explaination is given on the web and we can't go much further on this.
let us know more about your present Hifi and experiments...
Please feel free to contact us again for any
question, we remain at your service.

) rätt här, så menar han att en kabel (till exempel) i ett högupplöst highEnd anläggning kan göra större skillnad än i ett midfianläggning. I midfi är det nog inte så stor skillnad och då duger det med en Ekk kabel, vilket det nog inte gör i en äkta HighEnd anläggning, där krävs det nog bättre komponenter.
Fast det skall man ju vara glad över!
