Re: [DML] Amplifiers.

The necessity of high power amps?   It will help with to get the best optimal 
sound reproduction.   You may never need, but IT WILL BE THERE IF YOU DO.   A 
good way to compare a basic in dash set up without a high power amp will be 
like our standard PVR engine in our DeLorean.   Having an amp is like having a 
turbo installed on the PVR..... It just helps make a difference when you need 
it.    I am sure that if some of you have the extra cash to get a high power 
amp installed, you will find a difference.   The extra power will help play the 
system louder that will help override the engine noise, the road noise, the 
tire noise and etc. 

As we all know, in the DeLorean, the cabin's layout is small and it is 
terrible for sound reproduction.   The original speakers placements are at it are 
worst and it doesn't help in the sound reproduction and I do find all of these 
issues altering the sound frequencies.   There are frequencies are in 
cancellation or reinforcement that is altering the intended reproduced frequencies.   
This is where an understanding of physics takes over, and there is a lot of 
physics involved and I will not get involved in this area.    Anyway, an 
"equalizer" will help correct some of these frequencies and the discrepancies.   
   
At this point I would like to share some of my findings and experiences with 
my DeLorean.   In the last nine years of ownership, I had four different power 
amps in my DeLorean.   At the present for the last two and a half years in my 
DeLorean, I have a solid state (transistor) amplifier, the "Sinfoni 120.4X" 
amp.    This is the one of few amps that is transistor type and will fit in the 
DeLorean without it being notice or obtrusive.... It is too bad that the amp 
is hidden for it is a real beautiful made amp.   A work of art!   See their 
site:   http://www.sinfoni.com/eng/start.html   

This Sinfoni amp has the output of 95/135 (REAL) watts per channel by four 
channels.   It is the highest output on the market in a single chassis.     It 
will play from the softest to the loudest without any distortion from the 
amp....Only distortions is from the speakers being over worked and heated up when 
playing "rock & oldies."   When I listen to classical and jazz, it has details 
with impact and it is clean!   

For what I really want in my DeLorean is the Butler Amp that is a tube 
design.   See:
http://hometheater.about.com/gi/dynamic/offsite.htm?site=http://www.butleraudi
o.com

This is a real high quality sonic amplifier like the Sinfoni or better in 
some of the sonic areas.   It is so good the many of the famous rock 
contemporaries, jazz and classical musicians have them in their vehicles.   The problem is 
that the tubes run hot and convection for cooling is a must and the DeLorean 
has no place to mount it, unless you will are willing to mount it in the cabin 
and exposing it to prying eyes.   

Anyway, both of these amps are not cheap and they are just two of the best 
out of a handful of high quality amps that are available in the world of the 
automotive high-end "audiophile" equipment. 

Please keep in mind; I said sound reproduction and NOT SOUND REINFORCEMENT.   
The difference is that sound reproduction is producing the original sound 
that was being played and recorded with the details, harmonics, timbre, 
placement, depth, warmth and etc., all intact.   Sound reinforcement is just LOUD ear 
shattering and bursting noise with little no appealing qualities as normal 
"music by the instruments or voices."

>From the teachings of several high-end audio engineers and manufactures: "If 
your sound system can reproduce a 'cello,' then your system is correct."
