we rip our cd's to mp3 not wav or other file,why,smaller file size and quality as good as cd, wav, and other HD files.



it comes with windows (free)


Say cd file 30MB mp3 file 3MB 5 minute duration
60 x 5 = 300 sec
30MB x 8 = 240Mb
240Mb / 300 sec = 800Kb per sec audio
now mp3
3MB x 8 = 24Mb
24Mb / 300 sec = 80Kb per sec audio
800kb / 80kb = 10
the cd file is 10 times the mp3 file
do i hear a difference in sound quality?hell no not me!
some may do i dont know?
to me cd = mp3 unreal!!!


Almost same streams but digital radio goes through further modulation and transmission for that reason i consider it inferior to Mp3


I've tried downloading mp3s from sites with lot's of problems
I've downloaded exec youtube converters/downlowders with lot's of problems
then bingo!
after months of failure
i found a site that does the conversion on their servers and you simply downlowd the mp3
works great!


this is a better converter
oh people i'm in heaven!
anything you could wish for is free as mp3


***source: computer and digital files(MP3s)
There is no need to use a DAC your computer has DAC

***amplifier (MoNo)
there is no need to use high POWER

must be GOOD

That's it


1) Low Noise (all,source,amplifier,speaker)

2) Low Distortion (all,source,amplifier,speaker)

3) Extended Frequency (all,source,amplifier,speaker)

4) Tonal Balance (all,source,amplifier,speaker)


The speakers of our systems need to break in for at least 100 hours of playing music,then you'll notice a more natural sound,this is because the drivers of the speakers are new and require adjacement,the amplifiers however don't require any break in and are always ready for great sound.


CD dynamic range 16 bit/ 44.1 khz is capable of 96dB of it maxed to realise that in audio equipment would require roughly a power level 500 watts rms !!!,now who listens at 500 watts?,the highend guys make high power equipment,but they fail,because the listener doesnt listen at that level in an average home room,would go deaf, so,24 bit goes to 144dB even worse!!!. Most recordings on cd's have the same dynamic range of the analog masters minus analog noise, the noise has been taken out through digital signal processing,what this does is they sound better without the noise but the dynamic range is around 60dB not near 96dB.To sum up High-DR and High power suck.


The recording is the most important when it comes to good sound,even with the best equipment if the recording is rubbish the equipment will sound rubbish,Mp3 recordings made at home and posted on the internet are notorious of this,this is not to say mp3's are not good just they need people with skills to be made good recordings.


Not all players play the same,for example when i play mp3's on youtube player direct from online,it lacks impact,when i convert youtube music and play it on exe programs there again differences on impact,although i haven't tested many player programs,i'm very satisfy with windows media player, suprise suprise indeed.


High Resolution Audio is audio beyond cd-audio,the graph above shows the most common HR/HD standards,there's also DSD a non pcm standard, as you can see pcm is a winner, why go with that stupid DSD, Anyway the graph compares all.

PCM digital AUDIO

PCM uncompressed

PCM lossless compressed

PCM lossy compressed


Mp3 1/10th of cd file, this means 90% data loss and compression, and still sounds amazing !, our opinion!.

PCM digital HR / HD Files

PCM compatible File formats capable of storing high-resolution audio include FLAC, ALAC, WAV, AIFF

FLAC (Free Lossless Audio Codec)
ALAC (Apple Lossless Audio Codec)
WAV (Windows Wave Audio)
AIFF (Audio Interchange File Format)

LET'S COMPARE PCM digital HR / HD, CD, and MP3 Files size (3 min duration)

WAV 16/44.1 ~ 30MB
WAV 24/96 ~ 100MB
WAV 24/192 ~ 200MB
MP3 ~ 5MB

WAV 24/192 / MP3 = 40, mp3 is 40 times smaller than the wav-24/192 file
or 2.5% of the wav-24/192 file!

LET'S listen PCM digital HR / HD, CD (3 min duration)

iTUNES plays HR alac,wav,aiff but not flac
anyway the files i played were wav
i could hear no difference in 16/44, 24/96, 24/192
this confirms mp3 is super-good if made good recording

Amplifier POWER (Watts) and LOUDNESS (dBs)

To double the loudness you have to quadruple the amp power (watts).
or double the voltage and current of the amplifier.
so if you double the power of an amp the loudness will increase by 1.33
if you triple the power of an amp the loudness will increase by 1.66 etc. etc.

*please note dB is logarithmic unit

Compressed Lossy Pcm Formats

Which is good?

MP3 (Moving Picture Experts Group Layer-3 Audio)
AAC (Advanced Audio Codec -Apple-)
WMA (Windows Media Audio -microsoft-)

1st - MP3 amazing!
2nd - AAC
3rd - WMA

HR/HD AUDIO Pcm Formats

Which is good?

FLAC (Free Lossless Audio Codec)
ALAC (Apple Lossless Audio Codec)
WAV (Windows Wave Audio)
AIFF (Audio Interchange File Format)

1st - ALAC
2nd - WAV
3rd - AIFF
4th - FLAC

The Recording in Depth

Have already said how important the recording is
but there is the question
is hardware or recording which exceeding which?
let's face it you're not gonna get both at a perfect level
and this means hifi goes out the window
whatever good recording with your good hardware you have you should treasure it
because there is alot of bad recording out there
the reason?,make more money with recordings than with hardware
why?,lower production cost

My View on DACs

Basicly on the market are cheap and expensive DACs but not middle priced
If you decide to go with CD-audio and mp3 your computer_DAC is more than adequate
Many cheap DACs arent good enough,and expensive ones deliver whatever
the format cd audio quality,see my opinion on listening HR/HD on this page
no difference at all between cd-audio and hr/hd-audio
So avoid DACs they create problems not solve them

My View on HD/HR theory

It's all theory
Practically doesn't make sense
Even an analog 200 watt system exceeds human hearing
Bigger amps have higher noise floor than smaller amps
because of higher magnitude of transistor noise (noise floor)
so for high dynamic range the amp can only go up (more watts etc)
what this means it hurts our ears and the health of our hearing
please see dynamic range on this page

The notion of higher frequency range as better audio is theory as well
Practically we cant hear beyond 16khz
higher sample rates are elements beyond human hearing (ultrasonics)
so even when the waveform looks smoother we can't hear it as better
In vision yes HR/HD is real
In sound No


iTUNES for me is better than windows media player
Nothing to do with sound
It comes down to computing power and flexibility
Like google-chrome is better than internet-explorer

Distortion in Audio

Bad designed audio is main source of distortion
distortion may arise in every component
computer,dac,preamp,pwr-amp,even speaker
there are many types of distortion
but here i'll focus on two types
linear and nonlinear
"nonlinear" distortions are the most severe
because it involves clipping
* crossover, clips at device on and off
* power rails, clips at power rails
* spot distortion, clips everywhere (bad electronics)
"linear" distortion is less severe
it slightly changes the tone of sound
* tubes are one example of linear distortion
the sound appears warm or cold etc
* but it can occur in solid state too
to me all distortion is bad
because it corrupts the original sound

Distortion in Audio part II

Amplitude, Phase, Harmonic,Intermodulation,Crosstalk
Amplitude distortion like crossover and clipping are effecting the sound in most severe form
Phase distortion effects the accuracy of sound
Harmonic distortion sprays harmonic frequencies on the sound
One needs to investigate where is the cause of these distortions
The causes can be from electronics and nonelectronics
Phase,Intermodulation,Crosstalk apply to stereo only. Mono is immune of these.

Robustness of analog / digital source media

Let's start with vinyl,to many audiophiles the ultimate of analog
to it there is wear in the form of distortion (linear) with playing
Pops and ticks although can be even with new vinyl
are part of the vinyl experience

Next tape/cassettes this is the most fragile media of both analog and digital
with playing there is loss of quality,although there is sound,the quality
deteriorates with every play in terms of quality,frequency,noise (dynamic range)
drop outs and complete mess

Digital the most robust media ever known
cd's suffer from scratches but they are more reliable than any analog media
digital files (computer audio) are as robust as the sun
they never deteriorate with play time
and last almost for ever
when they die they die with the hardware!!!

Dr Mark Waldrep on HR-audio

I like this Guy he's a good bloke,he and i agree on alot of things
BUT i also disagree with him because he persists on 96/24 PCM HR being better than CD
This Guy knows that computers and memories will become faster and bigger
so hr/hd file size will become a non issue and HD-audio will move forward
and eclipse MP3s and CDs
This is where we are heading because big fish eats the smaller fish
Certainly dont blame him for that
Please read through this page to get into the facts
Anyway enjoy his video

Dr Mark Waldrep's MP3 samplers at

Now Mp3 Recordings as these are rare
Mark's skills irrespective of the format are very good
Like as I said a good recording stands out
and Mark is a skillful Guy
Check his mp3 samplers out at
Pity not pop/rock weren't available

Listening Fatigue in Audio and max loudness exposure

First,Listening Fatigue
Analog is immune of this be it mono or stereo
The real offender is digital because the dynamics are immense
Especially digital stereo
To get around it play music at low levels
MP3 is the least offender
If you still get it,switch to analog.

Now, loudness and exposure
limits of hearing loss

Loudspeaker Bass Impact

To get a good bass impact of a speaker from one to another
Divide min bass frequency of speaker response by the factor of 2
200hz / 2 = 100hz
100hz / 2 = 50hz
50hz / 2 = 25hz

Recordings & mp3s UPDATE

Ladies and Gentelmen read this
Most Recordings of mp3s are rubbish
why,because it's an advertising sampler media
The recordings people wont give you a good recording 99% of the time
why,because it's their source of big money
Mp3 recordings can be as good as it gets
the format is not bad at all !!!,i've got some good recordings to prove it
Now i am a sceptic, do i turn to cd ripping for better quality
even a larger segment of recordings of cds are crap
they dont do justice to cd format !!!
So, i'm thinking where can i buy a good recording
since the recording industry is corrupt or unqualified recording engineers
Trust me when i say mp3s are good i mean it !!!
It's the recordings on mp3 that these morons put to sell again and again in other format
What do i do
Turn to analog,same thing,it's the same bad recording engineers
Any way if you feel your hardware is good and dont like the sound
suspect the recording,simple logic prevails.

MQA digital audio

Google says:
""Master Quality Authenticated (MQA) is an audio codec using lossy compression and a form of file fingerprinting, intended for high fidelity digital audio internet streaming and file download.""

Completely new to me, Never listened to it, let's see what becomes of it, no opinion to offer.

MQA vs MP3

mp3 filesize: 3MB mqa filesize: 30MB
mp3: Free mqa: pay
mp3 sound: ? mqa sound: ?

I compared a few features of each format
and it's clear mp3 is ahead
It will all come down to sound quality (the winner)
Don't hold my breath though
because HR/HD pcm is not better than cd-audio pcm

My final thoughts on mqa
Briefly,mqa applies lossy compression from hr/hd files say 96/24
while mp3 applies lossy compression from cd-audio
now,let's look at the lossy compressions rates roughly
96/24 is about ~100MB and the mqa file is ~30MB thats a lossy compression factor of 3,3 something
now,mp3,cd-audio is about ~30MB and the mp3 file is ~3MB thats a lossy compression factor of 10 something
Clearly the mqa and mp3 live in different galaxies
they behave differently on lossy compressions
I have not listened to mqa,but i have ripped cds and turned them to mp3s
and have listened (compared) the cd to mp3
and i can tell you very very little difference
also have listened (compared) hr/hd to cd with no difference at all!!!
(see on this page, LET'S listen PCM digital HR / HD, CD (3 min duration))
So to accurately test subjectively the mqa you need exactly the same recording
on the formats you compare

Have no time to investigate mqa further, and all i can say
smaller file sizes with good sound is the ideal audio file

Why digital codecs never stop coming

The pursuit of perfect digital will never stop
and audiophiles will never stop wanting that elusive perfect digital audio.
CD was a phenomenal!!!
Mp3 was a phenomenal!!!

Why analog sounds NaTuRal

The singer has a maximum unaided/unamplified dynamic range of say ~50dB
suppose ambient noise is 40dB,total loudness is ~90dB, but still human voice is ~50dB + 40dB ambient noise
Analog equipment have a dynamic range ~60dB
Very close to human voice dynamic range
Digital can make the human voice dynamic range as max as 96dB (cd dynamic range)
because they can also eliminate ambient noise etc, say 40dB,so human voice is ~96dB - ambient noise ~0dB = ~96dB

Now something unnatural is happening with digital,96dB human voice dynamic range
Absence of ambient noise etc
96dB voice, where human dynamic range (voice) is say ~50dB
very unnatural (superhuman!)

So, with analog we have voice=50dB and with digital voice=96dB
With digital is artificial. With analog is natural

Why Audiophiles are stupid

I remember in the 70s and 80s when all the rave was low distortion
audiophiles went for it big time thinking 0.001% makes a big difference to 0.1% subjectively
Nowadays is HR/HD digital files rave
and audiophiles now use amps with 5%,10%,20% amp distortions (tube/class-D etc) on HR/HD
How is that for a turnaround
History will repeat, in a few years HR/HD files rave will come to pass
and common sense people will use cd and mp3 files

Audiophiles get it wrong all the time
It's such a mess, nothing seems to sound good but their cables and fuses

The Four Pillars of High End Stereo

1) direction of sound
2) expansion of sound
3) dimension of sound
4) quality of sound
