| Why might you care about Analog vs. Digital audio? |
 We
live in an analog world, the human ear hears music as analog. The
wires that drive speakers carry analog signals. Analog signals have infinite possibilities. Digital music
signals are discrete or finite. Audio CDs store the music digitally.
Turntables generate an analog electric signal from the vinyl record. |
 Speakers
receive analog signals to move air. Electro-magnets push those
speaker cones against opposing magnets that act like springs. Very
fast and strong changes in the electrical input moves the cones for
the natural sounds that we enjoy. Good woofer speakers are
large, heavy and literally create a breeze around them. Strong
powerful amps are needed for great sound (even at low volumes). |
 Turntable
needles vibrate from the grooves in the record. This vibration then moves an
electrical coil which produces
electricity as an analog signal that gets fed into an amplifier.
Vintage analog amplifiers do not digitally enhance or change the
pure analog signal coming from a turntable heading to the speakers. |
 Great
Amplifiers and Receivers need large electrical transformers and
capacitors to be able to generate very fast and powerful signals to
the speakers. Vintage stereo receivers and amplifiers are very
'Heavy' and have no 'microprocessors or chips' just old fashioned
electrical components, which is exactly what analog signals needs.
These large components kinda give them torque in addition to overall
power. Most Surround Sound Receivers do not have these Heavy
Components for premium sound quality. |
 Much
of our music sources are digital. Digital
sources compress the file / download size which greatly lowers overall
sound quality, so the source of the digital music is very important.
The other consideration is what component is converting the digital signal
into a analog signal to input into your amp, it's the 'DAC' Digital
Analog Convertor. A computer, laptop, tablet, phone or Bluetooth
device might use a $0.25 microprocessor chip to serve as the DAC,
you will want a better DAC then what these provide. |
 Direct
to Disc Albums: D2D These are awesome! Typically they are made by
recording thru all analog mixing consoles and then direct to the
'lathe' that records the actual vinyl master album. The music never
goes to tape or digital recording for later mastering, the recording
is made without multitrack recording, mix downs and overdubs, just
mixed live for stereo. Spontaneity of performance is preserved as
the entire side of an album is a non-stop continuous performance. We find the sound quality
of these D2D albums to be awesome, super high highs,
super low lows and excellent stereo separation. Excellent examples would be
"Les Brown and his Band of Renown", "Benny Goodman the
King" and "California Smoker". D2D is a real treat for your ears. |

Digitally
Remastered Albums: Back in the 70's and 80's lots and lots of
people listened to FM radio, FM modulation has distortion and
quality problems with really high notes and really low notes. So
when albums were produced and mastered back in those days they would
intentionally back off on the treble and the bass to make the album
sound better when the DJ at the radio station would play it over the
FM airways. Mass production would also degrade the quality of the
albums. Therefore these recently 'Remastered' albums provide
higher highs and lower lows then the original album did. Currently
you can buy the Fleetwood Mac Rumors album as Digitally Remastered
onto (2) 180gram albums running at 45rpm providing very high
fidelity.

 Digital
Music and Streaming sources: Digital
sources compress the file / download size which greatly lowers overall
sound quality, so the source of the digital music is very important.
Listed in order of quality: POOR - YouTube, iHeart,
Pandora, Amazon, Apple, Google Play, Spotify, Tidal - BEST.
Of course many of these have the free service and then a
pay / premium service that can provide better quality. We use the
Spotify Premium service at $10/month and with the computer 'desktop'
application and they give us very high bandwidth downloads. |
 Bluetooth
Receivers: These connect to any stereo amp/receiver and are
available for as little as $25. Bluetooth receivers have common
Red/White RCA analog output connections to be plugged into your
amp/receiver AUX or Tape In port. Your Laptops, Tablets and Phones
simply connect to the Bluetooth Receiver wirelessly within about 20'
into Vintage and/or newer amps/receivers. However, consider our
comments about DAC and consider a good Bluetooth receiver at about
$100. The Harmon Kardon BTA 10 at $80 does an excellent job both
with it's Bluetooth reception and it's DAC function. AND by the way
Computers, Laptops, Tablets and Phones can be directly plugged into
your amp/receiver AUX or Tape In port using a 3.5mm (headphone jack)
to RCA cable !!! |

More
info on the 'DAC' Digital Analog Convertor. A computer, laptop,
tablet, phone or Bluetooth device might use a $0.25 microprocessor
chip to serve as the DAC and they do a very poor job. The 'analog
headphone jack' on these devices is very low quality! For computers
and laptops there are USB devices like the 'DragonFly DAC' starting
at $100 that provide excellent DAC functions. We use a DragonFly
Black on our Spotify Premium computer and get 96000 Hz (an Audio CD
Disc runs at 44000 Hz). If you are sending the digital music signal
over Bluetooth it remains digital until it reaches the Bluetooth
receiver and the Bluetooth receiver is then the DAC with analog
output into a amp/receiver, so a good $100+ Bluetooth receiver can
really improve quality. If you use the
HDMI port out of a laptop into a surround sound receiver, the signal
remains digital until it reaches the receiver and then the
receiver becomes the DAC and can do very well. Audio CD disks store the music in a digital
format. If you are using a Audio CD Player connected to the
amp/receiver using the analog White/Red RCA cables then the CD
Player is doing the DAC so a better more expensive CD Player should
sound better. If the CD Player has Digital/Toslink/FiberOptic cable
output going into a newer amp/receiver with this input then the
amp/receiver becomes the DAC and could increase sound quality.

 Surround
Sound Audio Video Receivers AVR can vary greatly in 'Stereo Sound
Quality'. Typically they are loaded with features like their claimed
high wattage, internet connections and so on, but often lack in
actual sound quality. We have used many different AVR models and
have found some tips to really help you. If your main priority is
good stereo sound, but you also want to great sound from your TV,
all you need is a Center Channel speaker for TV vocals and a good
pair of stereo speakers. You do not have to have rear surround
speakers. And if you don't want a sub woofer the AVR will send the
bass to your main stereo speakers. Most AVR units can provide all
you want with just these (3) speakers, and you can always switch it
to a Stereo mode for the best sound from your main speakers. |
