THE WORLD'S ONLY
ACTIVE TUBE POWERED
This is among the world's finest cables! How can I make such a claim? One listen and you will know why. Active cables are dead quiet due to an electrical charge which is applied to the shield surrounding the signal wires. The shield acts as an electro-magnetic device, pulling in unwanted RFI/EMI pollution. Removing this pollution creates a black background which allows minute details which you have never heard before. Holographic is the best way to describe the effect. Three dimensional with exact instrument placement and the blackest background that you have ever heard, guaranteed!
Many audiophiles mistakenly believe that by using an active shield, the resulting sound is manipulated and will sound artificial and colored. Just the opposite is true. By surrounding the signal with an active shield you are preserving the intended signal with no outside interference. You will be surprised by how much electrical pollution is in the air once it is removed.
As you can see, the box houses an actual 12AU7 twin triode tube amplifier. It is powered by a DC-DC converter and the output of the tube amp charges the shield to about 50 volts. The tube amp samples the audio signal for it's input section and uses that signal to control the charge to the shield. What is created is a pseudo balanced interconnect, as the shield is effectively neutral relative to both conductors. Relative to the equipment ground, the shield sees half the signal voltage swing. Einstein would ponder the following question, what if the wires do not know that ground is ground? The results are stunning! 99.99% pure Copper twisted pair wires are used for a huge sound stage but still with great inner detail.
The unit is powered by a 500ma, 12v DC power supply. A 500ma power supply from any country can be used thus creating a cable that can be used any where in the world. Just plug in and get ready to be amazed. Just like your other tube amplifiers you can use different brands of tubes to fine tune the sound qualities. Tube rolling a cable? Fun Fun Fun!
I am so sure that you will be thrilled with this cable that I am willing to make a 60 day return period available during this introductory sale. If for any reason you are not completely satisfied, simply return for a refund minus shipping fee's.
The care that goes into making a pair of these cables is evident in the details and quality of materials being used. I have isolated every sound quality by many, many, hours of critical listening. From the solder, to the Rca connectors, to the wire being used, I know exactly what each element brings to the sonic table. It is by careful mixing of each harmonic ingredient that Aural Thrills Audio has arrived at this design. Please check out all of my unique products at www.auralthrillsaudio.com

THE TUBE POWERED INTERCONNECT IS THE BEST! I HAVE USED HALF A DOZEN
BRAND NAME CABLES OVER THE YEARS AND THIS ONE SURPASSES THEM BY A WIDE
MARGIN.SIMPLY MAKES MY ENTIRE SYSTEM SOUND MORE LIKE LIVE MUSIC.WHAT MORE
CAN ONE ASK OF ANY COMPONENT?
I have run your cables about 100 hours now and vastly prefer it to the not-too-shabby Signal Cable's Silver Resolution IC it replaces because of its superior, relaxed presentation. It makes listening to music more enjoyable at any volume level, but especially at low levels where much more space appears.
Again thank you for your work.
Comments: Interconnect safe in Sweden.Very easy transaction. The sound of my whole system changed to something,new and better by a factor ten. Nothing averable here in Sweden come close.
I received the cables, and as skeptical as I was when I purchased them, i thought, all it could be is a cheap trial. Well, I must say I am extremely surprised with the quality and the sound is so much better. The details of the mid-range and top end was brilliant, and the bass was more pronounce. This is one of the few cables that I have tried that handles any music you throw at it.
Great job and thanks.

For years I have wanted to get the Brass out of my cables. Brass is a terrible conductor and adds a real dullness to the sound. Silver is the best conductor followed by Copper and then Gold. Brass is way further down the list. The reason that RCA connectors are made of Brass is ease of manufacture as well as malleability. Conductive ability is not on the list of positives for this type of construction. ALL Rca connectors are made of brass and then coated with Silver, Gold, or some exotic metal to make you think it is a great conductor. The truth is that it is just Brass that has been coated, no matter what they advertise, Straight Copper, Silver, etc., would be far too soft and not hold it's shape. Finally, I have designed what I feel is the finest connector on the market.. PERIOD. It uses a solid, pure Teflon base that has been machined to accept a center pin and ground conductor. Teflon is one of the most inert substances on the planet. The Teflon plug surrounds the RCA connections on your equipment as well as the cable wires to insure a quiet, interference free sound. Getting rid of the Brass allows the use of super conductor metals which insure the pristine delivery of your sonic pleasures. Why make a cable that is painstakingly designed to deliver all information and then plug up both ends with a poor conducting Brass connectors? Why use 99.999% purity wires and then use Brass in the circuit? Brass is really just copper with impurities in it. There is more to a good cable than the metallurgy of the wire. This design features a Silver, center pin and a thin Silver return line to insure a minimal contact point. Silver has a sound of great detail, air and space. The thing that really impressed me the first time that I heard this design was the spaciousness and unbelievable detail. Next I noticed the black background. A product of the solid Teflon plug. These plugs sound as good or better than the WBT NextGen's which sell for $35 EACH. These plugs blow away and are more reliable than the Eichman Bullet. These plugs sound better than any Brass plug made! No one else has them.

What makes Aural Thrills Different?
The unique feature of Aural Thrills Audio is the fact that
ALL EQUIPMENT (except
sending components) in my reference audio system has been developed by me!
From the phono stage, pre amp, mono blocks and cables, to the final sound
of the speakers. Each product has been developed and tested by one person.
This gives me a unique understanding of the reproduction of sound. With
four years of college ear training, ten years as a professional musician
in NYC, and unmatched passion, I feel that I have the tools necessary to
create the finest reproduction equipment in the world. I have spent the
last ten years learning the intricacies of tube amplifiers. Every part.
Every wire. Every component. They all matter. Connecting all of this
equipment with compatible cables has become a daily obsession. As one of
my customers said, "I live audio."
In these days of endless loops of frustration, you can
count on getting a real person when you deal with Aural Thrills. No press
1, press 5, etc. You get a real person from the beginning. Someone who can
answer all of your questions. Emails are answered many times a day. Leave
your number and I will call back, really! With a 60 day, no questions
asked policy on all of my cables, you can be sure that your purchase will
work with your total system sound.
Lastly, it is my commitment to make sure that every product

face. Every order processed with the passion that only hand made goods can
deliver. I put my reputation on the line with every product I make. I try
my best to do all that is needed. I also try my best to keep prices
reasonable. Please consider that you are buying more than a
constructed product. You are buying my mind, my craftsmanship and my ears
which have worked on each component obsessively for countless hours.
Cable Design Theory
Aural Thrills Audio only sells
very special cables! Designed to provide your system with the ultimate
sound. They will not degrade the signal as many other cables tend to do.
Why? Our cables have been specially designed to provide a clear, deep
sound by utilizing solid core technology. Stranded wire has many points
where the wires touch each other. This creates a smearing effect as the
signal jumps from one wire to the other. The larger the wire, the more
this effect becomes evident. Research also shows that stranded cables
creates time distortions due to the uneven manner in which the signal
Next we must look at the wire size. I am
always amazed by the "oh wow" reaction of audiophiles upon seeing a very
fat cable. In true American fashion, the belief that if a little is good,
more is always better comes to mind. NOTHING COULD BE FURTHER FROM THE
TRUTH! The major portion of an audio signal actually travels as a wave on
top of the wire, much like a train travels on top of the tracks. A very
small part of this wave travels inside the wire. Since the wire actually
slows the signal down a time distortion is created between the signal on
top of the wire and the part of the signal in the wire. The best way to
minimize this effect is to use a small diameter wire so that very little
signal is traveling through the wire itself.
The third item in cable construction to
consider is the material surrounding the wire. Some companies use many
layers of coverings to convey the image of huge size. Again, this is not a
good thing. These layers act as huge capacitors for the signal. Capacitors
store and then release their energy. The result is a smearing and time
warp creating a cloudy sound. The cleanest sound is achieved by using
Teflon. Teflon will not absorb any of the signal. This means the total
signal arrives at the same time. None is released later causing
To shield or not to shield? In most cases
adding a shield to a cable takes away a little bit of the spaciousness
from the sound stage. Unshielded cables are great for Solid State
equipment using lengths of under nine feet. They deliver a spaciousness
and clarity of sound that most people find very appealing. When using Tube
equipment or cables over ten feet shielding is needed. The transformers of
tube amplifiers are gigantic EMI producing machines. Using an unshielded
cable with tube equipment will result in an induced hum. Always use a
shielded cable with tube equipment. Cable runs of over ten feet tend to
act as huge antennas picking up local radio stations. (RFI) To avoid this
you MUST use a shielded cable. Lastly, phono cables must be shielded.
Cartridges produce very small amounts of voltage. some moving coil
cartridges produce only .2mv. This low voltage is very fragile and must be
protected from your local radio stations which will overpower this
Cable Break In
All cables take a certain amount of time to burn in.
This may sound crazy but it is true. I have heard many theories for this,
but the one I tend to go with is the alignment of atoms within the wire.
It changes as the wire is subjected to electrical charges and ends up
aligning in the direction of electron flow. Most cable will sound good for
the first hour or so. Then they start to degrade. They become bright,
edgy, distorted, and closed in. The worst sound is at about 50 hours of
play. Slowly the sound will began to improve and at about 100 hours things
will start to really improve. The one exception to this scenario is Silver
wire which breaks in much more slowly. We do offer a burn in service using
the Hagerman professional model. It takes 48 hours to complete the
process. The cable is subjected to a frequency sweep which contains
signals above and below the frequencies of Human hearing. Although
additional break in is still required, this really speeds things up.
Amplifier Design Theory
I am committed to simple
designs which do not feature a lot of additional circuits. I love the
early designs. They tended to stick to the basics and did not add a bunch
of "correction" circuits. I have constructed and listened to most types of
tube audio designs. The more circuits that you add, the more they start to
sound like solid state. If that is what you want, why not just buy a Solid
State unit? My amps use the old designs but with an important twist, high
end parts. Modern capacitors and resistors are faster sounding, but still
retain the tube qualities we all love. The best of old and new. I usually
prefer tube rectification (changes AC to DC) but occasionally solid state
rectification is better. When developing these amps I always make each
version and listen. All Electrolytic Capacitors are by passed with film
capacitors to add extension.
Due to the length of break in I offer a 60 day return
policy on all cables, no questions asked. Just pay for shipping. I can offer this
warranty because I am so sure you will not want to part with this cable.
All cables carry an unconditional lifetime warranty to the original
purchaser. Just return to Aural Thrills Audio and we will take care of any
problems. Cables that have been abused or mistreated will be repaired for
a slight cost to be determined upon inspection. All amplifiers carry a 1
This is my pride and joy, no, my
obsession. As you can see, all components (except sending units) have been
constructed by me. This gives me a unique perspective on sound
reproduction. I am an avid record collector of 50's Jazz as well. I have a
good collection of the regular labels, Blue Note, Verve, Pacific Jazz,
etc. and also a bunch of not so well known labels and artist. You would
not believe how good some of these 50's recordings sound. Most were recorded with tubes so they just seem to sound right in my all tube system.
My system generally looks terrible. I am always trying new combinations of
circuits and design ideas. It's all about sound.
As you probably noticed, I
watch movies with this system as well. I really believe that the sound is
superior to five channel home theater systems. The soundstage is more
real, not manipulated and much closer to reality. A good Stereo VCR is
close to a record for sound quality. Rich, warm, just awesome Analogue. I
hate to admit it but I have become a fan of the musical.
The mono blocks are Aural
Thrills Audio 300B, push pull units. Each puts out a big 25 Watts but
still retains the beauty of the 300B. As you might expect, the filaments
are AC powered. PP configuration cancels out noise and the sound is big
and rich. These amps sound like the reason you wanted a tube amp to begin
The speakers are a very
efficient 96db. Max continuous power is 45 Watts. 25 Watts will blow you
out of the room. My love of early design, low powered tube amps led me to
these back end loaded horn design. The drivers are full range which
eliminates the need for a crossover. My theory for audio is always "less
The bass that comes out of
these speakers is unbelievable. The transmission line design is tuned for
50Hz. The sound coming out of the lower outlet is also delayed a little
bit. This creates a wonderful ambience for Jazz and Classical. These
cabinets have been constructed of 1" Baltic Birch Plywood. A very dense,
slow growing species imported from Russia. Unlike normal plywood, any
voids in EACH layer are cut and filled with a plug. You can see that there
are no areas without wood, on each layer! The speakers weigh about 175
pounds each. As is the case with a single driver, imaging is spooky. Final
finish will be done soon
A VPI TNT with speed controller
mounted on a Lead filled VPI stand is the basis for all of this great
sound. A Graham tone arm is used. I love this arm. It is very easy to
mount a cartridge and alignment is accomplished to an amazing accuracy. I
usually use Low Output MC cartridges. Mounted now is a Benz Gold. A very
nice cartridge for the money. The table is connected to an Aural Thrills
Phono Stage by an all Silver Aural Thrills tone arm cable with five pin
Cardas connector. Next the Phono stage is connected to a Two Stage Cathode
Follower pre amp of my design by a pair of Aural Thrills Bass Boss cables.
Output to the 300B mono Blocks is handled by an Aural Thrills, Tube
Powered Active cable. All amps are connected directly to a dedicated line
by Aural Thrills 10awg Power Cords.
