TAS Phono Amp Of The Year

Save $200.00

Phono stages are very special to me. I have a large record collection and
never made the switch to digital. I had a field day when everyone was
selling their records to Goodwill. $1 each. I fear these good old days are over
as others are discovering the magic of vinyl. I have been building phono amps for
many years and have tried many and built many others  My favorite is to use
tubes for all of the amplification. The main downfall of this approach is that
tubes can be noisy. Phono amps multiply the signal many times over. Much more than
other types of amps. Noise is multiplied as well. So what is the solution? I
use a modern power supply which is voltage as well as current regulated

The transformer type and size is also a huge consideration. Not only do the
different types sound different. Each has a certain noise it emits. I use a Torrid transformer
They are more quiet and linear than other types. They cost more, but are worth it in sound
quality. You may need to utilize a head amp if you are using a cartridge of less than .4mV if tube noise becomes objectionable. Please visit www.auralthrillsaudio.com to see all four award winning phono
amps.NICHICON MUSE


KG Series



Datasheet



 
Nichicon KG Series, designed for high-grade
audio equipment, offers three sound quality variations.




Features

 


  • Capacitance range 680 to 33,000µF
  • Voltage range 16V to 100V (Type I, Type II, and Type III)
  • Temperature range -40ºC to +85ºC




These are awesome and make electrolytic capacitors
sound deep and rich. Four supplied 12ax7 tubes provide plenty of quiet
gain.
All traces on the board are made of Silver for detail and power. I
have built and listened to at least 10 different circuits until I
settled on this one. Because of the feedback RIAA circuit It has that
you are there quality.
All Parts are hand selected to insure a large soundstage. Every power circuit in this amp is
voltage regulated and the power circuit is also current regulated.  This
regulation makes the unit especially quiet.

 



NOW WITH MUNDORF CAPACITORS



The film capacitors used in this model are the great sounding new Mundorf MCap Evo. These film
capacitors are some of the best sounding around at this or many other price points.

 


PRP RESISTORS


These well know audiophile resistors sound great. I have used them
exclusively for over ten years. They have a nice warm well defined sound. All PRP capacitors
are rated at 1% of their value. This creates two equal stereo circuits when
results in a superior soundstage.


 


HOW CAN THIS AMP BE ANY GOOD AT THIS LOW
PRICE?

 



As you can see, I have not spent a great deal on the cosmetics of the unit. No fancy case, no fancy
knobs, no fancy finish, only quality parts. I have used parts from suppliers all over the world.
Included are parts from Japan, Germany, China, and USA to keep costs down. I have used a
standard chassis instead of paying hundreds for a custom job with printing. You will not find
this unit anywhere else. It may be the best deal in the audio business. Most people do not know that you can buy film capacitors from $.98 to $150/ea. and more for the same value.
Capacitors make one of the most profound effects in amplifier performance. I use the
very well regarded Mundorf Evo Cap in all positions. Great performance
at a decent price.

    Just wanted to let you know I received the unit in great shape. I am leaving in the morning on vacation
    and won't get to listen much until I get back. From what I have listened so far, all I can say is awesome,
    awesome, awesome. I will just rotate my Moving coil cartridges. I have some older preamps for MM.
    Other cartridge Ih ave is Low output moving coil Grado Sonata. Haven't tried it yet.
    Thank you for everything. Don't know what brand of tubes are in it, but they sound excellent to me.
    David.



    Hi Tom,
    I changed the setting back to M C @ 100 ohms after trying a higher setting,I
    took the sot out of the configuration, I warmed the amp up with one side of
    Bach and then I played my reference album, Dark side of the moon.


    HOLY MOTHER OF GOD this would equal  the most discerning systems at any cost,
    the separation and darkness of the sound stage just blew my mind I am not
    changing the cartridge, it could use a little more mv output to be perfect but
    it is not worth the effort as this turntable is a bear to change. Thank you
    for leading me away from the H O M C, I did buy the denon 103 r and I am going
    to install that on a Thorens 160 that is being refurbished and up graded with
    todays technology or possibly a VPI classic if I can get the right price on
    that and sneak it into the house so my wife doesn't see it.


    At any rate I could not be happier with this very fine pre amp you would be
    hard pressed to find one that functions as flawless at any price. It is a
    great product and you are a absolute pleasure to deal with.


    I will send you the tracking # when I go to the post office, but now It is
    Beatles time

    Good afternoon Tom,
    The preamp is here and I must say I am quite impressed with the
    build quality and construction of piece. First rate and it looks
    great in the rack. However looks aside after plumbing it up into
    system the real proof of your Phono pre with the balanced outs
    is what really matters to me!  After listening to a MFSL Rolling
    Stones “Let it Bleed” I was quite pleased, then on to Stealy
    Dans “Aja” I  was rapidly becoming an Aural Thrills Audio fan
    big time. The punch combined with a subtle smoothness is
    magnificent. Lower register notes on piano are outrageous clean,
    tight and dominate. I am fully aware how difficult it can be to
    accomplish this as I worked my tail off with Leon Russell’s
    engineer one evening getting this very thing “right” at a show I
    produced and engineered some years ago. Thank you for your
    devotion to what matters in your craft. Perfection takes its
    toil on the less passionate but their always will be folks like
    me that understand and appreciate folks like you. Now on to the
    Beach Boys “Pet Sounds”

    Thanks Again

    What Makes Aural Thrills Different


    Check my feedback on both Audiogon and Ebay, 100% POSITIVE over twelve years!


    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!


    Lastly, it is my commitment to make sure that every product
    is made to my standards. Every product guaranteed to bring a smile to your
    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
    travels.


    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
    distortions.


    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
    miniscule signal.


    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.


    I want to talk about amplifier
    test numbers.  I am aware that this is a delicate subject which can
    sometimes lead to hostilities. I must tell you that I am not the
    engineering type. I design and build my amps much like I played my
    Trumpet. I was taught music theory and after teaching my ear to recognize
    what the theory sounded like, I never thought of theory again. I have done
    the same in amplifier design. I know what each circuit sounds like. 
    I have built and listened to them using the electrical theory that I have
    learned. After hearing what each theory sounds like, I no longer want to
    talk theory. I only want to talk sound. 


    Watt Wars


    The early amplifiers were somewhat low in power. Only a
    few watts. Many different types of tubes were used and each had its own
    charms and weaknesses. Soon, amplifier makers found that customers were
    power hungry. The war was on and nothing will ever stop it. If some is
    good, more must be better. It is American as Apple Pie. In the quest for
    more power I feel that certain intangibles were lost. The simple beauty
    and clarity of a few watts were slowly, a watt at a time, changed to brut
    force power. Even non audiophiles could hear the difference. I think they
    got it right the first time.


         

    My Laboratory

    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
    with.


    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
    is better."


                        

    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.
