The best sound in Munich

Zellaton Statement with the team.

Cypher Labs Prautes headphone amplifier

Designed by Coffman Labs and produced in collaboration with Cypher Labs, the Prautes is a limited edition analog headphone amplifier.  Combining vintage tubes, military technology, and hand made American components, we’ve sought to unlock an unsurpassed listening experience for the audio customer at an affordable and inclusive price.

Primarily intended for headphone use, the Prautes drives a wide range of headphone types and provides for impedance matching. It includes a very subtle bass boost feature, a line-out stage, and is also capable of powering small speakers. The controls are optimized for headphone output to offer revealing clarity, presence and an expansive soundstage—presenting your music with subtlety, image, accurate detail, and the excitement of live experience. The result is a legacy piece that is timeless and enduring.

The Prautes uses a 12AU7 tube gain stage to drive a pair of 50L6 or 25L6 tubes (note in product serial number) in push-pull mode. This provides for more power than needed for almost all headphones—and can drive high efficiency speakers with about 2 watts. Five separate output impedance settings are provided to match listening equipment, including 8 ohm speakers, standard headphones, high impedance headphones and In-Ear-Monitors.

Boulder 508 Phono Stage

The 508 is the smallest, least expensive product in our product range and punches well above its weight, drawing its basic design from the iconic 2008 Phono Preamplifier.

Everything about the 508 points towards design efficiency: a chassis machined from a solid block, compact surface-mount design, a single pair of balanced inputs and outputs, a single RIAA EQ curve, simple MM/MC switching, and more.

Merrill Audio Oganesson Power Amplifiers

Connecting you to your Music so deeply they will touch your soul, that is the new line of the most advanced Power Amplifiers from Merrill Audio. This Crowning achievement took over 4 years of research, the use of the very latest technology, meticulous engineering and finest materials available. Using Merrill Audio’s proprietary ZXOL design, the new ELEMENT series of Power Amplifiers are an order of Magnitude better in every sonic character than their previous amplifiers and simply like no other and

A great many new technologies are used in the new ELEMENT series, code name Project Oganesson. This is named after the Oganesson element – the latest Atomic element added to the periodic table, OG with atomic number 118. The ELEMENT series of Amplifiers will start with the ELEMENT 118, as with Og 118, and continue with ELEMENT 116, ELEMENT 114 which will inherit this technology and advances in audio reproduction.

Using a zero feedback, open loop proprietary design, code named ZXOL from Merrill Audio, the Power amplifiers get the most details available and the fastest response. The open loop design takes advantage of the very latest exotic transistor technology using Gallium Nitride. Extracting and keep this accurate speed and huge amount of detail in the musical reproduction required a circuit board that has almost all its parasitic inductance and capacitance reduced to near zero. Using expertise developed over a decade the extra special Circuit boards were designed and a unique pure copper onboard heatsink for very fast thermal transfer and stability. The pure copper heatsink the power supply and amplifier weighs a hefty 16 pounds. Only the finest 0.1% tolerance components were used. Even the wire was specially selected silver plated OFC Teflon sleeved wire.

Live Music has both immediacy and power. Both require the power supply of a power amplifier to appear as an unlimited, immediate resource. Merrill Audio uses an LLC design for its power supply where a custom built transformer is designed as a precision inductor. With this design the power supply can instantaneously supply almost any current. The combination is the most revealing, fast, and exciting music reproduction you will hear, and will simply draw you emotionally into the music with its realism, clean, ultra-quiet background. All this is packaged in the ELEMENT 118 Power Amplifier Monoblocks. Beautifully engineered chassis that is accented with Rose Gold Acoustical Dampers and faceplate. A touch screen for ease of use and information is provided on the front. For your ears and your eyes.

The ELEMENT 118 Power Amplifier Monoblocks, has a huge reserve of power for extended transients, delivers very musical 400 watts into 8 ohms, 800 watts into 4 ohms and 1,600 watts into 2 ohms. Dual pure copper WBT speaker binding posts provide easy bi-wiring. 20A IEC AC inlet is used for a tight, excellent connection with heavy power cords. The ELEMENT 118 Power Amplifier Monoblocks are Acoustically isolated on Stainless Steel Outriggers on GAIA footers from Isoacoustics.

See the World premiere of the ELEMENT 118 Power Amplifier Monoblocks, priced at $36,000 from Merrill Audio at the Munich High End Show Atrium 4.2 E226 Room. Feel the emotion so deep it will touch your soul.

It has AES, COAX, BNC and Optical Inputs, that accept PCM 192/24 and USB that accept PCM and DSD files. DSD files are routed to a dedicated converter.

Also there is an I2S Input with HDMI connector.

The analog stage uses a single-ended tube transformer coupled at its output. Includes a remote control.

DAC1000 SE

In the Silver Edition the resistors for the R2R are custom made naked foil resistors with virtually no drift with temperature and output transformer windings are with silver wire

Audio Consulting Silver Rock OPT NOS DAC

There are a lot of opinions that analogue is better than digital sound.

It took us some decades to achieve analogue front ends that really show what can be revealed from LP’s.

Our customers and us are really surprised by what can be heard on Vinyl, despite the obvious mechanical limitations.

Provided the recording is of good quality, there are lots of musical emotions to be had.

Provided the recording is of good quality…why this can be a problem is marvellously described in Greg Milner’s book: “Perfecting Sound Forever: The Story of Recorded Music”.

There must be a reason why we always end up listening to LP’s from the late 1950ies or early 1960ies, some even mono…

What has happened to the sound in the 1970ies, 1980ies, 1990ies?

Well you have to read Greg Milner’s book.

Starting in the 1970ies with the first digitally recorded masters and LP’s that were produced out of it, we were told that digital was “perfection”.

That was even more so when CD became available in the early 1980ies.

Unfortunately this was not the case and digital sound became famous for: “harshness, lack of harmonics, lack of decay etc.”.

Even today we tend to say that this “particular digital” front end is so good that it almost sounds “analogue”, meaning that analogue still is the reference.

It took us over 30 years of research here at Audio Consulting in order to understand why CD players, flash card readers and DAC’s may sound so boring.

And it is definitely not enough, just to add a tube output stage in order to compensate for it.

The DAC that we have developed is a very special one…

Of course it is fully battery powered (4 batteries in fact), of course it uses a Silver Rock output and amplifying transformer, and of course it uses non-oversampling technology.

What is the result?  Well what do you expect us to say?
Try to listen to a system using it…

For those who believe in technical specs, here are a few:

16bit / 44.1 KHz; 24bit / 96 KHz; 24bit / 192 KHz compatibility
Four batteries are powering the circuits
A non feed-back buffer stage is driving the gain and output Silver Rock transformer
Internal wiring using our silver wire with cotton tubing
Assembled using our custom made 10% silver solder Mundorf CH Precision
XLR output connectors available instead of RCA at no extra cost
Absolute phase switch available at extra cost
Price:  CHF 28’500.00 , with absolute phase switch CHF 31’000.00
