LINNENBERG ELECTRONICS

Welcome to LINNENBERG, manufacturer of fine purist high-end components. Since 1994 the company designs the most demanding digital and analogue circuits.  Unsurpassed circuit design plays the most important part in building true high end electronics capable of creating magic moments. We at LINNENBERG are in business for more than 20 years; our experience expands from chips to tubes and from rugged professional audio to delicate high end audio. LINNENBERG products are entirely manufactured in Germany. Each component is carefully hand-assembled. Quality control is assured by a rigorous testing procedure, as well as a meticulous inspection process.
 
Specifications are not the most important factor in creating fine audiophile gear. But strictly neglecting technical aspects isn’t the right way either. Our motto is to make every single spec at least 10 times better than what is actually required and finding a perfect harmony. It is absolutely worthless to offer a product, shining in one or two aspects, while failing to deliver in other areas. Yes, the human ear is always the final judgment, but not as a cheap excuse for flawed engineering.
 
SP1994
 
In summer 2014 we proudly celebrated our 20th anniversary. The POWERDAC from 1994 was the first product reviewed by stereoplay in September 1994. Motivated by distinguished artists, outstanding producers and mastering engineers like Doug Sax († 2015), Al Schmitt to name but a few, we always did our best to offer fine products to our dear customers capable of delivering a real great musical experience. Our promise for the future is to continue the good work.

The TELEMANN supports all high resolution music formats including DXD (352.8kHz/24bit) as well as a DSD 64/128/256/512 stream. 5x digital inputs plus optionally 1x analogue input provides flexibility for the source connection, whereas the balanced and unbalanced analogue outputs directly drive a power amplifier. Volume is adjusted in the analogue domain featuring a relay – resistor network using gold contact relays. In comparison to his predecessors VIVACE 1 + 2, the TELEMANN has even lower noise, lower distortion, and superior accuracy. Even with a standard 44.1kHz/16Bit source you will experience a crisp and clean sound never heard before. This is of particular importance because music from the major labels is obtainable in the CD format only. Higher data rates will give you more air and sparkle, while DSD showcases an even livelier and vibrant sound.

Femto master clock TJ < 0,0000000000001s
Digital to analogue conversion is carried out by the new ESS – PRO Sabre chip, regarded as one of the finest silicon implementations in the industry. This chip incorporates innovative circuits delivering spectacular music free from annoying artefacts. 4x balanced 32-bit D/A converter per channel pass over audio to our proprietary discrete analogue circuits. The femto master clock with a clock accuracy of under 0.1ps clock jitter makes this approach feasible.

Analogue volume control / preamp functionality
TELEMANN uses a highly sophisticated log. ladder network controlled by gold contact relays forming a constant impedance passive volume control preamp. Using this outstanding preamp functionality for an external analogue signal (e.g. phono stage) will make TELEMANN the last preamp you will ever need.

Digital filter with selectable characteristic
The user may select any from 7 filter options on the fly. Besides a standard PCM, high stop band rejection FIR filter giving the best performance on the bench, there are several other options to choose from.

Galvanically isolated asynchronous USB tranceiver
Any form of jitter in the incoming datastream is compensated by a small buffer. The audio data is clocked by a local high precision quartz master clock, eliminating all timing related distortions. Furthermore the transceiver circuitry is galvanically isolated from the rest of the DAC. The coupling capacitance between the two sections is in the order of a few picofarads. This eliminates effectively the noise interference from the host PC.

The LISZT monoblock power amplifier (200W @ 8Ω) brings together apparently conflicting attributes like, operating speed, current drive capability, stability in any load, lowest distortion and ultra low noise to name but a few. A key ingredient in achieving this difficult task is the fully symmetric operation from input to output and the high speed signal processing. It is the fast transient ability and ultra wide bandwidth (1.2MHz unfiltered) approach that let you hear the room, the ambience of the sound recording. Matching phase coherent speakers assumed, a pair of LISZT amplifiers will deliver a perfectly executed soundstage.

Strictly balanced architecture
The LISZT features a completely balanced architecture, with no back and forth conversion.  In consequence, two identical amplifiers are employed, one driving the speaker+ and one driving the speaker- terminal. While this doubles costs, it relieves the circuit ground from carrying the speaker return currents, resulting in a clean and unspoilt ground potential. The LISZT also offers a single-ended input, treated separately from the balanced input. A toggle switch located near the input jacks allows you to switch the amplifier between single-ended and balanced operation.

Ultra wideband design
The high quiescent current design of all preamp and driver stages enables a core speed close to 1.2MHz, slowed down only by input and output filtering to match real word requirements. With filters in place, the small signal as well as full power bandwidth (!) measures an impressive 400 kHz. The lower frequency limit is around 0.3 Hz. No coupling capacitors are used throughout.

Inherently low noise
High resolution audio is intrinsically tied to low noise and low distortion. System noise is the lower resolution limit of an analog system, because it determines the smallest signal not masked by a noise floor. Hence, low noise levels and thus a wide dynamic range are desirable. A-weighted output noise measures 40µV for the LISZT giving a SNR of 122dB or an equivalent to 20bit. 20 to 21 bits analog resolution is the realistic limit, dictated by the laws of physics.

Lateral MOSFET output stage
The lateral MOSFET transistor originally developed by Hitachi in the late 70’s is probably the only semiconductor power device solely made for audio use. Famous for its tube like characteristic and perfect bias stability under any load conditions, the LISZT uses a single pair of tandem devices in each output stage. The H-bridge output transistor array is energized by a heavy duty toroidal transformer running a bank of 120.000µF storage capacitors.
