DMSD 60 Speaker Decoupling System

€570 - 8 decouplers


The DMSD 60 Decoupling System has been developed with both the Studio and HiFi user in mind to provide an effective, professional grade speaker decoupling solution.

Designed and manufactured in Naples, Italy by Dave Mastrodonato Studio Design, DMSD 60 Decouplers are crafted using the highest quality aerospace grade materials, which have been carefully selected based upon Dave Mastrodonato’s prior two decades of industry experience.
His ultimate aim, to create the most effective and versatile speaker decoupling solution on the market.

DMSD 60 Decouplers unique construction significantly reduces sound energy transmission from speaker cabinet to supporting surfaces during audio playback.
This has the effect of dramatically improving perceived low frequency precision and tightening the stereo image, therefore providing an aural representation truer to the speaker manufacturers intended design.

Whether it be a critical listening environment or an audiophile’s home audio system, DMSD 60 Decouplers revolutionise the way way audio is experienced, creating “A different vision of sound.

Silbatone L-103

The L-103 uses two silver input transformers, then a 24 step autoformer volume control, with a WE 310A triode stage directly coupled to 7044 tubes driving a single core Finemet silver-wired transformer. Five unbalanced line inputs and balanced or unbalanced output.

Avid Sigsum integrated amplifier

With built-in phonostage and four line level inputs, Sigsum like Celsus uses the ALPS RK50 volume control

Avid Celsus Pre & Power amps

The Celsus pre-amplifier incorporates a phono amplifier within a fully balanced design and offers the same flexibility found in the company’s Reference Pre-Amplifier.

For example, there’s the ability to simultaneously connect two phono cartridges and an additional four line level inputs.

The ALPS RK50 volume control used in the Reference Pre-Amplifier is retained and a separate PSU is included.

The matching Celsus stereo power amplifier has a direct lineage to the Reference Stereo amplifier design.

Plinius RM-10

RM-10 marks the flagship electronic designs and the highest level build quality of stereo preamplifier housed in a new aesthetic design.

The RM-10 will be closely followed by Class A Power Amplifiers RA-300 and RA-125.

Key features of the new RM-10 Stereo Preamplifier:

New Discrete Circuit Design using only discrete components for lowest possible noise and distortion figures.

Analogue Balance Control for accurate adjustment of the audio level.

High Performance HT Bypass eliminates additional balanced/single ended signal processing and passes the signal through the high quality line amplifier stage.

Adjustable Line Stage Gain allows the adjustment of either the standard 12dB gain or a lower noise 0dB gain setting.

Dual Mono Configuration ie. a dedicated transformer and power supply for each of the left and right channels allows complete isolation of the signals and importantly the ground reference paths.


Specifications:

Line Inputs: 3 x XLR/RCA selectable, 3 x dedicated RCA
HT Bypass: 1 x XLR/RCA selectable
Line Outputs: 2 x XLR/RCA
Connectivity: 1 x Trigger In, 2 x Trigger Out, 1 x RC5 In
Gain: High: 12dB (4x), Low: 0dB (1x)
Input Impedance: 10K Ohms
Height: 170mm (6-3/4”)
Width: 510mm (20”)
Depth: 520mm (20-1/2”)
Weight: 20kg (44lbs)

ALLEGRO delivers the superiority and authority of a linear class AB amplifier - even in demanding applications. It features high current capability and operating speed not to be found in IC-amplifiers aka “gain-clone” or any class D design. Clever construction techniques enabled us to build an amplifier with high packing density, consequently making the signal and power paths extremely short. So, don’t be fooled by the tender look – it is part of the concept to get big sound. In fact, creating circuits with unrivalled speed and response time is amongst other things a matter of physical closeness of electronic parts. The higher the frequency, the more it is important to reduce every millimeter of board trace.


Lateral MOSFET output stage

The transistor originally developed by Hitachi in 1977 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 ALLEGRO uses just a single pair of tandem devices in the output stage in the so called “common source” arrangement.


Balanced signal path

Almost any LINNENBERG (past / future) product features true balanced circuits and connectivity. Historically, this may have a reason in our roots lying in professional audio. ALLEGRO is no exception: here, the circuit composes of a very low noise instrumentation amplifier such as used in high-precision measuring equipment. This approach ensures perfectly matched input conditions for the positive and negative signals and thereby allows the realization of high-performance balanced signal transmission.


Ultra wide band design

The high quiescent current design of all preamp and driver stages enables a core speed close to 1MHz, 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 350 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 distortion. System noise is the lower resolution limit of any analog systems, because it determines the smallest signal not masked by a noise floor. Hence, low noise levels are desirable. A-weighted output noise measures 25μV for the ALLEGRO giving a SNR of 120dB or an equivalent to 20 bit. 20 to 21 bits analog resolution is the realistic limit, restricted by the laws of physics (e.g., thermal white resistor noise).


Miscellaneous

The power supply consists of a 230VA toroidal mains transformer and a total of 60.000μF energy storage capacitors, enabling a stable output of 55W/90W at 8Ω/4Ω. Precision regulated supply voltages for preamp and driver stages. Microprocessor controlled – non intrusive protection circuits against over current, DC-offset or over temperature.
