MATRIX Audio X-SPDIF 24bit/192kHz USB Audio Interface DAC, made in China

Link: matrix-digi-usa

The X-SPDIF uses the X-Core 32bit/500MIPS microprocessor from XMOS. The X-Core is the most advanced USB to SPDIF converter available. It supports asynchronous USB playback up to 24bit/192kHz and is fully compatible with Windows, Mac, & Linux. Low latency ASIO/KS drivers are also supported.

The X-SPDIF is CNC machined from solid aluminum to provide complete shielding from interference. This ensures a bit perfect digital output.

The X-SPDIF has digital coaxial and AES/EBU outputs using a very high quality differential protocol line driver chip to achieve absolute signal integrity. The digital outputs are galvanic isolated from the computers USB ground to eliminate any possible ground loops.

The X-SPDIF utilizes a ultra low jitter dual-frequency clock consisting of two very high quality crystal oscillators. Since the clock has separate crystals for 44.1kHz & 48kHz all multiples of these sampling rates are perfectly and automatically reproduced (44.1khz = 88.2khz 176.4khz) & (48khz = 96khz 192khz).

Ultra low jitter is key in reproducing high quality audio and that requires an accurate and stable clock!

Polyvox (MiniMoog), Serial Number: 0986087, September 1986, made in USSR

Description: http://ruskeys.net

Polivoks is the portable electronic musical synthesizer which is designed for playing different musical compositions of any genre. It is also intended for creating some musical effects in cinema and play scoring, in studio. 

There are 4 octaves on the keyboard. The inclined desk is divided into the following functional sections: Modulator, Generator #1, Generator #2, Mixer and Amplifier. They give one a possibility to synthesize a broad spectrum of sounds and to change sounding at any time. 

There are 3 internal audible signal sources in the instrument: to broad-ranged of the Generators with changed form of oscillations and a noise generator for creating a non-musical sounds such as wind, surf, whine, etc. 

Possibility to connect an external audible signal sources to the synthesizer is provided for (e.g. guitars, electropianos and electroorgans). Sounds of different external sources are combined separatly in the mixer in any ratio. There is a filter in the synthesizer with cutoff frequency control and resonance to change colour of timbre of audilble signal over a wide range.

Revox 4641: In einschlägigen Hifi-Foren gibt es widersprüchliche Angaben über den Hersteller der Boxen. Einige behaupten, REVOX hätte die Boxen hergestellt, andere sagen, sie seien in Lizenz von HECO gebaut worden und seien baugleich mit der "HECO Professional P5000".

Dazu ein Zitat aus Hifi-wiki.de:

"Zweitgrößtes Modell aus der Serie P1000 - P6000/P6003 mit diversen Testerfolgen in der damals führenden HiFi-Fachzeitschrift "HiFi-Stereophonie". Die Box wurde mit gleicher Bestückung auch für die Firma Revox gebaut. Gehäuseausführungen Nußbaum natur oder Schleiflack weiß ... . 

... Bei 100% der Boxen dieser Baureihe sind heute die Originalsicken der Tieftöner bzw. Tiefmitteltöner zerstört, da sie aus Schaumstoff bestehen, ansonsten handelt es sich um langlebige und hochwertige Produkte von einem führenden deutschen Hersteller der 60er und 70er Jahre."

Technics SB-X3 Linear Phase Speaker System, 1978-79, made in Japan

Link: audio-heritage | hifiengine

39,500 (1 unit, around 1978)

A medium-sized speaker system of the SB-X series which realized the bookshelf type and linear phase design.

In order to realize Linear Phase theory in a bookshelf type, the SB - X series adopts a conical horn, and the midrange and the tweeter are withdrawn from the baffle surface.
In addition, the low range of each unit is smoothly enhanced by this conical horn, and low frequency distortion is also reduced by restraining this by a network, realizing low distortion of the system.

20 cm cone type Woofer is carried in low-pass.
This unit is a wide area unit with a high range extended to 5 kHz, and it has a high resistance tolerance design with heat resistance temperature of 200 ° C.

The 9 cm cone type mid range is carried in the mid range.
We are trying to reduce distortion by adopting a conical horn and also to improve the linearity at large amplitudes by paying attention to the shape and material of the edge and the material of the damper.

To the high region 2. The 5 cm dome type tweeter is carried.
The diaphragm adopts 15 micron ultra-thin titanium diaphragm, realizing high frequency characteristics and broadband. In addition, due to the ultrathinization, we added soft dome-like properties to the metal dome, and we are getting a good reverberation sound while suppressing peak occurrence.

In addition, the voice coil has heat resistance effect, adopting aluminum bobbin with good heat conduction, and realizing heat resistant temperature of 200 ℃ with heat resistant polyamide adhesive layer and polyester insulation layer.

Polyamide excellent in heat resistance is used for the voice coil adhesive layer of each unit, and polyester is used for the insulation layer. With this, we have obtained heat-resistant temperature of 180 ℃ ~ 200 ℃, achieving high resistance to input design.

Continuously variable attenuator is adopted as mid range and tweeter.
In addition, the tweeter is equipped with a thermal relay that protects the voice coil from excessive input.

Bass-reflex system is adopted for enclosure.
In addition, the front baffle has been decorated with silver metallic finish. I = 13> Bass reflex system is adopted for enclosure. In addition, the front baffle has been decorated with silver metallic finish. I = 13> Bass reflex system is adopted for enclosure. In addition, the front baffle has been decorated with silver metallic finish.
