Spectral SDR-4000SL

The Spectral SDR-4000SL



Ya es de madrugada, tras ver este Spectral puedo decir confiado: muy buenas noches.


Increíble reproductor de CD, descomunal. A mí que me disculpen, retrógrado o anacrónico no importa el adjetivo, pero en plena era de los servicios de audio (post descargas) y del tan mencionado HD (aún por comprobarse) yo sin duda alguna preferiría poner un reproductor como este en mi sistema y escuchar discos, es un pequeño monumento. No ofrece tonterías innecesarias, acabados de "dandy" o "playboy" ofrece lo que debe ser, ingeniería y refinamiento que descuella, impresionante en todo ángulo de visión y seguramente al oído, si no que desperdicio.

Admírenlo, Spectral SDR-4000SL

Onkyo CP-1050: una neva tornamesa para Europa únicamente

Onkyo | Onkyo Continues 70-Year Tradition of Hi-Fi Analog Sound with New CP-1050 Turntable









Continuing this rich tradition of Hi-Fi sound, the CP-1050 turntable features a super-smooth low-torque direct-drive motor that reduces low-frequency cogging noise. Another advantage of a direct drive is less of the high-frequency noise produced by some belt-driven designs, which use a fast-spinning electric motor.
 
The body is constructed from thick, vibration-damping MDF and the quartz-lock-controlled platter is die-cast aluminum for smooth, precise, and stable rotation. Together with the low-noise motor and rubber slipmat, the excellent solidity and weight of the deck combine to effectively reduce vibration for clear and open analog sound.
 
An aluminum S-shaped tonearm with detachable headshell and flexible counterweight system enables compatibility with a wide range of aftermarket cartridges between 5–10 g. As sold, the turntable includes a quality MM cartridge that contributes to an impressive signal-to-noise ratio of over 60 dB and wow and flutter of just 0.15% at 331/3 rpm.
 
A button on the top left of the deck changes rotation speeds to accommodate playback of both LPs and 45s (an adapter is included for 7-inch records), while four anti-vibration feet are height-adjustable to ensure stability on a variety of surfaces. The L-R phono outputs are gold plated and there is a dedicated grounding post to prevent hum. An RCA audio cable with earth and a detachable smoked acrylic dust cover are included.
 
The CP-1050 looks and sounds absolutely beautiful. It boasts simple versatility to fit into almost any existing Hi-Fi system with a phono equalizer built into the amplifier. As all Onkyo A/V receivers from the TX-NR636 and up feature a phono stage (the TX-NR838 and up with Pure Direct Analog Path to enhance sound quality of analog sources), owners of Onkyo-powered home theaters can also play their LP collections as well as experiencing everything Hi-Res Audio has to offer via the home network.

De esas cosas polémicas. Habrá que leer, enterarse y valorar las supuestas ventajas versus el precio seguramente más alto y más que nada probarlo en un entorno real.

La audifilia siempre llena de polémica y cosas peculiares

Muy pronto en una bocina cerca de tí: Endumax de Teijin



Dicho de modo rápido, le ha surgido una fuerte competencia al Kevlar.
Un nuevo material con aplicaciones muy interesantes para conos de bocinas es Endumax de la compañía japonesa Teijin. Vale la pena tenerlo en mente. Una muestra más que muchos de los desarrollos y avances no vienen de la mano de los mamuts corporativos del audio más procupados por fabricar barato y vender caro sino de la suma de pequeños avances por muchos otros.


Esto es Endumax:



Endumax – what is it
Endumax tape is a new, patented high-performance tape developed and made by Teijin. It can be used in a wide variety of products for various market segments – anywhere, in fact, where there is a need for superior strength, safety, light weight or durability.

For example, Endumax is used worldwide in applications and markets ranging from ballistic protection (armoring and bulletproof vests), ropes and cables to cargo containers, sails and even loudspeakers. The tape shape of Endumax allows for easy processing and seamless integration into the application of the customer.



Super-strong – and moreWeight-for-weight, Endumax is 11 times stronger than steel. But Endumax offers more than incredible strength. It is made of a special type of UHMWPE (Ultra High Molecular Weight Polyethylene), making it not only the strongest UHMWPE tape available in the world, but it also has a higher modulus and better UV resistance, creep properties and thermal-aging performance than other UHMWPE-fibers.



SustainabilityEndumax is the most sustainable UHMWPE product available, being made in an environmentally friendly, solvent-free process. As a result, the tape contains no additional processing aids or solvent residue. And the thermoplastic nature of UHMWPE means that it can also be easily recycled.



VersatileEndumax tape an be made in any width, depending on customers’ needs. In a special patented process, we also use Endumax tape to make a cross-plied uni-directional-laid sheet (UD). The result is a unique UD/cross-ply that can be consolidated to form plates of different shapes and thicknesses.

Para conos de bocina.







Endumax has excellent damping properties, so in combination with its high modulus and low density, it is ideal for use in loudspeakers.


Speakers of a specific size can be designed to reach higher frequencies and deliver more output for the same input power.

Stereo Amplifier CS2 - B.M.C. Audio



¿Qué tal esta belleza?







CS2-Inside







Unlike other amplifiers, a LEF amplifier handles a speaker's current demand separately from the voltage demand. The result is an unparalleled mastery of musical complexity that brings to startling life delicate details, rock-shaking power, high dynamics, sonic vitality, and accurate imaging — all on a three-dimensional soundstage.
Load-Effect Free amplification is a new experience that must be heard to be fully appreciated.
The CS2 also boasts solid output power: 2 x 200 watts into 8 ohms, and 2 x 350 watts into 4 ohms.
A fully regulated power supply with a 2kW toroidal transformer and balanced current capacitors provide the muscle behind the music.

Realistic Solo 4 un clásico de la recién difunta Radio Shack

Gracias a www.radioshackcatalogs.com podemos recordar ese universo de emociones y descubrimientos que era Radio Shack y que lo fué por décadas para muchos.

Una lamentable víctima más de la baja y repudiable cultura de consumo en electrónica que prevalece hoy día.

La Solo 4 fue uno de lso modelos de más venta en su tipo. Aquí una entrañable crónica sobre algunos aspectos de esta cadena http://www.cepro.com/article/rip_radio_shack_consumer_electronics_icon_in_memorium/

Hilter y el dilema audiófilo de cables y pruebas ABX





Bueno hay que reir un poco, primero de lo que ceemos y luego de lo que otros creen a fin de tomar un poco de balance y equilibrio y poder mantener la mente despejada, unos dicen, otos prueban, cada quien. 

Este video de la excelente "Der Untergang" ha dado para toda burla, parodia, crítica y simple chiste pero creo nunca imaginamos ver a un histérico Hitler hablando sobre audio, cables y pruebas ABX.

The Analogue Productions hace por fin justicia al SACD con relanzamientos Living Stereo de RCA | The Absolute Sound

The Analogue Productions RCA SACDs | The Absolute Sound


A tener en cuenta estos relanzamientos muy apegados al LP original de la aclamada serie Living Stereo de RCA y que ofrecen un mejor sonido con las virtudes también del sonido original explotando de manera debida e inteligente las cualidades del SACD y no como sucedió con los primeros lanzamientos de esta colección en SACD. Un buen trabajo por The Analog Productions.
