Si desde un Sony u Oppo de 300 USD hasta un Mark Levinson de 22,000 estan en capacidad de reproducir discos SACD la pregunta forzosa es ¿ Si el equipo esta ahi cual es el probelma entonces para que este formato levante el vuelo ? En este momento no tengo a nadie mas que culpar que a la quejosa industra grabadora.
Veamos ahora este otro magnifico reproductor SACD de la emblematica T+A de Alemania

High performance mains power supplies with vast current delivery for analogue and digital sections.
Consistent two-channel sound
The SACD 1250 R is a pure-bred two-channel player which we have developed for the purpose of obtaining the highest-quality stereo reproduction from CD and SACD. The T+A philosophy of audio playback is unique: each music format has its own independent signal processing section with clock and data resynchronisation for jitter reduction. This process was developed ten years ago by T+A, and synchronises the converter’s clock signals perfectly with those of the disc mechanism. There are even different oscillators for CD and SACD.
No-compromise design
A crucial factor in the superb overall results of our players is the thorough, ingenious overall design and construction of all the individual sub-assemblies. Signal paths are extremely short, minimising interference influences and cable losses. The mains power supplies for the digital and analogue sections are strictly separated in order to avoid any induced interference between them. Both sections are extremely stable under load, and the analogue power supply is even based on a toroidal transformer. Each stage of the power supply features multiple stabilising measures, and all sub-assemblies are separately encapsulated and shielded.
Bandwidth switching
SACD discs deliver a much higher bandwidth, and this can cause severe problems with amplifiers of moderate quality. One solution for us would have been to limit the frequency response of the player to the lowest common denominator, in order to cope with amplifiers of modest quality, and this would certainly have been the safe route. However, we were not content with this, so we decided to equip the SACD 1250 R with a pure analogue output filter whose bandwidth can be switched between 60 kHz and 120 kHz. By this means it is possible to set up the player to match any amplifier very accurately, and there is no need to forfeit anything in terms of frequency response and phase linearity where a good, wide-bandwidth amplifier is used.
The converter
The SACD 1250 R is a thoroughbred two-channel CD / SACD player, i.e. it is designed and built specifically for purist fans of stereo reproduction, and contains absolutely no video components. Its counterpart, of identical construction, is the SADV 1250 R HD: this is a six-channel (multi-channel) player capable of reproducing top-quality two-channel audio as well as multi-channel audio from CD and SACD.
A common feature of these two superb players is the unique and extremely sophisticated D/A converter board / analogue board. Burr-Brown D/A converters are acknowledged as the best in the field, and no fewer than eight carefully selected units are used in each machine, although they are used in different ways in the SACD 1250 R and SADV 1250 R HD.
In the SACD 1250 R four of these converters are used for each channel in the form of our T+A quadruple converters, a further enhancement of the differential converter, which has been considered the last word in circuit design until now. The ground-breaking quadruple converter allows the machine to achieve values for total harmonic distortion, signal : noise ratio and dynamics which are genuinely extraordinary. The outstanding test results from all over the world concerning these players’ predecessors - and the D 10 player, which features the same technology - are sample proof of the superiority of this unique design philosophy in terms of sound quality.
A programmable 56-bit signal processor is employed to provide faultless digital control of the converter units, and this, in conjunction with the superior T+A oversampling algorithms, ensures that the player is able to exploit the full performance potential of the D/A converters. The listener can choose between no fewer than four selectable mathematical processes for the eight-times oversampling: from the conventional FIR (highly linear frequency response) to T+A Bezier polynomial interpolation with its unexcelled timing precision; the latter sounding extraordinarily authentic and “analogue” in character. These two sections are strictly separated galvanically by the latest iCouplers and opto-couplers, to prevent any danger of the digital section influencing the audiophile analogue section.
