Classe SSP-800 新AV前级
[attach]138872[/attach]
Introduction
From inception the SSP-900 project had but only a single agenda and that was the creation of the ultimate audio and video processor with little regard to cost. The many years that went into the research and development exercise finally culminated in a statement product that was on the verge of release in early ‘07. Unfortunately, the over engineered SSP-900 was based on an extremely complex modular design and was very expensive to build.(Street price was originally set for $25,000).
Achieving quality product yields from volume manufacturing was no trivial task not to mention the product lifecycle that would be necessary to realize a timely ROI. Furthermore, the concept went beyond Classe’s core competency of producing strictly high-end audio components. Rather than market the SSP-900 as it was originally envisioned Classe’ rechristened it as concept vehicle for creating the SSP-800.
By reducing the modularity of the SSP-900 and stripping it of its video processing boards, the SSP-800 would be half as expensive, easier to build and more reliable. Since most of the R&D work had already been done in the creation of the SSP-900, the SSP-800 only needed to be adapted to the newest hardware standards and consumer needs at the time. Additionally the slimmer SSP would have much greater market appeal catapulting the Classe’ brand name for quality and performance to a wider audience.
Audience
The SSP-800 is simply put a high performance multi-channel audio processing machine. It caters to people that put audio reproduction above all else. It is not in competition for the logo’s title and it is not seeking the most features award either. Classe’ built the SSP-800 for one purpose and one purpose only and that is to deliver the best audio playback possible. Anyone looking for a conversational piece decorated with ridiculous graffiti logos and silly features that are likely to go unused or underutilized should probably look elsewhere. The SSP-800 is a high-end definition product that is all about getting the most from your audio sources, no more no less.
Advantage
The SSP-800 is engineered from the ground up by the Classe' Design Team that built the acclaimed SSP-600 and by the principle engineer that brought the Proceed AVP2/AVP2+6 and the cost no object Mark Levinson Nº40 Media Console to market. The AVP2/AVP2+6 is recognized as one of the best processors ever made inheriting much if not most of the Nº40 Media Console's DNA. The SSP-800 result’s from the ultimate culmination of talents between Classe' engineering and Proceed/Mark Levinson heritage. The SSP-800 makes no compromises and is the evolutionary next step in high-performance multi-channel audio for both analog and digital sources. (Note: The AVP2+6 originally retailed for $6,895 and the Nº40 Media Console $30,000, circa 2002.)
************************************************** *****************************
Price: Originally $10,000 -12,000, Now $8000
Availability: As of April 28th
Dealer Shipments: Originally March, Now May/June
Customer Delivery: Originally April, Now June/July
Status: A two week delay was incurred trying to resolve two issues on the video board but all the hardware looks great at present. Currently there is about three months of back orders in house which will take time to process. Most dealers will not see any product until June. The dates are conservative estimates and were necessary to set availability expectations.
CODECS: Dolby Digital, Dolby Digital EX, Dolby Pro Logic IIx, dts, dts-ES Matrix, dts-ES Discrete, dts Neo:6 2CH, dts 96kHz/24-Bit, MCH LPCM 96kHz/24-Bit, Dual-DSP Board (Upgrade): Dolby Digital Plus, Dolby TrueHD, dts-HD High Resolution and dts-HD Master Audio. Plus other custom modes similar to those available in the current SSPs. (NO THX Post Processing)
- Optional +10 dB boost added to each MCH LPCM.
- Trim compensation features available for early DTS music recordings.
- Multiple configurations to level settings and manage bass engaged manually, by input or stream type.
All of the current sample rates including 7.1 channels at 192kHz/24-Bit are supported. However, the DAC systems perform best with the lowest THD+N when implemented as 96kHz input. Therefore, the SSP-800 will sample rate convert the signals to 96kHz before going to the DACs.
Room Correction: Manual PEQ, 5 Bands Per Channel
The MDS DAE DSP upgrade board is capable of Audyssey and Trinnov automated room equalization but support for either feature has been suppressed at present given the complexities involved in proper room correction which cannot be trivialized with the DSP alone.
DSP Board: Momentum Data Systems MDS DAE-7 (7101) Module
- Texas Instruments Aureus DA610 Chip
Dual-DSP Board (Upgrade): Momentum Data Systems MDS DAE-7D (7103) Module
- Dual Texas Instruments Aureus DA710 Chips
- FREE, Field Upgradable, Expected later this year or the next.
Each custom built OEM MDS DSP board is derived from a corresponding stock MDS DAE-6 and MDS DAE-6D DSP board. The boards were engineered to cooperate with Classe's home grown system board circuits which include but are not necessarily limited to their own implementation of power supply, volume control and DACs.
It is believed that both the current DSP and future dual-DSP boards are capable of DSD processing but it was not factored into the SSP-800's specifications. It is unknown whether a later firmware update would enable this feature or not. If significant interest was present in both the user community and in the form of HDMI enabled SACD hardware to make the investment in time and resources worthwhile it could be possible but it would be a long shot at best. The SSP-800 does not include the DSD DACs necessary for optimal performance and as such the signal would need to be converted into MPCM. All HDMI capable SACD players presently provide this facility circumventing the need to implement it within the processor.
