It accomplishes this task in a singular manner—using a dynamic yet rugged optical ROM reader, the data is read from the disc in bit-perfect condition. Instead of smoothing over any read errors as other transports do, the MSB transport reads the disc repeatedly until the file is read perfectly, much the way a computer reads a data disc. The stored musical information is then played back with perfect timing, synchronized to the DAC, with extremely low jitter using our proprietary clocking technology and the MSB PRO I2S Interface.
Unlike a traditional CD transport, you’re never listening directly to the data from the optical disc. Instead the data is pulled off the disc, stored, rebuilt and clocked back out using the highly stable clock of the DAC.
The results are remarkable. Based on comparisons with any standard technology CD or computer based system, the Signature DATA CD V produces exponentially better sound quality for any listener on any system. This transport redefines the audio listening experience, unlocking all the musical magic stored in your CD library.
The Signature DATA CD V possesses several unique features. First of all, the player uses the metal MSB Signature drive. The drive is rugged but can still be replaced easily. With this feature, the drive can be updated as technology changes, ensuring maximum versatility.
The most exciting feature of the MSB transport is the ability to read high resolution computer files without the use of a computer. Not just common resolutions, but .WAV files up to 384 kHz sampling rate and 32 bits. As a result, computer data files previously recorded on a CD or DVD can be played just as easily as standard CDs.
The Signature DATA CD is also unique in that it’s the first transport MSB has produced that includes the super low jitter ProI2S interface which transmits the DAC reference clock to the transport and transfers the data back to the DAC in perfect synchronization and isolation.
As usual with MSB products, our minimalist design eliminates unnecessary gimmicks, all the while providing revolutionary playback in an arresting and stunning package.
About Output Clocking
Our effort to get a bit-perfect read would be undone if the output timing was off by the slightest. Depending on if you’re using this transport with an MSB DAC equipped with the ProI2S input or another DAC, the data is output using an asynchronous ultra-stable clock. An asynchronous clock simply means that the master clock is completely independent from the optical disc reader.
In a standard CD player or Transport, the master clock is synchronized to the optical disc reading mechanism. As a result, you’re relying on a mechanical spinning mechanism and all of its correction systems to give you a stable, fixed clock to feed the DAC. The only problem, of course, is that it’s not at all stable—that’s where we come in.
Here’s the problem. Optical disc readers are constantly changing the rate at which the data is coming from the disc. Sometimes it comes faster and sometimes it comes slower than the fixed speed of an asynchronous clock. If that data is coming in faster than the clock, you get a traffic pileup and the system crashes. Too slow and nothing comes out.
Our smart memory storage buffer is big enough to handle any speed variation of the optical disc reader. Because it’s an intelligent buffer, the length of the memory is automatically adjusted to fit anything the optical disc reader is doing and feeds the master clock what it needs and wants. The system is really quite simple.
From here, the data is sent to the DAC. With an MSB DAC equipped with the ProI2S input, the data is moved using the reference clock in the DAC itself. With a non-MSB DAC, an ultra-stable internal clock is used to output the data for the best possible DAC performance.
About Upsampling
Upsampling is an option with this transport. Having solved the disc read and output issues, upsampling is capable of optimizing the performance of an individual DAC. Different digital filters are used for different input sample frequencies; most DACs will sound better with an equivalent higher frequency input, and for those, upsampling can be a real benefit. We don’t recommend using upsampling in the transport if you’re using it with a MSB DAC. When you use the ProI2S input, the transport knows you’re using a MSB DAC and turns the upsampling off. But for any other DAC, you’ll find the default MSB upsampling a significant improvement.
About the Drive
Over our 20+ years in the industry, we’ve been designing and building CD transports that redefine what transports are capable of. The core component to any successful transport is the drive. After exhaustive research, we settled on a drive that produces bit-perfect playback, runs quietly, possesses robust mechanics, and has unparalleled error recovery, tolerating even badly damaged CDs. We packaged the drive in a solid mechanism, adding a stunning metal drawer. The drive performs one function perfectly, reading the data from the disc impeccably. It performs better than any CD player, with a single read playing at real time. The art is threefold: the right drive must be selected, you have to know what to tell the drive, and finally, the drive has to know what to do with the data once we have it.
