The Jason transport is built to the same exacting standards which make our studio equipment a first choice for many professionals. With studio sound quality to match the unbeatable build quality what more could you ask of a top flight transport.

Chances are high that a substantial part of your CD collection has been mastered through Weiss equipment. A good reason to go with us for your High-End Hi-Fi requirements. Bob Katz, is one of our pro audio customers and one of the best-known and most highly regarded mastering engineers in the USA.  

Upsampling
The JASON contains an upsampler feature which allows to upsample the basic 44.1kHz / 16Bit data stream from the CD to 88.2 kHz or 176.4 kHz for subsequent D/A conversion. For the upsampling we use our proven algorithms used by many of our professional studio customers.

Wordlength Reduction
The upsampling process has the effect of generating a wordlength longer than 16 Bits, in the JASON a 40 Bit Floating Point format is generated. In order to output the upsampled signal, it is reduced in its wordlength to fit the standard AES/EBU or S/PDIF formats. This wordlength reduction uses the POW-R # 3 algorithm, which is one of the best wordlength reduction schemes, widely used in Pro Audio equipment. The output wordlength can be selected between 16, 20 and 24 Bits, which allows to hook up a wide variety of D/A converters to the JASON.

D/A Converter Enhancement
The JASON uses a specific method (spread spectrum technology) to treat the output signal such that the clocking quality of the subsequent D/A Converter does not have much influence on the audio quality. This allows for the use D/A Converters with non-ideal clocking performance.

Weiss Medea D/A Converter"Whoa! That was my first reaction to the Medea. Oh my was my second. I wonder if can afford to buy this thing? That was my third. I’ve never heard a digital processor resolve as much information as this one does. The Medea unveils loads of detail -- through the high, mid, and bass regions -- to the point where I was scrambling for disc after disc to determine if what I was hearing was some sort of illusion. It wasn’t. " - SoundStage	Zanden 2000P CD Transport Previously, if someone had offered to replace my record players and record collection wholesale with CDs and a player of my choice, I'd have questioned their sanity and then shown them the door. Now I'd have to consider that offer seriously. That's how big a step the Zanden digital electronics represent. - HiFi +
Boulder 2020 Digital to Analog Converter This attention to analog performance is simply unprecedented. Total crystal re-clocking completely eliminated jitter, and an eight times oversampling FIR digital filter produces superb transient response. Five Burr-Brown DACs in parallel per channel significantly lower distortion and increase accuracy to theoretical limits. Boulder's unique three-chassis design affords maximum isolation between digital and analog circuitry. The separate power supply chassis houses independent regulated supplies for each channel, as well as the digital / display chassis.	Zanden 5000S Digital to Analog Converter Have you ever heard a standard CD sound better than a top flite SACD player, if the answer is yes they I guess you have already heard the Zanden. Am I exaggerating, not in the slightest, it is more musical, more harmonically rich and musically correct, it does not fall foul of the SACD convertor sound (yes it has one) and there are millions more albums available and they are cheaper. For a moment I thought I was listening to Vinyl, yes its that good!
