Esoteric Grandioso... In the House!

Gary, and Gary... thanks!

Every time I fire up my K-03, I get goosebumps. Esoteric really does set the bar for digital. I can't even comprehend what a grandioso stack must sound like. If my experience with the K-03 is anything to go by, your room must be filled with unicorns and fairies carrying every note to your ears. Congrats, my friend!

Marc... thanks; how did you know?

David... thanks; here is the whole stack in case you missed it.

As I patiently wait, and occasionally listen as the Stack breaks in, I am reading and finding out more and more about these components.

Outstanding sound quality with 36-bit processing resolution

Aiming for the pinnacle of sound quality, we have incorporated the AK4495S, a state-of-the-art 32-bit DAC device developed by Asahi Kasei Microd-evices Corporation. Sixteen circuits per channel are provided to achieve phenomenal linearity and low noise. In addition to direct processing of the DSD signal, a new 36-bit D/A processing algorithm has been adopted for analog conversion of the PCM signal at 36-bit resolution. The result is fine, smooth sound quality as along with high resolution.



ESOTERIC has developed an original, state-of-the -art transmission format called ES-LINK4, which allows DSD and 352.8kHz/48bit PCM ultrawideband digital transmission using an HDMI cable. ES-LINK4 performs a large part of the digital signal processing on the sending side, greatly reducing the digital signal processing load on the D/A converter. In addition to ultra-wide bandwidth, we sought high sound quality through our “Pure D/A” concept, in which the D/A converter specializes in its original function of D/A conversion processing.
The D1 applies a 36-bit D/A processing algorithm that converts PCM signals to analog signals at a high resolution of 36 bits by combining several 32-bit DAC devices. The tone of the high-bit data is used for faithful analog conversion. The resolution of 32-bit encoding is 256 times higher than that of 24-bit encoding, and 36-bit encoding gives an amazing resolution level that is another 16 times higher – a total of 4,096 times higher than the resolution of 24-bit encoding. Producing even finer bit tones minimizes operational error for outstanding expression of even subtle music signals.
The clock circuit, which supplies highly accurate reference clock signals to a digital circuit, can be considered the core unit of a digital player. The clock circuit of the P1 and D1 is completely independent of other circuits, including its power source and ground, enabling pure clock signals to be supplied to the system. The voltage controlled crystal oscillator (VCXO) was developed especially for the P1 and D1 in a joint effort with Nihon Dempa Kogyo (NDK), a major manufacturer of crystal oscillators. For a high-precision custom clock device worthy of leading models, high sound quality playback is provided thanks to an extremely low level of phase noise and a crystal element that is even larger than before.

I'm gonna go out on a limb here and say "I bet this does not sound any better than this..."

Just sayin..

That is one SWEET machine!

^ Those were the days.....right in the middle of a song..."CLICK!!" LOL

Absolutely amazing Ivan, congrats!

Something I find odd though on this seemly spare no expense design is why just 2 channel? Why didn't Esoteric design it for multi-channel as there are to my knowledge multi-channel DSD files out there and certainly multi channel SACD's.
