Thanks Antonio, this comment got me pondering a bit about myself; what is it with the obsession about DAC's, why do I have more of them than is necessary and why do they so dominate my attention?
The DAC is, for me, the 'heart' of a digital-based audio setup. It is the interface between the bitstream of zero's & one's and the pulsing soundwave that comes to your ears. The character of the DAC is what you hear from the speakers - how it deals with binary code to create music. The art is ensuring that the DAC receives the best-defined and synchronised digital information you can give it and then the output needs to get to the speakers in a way that least distorts it.
As someone who grew up with LP's and turntables, the classic 'analogue' sound is still my mental benchmark, I want my system to be as lifelike and vital as a vinyl source - but then with the ease and purity of computer tech. So my individual quest for Hifi nirvana focusses on the aspect of getting a chip-generated signal to create 'living' music .
It isn't about measurements or bit-perfect accuracy for me - I just want the music to touch my soul.
On that note, here is the order confirmation email I got from Vinshine - talk about quality control:
We would like take this opportunity to share with you some of the manufacturing processes the product went through prior shipping to you.
• Each assembled PCB will go through a first round of QAQC test includes visual check, power on to measure its parameters (THD%, SN Ratio, Frequency Response, etc).
• At this point in time, the bad PCB will be rejected, and the good PCB will proceed to assembly into the chassis, along with the power transformer, connectors.
• Burn in of 100hrs starts.
• Prior shipment, a comprehensive QAQC test with Audio Precision APX525 will be performed to ensure the measurements meet the requirements.
• On top of the measurement test, listening test of all supported sampling rate of PCM44.1-PCM1536, DSD64-DSD1024 will be performed via all input interfaces (USB/SPDIF/I2S/etc).
• Final visual check of the assembly and chassis will be done prior packing. As part of the continuous improvement, we have implemented serial number for each unit shipped.
• The package will be handed to the courier agent for shipping to the rest of the world. We ship via world-best courier services like DHL/FedEx/UPS with tracking.
• The tracking number will be provided once the order is shipped.
Our products are covered by 36 months warranty.
