While HQPlayer has a chinese menu of such algorithms, they say that they have picked one and optimized/implemented that. closer to ideal response) using parallel arrays of DSP inside the FPGA. In a nutshell, he implements all upsampling and noise shaping using very long filters (i.e. So the long and the short is don't let the source mess with the signal (except perhaps with a good EQ program) and let Mojo (or DAVE) deal with the original data, as Mojo (or DAVE) is way more capable"ĭoes any one understand the technical rationale behind what he is saying?Ĭlick to expand.I read through their technical paper and it is quite an impressive design. The WTA filter is the only algorithm that has been designed to reduce timing of transients errors, and the only one that has been optimised by thousands of listening tests. That is incredibly powerful processing power way more powerful than a PC.īut its not just about raw processing power but the algorithm for the filter. Dave has 166 DSP cores with each core being able to do one FIR tap in one clock cycle. With hardware and FPGA's you do not need to do that, you can do thousands of operations in parallel.

Computers are poor devices to use for manipulating data in real time as they are concurrent serial devices - everything has to go through one to 8 processors in sequence. Do NOT use your computer to up-sample or change the data when you use one of my DAC's.Īll competent DAC's up-sample and filter internally the issue is how well that filtering is done, in terms of how well the timing of transients is reconstructed from the original analogue. Here's a quote I found from a guy named Watts, who designed the Chord DAVE dac, which competes with any DAC in the market today, regardless of price tag. Hardware, OS, OS optimization and CPU speed all make a very audible difference

The computing platform you are running HQ Player on also makes a big difference, whether its a laptop, Mac Mini with LPS, or a SGM. Wyred 4 Sound DAC 2 SE with ESS Sabre 9038 DSD 512Įntry level DSD 512, Holospring, Ifi, and LKS benefit enormously from PCM to DSD conversion using HQ Player. Playback Design MP-3 and MP-5 DSD 128 and 256
The list of DAC’s with which we have tested and found that HQ Player significantly improves the sound of Redbook by either upsampling to a higher PCM rate or format conversion for DSD DAC’s has grown considerably since the introduction of Closed From filter and the XTR family of filters over the past year
