"Just saw this posted on HQPlayer, a direct comparison of the software against the Chord Hugo M Scaler on Chord TT2 and DAVE DACs. I repeat what I wrote last May in another post when David McGown wrote: With this config, the cost of HQP goes in the 5k-6k range, lot more than a new MScaler. If you wish to upscale redbook to DSD512 using Sinc-L filter, quality GPU like Nvidia RTX 3090 is necessary which costs about $3,000. Fiberoptic network rejects all noise in the electrical network. Convert the electrical network into fiberoptic network. Use of dedicated add-on NICs from companies like JCATī. There are 2 ways the network noise can be eliminated.Ī.
HQPLAYER COST FULL
To realize the full potential of these cards, they need to be powered by dedicated external LPS like SBooster, Shanti etc.Īvoid wireless networking at any cost in the HQP server.Įven in the wired network, there is lot of noise in the data lines. These cards have quality clocks and noise filtration circuits. It is noisy and jittery.Ī quality PCI USB card from companies like JCAT or SOtM are absolute necessity. The default USB interface which comes with any motherboard is not suitable for high end audio. In addition to what Roscoe posted about HQPlayer server, following upgrades are necessary for quality audio IMO. Decimating down to 705 kHz has no SQ problems so long as you eliminate aliasing, and you do that by having 220dB filtering. But these filters sound noticeably inferior to the filter in the M scaler (and TT2, it's identical code), and this is due to the Dave DSD+ filters not being as effective as the M scaler filter. In Dave I have DSD filters that are non-decimating - they just filter the incoming bitstream and maintain the sample rate. So you may question why decimate down to 705kHz and not maintain the original DSD frequency. In this case simple is not the best, it's just distorted. So why do we need to process DSD? Two reasons - one to do volume and cross-feed functions (which need n bit PCM - remember too that DSD is PCM it's just 1 bit), and second is if I didn't remove DSD's distortion and noise I would get poor analogue performance, with noise floor modulation and copious levels of distortion. This filter is extremely effective, with 220 dB attenuation of out of band noise. So the DSD treatment isn't quite as stated - it's via a dedicated filter that takes the DSD, removes the hideous RF noise and out of band distortion and noise from DSD, and decimates it down to 705 kHz.
