In Reply to: RE: FPGA tech can turn EVERYTHING into DSD posted by oldmkvi on December 27, 2018 at 09:56:52
Only certain types of FPGA configured DSD devices take lower resolution 16/44 level and CONVERT them to DSD.
Most DSD DACs play redbook level at redbook level and DSD level at DSD level.
IMO, - nothing that says Sony on it performs well: but that's just my opinion...

I've done it on my 6 year old Mac Mini, but I've never been overly impressed with DSD or SACD.

running DSD at the source with HQ player has issues that run the process DAC does not, - or may not. HQPlayer is a solution that can be effective for some, - but not right for others......

....that FPGA based DACs are necessary for DSD conversion.
I never wrote that FPGA designed gear is necessary for DSD conversion.

for the last bit...
I love the DSD thing, both playback and some of my own Recordings on Sony D 100.
My Z1 is my most satisfying Digital Component.
FWIW, the Developer of HQ thinks Software should do DSD Conversion, not the Dac.
The Z1 is more Integrated, but not FPGA.
HQ on Mac is quite good too, tho.
...so I said it again with more detail ;-)My point is this. PCM to DSD conversion does not require an FPGA at all whether done in the audio hardware (DAC) or on a PC/Mac in software.
"FPGA" is just another popular bullet point for the manufacturer's glossy marketing slick. FPGA simply allows the manufacturer / user to "field program" the chip with updates which is nice for some folks but that doesn't mean only devices with FPGA can do DSD conversion.
I'm not envious of FPGA equipped DACs. Mine sounds just fine w/o field updates, thank you very much.

I am sure that every Directstream DAC owner will disagree with you.
And of course, - as an Audiophile, - purchaser of high end audio "marketing slick," - your hypocrisy here is notable

you posted before...
My favorite which I presently own is the PS Audio NuWave DSD DAC. It is no longer made. I put it right up there with my Ayre QB9-DSD DAC which I also owned. I ever so slightly prefer the PS Audio so I sold the Ayre. Both outstanding DACs.
Presently have:
- PS Audio NuWave DSD DAC
- Wyred4Sound DAC2-DSD
- Mytek Digital Stereo192-DSD
- Teac UD-501 USB DSD
- Wyred4Sound uDAC
- Apogee Groove USB DAC
- Allo BOSS DAC (on a Raspberry Pi)
I've probably had nearly a dozen others over the years including some costing upwards of $5000 and another that was supposed to be a $199 giant killer. It was junk.
Hmm, I guess it's time to sell off a few more DACs ;-)
of being a certified member of the 'DAC of the Month' club.
Best get busy! :-)
From Wikipedia: "A field-programmable gate array (FPGA) is an integrated circuit (IC) that can be programmed in the field after manufacture. FPGAs are similar in principle to, but have vastly wider potential application than, programmable read-only memory (PROM) chips."
In other words, an FPGA can be programmed to do any task that the programmer assigns it. Most are not even used for audio. ;-)
Indeed, - most Field Programmable Gate Array chips are not used for audio.....
These DACs that use FPGA tech are the "process" behind up-converting everything received to DSD..
