In Reply to: RE: Oppo Sonica DAC posted by RadioWonder on December 22, 2016 at 06:08:16
Oppo is not a tweak company....that is, they do not listen critically to their components. They give greater features and value and basic sound/picture quality than anything at their price point. But they do not really know how to make something sound "musical". They use not great sounding output stages, clocks, electrolytic caps, resistors, diodes, have undamped parts, etc., etc. However, most of these things can be changed and upgraded so a modded Oppo sounds nothing like a stock one. The stock Oppo sound is dry, grainy, compressed and missing lower midrange energy. Every stock Oppo sounds this way (I have heard them all except the headphone amp). When modified they can sound outrageous with way bigger soundstage, more air, more liquid, more dynamic, more warm, etc. etc....better in every way. The Sonica DAC will no doubt give the best combination of features and performance for the money but its audio sound will still be stock Oppo (well, I would like to be wrong here....we shall see).
The new ESS DACs are outrageously good. And they have 7 possible digital filter options. If Oppo does not give you the option to choose the digital filter this is really not good! Also the Oppo will only do DSD256 via usb and the really hot thing is using HQplayer in a high powered Windows 10 machine and upsampling all music to DSD512. The $900 Gustard X20U pro DAC (that also allows you to pick any of the 7 digital filters) can take DSD512 via I2S and early next year Singxer is releasing a gadget that will pass DSD512 via I2S allowing all Gustard owners to hear the glory of upsampled DSD512.

and upsampling all music to DSD512"
I take it that's not something one can easily do with the OS-X version of the HQPlayer and a MacBook Pro? Even a new one with a fast processor and a Radeon Pro graphics chip to offload some of the calculations to?
Dang! Back to Windows again. :-(
In case you weren't be sarcastic, HQPlayer works great on Mac.
If that works DSD 512) on a Mac Mini I might be tempted to try a DSD DAC.
It doesn't hurt to try but I have gone up to DSD 128 only.
I do not dislike DSD but there's hardly anything out there that is truly DSD from beginning to end. Of the DSD music that I have heard (files and SACD), my preference is hi-res PCM. 99% of my music is PCM and I'm not inclined to re-purchase it in DSD. And when I upsample / convert what I have to DSD, yes it tends to 'smooth things out' but to my ears it borders on artificial. Just my preference for hi-res PCM I suppose.
The discussion here is about DSD at high sample rates. The argument, and you are free to disagree, is that PCM converted/upsampled to high sample rate DSD before being converted to analog sounds BETTER.
Again, you are free to disagree. PSAudio, the maker of your DAC seems to think so as that's what they are doing in their DirectStream DAC as the upsample everything to 10x DSD before down-sampling back to DSD 128 for conversion to analog?
The makers of HQPlayer software seem to think that as they allow one to take PCM and convert it to high rate DSD (up to 512?) and send it to your suitable equipped DAC for conversion to analog.
Have you tried that? Does your DAC do DSD 256 or 512? My guess is not.
So we will have to wait and see, I guess.
No, I have not tried DSD 512 and I'm probably not going to. I am perfectly happy with my 24/96 PCM. Besides, I'm waiting for MQA - the new flavor of the year to be widely adopted !!
your PS Audio Nu Wave DSD Dac!
If the up sampled DSD sounds artificial to you, why not get one of those PCM R to R Dacs?
Ahendler has one, can't think of the name, he swears by it.
I recently directly compared my Mytek 192/DSD, Lampizator Euforia DSD only, and Sony Z1.
The Sony was SO much better, sounded "Right" where the others didn't, not really even close, to me.
I would be smiling when the Sony was on, frowning when the other 2 were...
My Marantz UD 7007 was (is) in the shop, so it cleared some room to do the comparison on my Den System.
Native or Upsampled, it's great, at DSD 128.
My PS Audio NuWave DSD DAC does not convert to DSD.From the Stereophile Review (and it's also on the PS Audio website):
..." the NuWave DSD and the DirectStream are very different DACs. The NuWave DSD does not convert incoming signals to DSD . It does use a dedicated DAC chip (a Sabre32 Hyperstream, from ESS Technology). And while the NuWave does employ a programmable........ Both DACs use passive filtering at the output...."
Yes, I know how much you love your Sony. I returned mine not because of it's sound but because I disliked it's constraining software and somewhat clunky (IMHO) user interface and control App on the tablet. But I've grown to expect the flexibility of a computer based system. Just me perhaps.

But HQPlayer does, which is where this part of the thread started.
But, for some reason, that does not sound good to you on your PSAudio New Wave DAC. Who knows why?
In the $2000 price range the Audio-GD Master 7 does it for me. All those Burr Brown PCM1704U-K's ladder DACing along in parallel just seem to sound right to me.
That does NOT mean that HQPlayer up-sampling those PCM files would not sound good with a new ESS9028 based DAC, especially if up-sampled to DSD 512.
Depending on how much the soon-to-be-announced Singxer SU-1 XMOS XU208 USB Digital interface capable of 512 DSD costs(current model is less that $400), it plus the new GUSTARD without USB (currently $800) might be a reasonably priced alternative.
IF I don't have to buy a new Windows 10 box to use HQPlayer at DSD 512, of course. =:-0

Yes, but I was asked about the NuWave DSD so I replied and corrected oldmkvi's misunderstanding of this DAC.

I never said it does not sound good. I said I prefer hi-res PCM 24/96 to DSD, and this has nothing to do with my PS Audio DAC as I have listened to DSD on other DACs and other systems.
This circles around to my other comment that I believe the overall DAC design and 'voicing' are more important than which new whiz bang DAC chip of the month is used. I've heard ESS Sabre based DACs that sound like crap and others that sound wonderful! Go figure.... Oh, I already did. It's not the DAC chip, it's the implementation skill in the hands of a good audio designer. ;-)
But who knows what HQPlayer upsamping PCM to DSD 512 would sound like with a suitable DAC to convert said stream to analog?
Not me.
Korg states that a 3.2 GH Processor or better is needed for on the fly conversion to DSD 2x.
Mine is 3.2, no glitches with 4x.
Headless Mac Mini with nothing else running and 16GB RAM.
Wish me luck!
I could be wrong but I think Mac OS X is suitable up to DSD 128. If I'm not mistaken what oldmkvi has is a DAC with proprietary Mac OS driver able to get his DAC beyond DSD 128. There are pluses and minuses to this approach. The plus is obvious if you want greater than DSD 128. The minus is that you're at the mercy of the DAC company to provide updated drivers as Mac OS is updated possibly not supporting older drivers. The other potential problem is attaching this DAC to a Linux based streamer. Does Exa make a Linux driver? Does the streamer manufacturer support that driver or do they allow the end-user to install the driver?The other challenge with your Mac, or any laptop w/o nVidia graphics, is that you will not be able to use CUDA GPU offload which HQPlayer supports. That doesn't mean you cannot use HQPlayer, it just means your CPU utilization will higher than that of a PC/Mac with nVidia graphics and HQPlayer GPU offload enabled. No big deal unless you do some heavy duty sample rate conversion that taxes the CPU.
Let us know if you are able to get beyond DSD 128. I'd be real curious about this as my knowledge about the above is not 100% but I have my suspicions. What DAC will you be using?
Mercman (Steve) has lots of experience with this on PC and Mac.

Which claims support for native DSD 512 via I2S via HDMI cable.Right now I know of no way to interface a laptop USB to I2S at those rates but I have plans to purchase a Singxer SU-1 XMOS XU208 box anyway as it is supposed to be a superior USB interface, much better than the AMANERO USB card currently internal to my DAC which has I2S via HDMI input anyway.
I've heard the Singxer pcb card in a small box with the new XU208 chip in another system driven by a uRendu and the owner is very happy with it.
It only goes to DSD 256 but there are indications that may change early next year.
The idea of upsampling to DSD 512 in software and streaming to a DAC capable of dealing with that would be interesting, if one could do it for less than $1500, the price of the GUSTARD DAC and the Singxer box.
Add a Windows 10 computer with a high end graphics card and suddenly I am losing interest.
Seem to recall that older MacBook Pro had a discrete nVidia graphics option?

Interesting yes, but worthwhile? I guess you'll find out if you go that route.

You don't NEED the high-end graphics but HQPlayer can be CPU intensive. In simple terms HQPlayer can shift much of the processing load to nVidia graphics cards because HQPlayer was written using the CUDA API to take advantage of certain nVidia GPU cards if present.
HQPlayer is definitely fun to play with. I found it interesting to observe HQPlayer's CPU utilization doing different sample rate conversions. Some were fairly modest while others really taxed the CPU. That was on my Mac Mini 2.6GHz i7 Quad-Core with 16GB RAM.
Oh, and if you do decide to get a Windows PC at some point, an old one may not be the bargain you think it is. Newer CPU's, even in our tiny Mac Mini's, can out perform huge PC workstations that are only a few years old.
This was a comparison I did a while back of an inmate's eBay 39-Lb. Dell T5500 workstation that he was very excited about. It is slower than my 4 year old 2.6-Lb. Mac Mini in terms of CPU performance.
Seem to recall that older MacBook Pro had a discrete nVidia graphics option?
Some did, but like many older computers they also had slower CPUs, slower memory, slower graphics cards, and overall slower internal architecture. Probably not worth the investment going that route if you want GPU performance. If you want nVidia graphics you will likely want a decent PC after all - must have x16 PCIe slot and aux power to support power hungry high-end GPUs - or get a "gaming laptop" similar to the one Mercman has, but it must have nVidia graphics to support HQPlayer GPU offload. I would not waste money on an old noisy PC that starts out being slower than your present 2.6-Lb. Mac Mini.
As an aside, you may have seen the webpage linked below from Mojo Audio. It's an interesting read on DSD, PCM, and R2R DACs.

2.6GHz Dual-Core Intel Core i5 (Turbo Boost up to 3.1GHz) w/ 16GB RAM is all I have going in my current production Mac Mini.
I doubt it would be able to deal with up-sampling PCM to DSD 512.
They are quite different devices. XMOS relies on Thyescon TUSB drivers which are customised and updated frequently. Most devices omit the essential elements in the driver ie TUSB Control Panel and TUSB Spy. The former allows for things like Latency to be varied, allowing for minimal buffers. I guess that many customisations use the safe or nearer safe setting, which doesn't to me sound as good. TUSB Spy allows for the monitoring of usb errors which can be seen in some systems. Many Chinese XMOS cards come with up to date drivers but do not contain the CPL and monitoring features. Many other XMOS implementations use 1.6x drivers whereas the latest is 3.34 . The newest drivers do sound better.
Amanero is a different beast. It has a stable driver set from 2013, aimed at accessing the KS mode. Manufacturers who use it have add ASIO drivers to some devices. Curiously they cost more from China than XMOS devices.
The two cards sound different but I would'nt say which is better. It all depends on the setup and peripherals. DSD via KS at 352.8k 24/32 bit actually sounds very good using a good filter using either hardware.
A majot reason why usb cards sound different lies in the quality of USB to I2S conversion where 44.1 x and 48 x related frequencies have to be generated by XOs. It is the qulity and implementation of these which matter.
