Miska,

Which DAC's chipset are USB capable (not IS port) up to DSD1024 and PCM 1.536kHz?

And about your experience with ladder R2R DAC's?

Did you test some brands that can recommend to us?

Thx

Holo Spring 2 and May DACs for sure and I think Dennefrips Terminator but check that one to be sure.

T+A can also do DSD1024 over USB. For example the HA 200 I'm using.

 

What are you thinking about T+A HA 200? Does it sound much better than DAC8?

Did you try NOS mode with files converted by HQP Pro to DSD1024 with Sinc-L and AMSDM7EC?

I'm considering the T+A HA 200 as my next step, maybe the last one, so please tell us your impressions...

nice car the t + a HA200 .... but it also makes the pcm 1.536 mhz?

Jussi,
hqplayer is able to do upsamplings up to the frequency of 98.304 mhz in SDM (to simplify let's say dsd 2048)
why don't you also develop the possibility of upsampling in PCM up to 3072 mhz? .....
is that possible?
it seems to me that the only dac that does this internally is the MSB ... if there are others I don't know them.

Its specifications say no, only to 32 Bit/768 kHz!

pity it would have been great

I have not compared directly that way, since DAC8 DSD is on my loudspeaker system while HA 200 is on my office desk for headphones.

I only ever use the discrete DSD side... Not with sinc-L, but with ext2. Compared to ASDM7EC at DSD256, DSD1024 sounds a bit more "real" or "analog". And then switching to AMSDM7EC the sound "opens" or "widens" up a little. Not huge differences.

The small box on top, rear right is my NAA, so I can send audio from either Linux or Windows desktop, or my iMac to the HA 200.

 

Most of the time I run it at DSD256 with ASDM7EC modulator, because it is fine for me that way and much easier.

I believe the PCM side is same as DAC8 DSD, so 4x TI PCM1795. DSD side is discrete, further developed from DAC8 DSD.

 

The SD(V) 3100 HV is more fancy version.

Are you using it with Solitaire?

 

Yes, nice thing is that I can easily have all my three primary headphones connected to it simultaneously and then easily switch between the headphones. (Solitaire, Sennheiser HD800 and Shure SRH1540.

On Linux and macOS you can already do it if you manually adjust the configuration file. But it goes to same category as DSD2048 that there are no DACs that would have such input possibility on the market right now.

Any opinions on IFI Pro DSD dac that also does DSD 1024?

I think it does its own Upsampling with a DSD Direct type setting,

 Tubes, and Gibbs Filter.

I've read both good , and what I interpreted as Luke-Warm reviews.

I think Miska doesn't want the Dac to do the Conversions.

But I could get TV, Internet Radio and my Files , all at DSD 1024 with it.

It's at least $2500, maybe more by now, so not relatively cheap like the RMI.

TIA!

It's not about getting some rate like DSD1024, but how that rate is achieved. Good algorithm at DSD256 is better than bad algorithm at DSD1024.

TI PCM1795 is Burr-Brown?

I own a Sennheiser HD800S. so how they match with HA200 balanced output?

BTW, only by sound quality side, do you think HA-200 deserves US$9,000.00?

Yes, TI purchased Burr-Brown long time ago.

Probably pretty nicely, I'm still missing a balanced cable for my HD800, so I have not tried that way yet. Need to get a new cable first. Never bothered for the Schiit Jotunheim.

That's a question everybody needs to answer on their own. :) But it is a high resolution tool for me. And has quite a lot of features for serious headphone listening. ADI-2 Pro in the picture is also connected to the HA 200 using balanced cables.

 

Some of the features like adjustable output impedance is useful for some headphones like some Beyerdynamic models.

Still drop outs with ASDME7.Does not matter with what filter is used .This is with latest 4.71

 

Same here. As with 4.7.0, an unfortunate overload on two cores.

Did you know that Miska is in reality an agent for the PC industry? The PC industry wants to sell its newest hardware. 😂 (A joke)

I'm just eager to utilize what ever they can offer, for improved sound quality... :D

 

Too bad they are so slow rolling out faster CPUs. ;)

There are no changes in 4.7.1 that should have big impact on these things. I changed a few optimizations, but those affect Pro more (to be released some time later).

 

For me, things run the same as before on i7-8086K, i9-9900K(S) and i9-10900K. I have one new machine with the new i9-10850K which is very close to i9-10900K, but cheaper. Will test on that one later (it runs Win 10).

Miska, you have to ask yourself how many if your customers have the latest & greatest CPU’s. I appreciate what you trying to achieve, but maybe it’s just too early.

I can run DSD256 upsampling on a quad-core Atom CPU. The Intel Joule module was smallest thing that could run HQPlayer Embedded and upsample to DSD256. So it is not so demanding. Rest is about choosing the algorithms you want to run. There are lighter and heavier ones. Even the lighter ones beat typical hardware implementations.

 

I don't think it makes sense for me to limit my most advanced algorithms to the ones that can run on the least powerful computers. If someone has the latest and greatest computer hardware, I don't see reason not to offer best possible algorithms. And even with the latest and greatest computer hardware we are still talking about cheaper device than most high-end or even HiFi equipment is. I think the i9-10850K machine I assembled last weekend was a little over 1000 EUR. And it is with relatively expensive motherboard (Gigabyte Z490 AORUS PRO AX), good PSU (Seasonic Focus PX-850) and fast RAM (4 DIMMS of Kingston HyperX Fury DDR4 3200 CL16). And that PSU has enough oomph that you can later add Nvidia RTX 3080 for a lot of bang for the buck. It was a build for my friend, I will later try HQPlayer on it. But I'm pretty sure ASDM7EC works to DSD256 with it. For him, it will be vehicle to run the new Microsoft Flight Simulator when the 3080 GPU becomes available.

I get it but I am not willing to keep chasing DSD to higher and higher levels. I spent $2K two years ago on my HQP PC and I am not going to upgrade for some time to come. I have decided to go back to PCM 768 which sounds really great on my Holo Spring 2 KTE. With 4.7 &4.7.1, I can no longer get ASDM7EC/DSD 256 (128 is the max now). PCM 768 sounds better to me than ASDM7EC/DSD128. I realized that at some point one has to stop chasing the latest and greatest with bigger and bigger numbers and just be happy listening to the music.

 

What kind of machine is it? All my machines that did ASDM7EC before are still doing the same. With optimal BIOS settings and stock Windows 10, Linux and macOS.
