T+a dac 8 dsd

[louisxiawei]

Thank you so much for the reply.

 

by using HQplayer, my friend and me cannot smoothly upsample the T+A to DSD 512. There is some pop sound appearing from time to time. Poly-sinc-2s doesn't help, buffer time remedies it but doesn't eliminate the pops. CPU takes up 50% + in that case.

 

With my friend i5 6500 CPU, the pop disappear and the smooth DSD sound comes only from the DSD256. CPU takes up to 25% in DSD256 case.

 

One funny thing is my friend then used foobar to upsample T+A to 512 successfully without pop sound. But I doubt the CPU might not be taken advantage of properly because I also trust HQplayer more in terms of upsampling. (Hope someone might help me out regarding this)

 

Me myself, am using Exasound e12 with HQplayer upsampling to DSD256. Fantastic!

 

But haven't compared them AB yet, anyone got idea Exasound DSD 256 vs T+A DSD 512?

 

 

 

 

I don't think you can do DSD512 over DOP. You really should be doing ASIO for the higher DSD sample rates.

You may be able to do some DSD512 upsampling with an I5 just fine if you stick to the poly*-2s filters, but YMMV. Ideally, to get the most out of all the filters, an I7 is recommended.

Don't know about Foobar....I'm an HQPlayer fan all the way

Hello guys,

 

Just want to ask a few questions here regarding T+A DSD upsampling:

 

 

• does T+A need a powerful cpu like I7 to do DSD 512 upsampling? I see some of users have difficulty upsampling to DSD 512 with I5 cpu. Can someone share some HQplayer setting for T+A DAC8 DSD?
  
• Does T+A support DOP? My friend is now having difficulty upsample his T+A to DSD512 by ticking the DOP option doesn't help and his CPU is I5 6500.
  
• last but not the least, what's the SQ difference between HQplayer upsampling and Foobar upsampling to DSD 512?
  

 

Sorry to be a pain asking so much and any help would be appreciated.

 

 

I will chime in but I hop so will others.

 

1) Yes, you need a powerful cpu like a Skylake i7 6700K to do upsampling to DSD512. It is not that the T+A needs it but HQ Player does in order to have the power needed to do the very intense processing.

 

2) As far as I am aware you can not do DSD512 in DOP. It is my understanding it does not have the headroom in the rapper. T+A needs a driver to do DSD512 (and DSD256) and you can get it on their web page. It is only for Windows. NO Mac for DSD512.

 

3) There is a HUGE difference, IMHO, between HQP and Foobar when upsampling to DSD512. Not that Foobar is bad sounding mind you.

Thanks for the reply, hifial.

 

Sorry to copy paste the message again to you, since you might be the correct person to ask. (You have experience in both exasound DAC and T+A)

Well the computational power that HQP needs for its algorithms to do the upsampling is much more intensive then what Foobar needs. So that is why one is able to do DSD512 with foobar with just an i5.

 

It is like asking a Formula One race car to run on ordinary gasoline and ask why it is braking down and under performing.

 

After hearing the T+A do DSD512 I sold my beloved exasound and bought my T+A DAC. And I do not make a big change lightly.

[louisxiawei]

Well said and what a good metaphor for me to better understand

 

Much appreciated for the reply. Guess I need to prepare to sell my exasound sometime as well.

My personal audition experience from some HIFI shop and my friend's experience agrees that T+A DSD 512's sound can compete Chord DAVE PCM's one.

 

However, I do wish T+A release a DAC only has DSD circuit part, it will make it more compact and slim yet powerful.

 

Thanks again.

Can the DAC 8 DSD process DSD via DoP or only native DSD?

[juanitox]

after few month with the Dac8 i have found that DSD256 sounds good too as it needs less processing . not every records needs the small gap of the DSD512 ..

[m3lraaHnevetS]

PC is basically a case that looks like a CD player containing:

6700K on a Z170 board

Corsair RM550X Zero RPM 80plus Gold PSU

16GB RAM @ 2133

WD 250GB SSD

Scythe Low Profile 58mm 15-22dB fan

 

But build by a DAW specialist so I am hopeful it will be a quality build

 

Guess I will end up buying both Intona and Regen, compare them and sell the lesser god. or maybe keep both if they play nice together ;-)

 

so yeah, I received my HTPC, Regen and Intona industrial and can report the following:

HTPC is to noisy to keep in the music room so had to move it to the cellar and use a simple quiet win 10 PC as NAA.

Connecting both Regen and Intona at the same time gives me the best result so I keep them both.

I use the Sonore Signature Power Supply to power the Regen and this gives a much better result than Meanwell or iFI.

Converting everything to DSD512 using poly-sinc-mp and DSD5v2 256+fs is where i settled at for now and it sounds wonderful.

Especially bass is better than ever, BIG but sweet and soft at the same time.

 

Happy days

 

one more thing: my T+A DAC 8 DSD does not mute both channels 100% so using it as a pre was not a big succes. sound familiar?

I called T+A and they told me to sent it to them so they can look at it. I asked if they are planning a firmware update hoping to send the DAC in once and get both the pre fixed and firmware updated. they say they are looking at the new Amanero code and will update the firmware if they test it successfully.

I have a T+A DAC 8 DSD direct into Cyrus x200 Signature mono amps - is silent when muted / no music playing.

It does sound like your may have a problem - wise to get them to look at it.

Has anyone tried Nimitra as NAA?

I have tried different DSD's as well. For me, if you can't upsamle to DSD512, get another DAC.

I'm guessing since this is the T+A thread it's the DAC 8 DSD

From the context of this thread they are referring to using a PC running HQPlayer to upsample to DSD512, which is then fed into the T+A DAC 8 DSD for conversion. That is supposed to be the way to optimize the performance of this DAC. Many PCs don't have the required speed/processing power to perform that level of upsampling with HQPlayer.

Agree but since lotriwer noted to try another Dac so I was wondering what Dac he was talking about since few Dacs can do 512.

[twluke]

Ignore this. The iPod app for CA occasionally causes this kind of unintended posting.

[bmoura]

few Dacs can do 512.

There are some DSD 512 DACs out there. At the entry level price range, try the iFi iDSD Micro and the new iDSD Micro BL.

There are several EMM DACs, Lampizator DACs and the new HoloSpring DAC that do DSD512 or DSD1024 as well. I haven't heard any of these.

 

I am very pleased with the microIDSD DACs which sound beautiful playing from internal battery at DSD512 with SQ that continues to improve as upstream components and software are upgraded..

Sorry for the late reply. What I meant was that this DAC works it's best when fed with DSD512. I upsample everything via HQPlayer.

Exactly. Even more with DSD512 and DSD1024 shown on the NativeDSD Database.

Sound Improvements

 

Like to share some tricks with you to optimize the sound quality of the Dac8Dsd even further.

 

The Dac is very sensitive regarding power cables. Be shure to try different brands. I use Wireworld power cables with great results.

 

Dimming the "Lightshow" down to Zero opens up the sound.

 

Plug in an 75Ohm Rca into the Spdif Output (small improvement).

 

Get good footers to place the dac upon. Try small Cardas myrtle wood blocks. Incredible improvement.

 

And we all know, DSD512 is the way to go for best of the best sound.

 

Have fun!

Are you using any sort of power conditioning to plug the mains cable into?

 

What do you mean by a 75 ohm RCA?
