T+a dac 8 dsd

[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 ;-)

[m3lraaHnevetS]

just ordered both, lol

will report in about 6 weeks when all have warmed up a bit

After talking to Amanero's designer, perhaps we are close to the finishing line for Linux support. Last night it was working at the measuring instruments. Today it will be tested with music and, if it's all OK, new firmware will be released immediately.

Keep an eye on github.

[m3lraaHnevetS]

yeah! great news bibo01

 

but how does one apply the firmware (once there)?

[kaufenpreis]

Gramophone however currently has a DAC 8 DSD that we sent them. A customer in their area was interested and we sent it to Gramophone for a demo.

There are instructions on Amanero site.

Anyhow, let's wait to appear first. We had various false alarms in the past few months.

There are instructions on Amanero site.

Afraid to say that there is no instruction specified to T+A DAC 8 DSD box on the site. Though I'm quite accustomed to the procedure necessary to update the firmware of Amanero board (I mean Combo384 board), I suppose that it will not be that easy to update the firmware implemented into T+A DAC 8.

 

Though I have never opened this DAC box of mine, I could not locate the part corresponding to the pads to make a contact for erasing the flash memory of Amanero, the procedure necessary for the firmware update, as long as based on the picture shown in the #10 message of this thread. Also, without opening the DAC box, it will not be possible to do it. Furthermore, it is not confirmed whether or not the ConfigTool.exe used for writing CPLD and firmware into Combo384 can be applicable straightforward to this DAC. Correct me if I'm wrong and there are other ways for update.

 

That said, even if this update is really of value, it's my current thought that I will wait until T+A can accept it and become willing to provide a risk-free, official firmware update.

Yea, but there is said to be a SQ discount on both outputs when used simultaneously.

 

I've just got an email from T+A that says both can be used simultaneously without compromising the sound quality.

Hmm, think I will wait too...

Good news, and yes it does work for sure. Enjoy!

Here we are!!!

Amanero's firmware update (Big Endian) should be visible to the public in a few hours. The developer will announce it on github. Keep an eye on github for possible kernel update.

The new firmware should be OK because it played back DSD256 and 512 (this one with some hi-cups due to system/algorithm).

Eventually, a slight revision to internal fifo could be arranged.

 

As mentioned before in this thread, T&A firmware update is a slightly more complicated procedure.

That's good, then I can fully use DSC1 with my Linux workstation...

 

I guess that's the cost of doing big endian format support, the USB MCU can quickly run out of steam. I still don't understand why bother instead of little endian. HQPlayer anyway supports both.

[vgrubb]

Any guess on the timeframe for T+A to ship DACs with the updated firmware?

[twluke]

Maybe to support the current 0.19 MPD? (sorry for this OT comment)

Couple of months ago they told me they had no plans to do it.

In the end Amanero has released a little endian version - 199c - it is online right now, although it's not mentioned yet on github because the developer could not find the link. However, he is just about to put online a big endian version too. They will be easily differentiated as "big" and "lit".

OK, absolutely fantastic! I will try it out today!

Fix the freaking MPD instead! Much much easier, and any way right thing to do!

 

Players should support all the formats ALSA supports. Software is supposed to adapt to the hardware, not the other way around. You have much more steam in the computer to deal with the data arrangements than in a tiny USB controller MCU. Intel CPUs have an instruction that can swap the bit order of a word with one instruction running at GHz speeds!

[bibo01]

OK, absolutely fantastic! I will try it out today!

 

Have you tried it? Is it fine, as reported, at DSD256 but not at DSD512 for you too?

[chad-ra]

Going to try this again! For some reason my posts are not going through.

 

The day this was mentioned here I immediately contacted T+A. Luckily our service rep was just there for training for 2 weeks. So now for North America we have someone in NA who can repair the DAC 8 DSD and not have to ship it back to Germany. *not that they will ever break!

 

Anyways, here is what the T+A engineers informed us of:

“We are constantly in contact with Amanero. The current Amanero firmware version which supports Linux is not stable enough for the DAC 8 DSD. They show signal disruptions, clicks, increased distortion and other problems with DSD512. When a stable version is available then we will use that for our DAC 8 DSD, but until then we have to wait.”

I am sure it's going to be a question of ironing little bumps out from the initial firmware update and then have a kernel update to support it.

My incoming preamp is single ended. My Rogue amp has transformer coupled balanced input but still single ended. According to the report, I should be using balanced output of the T+A dac.

 

Can anyone please suggest the best way to take advantage of the balanced output of the T+A dac?

 

XLR to RCA cable vs Jensen transformer vs something else?

[hifial]

This is an invitation to anyone that is interested to hear the Sound Galleries SGM 2015 music server and the T+A DAC 8 DSD. I will be showcasing them in my home system in Nutley, NJ 07110 on Dec 11th 2016.

 

This will be during the NJ Audiophile Society Holiday Party which is being held at the Clubhouse in the private community that I live in. You will be welcomed to check out both.

 

You will be asked to first stop at the Clubhouse to wait for the next available seating at my house, which is next door. Arrival time will be 4:00-6:00PM but no one will be rushed out the door.

 

Anyone who is interested PM and I will give you the info. Seating may be limited depending on the response but I will endeavor to accommodate everyone.

 

Besides the above my system consists of the following: B+W 802D; Merrill Audio Veritas Amps; Interconnect and speaker cables by Merrill Audio; High Fidelity Cables power cables and power conditioning; Anti-vibration under all equipment and speakers by Stillpoints.

 

Cheers

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 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
