Now you mention it I vaguely remember reading that. Good to know there are no recognition problems when cutting the vbus power.
I'll proceed as I posted above, after testing it fully in standard guise to be sure all is functioning well (KISS for first use!)

Hi Chris It's probably best to take a spare cheap USB lead, cut off the PC end's plug and replace it with a cheap solder type plug without Vbus connected, then heat shrink the new plug. That's assuming you can readily obtain these plugs. In my case they are a stocked item at all Jaycar stores. Regards Alex

Hi Guys, My solderig skills are very basic and my knowledge of the technical terms you guys are throwing about between you is non-existant (I had do do a Google' to find out what KISS meant ) but I do have an Amanero board. Is there anything I can do to progress my build at this stage or would I be better just sitting back and letting you lot work your way through the various 'problems'? My intention is to ask 'my builder' to do the difficult stuff but I just wondered if there was anything simple I could be doing. TIA, Dave.

Yesterday I flashed the new firmware to my board. Piece of cake as long as you follow VERY CLOSELY the instructions (I suggest reading them 3 times to make sure every step is fully understood before proceeding). The update log was: 1) Fixed noise in DSD output mode 2) Added I2C commands functionality ( ) 3) Improvements to feedback ( ) The whole process should take less than 2min.

Chong, other than you succesfuly updated the firmware I haven't understood any of your posts. BTW, I found out Foobar cannot do true DSD (DoP) over WASAPI or KS. The workaround is to use ASIOP4ALL as a proxy. As you don't have any DSD capable DAC yet this is no biggie and by the time you have one most probably Domenico should have released the promised ASIO drivers. HQPlayer and JRiver can output DoP over WASAPI and KS and have been verified to work with the Amanero board (pin7 - DSDOE- outputs 3.3V when DSD is present).

As you don't have any DSD capable DAC yet this is no biggie and by the time you have one most probably Domenico should have released the promised ASIO drivers. Btw, just to be accurate, ASIO is only meant for soundcards that can use it? Also, assuming all can output true DSD, between ASIO, ASIO4ALL, WASAPI and KS, which will be the ideal for DSD? HQPlayer and JRiver can output DoP over WASAPI and KS and have been verified to work with the Amanero board (pin7 - DSDOE- outputs 3.3V when DSD is present). Ah, then use JRiver. Anyway, I prefer JRiver over Foobar for subjective sound as written to you on this matter. Btw, between HQPLayer and JRiver, which you prefer for subjective sound and objective usage. Thanks.

ASIO is software related not hardware. It is the drivers of the sound card what need to be ASIO compatible. Any manufacturer can develop ASIO compatible drivers should they wish to and, in fact, most pro hardware comes with ASIO drivers. The reason for this is not better "subjective" SQ but lower latency needed for recording and monitoring simultaneously. Out of all possible paths for DSD, I'd prefer native DSD over ASIO first because it has the lowest latency and provides less processing overhead, the problem is there are very few devices with drivers that work this way. Next best would be DoP (DSD over PCM) running on ASIO and then the rest. The problem with Foobar is that in order to send DoP to a soundcard you either have an ASIO compliant driver and use the proxy provided with SACD plugin (foo_dsd_asio) or else you'll need to use a second proxy (ASIO4ALL) that receives the output from the first and convert it to Kernel Streaming (ASIO4ALL as I've said many times is not true ASIO). Unlike JRiver which has a direct path (aka bitstreaming) that skips all internal processing, the Foobar process chain is: decoder->internal DSP module->volume control-> outputin order to implement DoP without proxies it should be changed to: decoder-> outputThus eliminating the DSP module and volume control, this would allow to configure a truly transparent connection between the decoder and the output plugin which will eliminate the need for proxies. I've posted a request for this feature in HA forums but I don't have too much hope they actually listen and implement it. Btw, between HQPLayer and JRiver, which you prefer for subjective sound and objective usage. Subjective is not my field Chong, to my ears all players sound the same when configured the same and in the same system. On the other hand, the differences are obvious in the interface, functionality and ease of use departments. I'm not keen on HQPlayer, it has some serious power when it comes to options for processing signals but is quite a PIA to use they way I like, ditto for most other "audiophile" players like JPlay,cPlay, etc.

The reason for this is not better "subjective" SQ but lower latency needed for recording and monitoring simultaneously. Ok, ASIO, WASAPI, DS, etc are just proxies or software interfaces to output the needed. Btw, if latency is so important to Pro Audio, since obviously they need the shortest possible time to process thru their contents, why didn't they do away the proxies in the first place as that will be the lowest latency and best sound quality for their clients. So out of curiousity, can I say these proxies are implemented is not so much for lowest latency but easiest and lowest cost to do the thing they need? Also, we always see latency coming up in computer and carry forth to computer A/V. Do we need to have the fastest for A/V in all places, Pro and Home? As long as whatever latency works, sounds and looks good, it already have achieved its objective. Out of all possible paths for DSD, I'd prefer native DSD over ASIO first because it has the lowest latency and provides less processing overhead, the problem is there are very few devices with drivers that work this way. Next best would be DoP (DSD over PCM) running on ASIO and then the rest. That will be the best already by going native. However, in life things as usual are not so simple. We are having DSP nowadays in high end DACs as that will remove some of the irregularities in the original signal that make these Dacs sound better. Also, it depends which is making things worst. For example, upsampling is implemented not so much for the extra details thru artificial interpolation of details but for reducing phase shifts and high frequency harsh by too steep a filter used and too low a sampling frequency nearer to the threshold of hearing. So we have to weight which is the worst evil of the two for better sound. For the upsampling, the degradation thru extra processing or the better technicality thru reduce phase shifts, high frequecny sampling too near to the threshold of hearing and obviously extra detaisl created thru artificial interpolation according to an algorithm that the designer feel should be closer to the original. The problem with Foobar is that in order to send DoP to a soundcard you either have an ASIO compliant driver and use the proxy provided with SACD plugin (foo_dsd_asio) or else you'll need to use a second proxy (ASIO4ALL) that receives the output from the first and convert it to Kernel Streaming (ASIO4ALL as I've said many times is not true ASIO).

I've posted a request for this feature in HA forums but I don't have too much hope they actually listen and implement it. Thanks for the explanation. I don't think I'm looking out for DoP convertion since I hopelfully can get the DSD1792 to sing with native DSD. Yes, I do understand there are those using soundcards with just PCM inputs. Not for me. I Dac only that can do hirez PCM and DSD like the Mytek. Yeah, greedily eyeing hirez multichannel too. On the other hand, the differences are obvious in the interface, functionality and ease of use departments. I'm not keen on HQPlayer, it has some serious power when it comes to options for processing signals but is quite a PIA to use they way I like, ditto for most other "audiophile" players like JPlay,cPlay, etc. Me too as we must have a GUI that is easy to use too. Always audiophile and PITA to use is not for me. Must have a marriage and balance of both worlds to be truly great.

Ok, ASIO, WASAPI, DS, etc are just proxies or software interfaces to output the needed. Nope, I'm afraid you didn't get it right. ASIO, WASAPI, KS and DS are not proxies, they are output methods to get the signal to the sound card drivers. foo_dsd_asio is a proxy. It was developped to help connect the output of the foo_sacd_plugin straight to the ASIO output plugin bypassing the DSP module and volume control. It is the only possible way to send DSD to ASIO in Foobar. As there is no equivalent for WASAPI or KS it is not possible to use those output methods for DSD. Btw, if latency is so important to Pro Audio, since obviously they need the shortest possible time to process thru their contents, why didn't they do away the proxies in the first place as that will be the lowest latency and best sound quality for their clients. So out of curiousity, can I say these proxies are implemented is not so much for lowest latency but easiest and lowest cost to do the thing they need? Read the previous answer. Also, we always see latency coming up in computer and carry forth to computer A/V. Do we need to have the fastest for A/V in all places, Pro and Home? As long as whatever latency works, sounds and looks good, it already have achieved its objective. Sorry, I don't understand what you are trying to say That will be the best already by going native.

For the upsampling, the degradation thru extra processing or the better technicality thru reduce phase shifts, high frequecny sampling too near to the threshold of hearing and obviously extra detaisl created thru artificial interpolation according to an algorithm that the designer feel should be closer to the original. Same as previous one, me no comprende the relation of this paragraph to the topic. Thanks for the explanation. I don't think I'm looking out for DoP convertion since I hopelfully can get the DSD1792 to sing with native DSD. Yes, I do understand there are those using soundcards with just PCM inputs. Not for me. I Dac only that can do hirez PCM and DSD like the Mytek. Yeah, greedily eyeing hirez multichannel too. How do you intend to get native DSD to the DSD1792? The DSD output of the Amanero board is indeed native/true DSD but as input, the Amanero board only accepts DoP ATM. No idea whether its inminent ASIO drivers will include "DSD over ASIO" but wouldn't hold my breath on it as it is a very undocumented path that most will rather skip. DoP is a much clerar and solid standard That provides excelent results in getting DSD from the player to the USB receiver to the board processor. From there the DSD stream is recovered from within its PCM "container" and sent to the DAC. There is a very good description of what is DoP and how it works over here: dsd-guide.com/usb-link-dsd-audio-pcm-frames-andreas-kochMe too as we must have a GUI that is easy to use too. Always audiophile and PITA to use is not for me. Must have a marriage and balance of both worlds to be truly great. Amen

The second group buy is up and away on the DIYaudio site and I have paid for my board so it should be on its way shortly. I am planning to hook it up to my original TP Buffalo (Sabre ES9008 24 bit) to provide a USB interface to my DAC. Any subjective listening impressions of this board and how it might compare with other USB interfaces?

New V. 1.0.5 drivers available at Amanero's site though still not ASIO compliant.
Also new firmware flashing/I2C tool V. 1.0.6 avaliable (original was 1.0.4), latest firmware is 1.0.5 RevC3

I've finally come around to connecting the Amanero ( yes, latest driver ) Standard USB power for first test and ASYNC connection to the PK. I also have my first taste of Kernal Streaming Guts everywhere; I have to say the SQ, by memory, is already better than the super PSU'd ebay jobby, so that hope is already fulfilled. If it reacts well to the same treatment we'll be on fire. Just need those ASIO drivers now....

The page with the tool and the instructions is here: www.amanero.com/howto.htmBut the noise only happened when actually playing DSD to a DSD DAC and that is not the case with the PK. What kind noise are you getting?

The noise is a higher pitched buzz, like the noise you get from a fan when it intrudes electrically.
I must point out that the connections were all plugged rather than soldered, and all was open to any interference that was around.
I was just flicking through all the various file types and first noticed the noise on DVD-A but it's also there on SACD.
This is running off the laptop which is on its mains adapter. So after your comment I'm thinking noise from the lappy/mains or interference as said above.

I got no noise whatsoever on mine and I tested it as exposed to RF/EMI as yours. Maybe noise from the laptop is getting through. I had the same problem this summer with my laptop both plugged and running on battery and the Musiland 02 USB DAC, and the Musiland is in a proper case. I'd suggest you try it with the Atom (or any other non latptop) and see if it happens too.
