This one is quite funny. A spam post that contained a goofy link wrapped into a relevant topic about MQA. I decided to leave the post here (with the link removed), because MQA actually is a quite interesting topic. Interestingly enough, we have been in touch with the MQA people and working on the MQA implementation on the FPGA platform. We are not quite there yet, but hopefully soon enough we shoby AP - Digital Audio Technology
Hi there, Finally I had some time to play around with the filters again and export the plots. The order of the filters below is #1,#2,#3 and #4. As described in the manual, #1 and #2 are sharp and slow filter for 88.2kHz sampling frequency, #3 and #4 are sharp and slow for 176.4kHz. #1 #2 #3 #4 Please feel free to ask further questions.

Hi Dave, We have one of the prototype boards with a guy from this forum and he will trial the I2S link between the Vanity203 and his DACs for us and everyone else. In theory the I2S should give a better sound for dozen of reasons, let's see how the trial goes. If you look into the User manual (another thread), you will see that the I2S output is provided on an on-board connector with 3V3by AP - Vanity203HD (discontinued)
Hi all, We have finished the user manual, which now includes everything related to the board. It covers installation, settings, AES mod, and description of all features. If you still don't know what features the new board has, have a look into the manual! Any feedback is more than welcome. You may notice that now the manual is now JVB branded. The board will be selling exclusively via JVB,by AP - Vanity203HD (discontinued)
Hi all, Everyone who contributed with feature suggestions, here is a small thank you: Vanity203HD Introductory Discount. The offer might get extended, but don't hesitate. Regards, Pavelby AP - Vanity203HD (discontinued)
Hi David, Do you need BDP-103D (Darbee) or would standard BDP-103 be ok? We might have one spare 103 for sale (with or without Vanity103). Please let us know. Regards, Pavelby AP - Vanity103HD & Lite (discontinued)
Thank you everyone for your help and offers for testing the Vanity 203HD board. We already have picked someone to carry out the in-field testing. Regards, Pavelby AP - Vanity203HD (discontinued)

Hi guys, I guess I owe you some update. We are about to sign off the VanityHD203 board - hardware as well as software. There are a few new features: - On-board I2S header. 8 channel I2S with the same data coming from the main (SPDIF) outputs. There is a dedicated masterclock signal as well. Physically it is a 14 pin IDC header (see the photo above). The I2S output can be enabled/disabled via DIby AP - Vanity203HD (discontinued)

That it a very interesting observation. Most people find the multichannel mix a bit plain and disintegrated. I guess it differs from one recording to another.by AP - Vanity103HD & Lite (discontinued)
The best way to get stereo is play stereo content whenever possible (SACD/DVD). If there is only multi channel content available I would suggest to leave it to the OPPO to do the downmixing by selecting appropriate speaker config/downmix option. The Vanity module can do downmixing only for multichannel DSD, nothing else.by AP - Vanity103HD & Lite (discontinued)
Yes, the concept of AES output will be the same as for the previous versions, but the output circuit modification will be much easier. From the extra features we will most likely implement the volume control (dithered with full 24 bit accuracy) and filter selection from the player's menu and a multi channel I2S output on an on-board header.

Yes, filtering is one of many possible applications. At the moment the number of taps is limited to 2048. Regards, Pavelby AP - News & Announcements
Hi all, Here is something new again! Probably not as much interesting as the Vanity203HD, but I want to show you anyway For easier evaluation of our IP cores and any custom algorithm development the Audiopraise team has designed this universal FPGA board. There is a mid sized FPGA from the Spartan 6 family, plenty of digital audio inputs and outputs (one analogue output too) and our digital clby AP - News & Announcements
Hi all, Just to shortly recap this thread, we have the proto boards back from production and now we are working on the FPGA and MCU software. Once the software has been finalized it will take 5-6 weeks to full availability, again via JVB. They already have a pre-registration form. Use this form to make sure you get a board from the first batch. Any questions, please ask here. Regards, Pavelby AP - Vanity203HD (discontinued)
Here we go, the Vanity203HD is born :-) There have been a few updates of the circuitry such as larger FPGA, more powerful regulators, higher precision DAC for the oscillators, onboard I2S output connector and USB interface for software update. Now the remaining piece of the puzzle is the FPGA and MCU software update, which we hope to get done in the next few weeks. Please bear with us, we areby AP - News & Announcements
Hi Rudi, Yep, we have a firmware version for Vanity93 and 103 with DoP output. The proto board for UDP-203 is in production and we hope to make it available in the second half of the year. Please have a look here. Regards, Pavelby AP - Vanity93HD & Lite (discontinued)
Hi, Yep, it has been a while. We are still waiting for the prototype boards to come back from production. They should be in at some point next week. I will take some photos and post them here. The connectors are the mostly same, but physical dimensions and connector positions are slightly different, so you cannot fit Vanity103 into UDP-203. It would not work anyway, since the DAC and communicatiby AP - News & Announcements
I am afraid the VanityHd can output only what it gets from the player, which is 8 channels, nothing less, nothing more. The release date is not known yet. We already have the UDP-203 on our bench, but due to some new features it will take a couple more months to have a finished prototype. Production will follow shortly. The progress will be reported here once we reach the prototype milestone.by AP - News & Announcements

Only four reservations, hmm, is everyone waiting for the VanityHD203 ?by AP - Vanity103HD & Lite (discontinued)
Hi JunTIAN, Sorry, it cannot (or it can but with no purpose). The VanityHD has to lock its clock system to the OPPO in order to output bit accurate data without sample rate conversion. It might be possible to output the master or sampling clock so you can clock lock a downstream device. Regards, Pavelby AP - News & Announcements
Hi Captain, Thanks for your appreciation. Regards, Pavelby AP - Vanity103HD & Lite (discontinued)
Hi, The VanityHD does not perform any sample rate conversion of PCM material. Its purpose is to output bit accurate data. You can use 16/44.1 NOS DAC only with 16/44.1 material (CDs). Regards, Pavelby AP - Vanity103HD & Lite (discontinued)
Three reservations so far, a few more to go...by AP - Vanity103HD & Lite (discontinued)
Hi Doug, Maybe I am totally wrong here, but the OPPO should be capable of down mixing PCM channels based on your speaker configuration in the menu. With the VanityHD board all downmix options and capabilities for PCM based media rely on the player itself. Only for SACD playback there is the VanityHD software version with 4.0 downmix option which mixes center and sub into the front two stereo chaby AP - Vanity103HD & Lite (discontinued)
Thanks! Looks very well doneby AP - Vanity103HD & Lite (discontinued)
Hi Captain, The latency of the digital reclocking is mainly the latency of the FIFO buffer. The buffer is 32 samples long and under ideal conditions the FIFO utilization is kept at 50% (in the middle), thus 16 audio samples. For PCM material there is only additional IO delay of about 4 samples. Therefore the time delay depends on the sampling frequency and is approximately (assuming 20 samples dby AP - Vanity103HD & Lite (discontinued)
Hi all, As most of you may have noticed already, the new UDP-203 started shipping before Christmas. This is the time for us to stop manufacturing the Vanity board for the old player model (103). It is because you can no longer buy the BDP-103 from the official distribution network and who wanted to buy the Vanity board has done that already.
