Phison Audio PD2 Preamp/DAC

Mivera Audio said:
1: Yes as explained already, the PD2 only has SPDIF and USB input

2: As explained in my previous post, my server is compatible with everything. USB, Ravenna, RAAT, NAA etc.

3: My server can send PCM via RAAT or NAA to a max of 32/768, and DSD 1024. With USB, max output support is 32/768 PCM and DSD 1024. With Ravenna max PCM currently is 24/384 PCM and DSD 512.

As far as USB vs the finest audio over IP protocols go, it will be splitting hairs trying to beat what Sonny has does with the PD2 USB implementation. As I said its the best I've seen in any DAC at any cost.

My server can do RAAT to any RAAT compatible DAC right now. As well as all the formats I listed earlier. This is today, no need to wait.

Blizzy your such a tease.......so what dacs are out that are compatible with RAAT and Ravenna and through what connection. That is the essence of the discussion.

Well here's a growing list of manufacturers with RAAT in the works:

https://roonlabs.com/partners.html

PS Audio is implementing it in their bridge as well.

As far as Ravenna, so far only Merging. In the future the Mivera Audio Purestream.

However any DAC with USB input can become RAAT compatible by using a Sonore Microrendu.

My first PD2 client is going to try one to see if it beats my free streamer.
 
I just realized MSB is on that RAAT list now as well. But not sure if it's possible to implement on the Blackfin chip in your renderer or not.

Now if/when you get your RAAT crankin and the world is full of DACS with raat compatible ethernet inputs to boogie with it, like I sad before, that will be pretty wiz bang, but we ain't there yet. TRUE or FALSE???

Ahhh, so the answer is TRUE. And regarding my original question about a perfect USB implementation maybe being equal to but not better than a direct ethernet to i2s I will take from your "splitting hairs" comment your answer to be a YES it may approach but bot be better. Now that was sure easy......

Blizz, keep up the good work you are definitely working on the right path IMO. Execution will be key.

To summarize my understanding:

If you can figure out way to get the Interface de jour (be it roon or whatever) married to the conversion-and-upsampling software de jour (be it hqp or whatever) on a PC that can deliver the bits via audio over ethernet to i2s direct, and convince the dac world to use the Ravenna input then I can state categorically you will rule the world.

Keep up the good work this will be fun to watch.

Of course there's much more to a complete system than just the digital interface. Having studied everything out there I'm going with Ravenna. However beating what Sonny has done with USB won't be a trivial matter as its tightly integrated into the DAC board.

As far as convincing others to use Ravenna, I don't really care personally who uses it. My server will be designed specifically for use with Phison and Mivera products.

I may consider making custom versions for select DAC's, but I will need to test them personally and optimize the server for use specifically with each individual DAC. I don't believe in the 1 size fits all approach.

Well I think I get it. On paper that is the digital solution of the future IMO (ergo my snarcky triceratops reference earlier to you praising usb).

And if you can make a top dac then you don't need anyone else. (Here is a secret tip: SHHHHHH be berry, berry quiet.....OK, here goes--- stick a dht in the output stage and people will think you have invented a magic sound making machine. I think the digital world generally is unfamiliar with the wonders of this magic tube so they will beat your door down to attain its bedazzlement. The only other requirement is a magic internet salesman to simultaneously pound every forum on the internet incessantly for months on end. You will be set. But don't tell anybody.......its a secret, SHHHHHH.)

Seriously, in a few months down the road I would like to hear what you have.

Personally I like to be open and honest in public with all of my ideas. This way the competition only has 3 choices:

1: Build something inferior

2: Copy my ideas

3: Come up with something better.

If they choose either option 2 or 3, we all win :)

Just don't show em your magic wiffle dust. You will be fine. Good luck Bliz. I would like to compare to MSB when ready. Thanks for your answers.

Thanks Paul. I'll send you a message when I'm coming that way. I plan on doing a U.S tour of in home demos after the server is ready.

Thank you very much Flex & Mike for an educational trip down digital road, I´m always happy to learn new stuff and have a peek at what the future might bring.

Speaking of the future, Sonny from Phison should consider making a stand alone DAC, seems to me he could make a killer product.

Nayayan, those two are the guru's. I am along for the ride. I will say this: if you are considering digital and value matters, you might want to pay attention to these boys cuz either the paradigm is about to wiggle or they are full of beans. I kinda think it may be the latter. At this point, who knows??? Fast times at Ridgemont High.

No problem Narayan. Yes that's what the whole Mivera Purestream I mentioned is all about. A pure stand alone DAC only with DA conversion on par with the PD2. Only utilizing the Ravenna protocol for a digital interface rather than USB. However, if Sonny wants to build something the same under the Phison name, I'll be on board. Sonny just isn't convinced that the "IP over Ethernet" protocols are a superior way to do things yet. So I figured I would have to prove it first :)

This I have not said at all.What i am saying is that I could stuck with support related to the owners network rather than the product.

Well competent dealers will make that a non issue. The latest "IP over Ethernet" protocols are as rock solid as USB. This is why pretty much 100% of all the top DAC manufacturers are going this way. Did you not see the list of RAAT supporters on the Roon website?

Tru dat. Thats why MSB stayed with Upnp even though it gots lost of nasty scabs on it. Other's are left fiddlin with the Bactine.

Yes but did you not see MSB's logo on the Roon RAAT list? I don't think it's there because they have future plans on taking a few steps backwards :)

I've made my view on digital interfaces is well known for a long time now. Sonny has come up with a game changer for USB as far as I'm concerned, but I'm not convinced it's better than Ravenna. This is why I'm so happy about the modular form factor and extension slot on the PD2. If you read this thread, towards the end was when I was testing Sonny's prototypes:

Yes we are in the information age now. The industrial age has passed. In order to succeed in the information age, you must keep up with the times. Biases only serve as handicaps in the information age. If you hold on to biases, you will find yourself in a huge cloud of dust before you even know what hit you in the information age. When you learn of something new and better, you must drop the old like a hot potato, and forget it even existed. And the sooner you do it the better. Because if you don't, others who are aware of the age we are in will slaughter you :)
