DSD MK2 Latest Mountaintop update! - Mount Blue Sky!

Thanks for posting, just realized my I2S 1 input had the channels inverted. I thought the hi hats had been on the wrong side!

Boy @tedsmith , you’ve really outdone yourself this time. :exploding_head:

Both FPGA and firmware update installed fine, but does not show up on screen afterwards. Did I do something wrong?

If the firmware update didn’t finish with only the blue light blinking many times before finally restarted then it didn’t happen. My attempts would have the progress percentage go to 100 but wouldn’t actually finish the update. Is this what happened to you, too?

Shut the DS II completely down and re-boot to see if the window changes. If not it didn’t go through the first time.

Where do I find the video?
Thanks.

See the first post in this thread.

Thanks!

So… I was skeptical things could get any better. I waited 24 hours to listen after playing music with my amps off to allow some “burn in time” and I was amazed. Deeper and wider soundstage, quieter background, much more focus and separation, tighter bass, smoother, more lifelike voices, more “air”, more and better everything that I probably can’t put into words. Thank you PS Audio & Ted! Wow.

Happened to me more than once, too :grin: Drove me mad the first time until I found the setting.

I haven’t noticed further changes with this OS update. Wow. Such a great revamp of an already great DAC!

You didn’t update the firmware to the latest which is 3.2.1

Don’t know if Ted’s monitoring or not but yes, only the one FPGA.

Got it now, thanks Paul!

A couple of days ago I posted my initial impressions of Blue Sky. My initial posting was with my Atma-Sphere Class D amps. Yesterday, after running my DAC continuously since the software update I sat down with a couple of fingers of a fine Bourbon for another listen. This time, I powered up my Cary Audio Founders Edition tube amps.
Unlike my Class D amps which pretty much sound their best at start up, my Cary’s usually take about an hour and a half. It is so noticeable when this occurs that even my non audiophile friends notice it.
I was and am extremely impressed with Blue Sky. It was a very obvious improvement using my Class D amps but with the Cary’s, it was jaw dropping, shaking my head in disbelief, goosebump time. Once the Cary’s warmed up I couldn’t keep the smile off my face. The presentation was totally immersive. My modified Tekton Design Ulfberht speakers are 11 feet apart and I sit the same distance from them. Even at that distance ,I was immersed in the sound . I was hearing small details on well known recordings I had never noticed before but it was the cohesiveness of the entire presentation that amazed me. The soundstage was more detailed, wider and more forward than before.
When I started being more serious about my music playback in the early 70’s , I never thought I could reach the level of music playback I have now. Many thanks to Ted, Paul and the entire PS Audio crew.

Since only a single FPGA is used, would this code have worked for the MKI or does it have a completely different specification? My Blue Sky upgrade installed perfectly BTW - I am quite impressed with the sound so far (noted lower noise floor, treble seems a little more forward, greater articulation of the bass - overall a very organic sound - Bravo!

The Bourbon did it, I believe :tumbler_glass:

No, the FPGA in the Mk I is a previous generation FPGA: a Xilinx Spartan 6. The Mk II uses a Spartan 7. Roughly the 7 has about 1.5 times as many resources and runs about 1.5 times as fast. But in the case of the filtering: The 7’s multiplier is 18 bit by 25 bit, the 6’s is 18 bits by 18 bits, so each “filter step” in the 6 uses three multipliers, but the 7 only requires 2 multipliers… The new filters are approx. twice as long as the Mk I’s and run at twice the speed… The Mk I’s FPGA was overfull, but we are using approx 1/2 to 3/4 of one FPGA in the Mk II (depending on which resources we might be talking about.)

And the Spartan 7 logic cells and slices have more logic, the multipliers (“DSP”'s) handle more bits, etc.

Good Bourbon makes everything more enjoyable!
