Oh wow! You must really like @Paul and after chatting with him this past weekend at RMAF I can see why.
How did your comparison go?
As I remembered, the ultraRendu/Teddy Pardo 7v PS combo with the Bridge II card pulled from the DS has proven to sound quite a bit better than using the Bridge II card. MQA has to proven to be a bust for me so I don’t mind giving up that feature.
I am now getting ready to test HQPlayer (imbedded in my sonicTransporter i5) with the ultraRendu and Roon to see how that sounds. There are many people out there that think Roon/HQPlayer sounds better than Roon by itself. The Roon/HQPlayer setup bypasses RAAT entirely so I am not sure how much of that is how HQPlayer processes the music files and how much is bypassing RAAT.
Does anyone out there have a favorite filter setup for HQPlayer and the DirectStream DAC? For PCM, do you prefer upsampling to max rate PCM or to DSD128?
Here is what I am using now:
Interesting issue. Some say that the Auralic Aries sounds better using Bubble DS or Lightning DS than with Roon.
The issue seems to be that without the RAAT support, the Aries is given a playlist, and then plays on it’s own without any further involvement from the player program. This includes pre-buffering into a 2GB cache, and then playing the music from that cache, much like the DMP.
Roon/RAAT, by contrast, feeds the track to the Auralic in real-time.
Sounds like HQplayer might mitigate that issue and let the Aries work at its best.
Try the Poly-sinc-ext2 and sinc-M filters. They are very similar but the sinc-M wins for me however, it has a 8 seconds buffer/delay which gets annoying but doesn’t matter if one listens to an album straight though.
I only upsample to 192PCM as that is all my I2S board will support, nonetheless it sounds better to me than Roon straight. Also try non-upsampling with HQP, set filters to none and dither to none. Oh, I can detect no difference between the dither choices with the DS. I suspect the DSD upsample make dither irrelevant.
FWIW, I run HPQ embedded on a Pink Faun 2.16x with only I2S output to DS.
Oh, I see you are running ext2 now. Compare it to sinc-M.
I just tried the sinc-M filter and I find it quite good. It does not use much CPU either. I get about a 6 second delay. I play mostly full albums so that is not much of a problem. It’s not much fun though when I am randomly paying tracks. It’s a good thing I don’t do that very often.
Thanks for the suggestion.
Nope. The filter setup I like best, so far, is poly-sinc-short-mp/NS5 with all PCM content upsampled to 352.8k. Using this filter setup with my sonicTransporter i5 (w/HQPlayer embedded)/ultraRendu/DirectStream combination is SIGNIFICANTLY better than when I was using the Bridge II card and no HQPlayer.
All I can say is “Wow!”
Paul…Anything on a DS update? 10 months seems like an eternity…
Well, I can tell you I heard the start of the next mountain top just before I left for London (where I am now). It is breathtakingly good - without a question the most significant code Ted’s ever written. It’s a new ballgame. Darren Myers lost sleep so lost he was in the music. Fingers crossed we can release next week.
Did you also try it on the DSjr, PMac?
Man,that’s great news Paul…can’t wait… and thanks guru Ted!!!
Thanks, Ted and Paul, I did not think it could get any better than Redcloud!
Thank you to Ted for keeping us moving forward! I can’t wait to hear his latest creation.
Wooo Hooo!!! Can’t wait!!
How exciting! We’re getting an upgrade for free. How often does that happen in one’s life? That’s one of the real value virtues of PS Audio.
Hey Ron,I got a lovely upgrade when I married my second wife…not free though…
What’s better than that, Mark? Lucky man!
bootzilla - I just went from Mconnect streaming to Roon Nucleus+ w/ Sbooster plugged into P20. Holy crap is it amazing. It took 30 minutes to gather all the meta-data (initially) and I only have 6,000 files on my NAS. I LOVE STREAMING! I am just blown away! Another upgrade I would pass out… In addition, I have not even loaded the “sweet” BHK tubes yet… want to wait a year to get it all settled out and then hit it… To think I was going to add a Basis turntable to the system. I am so glad I don’t have one sentimental bone in my body… dodged that time crushing components (turntable, cartridge, preamp, table isolation platform, cleaning brushes, cleaning machine… and endless time cleaning…)… WOW, that would have been serious drama… in addition, I have had my system (including DMP) for 6 months and have bought (3) SACDs. I thought I would buy a lot of SACD cause the streaming sound quality would be degraded compared to DMP. I stream 99% of the time and on occasions 1% SACD or CD. Since I have just re-ripped (dBpoweramp) my 275 CDs, I can’t wait for this upgrade. I am so glad I have such a small collection of CDs and zero vinyl (sold 20 years ago).Ted is a genius and Paul is the man!
Also, I just ordered the Sbooster Ultra for the MKII and will install that next week. I thought I may have an issue w/ MKII power output and Nucleus+ streaming w/ DSP filter. After 15 hrs streaming w/ DSP engaged (parametric, not convolution filter), the Sbooster was not even the slightest bit warm.
Could you already share the list of improvements in the upcoming release of next week?
- The new upsampling coding
- ticks/pops in PCM to/from DSD transitions
- a user selectable polarity switch for the I2S inputs
- Better distribution of resources in the SDM?
I usually do the DS Sr first, then it takes only a day or so to build the Jr version (most of the time.) Most of the files are shared, but some have a few differences that I need to be careful with. Then there’s the time it takes to get the 20 builds and the day or two (or three?) that it takes for PS Audio to listen…
