UPDATE:
This is the ODSE vs PS Audio Direct Stream comparison.
First off. I started with the DS using the older firmware and then update to the newer firmware so that I could hear the difference. The update had a hiccup or two. But then I tried to upload the original firmware again, and I crashed the DAC; like nothing worked, touchscreen was unresponsive.... That was disconcerting to be honest.
I described the PS Audio DirectStreams physical attributes before, so I will not repeat myself. Think Perfect Wave or Perfect Wave 2 with a different name silk screened on it and a more elegent, simpler touch screen layout and your there. The DS is very well built and buetifully finished. See my earlier report on more specifics.
Sound wise, the DS had about 460 hours on it +/-. More then enough for burn in based on the general attitudes reported on the many forum threads growing around the DS. Here is what I found...
original firmware:
In some ways, I thought the DS sounded like the ODSE. There was no brightness, no harshness and nothing offensive about its performance or sound. Nothing that made me fatigued or pushed me to stop listening. I found myself very engaged at times to the notes flowing from my speaker drivers. Up top, the highs were seamlessly extended and correct; never overly pronounced nor subdued. The mids were where they should be; musical and with correct tone and texture. The female voice was beautifully reproduced on more then one occasional and the deeper male vocal was equally well reproduced. Low frequencies extended to the netherworld and were well controlled; not overly grippy and not loose. To be honest, it did everything right. I found that trailing and leading edges were not quite as well defined as with the Big6, MA1, Aeris or ODSE. There was a tubelike presence about the music that invited you in and said, "pull up a chair and stay a while."
The soundstage was wide and deep and put me solidly in the middle of the theater. The location of performers was correct (although I sometimes found them to be shifted slightly to the left of where I was used to. This was wierd because center stage was still clearly center stage at all times). Each instrument/performer had the correct sense of presence and space. Technically, it does what it is supposed to, and with aplomb.
Here comes the but.
But I spent a LOT of time listening and not that much time tapping my feet. It had a DSD sound, if that makes any sense. Now here comes my disclaimer... I have only heard DSD in uber expensive show systems and in a few friends houses where they spent time trying to prove to me that DSD was better then PCM because it just was, and "see, listen to this!". Maybe I'm used to the "shortcomings" of PCM and found the DSD to be too different to my picky ears. I was under the impression that the MA1 also upconverted everything to DSD, and the MA1 could not have sounded more different then the DS.
I listened for 2 hours, going back to songs multiple times. A few tracks on my play list really shined on the DS and every time I hit one of those, I'd rush back to my other tracks to see if I had missed something... But I didn't. To me, the ODSE and the Aeris were both better in pretty much every way. And I am pretty sure (even though I didn't do a direct head to head) that I would have preferred the Big6 over the DS as well. I will say that the DS did pull subtlety out of the music that the Aeris occasionally missed.
Again... My ears, my system, my opinion. Don't beat me up and don't write the DS off because of what I said.
Interstingly, I found that the DS occasionally had a hard time holding on to the data stream and I had to close my Amarra and re-open it to re-sync with the DS.
Also, the DS is quiet. I did not try to run it direct, but I ran it at 100% into my pre-amp and my pre-amp was consistently 8-12 percentage clicks higher then with the Aeris or ODSE to get the same volume. Noise floor did not seam to be affected by this, but it is worth noting.
Then I uploaded the newer firmware...
Interesting. Better in some ways and worse in others. Overall, the update gave the DS a sense of emotion and grip it did not have before. I agree with some other reviewer who said it sounded like the "presence" control was turned up. But I found the soundstage a hair flatter. The image stabilized and perfomers were pushed back to where I was used to hearing them. Dynamics also improved. It clearly became more engaging and I fell into the music more then I did initially. I listened for another hour or so with the update and sincerely enjoyed my time. Much closer to a contender with the firmware update.
Then I killed it. I tried to upload the initial firmware to compare again, and the software imploded and nothing worked. It tuned on, but thats it. Wouldnt lock, wouldnt take any touchscreen input. The lights were literally on but no one was home.
Time to switch back to the ODSE.
Hook her up (I am getting used to this since she's been in the systen for 6 or 7 weeks now). Locked right in, tuned on. Click click click. AND WHAM! I'm sucked right back in. Spine tingling, hair raising vocals. Eyes closed, swaying to the music. Conducting like an idiot in an empty room (you know you do it also!). I listened to 5 songs: 2 vocals, 1 jazz, 2 classical (ok, 1 soundtrack theme and 1 classical) and I just knew....
I packaged up the DS and emailed PS Audio for a return authorization.
Wait for it.....
And then I emailed Steve and told him to start production of my very own Overdrive SE with Hynes Regs and CUTF Coupling caps. Steve is working on some new stuff that will make it even better (can't wait to hear it!!!!)
Sorry all you Direct Stream lovers. Its a great DAC no doubt, and with the new firmware upgrade certainly getting closer to competing with the likes of Rowland, Empirical and such, but not yet fully up to the challenge. I was impressed by the improvement they could make with a firmware update. Being that it is completely software driven, its very cool that with the right software they will slowly and progressively improve the performance.
FYI - I am pretty sure the Rowland Aeris is also software driven. I bet that the right firmware update could make the Aeris untouchable. Which is amazing considering just how good it is right now! In a warmer system, or a system with tubes in the pre-amp or amp the Aeris is the way to go, no doubt.
But for me. With my ears, my room, my system I am excited and feel I have done more then due diligence in selecting my ODSE as my keeper DAC.
Of course, that all said, I have a wonderful DAC inbound in the DSD-S and cant wait to hear that and report on it. And I am waiting to hear from John on borrowing the Aesthetix Romulus SE, which I am actually dying to hear!
I have also already received suggestions for a litany of other DAC's and need to say no at some point. But since my ODSE will probably be 6-8 weeks (I think, maybe sooner) before it arrives, and I'm shipping the current Empirical Audio gear off to a reviewer, Im glad to get some other DAC's in to play with in the meantime.
I still have my Aeris up for sale and I am enjoying that thoroughly in the meantime, until one of you with a tube system buy it from me! ;)
And I will now put my PS Audio Perfect Wave 2 up for sale as well. So if you know someone looking for a good deal on a Perfect Wave 2, let me know... for $1400'ish dollars, its a great great DAC!
