DirectStream DAC General Discussion (was First Impressions)

Paul said "Glued to my seat" is a term I hear a lot from DirectStream owners. It's one I use myself. There's times when I just hide in Music Room One playing and finding new tracks, so good the system is.
When I'm glued to my seat too long my wife usually finds a way to un-glue me. Man...I wish she was more into listening to good music with me; Says she has no time.

Anyway… Hopefully I will be able to trade up to the DS one of these days. Had to work on a source upgrade first which I believe is finished now. The source did set me back some which will delay the DS a bit. Sure like the user feedback concerning the DS SQ. Looks good so far.

Paul: Don’t know if I’ll make the summer trade in deadline, but how long will you make the kits available?

P.S. Are you writing a fiction novel?

We, too, had a good listening session last night. Perhaps the best, most thorough listen so far.

20 days in, give or take time for thunderstorms and a hurricane, so I think we’re getting pretty close to that 500 hour mark.

There is no question that the DS has opened up very nicely. In short, most of the things that people had said seem to be true: Great soundstage and placement; incredible detail and clarity; more information than we’ve heard out of Redbook before. Although we still have 10 days on our trial period, I’m quite confident we have a keeper.

In the days to come, I’ll be swapping around some ICs, seeing if the Off Ramp will stay or go, etc. Sort of fine tuning, to the extent that we can.

There is only one thing that still causes me to pause a bit… that of the “bottom end” concern. It seems to be an issue on some albums, and certainly not an issue on others.

For example, based on something someone said, I put on “Billie Jean” from Thriller. I kept waiting for the oomph, the presence of the low end, the engagement. All I got out of it was the bright, clear, ticky-tick of the back rhythm. Nothing about it ever drew me into the music. Mind you, it was clear and detailed, but it certainly seemed to lack something important.

So, then I played “When I Still Needed You” from Anatomic, by Afro Celt Sound System (World Music, Peter Gabriel’s label.) The bass and low end was stunning; the sound was full, dynamic, engaging, and almost scary in how good it was. It proved that there is certainly no issue with the Vandy subs…

I guess another way to say it is, “When it’s bright, it’s very bright. When it’s not too bright, it’s very right.”

I know that we could swap the PWDII back in and get slam galore, but then we’d give up all that delicious detail. For now, detail is our choice, but there’s still something that leaves me feeling just a bit unsettled.

Any thoughts that haven’t already been discussed to death?

It seems to be important to use a strong computer to stream. If have tried to use my laptop but it lacks low frequencies. A desktop computer with a strong powersuplly can add low frequencies.

Thanks for that.

I use a Mojo Audio-modified Mac Mini. Power to the Mini is through the Mojo Joule III power supply. The Mini is maxed out on memory, has an SSD drive (music on external FW800), totally dedicated to music. Everything else has been deactivated.

I don’t think it can get much “stronger” for a computer-based music server.

Perhaps it’s just the recording? I listened again after writing the above… it doesn’t seem so bad as I remember from last night, but it still registers “high”.

Now that I think of it, I might have gotten the album off of HD Tracks, or some other download site. Hmmm, I wonder…

Don’t get me wrong: There is so much good, here. With Bethany & Rufus playing “St. James Infirmary”, Bethany was right in the room belting it out. Jennifer Warnes “Way Down Deep”, with it’s deep-throated native drum, rattled my pancreas. Bobby McFerrin on “Simple Pleasures” made me hurt because I thought I was slapping myself on the chest.

Come to think of it, I think this just falls in line with what others have said: If the recording is poor, you’re gonna know about it.

Welcome to the "what's going on here?" club, Rob.

Wijnand, IME this has nothing to do with the method of transport. Same thing can be heard regardless of using PWT or Ethernet, or USB. However, Rob, it’s my feeling that after the several hundred hours of burn in you can explore switching out ICs and maybe rebalance what you’re hearing to get back what you think you’re missing. I was able to do that, but at the very small price of losing some “listen to me!” attraction in the extreme high frequencies - which might be argued as something that would be out of balance with the rest of the range anyway.

Tony,

Yuppers… We’ll have to develop a secret handshake, or something. 101_gif

Later today, I’m going to bring in the PWDII just so that I can rule that out and send it back to PS Audio.

Then I’m going to try a couple of different ICs, not that my stable is large. In a way, I hope that doesn’t work out because I paid a LOT for the current ICs. Although I’m sure I could recoup my investment, there’s something special about them that I really like.

Of course, no decisions on anything can occur until I’m confident that the unit is fully broken in, and I don’t believe that has happened yet.

Also an excellent recording to appreciate the DS' ability to distinguish timbre. Its ability to parse out the electric bass from the drums when the bass enters is delicious.

Hi Rob,

I never heard about the Mojo Joule III powersupply. I have to look it up! Great to hear you have a serious streaming solution.

Something to try great stuff.

Hi Paul,

You’ve advised elsewhere to leave the DAC always on. Can you please clarify what “ON” is?

Is the DAC on if the power switch at the rear is left in the ON position even though the DAC is turned off with the remote?

I’m very sure he’s referring to the AC switch on the back panel.

The OFF button on the remote puts the DAC into standby and physically mutes the hardware (as does pressing the logo button on the left front of the DAC.)

Standby keeps the boards at the same temperature and in fact even when muted the DSD engine is still whanging back and forth from one power rail to the other to get an average zero output.

There’s not a lot different between going into standby vs. turning off the display and pressing mute.

Holy cow!!! Shine on You Crazy Diamond ripped from Roger Waters In The Flesh Live DVD. So good I had to play it again. This is a new album for me and takes me right back to my early days with the Floyd.

Ive only had the DS 12 days and not burning it all the time like you disciplined folks. What music is making your hair stand on end?

There was one cut the other night that made the both of us feel kinda high.

Can’t tell you what it was, though… I was feeling kinda high.

Seriously… it was so good it made me dizzy. Total immersion in the music with no grounding to speak of.

I suspect the kits will continue to be available at least through the calendar year.

Yes, I am writing a fiction novel. It’s fun!

Please tell me it’s some cool Science Fiction, or Steampunk novel or something like that! :slight_smile:

Paul, you have my attention. What are you going to leak about this novel thing you are doing? :smiley:

J.P.

I don’t even know what a steam punk is, let alone write about one. sad_gif

It’s complicated, probably not ready for public consumption. I am about 3/4 the way through the first of 5 books in a series titled Evolution. Take the work of Michael Crichton and Dan Brown for page turning action, and you’ll get the flavor of the book. Definitely a page-turning thriller. The first book introduces us to the main characters, sets the stage for the other 5, uncovers the great secrets locked away for 800,000 years. The first discovery takes place in Antarctica then moves on through much of the rest of the world.

If I do my job right it’ll have you hanging onto your seat. Been fun.

Relieved to hear that the title of your fiction novel was not ‘PerfectWave Amp Owners Manual’ devil_gif 65_gif

Now that’s funny! 24_gif21_gifThanks Frode.
