I figured I'd share this, as it had me pulling my hair out for weeks, and I'm still not sure why it's happening.
I have a PT-100 that sits between a Bluesound Node 2 and a Crown XLS 1502 running my Infinity Intermezzo 4.1t speakers. I decided to purchase a MiniDSP DDRC-22D to add into the signal chain to take advantage of Dirac room and impulse correction.
The problem I was running into was that for some reason the Dirac unit was completely killing my sound stage, making everything heavily compressed towards the center, literally making the sound stage about two feet wide. After spending a lot of time in the MiniDSP forums trying to figure out what was going on, it turns out the PT-100 was the culprit.
Running the Bluesound Node2 through the analog inputs on the PT-100 the sound stage was great. When I switched between the analog and digital inputs (since the DDRC-22D is digital only) to compare, I would always get that heavily compressed sound stage. Finally I figured out that when I power on the PT-100 with it on the digital input the sound stage is great, it's only when I switch between analog and digital with the unit on that the sound stage compression happens when switching to the digital input.
I'm not sure why this is happening, the unit correctly identifies the 24bit/96khz stream coming out of the DDRC-22D whether I power it on in digital or switch back and forth, but if I switch inputs at all with the unit powered on I get the heavily compressed sound stage on the digital in (it doesn't ever seem to effect things on the analog in).
Is this some sort of firmware bug?

Best bet which of course I`m sure you know is give Emotiva support a shout, I myself have never had that sort of issue with any equipment but hey with all this technology there will at times be issues, even the odd ones like yours haha.

My new PT-100 is showing a similar behavior. When I switch from any other input to the analog AUX input, which is where my video comes in, the sound stage compresses to the width of the TV. When I then cycle the PT-100 power, the sound stage returns to normal, which BTW is excellent. Going from AUX to the analog CD input with the power on does not produce the problem (I haven't tested other combinations). It's minor, but it does mean that I don't use the Trigger output to control my amps since I don't want to flip them off/on more than is necessary. Very strange.
As for the PT-100, the sound quality is excellent and the dynamics are great, although I did find the clarity and openness of the DC-1 audibly better than that of the DAC in the PT-100 and use the DC-1 as the DAC for my ERC-2. However, the FM menu system is so kludgey and erratic and following the manual so difficult that I may look for a vintage tuner with knobs so I can avoid raising blood pressure while changing stations. My Sony FM/AM Walkman is "easy as cake" compared with the tuner menu system on the PT-100.

Glad to hear I’m not the only one then. I submitted a ticket to Emotiva support, haven’t heard back yet, I’m assuming they’re investigating.

Hi, everyone... i am sort of having similar issue with my recently bought system, just about three months ago,
A-300, PT100, B&W 683 S2, LINN LP12, and for digital I played through Macbook pro via USB connection.
For first month or so I sounded as sound from heaven, incredible soundstage all over the room with just 35% of volume, clarity and definition in digital as in analogue.
But all that is just gone, no idea what wen wrong, I contact my local dealer and they will provide me soon with another PT100 to give it a try.
At the moment I am quite disappointed that the sound has changed so dramatically but in my case it is not and on off issue when I switch from different sources and quality changes...
Any ideas about this issue?¿

Any ideas about this issue?¿ Three months, that's about 2 software updates ago on the Mac, checked the output settings?. Or it could be the USB interconnect, tried another one? What about other sources, same problem? Cheers Gary |

So, I have just waiting for another PT100 from my local dealer and see what happens. In the other hand about the B&W , all the drive units of both speakers seemed to work, so it is hard to think that it would have something to do with it. Thanks for you comments. Javier |

I have just try the headphones output for the first time, I was not impressed at all, kind of the same muddy and compressed sound that I get through the B&W
Does make it sense that... it proves that something is wrong with the PT-100??..., it was via Macbook and USB connection...

Sounds like a call to Emotiva would be your best bet.

Hi, guys......
I've been trying to follow this thread, but I'm getting a little bit confused about what's going on.....
One person seems to be talking about experiencing a narrowing of the sound stage (which would mean reduced separation).
However, if that's the case, then there's no reason why it would sound "muddy" or "compressed".
(A narrow sound stage just sounds sort of like monaural..... but wouldn't necessarily be muddy or sound "compressed".)
Likewise, I'm a bit confused by the original post by tutetibiimperes.
His experience was that everything sounded good when listening through the analog output on the Bluesound Node... connected to the analog input on the PT-100.
But it didn't sound good when listening through the digital output of the DDRC-22D connected through the digital input on the PT-100.
However, he didn't mention trying the digital output of the Bluesound Node connected directly to the digital input on the PT-100 (skipping the DDRC).
And, even then, are we sure that the analog and digital outputs on the Bluesound Node sound identical?
My first thought would be to try the PT-100 with some other source that I'm more familiar with (maybe play something directly from a computer).
Let's see how the PT-100 sounds when we do that.
Perhaps you could post a few more details....
For example, the music you were playing, and the source, and what sort of connection you were using.

My only gripe with the PT-100 is the remote. How hard would it have been to supply a decent remote? I haven't tried using my Harmony remote.

Javier Hi again everyone, I have just got a new PT-100 from my local dealer and the issue still persist, so what's next? maybe the A-300 power amp? That make that muddy and powerless sound...any guess ? |

Hi Keith, Thank you for the response, I haven't actually followed this thread in a bit since I found a work-around that I'm happy with. The initial issue was yes, things sounded good on analog run directly from the Node 2 to the PT-100, but I was getting the heavily compressed (narrow) sound stage on the digital input running through the DDRC-22D in the middle. After playing around with it for a while I discovered that the compressed (narrow) sound stage problem only manifested if I started out in analog mode, then switched to digital, or switched from digital to analog and back to digital. If power the unit on and it's already on the digital input, everything sounds great, and there's no compressed sound stage running through the DDRC-22D. It's only when the unit comes back to digital from the analog input without power-cycling the PT-100 after switching it back to digital that the problem manifests. |
