Beolab I've had the opportunity to hear these speakers at the pre release party here in Beverly Hills, LA (invite Only  ). I was quite excited about the event, considering it had what I thought ideal parameters for a acoustic transducer. The ability to integrate and manipulate listening window. Granted it was not the most ideal setup. A bit noisy from the busy Rodeo Drive, MP3 only, I did not find it special. Also a sense of DSP failure... too many transducers, the wide dispersion was disappointing (uneven power response)and the narrow mode was decent, but nothing special for the asking price or even less than half of it. The image density was poor. The SNR was as good as a decent car stereo. Again this was with the shortcoming as mentioned. Did you get to audition it? I would be interested in your experience  Best, VJ *Edit* - forgot, the above was also confirmed by a second pair of ears1, a friend who I had invited. He's heard my old set up... I've not yet heard them, only watched the video. There is some Youtube material of audioshow demos that could give a faint impression. I've subscribed to a Beolab90 tour demo maillist because I wanted to hear the merits for myself. To be frank I'm not that surprised by your findings of the demo, theory is one, execution is two. I became worried at the class-d amplifiers part. They are able to make everything sound like MP3 (maybe that's why they choose to demo with MP3). And the demo itself? A missed opportunity? Different target audience? No room treatment eh? Though I have great respect for the research and design effort, this never would be a speaker for me. I'm more of a "less is more" kind of guy. This worked for me all the time. regards, Coen |

You can promote a speaker without marginalizing your audience.
... (if this is directed to me)... No way! Please be a room treatment evangelist! I've my share of room problems too. I've never being able to give left and right completely the same balance and have great stereo at the same time. The merits of room treatments are well advertised, but you rarely encounter a room that has been "treated" for good audio (save for some voodoo patches or curtains on the wall -no wife!-). I never followed up to my plans to make a diffusor, I guess electronics are much more sexy to me. In the end the acoustical room correctors make a lot of sense in a stereo setting where we aim for identical response. As I learned from the better part of the video speaker placement has a large influence in the sub 300Hz area. No way that is going to be the same for each speaker in a real untreated room. regards, Coen The low end is also what I was aiming for. No way I like room treatments... that's why I restrained from it all these years, trying all kinds of tweaks to avoid them. Yes at present it does look imposing, but luckily its a dedicated room, so not much heat from the wife There is really nothing sexy or exciting about room treatments. These huge items are suddenly occupying space in the listening room imposing their presence... The idea was to tame the bass (which was not too bad + 6-8 dB in the upper bass, otherwise flat to 20 Hz), and the acoustic specialist argued his way into the diffusers, and I obliged. And this is where it gets interesting .... ofcourse bass was increased without smear, but more importantly how things changed with the mids/highs. Diffusers add some critical benefit in the frequency, spectral/power and time domain. Any micro/nano inconsistencies with the mids and the highs which affect image localization, temporal resolution, group distortion, timbre recognition, flutter echoes are reduced to a point below threshold. All of a sudden the system is flying. Bugatti on a race track vs a back country road with potholes.... Therefore the proposal for the new finding is as follows: " Reflections are fine and dandy for non-critical listening, or systems with lower SNR (I don't know the threshold) ... maybe (-)96 dB. For the extreme detail provided by the Phasure DAC, these reflections actually are very detrimental. Adding acoustic treatments -- for the first reflections will greatly decreased room associated noise, not only bass, but also mids and highs. This also allows for listening at much higher volumes before it gets too loud, or loss of musicality"Evangelized yet?  |

I had a good friend of mine visit for a listen .... Few of his comments... "VJ!!! .... these don't sound like anything before (he's visited me several times before)" "I don't think I've ever heard sound like this from 180deg or beyond" "You have achieved the absolute purity of sound" "I hear no glare whatsoever" "Vertical soundstage ... that's a fist time ... nice" "No listening fatigue" So well confirmed.... Next level up without question is acoustic tuning the room. Plan it with the B'ASS Hope it helps some ... VJ |

Another year has passed so quickly I am for the last year/s truly enjoying the Oreleo/phasure experience. I have had Grammy winning artists, Recording engineers/ultra high-end speaker manufacturers, John Doe speaker manufacturers, novices all visit .... with great feedback Although difficult to describe I would put the musical presentation as acoustic virtual reality, the equivalent of visual virtual reality ... A picture speaks 1000 words, most speak about the walls disappearing, haven't heard anyone describe the floor and the ceilings are disappearing or something like this .... |

Thanks to You and the gang, I've discovered/enjoyed more music in the last year, than years before combined. |

Happy New Year to one and all Still enjoying the Oreleos. Just added the eDelta power bank and running the “entire” setup off the grid B-). Overall increased energy which is relatively stable across the audioband. So soundstage is more forward and everything louder for the same volume. The imaging is not as wide as before which I suspect is related to increased reflections. Nonetheless totally enjoyable. Cheers! VJ |

Following up on the eDelta power bank. I have the "entire" system running off the grid for the few weeks. Minor hum from the speakers have drastically reduced. Right now there's only minimal fan noise from the XX music server at baseline. It's s quite incredible that I'm able to run these massive speakers/amplifiers, the music server, and the DAC with the power bank. Pure battery provides about 5 to 6 hours off music. However right now it is connected in the UPS mode so once in a while the battery automatically recharges. Although this might be bothersome occasionally during the quieter part of the music passages (fan noise), it is inaudible during playback otherwise. One thing for sure, the signal to noise ratio has significantly improved. |

Ehh ... wow ?
VJ, I hope you realize that you're working with the first XXHighEnd PC "with fan noise". The Mach II (no fans at all) and Mach III are completely silent.
Besides that, you don't want to know the improvement just because of the PC alone. It is more important than a DAC these days. I am serious ...
Best regards,
Peter

Hi Peter,
The battery itself has fans and that's loud when it's charging.
The PC fan noise is only barely audible at baseline. I can see at times the PC activates the battery into recharging .... making me think power surge ...
There are pending upgrades ... I know ... in due course.
