Hello Fellow Mac Users

In my understanding with the drivers, you should be able to upsammple to the max. possible sample rate of 768kHz.
Can anybody confirm that this is either working in Audirvana or HQ Player?

Regards, Michael

As a long time lurker on this forum I am motivated to register and respond that the driver version 2.7.0 that Peter sent me is working without any ticks or unexpected behaviour on my system...
OS X Yosemite + HQPlayer on Mid-2010 Mac Mini up-sampling to 384 with cpu load around 25% to Phasure NOS1a.

I allready PMd Peter,

I did not try the 2.6.0 but the 2.7.0.
Installation run very fast. After the reboot the NOS1 was recognized and music playing within the minute!

I've let it play while messing around and noticed that there are tics with certain tracks with A+ and interruptions with a "krrr" sound associated with cursormovement. This is on battery mode. In "slow" filtermode (less cpu intensive), extreme priority and/or all other applications closed the ticks seem to remain. Not saying this IS about the driver but it could be.

regards, Coen

Hi Joachim - good point and sounds great, that is what I had in mind to do with my "laser" but the problem in my room is the reflected sounds from the side walls are only 4-8ms behind the main incident sound. And what is worse is that it is different left / right. That means my poor brain is totally confused (not unusual that!) as to what it is listening to. So maybe when I go to the trouble of getting the speakers perfectly lined up (and get a head brace to keep my head in the perfect position ha ha) I need to treat the room for reflections - I will see how much enthusiasm I can muster.

Cheers

The only slightly odd thing is the sound sitting in the "sweet spot" between the speakers - there are some phase like effects just moving the head slightly. I just wonder if it is necessary to get the speakers exactly positioned now to get best effects - I will get the lasers out and see how accurately I can set them up. But hey that is a trivial observation this sound quality is simply stunning.

Cheers

Hi,

some loudspeaker manuf. (Ascendo with their System M5-S) are adjusting the position of their speakers very accurate in dependence to the  "sweet spot" of the listening position.
They are measurering the distance from the left speaker plane  to the left ear, and from the right speaker to the ................ .

The sweet spot is (with the adjusted placement of the speakers) the only perfect listening position in that room. The signal from the left speaker is a "mirror image" of the signal from the right speaker at that place (with a pink noise signal).
 At other positions we hear different "signals" due to other/different running times to our ears.

The possible “off axis“ listening position is not the best place for serious listening sessions, but might be a good location for „easy listening“ during „studies“ on an iPad or in books, newspapers.

And, as Peter wrote, when we are listening to very loud music (from the room) outside on a veranda with the present configuration, the sound seems to be LIVE.

Coen,

As it turns out (only now) the new driver does not work on 10.7. 10.8 should be OK but was not tested (anywhere). 10.9 and 10.10 has been tested but not by me because ... I'm on 10.7.

Can you please test this ASAP ?
I just sent you the driver (in 2.6.0 version as you will see it for the Mac).

Thanks a lot, also on behalf of others ...
Peter

But otherwise I would have suggested exactly like you say now (see quote). *If* there's a GPU in there !

Confusing terminology, but the i5-2500k I use has an onboard (modest) GPU aka an IGP. When no videocard installed the BIOS defaults to the IGP for video. Powerconsumtion wise this setup is an advantage, but it didn't sound like that.

Regarding the RDC, I thought that folks were using it with the NOS1a upgrade?

Brian, not that I know of for explicit "a" reasons. All I know is that many use it in the first place.
I for sure know one : Me.

So it is only that the NOS1a 100% allows for it now, but the XXHighEnd settings for it are doable but not intuitive (is anything ? swoon) and I did not lay them out (since the 1.186-i version for it is not official anyway).
But working on THAT ... Happy

Peter

In fact I found it quite annoying this "beaming". So I mostly listen from the kitchen

I used to get this with the previous interconnect but not quite so marked (more detail now!) anyway as you say I probably need to straighten the speakers somewhat but that brings other problems ..............

anyway it is not a significant problem but I will try is more beer!! that may help.

Mind you I have an i5. My take is that the GPU on the CPU got activated again by the removal of the videocard with detrimental effects on SQ.

Hey Coen, that was the first thing slipping to my mind. But then your Sig says "No IGP" and although I had to guess its meaning I thought of No Internal Graphic Processor. This combined with an I5 of which I thought "isn't probably even in it (GPU)" ...

But otherwise I would have suggested exactly like you say now (see quote). *If* there's a GPU in there !
