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 Paul
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. Joachim

Hi Paul, since I'm using a laptop (battery removed) the "sweet spot listening position" is not mandatory anymore/again and I'm sitting in my prefered "off axis" sofa, AND the SQ is much better than with my PC. It is another/higher league. Joachim

Hey Joachim, I'm also interested in your impression of the RG 223 solid, silver coated, copper cable you ordered.
Brian
Hi Brian, after a "break in" time of appr. 10 days the SQ improved a "hell" and the sound is really amazing, much better than with the H + S cable. Voices, mids and basses (kick drums) are great. Since Mani and Paul are on "Cloud 9" with Peters Blaxius BNC cable I have ordered a pair for a comparison. Joachim

Ultimate Audio Playback / Phasure NOS1 DAC / Re: NOS1a and Q5 & W7 vs W8

Hi,
I also believe that the PC supply has a dominant role in suppressing this noise (or by not doing that). I am thinking right now about a linear base supply and switching local regulators. These linear supplies are much less tightly coupled to the power line. For an all linear supply I have to get a new system with less power consumption.
Regards, Coen
Hi, This might be (is) the reason that the SQ with my laptop is better than with the PC, much better. The laptop sees the 19Volts only. Now I have to look for a linear power supply for the laptop. Joachim

Ultimate Audio Playback / Phasure NOS1 DAC / Re: Req: any USB cable tips?

Hi Joachim,
Are your sure that a USB cable without power will work between the PC and the NOS1(a) ?
2 years ago I had an Sotm USB 3 PCIe card that has a switch to allow sending the 5V power in the USB cable or not.
To establish the connection it was necessary first to allow the power to flow between the PC and the NOS1, then (and only then) as soon as the 2 components connected, I could switch OFF the USB power...
I would test with an ordinary USB cable (on which the power is "masked" with a thin layer of isolation tape or plastic) first just to be on the safe side...
It seems that some dacs do not require this, but the NOS1 seem to use it at least for the connection time... (Peter ?)
Alain
Hi Alain, somewhere Peter wrote no USB power connection between the PC and NOS1 is needed. I will look for his remark. I bought this cable (I think Juan recommended it) at NOS1 times and there was a benefit to hear. There aren't any problems with this cable for the NOS1 and NOS1a in my system. Joachim

Now they are all over the place. Easy difference *again* ... And for the better. Peter So "NO COIL" is an advantage. Right? **** Hi Peter, no answer is an answer. I have interpretation problems with "they are all over the place" , because it was your intention to uncoil the cable for a comparision. You still have Mani's 10m cables. Do you have the possibility to test the "old Orelo MKII" loop. (DAC 33 Ohm RCA, your 75Ohm cable and the old RCA connection at your active speakers, with and without coiled cables) I think we, with "normal" speakers", have to look for other cables. I will try a 50 Ohm BNC cable with a solid copper wire, double shielded, and the dielectric mat'l is PE foam. The length is ???? due to open test results with "coiled" cables. The dia of the cable is 10,2mm. A German manuf. is selling such a cable for €100,00 per 25m. Or do you have another proposal for us "outsiders" Joachim ****

PS:
What I did not tell, but what was in my mind as "the" subject this morning, was this :
*If* this coil thing does something and it does it for the better, we will be totally lost for the next 6 months because we may find ourselves trying various windings of this coil. And then not to speak about the total length which makes the variations infinite to begin with. But outside that we can have smaller and larger windings, two "sets" of them or even three and all should do something else. Mine is put flat on the floor, but putting it upright will imply other resulting properties. Let it float ...
So just saying ... we better hope that "un-coiling" this gives a better result or otherwise we addicts will all get crazy.
Peter
Hi, funny, this coil was in my "arrangement" since the beginning, and I always considered this as a disadvantage. Refer voices. The song "Roxanne" by George Michael is from somewhere else now. http://www.amazon.co.uk/Songs-Last-Century-George-Michael/dp/B00003CK6Z/ref=sr_1_1?s=music&ie=UTF8&qid=1413033738&sr=1-1&keywords=george+michael+songs+from+the+last+centuryJoachim

Hey Joachim, I'm also interested in your impression of the RG 223 solid, silver coated, copper cable you ordered. It appears that the conductor of the RG 223 is smaller than the RG 142, solid, silver coated, copper I've been listening to.
Hi Brian, you are right, both types seems to be identical, except the core is 0,05mm smaller at the RG223. I will report and hopefully the SQ will be lifted again. Joachim P.S. Here in Germany is a reputated audio cable manuf. "HMS Electronic" ( http://www.6moons.com/audioreviews/hms/hms.html ), and the mastermind Strassner wrote some critiques about electrical cables in general, but in German only. His biggest concern are the "RF" immissions into the cable, because every cable is an antenna. (sample: a PVC coated wire is attached to most radios as an antenna)

So at this moment this is the idea :
Mani has two NOS1a's and accidentally his second came in two weeks ago (was it's turn) and Mani is going to try. So all will be applied for him, just like I have it myself. The difference ? his interlinks will be 10 meters. Mani, unlike me, is also used to the more expensive interlinks. So he will be able to judge whether it is all and 100% "for sure" for the better. And that at this very different length. If he says "OK !" then that's a start. But only that, because now his amplifiers are the same as mine. Mani is in a convenient position because of his two NOS1a's. So he can compare. Also accidentally he can have two parallel inputs at the amp (speaker). So he *really* can compare.
Hi Peter, that's a good idea for us "No Orelo MKII " owners and Mani is requested to be the pioneer. We would like to know if there is a the difference of the SQ between his present 50 Ohm Huber+Suhner K_03252D (inner conductor: single strand, solid copper core coated in silver) cable and your new cable. Thank you in advance Mani for your kind help. Joachim
