A bit stupid that the Supra is nowhere on stock else than in Sweden (as it seems). I never like to wait forever ...
So this is the only reason I did not try it myself - really.

I still need to hook up my wattage meter to see what my 2012 Mini consumes.

Today I wondered, but now I'm sure someone has the answer !

Btw, my XXHighEnd PC consumes 48.5W during playback (yours can do that too).

Regards,
Peter

PS: Please people, talk about Macs as much as you like. Matt, you're actually (also) an unexpected person because I never know what you really use. OK, now I know. This could count for many more who maybe don't "dare" (ahum) to tell about it ?

Allow me to show the below picture. This is most certainly not to get everybody's attention and motivate to yet upgrade AGAIN, but this one if officially there so it has a "right" to be shown;

Like I told earlier in this topic, it is nice that we got this far with it all, but I seriously don't know how to apply it to people in a consistent fashion. So before it is asked again : it needs the appliance in the NOS1 (that part seems doable for you out there but is to be tested by me) but it also needs the BNC connectors at the amp's end. This is way more tough for almost eberybody. Without the latter it is "guessing" while in the mean time you (or we !!) adjusted your NOS1(a) maybe without reason. So it all "fell over" me and I don't know how to continue really. This is rare (yes) and I don't know how to deal with myself. Like this post (or picture) maybe better shouldn't be there. But it *is* about vast progress if you ask me, so ... grrrr ...

99% of my Phasure NOS1 (now "a") usage has been under Mac OSX.  Peter did try the Audirvana+ player at one point, so he has recommended filter settings for that player if using the NOS1.  I tried to get HQplayer working but ran into an error after install that I couldn't understand or solve, so I gave up.

It gets worse.  Most of my music is played over Spotify with OSX up sampling to 384K.  Look under the AudiiMIDI utility for this.  This is a capability that Peter actually reminded me of, since I'd forgotten about it It's not because Spotify is ideal for SQ, but simply because it's a very easy way to hear new music.

Interesting regarding Peters recent comment that low-power computers may be ideal because mains noise can still affect sound.  The Mac Mini is designed to use much less than a typical PC.  Apple seems to prioritize this during development since it's always part of their marketing spiel.  The later models especially so, although I still need to hook up my wattage meter to see what my 2012 Mini consumes.

I've never felt OSX wasn't supported, but the NOS1 was designed for XXHE so that's where most of the discussion is.  No much to discuss on the Mac side, once you have your AudioMIDI and Audirvana+ settings correct.  It makes sound, better than my Benchmark DAC2 incidentally, but not as good as it can be under XXHE.

I put Windows on the Mac too, so I can use XXHE on it.  Easy to boot into that, but I'm a creature of habit and my personal music collection is only a tiny fraction of what Peter has.  Plus I still have the XXHE PC.

When I get some new speakers (Geddes), I'll do more comparing.  I haven't felt comfortable doing comparisons so far, since every speaker so far (at least 7 over the past year) has had some serious flaw.  Learned a lot, at least..

Enough blah blah, as Peter would say  Wink

Hey Mani,

I replaced the regular RCA input connectors in the Orelinos with the 75Ω BNC connectors

I recall a particular person living very close to your wife, who once made a remark towards two other guys living at more distance from your wife about "Bert's nomenclature". Has to be a UK thing ?
yes

beautiful balance to sound (maybe a little bottom-heavy, but this will be easy to adjust if I decide I want to)

[Edit: My (second) NOS1a, which I'll refer to as '75 B' from here on in, has had the 'Nick/Paul mods' applied to it by Paul, namely; a bunch of Black Gate caps, and a Dexa USB clock with independent PS. The Dexa really shouldn't make any difference to a NOS1a, but I cannot comment on the effect, if any, that the BG caps might be having on the sound.]

Yes. This is what I noticed myself, though a bit difficult to judge because I could only listen briefly to your 75B taking it cold out of its box;
I found the bass to be more than impressive - up to possibly a bit over. So I said "possibly" and I too can't really say it is because of the BG's. The Dexa shouldn't be of influence (but who knows) with the notice that you refer to the "USB Clock" (this might be not clear to everyone).

And Mani ...

A MASSIVE thank you to Peter. Man, where would we be without you?

... please keep in mind that it only took me a lot of time (and some $$$ as well - that not much dfferent from others including yourself) but that without Joachim the whole subject would not have been here.
But then of course I gracefully accept your thanks because it was something I could see working and *had* to make something out of it; almost more scaring than exciting because of the whole new subject (for me).
Possibly it has been more a subject of "see ? cables are a hoax" and now I can only hope that "tomorrow" nothing has changed your mind. And/but might you encounter an off-day, that happens here too - totally not sure why or how. Will be okay the next day. So just "announcing" it.

On behalf of more than me, thank you for the feedback !
Peter

I also just ordered the Supra USB Cable mentioned above.

Should be here within a week.

Hi Coen
Thanks for your feedback.
Why would you say that PCs are better for HighEnd Audio?
Is it due to the fact that you can select specific hardware like USB Cards?

I used Windows machines a lot in the past but switched about 6 years ago due to the fact that Mac Hardware is just so much nicer Wink My personal taste obliously.
And my hassle to maintain the system in the MAC is basically zero. Do not get me wrong, i do not want to start a MAC vs PC discussion, just my personal experience.

It just occured to me that when I saw in another thread here the photos of the gear people use, the PC usally had the least apealing look Wink

Hi Michael,

I'm with you here, but I only bought my first Mac recently. 60% of the decision was daily windows frustration and 40% because of the MUCH better look and feel of Mac products. My MBP is the best (& best looking) computer I ever used. I even went BYOD with the Mac in my daily occupation.
 
I still have and use Windows stuff (win7) predominantly for "High End" audio. There's simply no alternative yet. I wouldn't regret leaving the platform altogether but that's not an option today.

regards, Coen

But let's wait until Mani has a judgement. He will have all on Tuesday, but it will last until next weekend before he is there to apply the "amp" adjustments.

I replaced the regular RCA input connectors in the Orelinos with the 75Ω BNC connectors that Peter provided me. (Oh, and if Peter ever tells you that anything is a "no job", don't believe him.)

My (second) NOS1a came back with 75Ω output connectors installed (and a beautiful "75 B" inscription on its front faceplate). In the box was also a 10m pair of Peter's 'Blaxius' cables.

I've had everything set up since Saturday evening (I've hopefully crawled under my floorboards for the very last time), and here are my thoughts (sorry for the bullet points - I don't really like them, but it's just more efficient doing things this way):

Immediate Impressions

•   ultra, ultra-smooth
•   the whole sound-stage is now placed well behind the speakers
­   - cymbals generally waaay back in room (but still totally crystal clear)
­   - voices 1-2m behind speakers
•   perception of slightly compressed dynamics (compared to before)
•   nothing jumping out independently into room (in front of MF/HF horn), and absolutely nothing annoying – I could imagine listening at high SPLs to virtually anything, without any listening fatigue
•   loads of deep bass sounds good !... at long last!

On further listening

•   this is NOT a hazy, soft, woolly sound at all – there’s incredible detail
­   - easy to distinguish between different types of cymbals
­   - I'm hearing nuances I've never noticed before
•   beautiful balance to sound (maybe a little bottom-heavy, but this will be easy to adjust if I decide I want to)
•   double bass now resonates beautifully (maybe not quite as much as at Paul’s place with his Orelino speakers, but a quantum leap over the ‘paper-bass’ sound I've had with the Orelos up until now)
 
I'm really, really enjoying the sound I have right now (looking forward to the next listening session is always a good sign, and one that I've not had for a while). And more importantly, I'm totally, absolutely convinced the system is now more musically satisfying than before.

A MASSIVE thank you to Peter. Man, where would we be without you?

More to follow (I'm sure)...

Mani.

[Edit: My (second) NOS1a, which I'll refer to as '75 B' from here on in, has had the 'Nick/Paul mods' applied to it by Paul, namely; a bunch of Black Gate caps, and a Dexa USB clock with independent PS.

So USB cables is kind of uncharted territory for me ...

The only other USB cable I have is the
http://www.neo-w.com/english/d_usb-2.html
The "S" cable ..... Which I briefly experimented without much success, though it was well regarded in places like audio exotics.

I followed Mani's recommendation on iFi, and found their top of the line
USB http://ifi-audio.com/portfolio-view/micro-iusbpower/
http://ifi-audio.com/portfolio-view/accessory-ipurifier/
setup with the power dual cable and purifier
However having 4 components for USB did not make sense to me

Then I read up on the total dac USB cable
http://www.totaldac.com/USB_cable-eng.html

Now Joachim's/Boleary's recommendation seems most simple.
So .... Is there any issues with the DAC and server sync ? Any downsides otherwise for a data only cable?

Thanks in advance
VJ
