NOS1 to the next level ?

[Gerard]

  Are you doing.....

 

Gerard hi,

Just the stuff I have always done with DACs but the results here are bigger than usual. I think it is a function of how well designed the NOS1 is. If you stumble on a slight bottle neck and address it lots "gets through". I'm very interested to see what Peter makes of the changes how they measure etc. I'm always a bit cautious of posting claimed improvements just in case they don’t work elsewhere.

Hope your enjoying the sunshine !

Ok that is some nice inside information enjoy the nice weather too. 

Hmmm he must get home from holiday now....

btw where on this planet are you Peter??

Have a chopper ordered. 


  Enjoy as much as you can!

Will take a  few now...

I must say that the timing for this vacation could have been better somewhat. I never have had such a great tool under my hands before (but have always been looking for it), and next to that Nick came along with his little surprise. I just had time to get it running before leaving, but after applying a couple of things upside down, inside out, plus to minus, I destroyed my great tool #1 and experienced ticks from it. But, still could get the merits Nick is talking about, well, sort of;
My great little To(ol)y had been playing for two days, and the combination with Nick's appliance urged me to do something quite else, and urged me to tell the world about *that*. But I guess it needs a little waiting, which I guess for me is worse than for you out there.

So, not one little gadget with great results, but a tool on top of it that makes it crazy all together.

But okay, my balkony where I'm typing this right now - looking over the east coast US ocean - a cigar here and a beer there - also is quite nice.
The upcoming week should be as crazy as again better music, real bad weather and tornado's crossing our path for 100% sure at going more northwards. Should be something else for a change !

I must say that the timing for this vacation could have been better somewhat. ...

My first boss never went on holiday, he was afraid that if he did when he returned his job would have disappeared... years later another one of my bosses went on holiday, he was in charge of the biggest department in the company, about 3000 people, when he returned his department had been disbanded and his last task was going on a tour to tell "his people" to find another job...

moral to the story, always holiday as if it was going to be your last one!

Hi all again,

Change no. 3 is now in the bag. Again it is quite simple, based on something I have done before this time inside the PC and also inspired by something that Peter mentioned in a PM.

The sound change is a significant one. Just when I thought that all the hash had gone, much more has disappeared, when will this stop ?  , I really don’t think there is much more left now. Sound changes centre on effortless macro and micro dynamics with improvements in instrument tone and levels of substance (again). Its all very "real" sounding and not at all forced. I am not quite sure about this but there could be a very, very slight loss in bass extension and high frequency response (compared to how changes 1 and 2 sound together). The three changes working together sound so right however that I am working on the theory that these small changes to the top and bottom end are just reflections of what is in recordings.

Altogether things are sounding pretty special now

As usual I will send the details over to Peter to look into and test.

Nick.

Nick - you are a tease.

Power supply and cables were touched on earlier in this thread. For what its worth I have tried NOS1 with special power cable (low inductance and low capacitance) on a dedicated mains spur itself wired with special cable. In the past with other equipment this has made a significant difference but with NOS1 I cannot detect any difference versus standard mains cable on a normal house ring. More work to be done to be sure but NOS does not seem to be sensitive to power cable type from what I have seen so far.

Nick - you are a tease.

Paul,

Sorry, actually some of the guesses are close to what is being changed, but I would rather Peter looks the changes over before saying anything too specific. Rest assured there is relatively easy headroom to be had which could be good news for NOS1 owners.

Regards,

Nick.

Just thinking what next sorry 

[Scroobius]

Nick - no problem at all you are doing it exactly the right way. Its good to have something to look forward to.

Thanks for this feedback Paul. This is exactly the intention of it all, or IOW it works (as intended). I don't do much with mains cables myself, so for me it was just theory.
Btw, this counts for everyone with the little "meters" inside. For the others there may be a difference with mains cables (capacitance impeded).

[Scroobius]

Hi Peter - I forgot to mention but I checked the volt meters in both cases i.e. with the standard cable on the main house ring versus dedicated hi spur wired back to the distribution box with very low inductance and capacitance cable.

My NOS1 voltmeter readings have been rock solid i.e. they are always the same when NOS is fired up and have been right from when I first installed it - always reading the same (when they settle down which is quite quickly) one reads -4mv the other +8mv and there is no difference whether on house ring or hifi spur.

Sorry again for the teaser, but another change post.

Change 5 is applied. It is a really very simple change indeed, just the removal of a few components but it is by some margin the most profound change so far. A game changer in its own right and can be applied on its own. It changes the whole presentation, bass to highs, the effect on bass is simply great, taught full and deep delivery.

Details are with Peter.

Nick.

ps I don't want to have these posts come across wrongly, it's great fun making these changes but its only possible to get these effects because they are applied to such a great starting point...the NOS1.

[PeterSt]

Hahaha. I didn't read about "Change 5" yet (will do that in a minute), but I can tell that Nick and I have been doing quite some sparring on "tweaks" to the NOS1. Funnily enough we both started around the same time on rather different physical subjects but with the exact same purpose in mind.

I think I am sort of finished with my part of the deal now, and Nick will soon be running out of appliances I guess. Then what ?
Then we both will have achieved the same but by very different means.

And then what ?
Then theoretically both can be combined as well. But, if either of us has done a great job, the one makes the other superfluous.

Well, now you know it all !

Peter,

Question: When you have it finished do we need to send the NOS1 back or wil it be something we can exchange ourselve?

 

[PeterSt]

I actually only today finished something which was key to it all. Took me 2 months or so. Ok, throughput, but still.

So, now I can start thinking about how to apply it.

Peter

[Gerard]

That sounds good!

 

[PeterSt]

How do you know ? haha
