ISO Regen performance Improvement Cheap!

Yes, while we are talking about the purely digital areas, and we have established that there is zero spillover into any analogue areas, by any path whatsoever, to a degree that has audible impact on SQ - then there should no problem.

 

 

ok, so we isolate, re-clock, use Big Buffers (the subject of a song by Sir Mix-A-Lot)*

 

and then we need to be very careful with the DAC and with the amplification chain.

 

That will accurately reproduce all the crummy masterings we have (and the few great ones too)...

 

...until we get to the speakers & room.

 

Those are the problems as I see it.

 

 

* which are the things the iso-regen focuses on, does it not?

 There is ALWAYS some spill over in a real world computer from the Digital to the Analogue areas via the Power Supply.

 Check out the specifications of some recent HDDs and they even list the level and spectrum of the very high frequency  " square " wave pulses going back into the power supply area.

In case you haven't noticed, this is a Subjective thread, and your continuing insulting remarks have no place in this thread, OR any other thread for that matter.

Yes, yes, yes.
This poster very 1st put on ignore list, because violated all 3 ignore criteria (fools, villains, time-wasters). Now seems worse.

Ignore feature is good, but still see Quoted stupidity & vileness & too many "You've chosen to ignore content by Ralf11" littering threads & Activity lists like under seagull flock perch. So many garbage posts now start to stink ?

 

Maybe someone complain to management of continuing pattern of abuse behavior ruining CA experience?

If the OP hasn't specified, then it is not so limited.  Now did you read item #2?  

 

here is a helpful hint: item #2 is a Subjective item.

 

I feel sorry for the ostrich who posted above, and hopes he finds his snowflakes.

 I would expect that others have already done this, and that Admin will be well aware of the continuing disruptive behaviour .

This is where my experiences differ from most - I took, and still do, the highest level of care with getting the electrical path to be of maximum integrity, in every area. And the reason for that is that if one takes it far enough, then something, yes, 'magical' happens - the ear/brain takes over and decodes the "inner meaning" of the recording - and the speakers and room become completely irrelevant, to the subjective experience.

 

 

Just adding all the good bits, like the iso-regen, may, or may not, tip the rig over into this optimum zone - there are no guarantees, because every setup has a unique set of "issues" - as the the letters say, YMMV ... .

yes we differ on that - I rely on competent engineers to take care of that

 

I did post a thread where I had the elec. utility analyze for noise on the incoming power lines, but they didn't find much so I decided against buying a Topaz (at least for now).  I've already eliminated gnd. loops.

 

I favor WiFi or optical based galv. isolation (and my computer (iMac) is far away from the DAC both in terms of electrical circuits and simple RFI type distance)...  seems to be enough (for now).

OK, this is just a case of getting some engineering into the situation - either buy components where this is sorted, or get someone in to work out solutions for one, or DIY. There will always be a way of making it all work as it should - the trouble at the moment is that one can't just look up a well known checklist, to make sure all is in order.

The engineers are competent - they do the job they're assigned, which is to ensure that the product meets certain specs - the issue is that they don't know what other performance targets need to be met, because there is no agreement on "what matters".

 

One just has to read interviews with the designers of, usually expensive, gear which has got a big thumbs up from fussy listeners - they "get the specs right" ... and then they start tweaking, without really understanding why it should make such a difference. And so end up sometimes injecting wads of BS into the promotional material, to 'cover' that they don't know what's going on ...

Been checking here for several weeks now and I am really surprised no one has commented on the single most bang for buck upgrade you can add to your system when using the ISO Regen.

In fact I think it would be a perfect add on that should be offered with all ISO Regens at point of sale.

 

If anyone has followed Rob over at US Audio Mart (seen you there often Alex) you will be aware of the discussions on the serious uplift in sound quality you get with just adding about $10 of cable between the power supply and the IR.

Its basically a quick and easy cable snap in and then just sit back and be blown away by the greater separation, low frequency dynamics and overall amazing depth to the music never heard before, i listen to Red Book files...its all there!

 

For those looking for an explanation on how adding cheap cables into the power in on the IR could make such a difference I have to say this has me dumbfounded and I was a complete skeptic, the low cost and easy install was the only reason i tried it.

 

Its basically adding a CAT7 cable with passive POE ends to carry the DC between power supply and the IR, when you connect up the 2 pieces just stick the power supply in the female jack on one end and stick the male jack on the other end into the IR and sit back and be amazed.

 

Some links below:

I don't see anything in the text you quoted saying that only subjective responses are welcome in this thread.

Haven't you anything better to do than try and make this thread unwieldy with more off topic rubbish ?

 If you have something on topic to post in this thread please do.

 

 If Chris receives too many more reports of deliberate disruption of threads by either side of the "Great Divide"  he may take some action that none of will like !

[Ralf11]

to be fair, it does present a subjective experience* even while not explicitly stating any exclusions

 

Now, let me see... according to the Code of Forum Regulations (C.F.R.) .... well, dang it!  there is no explicit CRR on this???

 

What does that mean?  Perhaps we should have a rousing discussion of what should be the de jure rule on a thread faced with this situation?

 

 

and presumably, since the OP was "blown away" (perhaps by not using a decent fuse while instead substituting an "audiophile" fuse based on the groovey subjective listening experience they provide) he is dead n' gone so cannot now inform us as to his Original Intent

Alex, my HDD are about a few hundred feet from my DAC (thank god for the day job) separated by fiberoptic cable. The fridge in my kitchen is more likely to “inject” noise than my HDD. Oh I’ve got a couple hundred pounds of iron & copper windings to smooth out the AC power to my audio area. 

 

So no, there isn’t always spillage. In my case by design. 

 

Now Im trying to hear some of the tweaks, and frankly wondering if my hearing isn’t so good, because I just don’t hear some of the tweaks that other folks find make such a dramatic difference ??‍♂️ That said I’m happy listening

 But yours isn't a typical computer, is it ?

 Have you also found the same improvement with Video via this route? 

I like to see some of the musical performances from SNL as well, when I can find some .ts streams.

 

Which tweaks are you investigating ?

 

 P.S.
 I just found the attached about HDD noise that I mentioned previously.

My computer equipment is all off the shelf.

 

My audio system is behind combo Topaz/Equitech isolator/balanced with LPS supplies to components. Solid balanced cables but nothing fancy.

 

i can hear the ISO Regen with the iFi Micro BL but have a harder time with the non BL iFi Micro. (upsampled to DSD512). 

The Phasure NOS1a/G3 is terrific — I appreciate the upgrade but can’t hear many of the tweaks in XXHE

 

AC cables don’t not seem to make a difference but I don’t spend months comparing.

The rules of thumb are, if your rig is fully in the good zone then adding extra tweaks doesn't gain you much - the Wow! factor is fully in place, and you're quite content; if not in the good zone then you will have to find the right tweak or tweaks that are most useful for correcting whatever is holding the SQ back - put on your best deerstalker, here; if right on the edge of the good and not so good, then just about anything you try will matter - changing the colour of the power cord might do the trick, .
