The problem with subjective impressions

But apparently one DAC manufacturer has designed an in-built system which compensates for component ageing:

I would hope there are no electrolytic caps in any critical signal path/voltage reference. This is more for resistors and usually voltage references and analogue signal paths, where hopefully very stable caps have been used such as COG often with a 0.1% drift over life. Thermal control of sections of circuits avoids thermal drift and is used quite a lot for designs going into areas of temperature extremes, ADC's in space... And more mundane circuitry such as monitoring kit where its going to be cold... Keeping electronics warm in a cold environment is often easier than keeping it cool in a hot one, heat is not good for electronics.

One power supply manufacturer I know pre-age certain resistors in critical to avoid ageing drift over the life of the unit... The output is 30kV +/-0.2V though over the entire life of the supply...

The forum also provides an option to exercise if you have reason to believe that an Ignored User may have posted something of interest or value. IMO and experience, such instances are few and far between.

I get the impression from these sort of comment on this thread and similar comments on other threads by others, that the hardcore subjective fraternity won't be happy until I and certain other members are banned and every thread is censored and cleansed of any comments they don't like. The forum has already been stifled by recent events and there are specific threads to discuss this, instead of every thread getting polluted by this negativity. What was an interesting forum full of lively debate has turned into a rather dull place, where the only conversations allowed are approved ones.

Your interpretation of my post does not at all reflect my intention or beliefs. I have no interest in banning people. That power is Chris' alone. exercised when he believes a member has egregiously breached the rules of the forum. As for "censorship", my post was simply a reminder that individual members can hide the posts of those users who they find to be offensive, of no value, or both. I do not advocate the general "cleaning of any comments they don't like" from any forum. Having said that, I reserve the right, as does every member, to attempt to avoid being subjected to what I consider to be the pollution spewed by certain members. It has nothing to do with disagreeing with a philosophical point of view, as evidenced by the fact that you are not one of the very view members on my Ignore List.

Sorry I used your post to make my point, on reflection another post, on another thread (Que Sam, Play it once, would probably been better for my mini rant...😀

Debate doesn’t interest me in the least. I get more than enough in my day job. 🙂

 

What this place used to be full of years ago was a bunch of people trying to *help* each other as we all learned a little more about computer/digital audio. Learning more is what interests me.

 

It’s easily possible to be helpful and informative without debating.

Still is, just no reference to physics, electronics, engineering or perception allowed, pure belief only, even the faintest sniff of technical intrusion is often met with discord, such as a recent thread on master clocks where relevant technical intrusions were shot down before they even began.

The discord arises from people who don't understand physics, don't understand cognitive psychology, and/or think that one or a small number of measurements fully explain SQ.

 

I think that covers all the bases...

That's why I think open discussion is important to sort the facts from the fiction, what is important, what has the most effect... Input from all sides...

I was just thinking about this a bit more. Perhaps the reason so many of us like to upgrade or make changes is because of the power of music. We want something more and are willing to try things, sometimes non-sensical things, to get there. And, the journey can be fun. 

 

I know it sounds a bit like chasing the dragon, but this is completely voluntary and enjoyable for so may of us. 

Or pick up an instrument and really start getting into music...  Since I started playing the Bass again my musical horizon has widened to extremes that before I would not have considered and as my education and ear improves, its interesting to hear the same sequences in many forms of music. I tend to listen more technical in a way, but still get caught up in the emotion, more so if I'm playing along and nail it, the tears can flow and emotions run high.

I’m assuming the bi-peds screwed up and therefore don’t really deserve a reprise. In the grand scheme of things I don’t think nature cares about who ate who. Octopus intelligence has evolved along completely different lines from humans and it seems only fair they should be given a shot to evolve their equivalent of language and writing systems (squid ink based?) and whatnot. 

Who need ink when your body is a monitor...
