PS: There is something else I noticed yesterday which could even be more strange, and tonight I am going to check that for its merits (better). If I can confirm what I noticed already, I will open a new topic for that tomorrow.
If you search for "Machine Head" you will find a few posts from me about the "stuffed ear" lacking highs on that album.
And now this has suddenly changed ...
I was playing a track from Animals (Pink Foyd) and that too has miserably failed for the highs. Maybe with the exception of one remaster of it I found the other day (I think I put that to the forum as well) but still far from on par. Thus, day before yesterday I played that track, checked whether it was from the original mastering (it was) and thought that something must have changed somewhere regarding the highs output. This readily made me look for the Machine Head album which is always THE example of way way lacking highs and such a shame (because an album from my really younger years).
Into the second track I seemed to be sure ... where are those lacking highs now ?
Then dinner was ready and I had to stop.
So I played it again yesterday and I have been wondering for 40 minutes in a row how this can be. The album sounds the best "on par" as can be, and beyond.
It is also the best version I heard ever and I can really talk about "beautiful". I actually never heard a thing of what's on it, as it now appears.
If you search for "stuffed ear", you also find a couple of posts from me and a few of them are from lately (2016). This is because I start to notice that albums can quite explicitly exhibit the stuffed ear encouraging feeling and this happens with albums which did not exhibit that before
Of course, we can envision what all can happen (without really understanding it) to cause such a thing. But in the very same physical setup/environment it now also works the other way around.
So the one album exhibits a roll off suddenly and the other has completely removed its even super huge roll off.
I don't get it.
Maybe people have hints for what to look into or try. Maybe people have failing examples themselves which I could try over here and possibly we are able to reason out what is happening. Mind you, the failing as such can also be at the other end of the spectrum : way too lean and too much highs. Regarding this, the example of Year of The Cat which only until just over a year was way to lean for me (from computer playback). But listen to it now - all in perfect balance and unbelievable lows. So yes, that too adds to the strangeness - the one album receives way more of the lower frequencies (which should kill the highs, theoretically) while in the same setup a next album lifts the highs like crazy.
For the crucial components, this is what I use :
- Stealth PC with linear power supply, 2640v4, 14393.0.
- Self constructed USB isolator (yeah, you guessed that - wait for yours);
- Clairixa USB (2x);
- XXHighEnd 2.06b, SFS=0.12, Q3,4,5 = 1,1,1. Clockres=1, Driver Buffer 4ms.
- Custom filtering - High-2nd, 705600.
- B'ASS buffer/amplifier;
- Blaxius Interlink (2x);
- And a set of amps/speakers of which I'm quite sure it won't matter for this "issue".
The least this post/topic can do is serve as reference for later.
