mayhem13 Posted March 3, 2014 Share Posted March 3, 2014 Let's just say if there's a cause for a thread becoming an all out bitch fight, sandyk is usually involved. Quite frankly am rather tired of the fighting on these threads, just venting my aggravation towards you in a VERY controlled manner. Come to think of it, why am I even bothering to write or read here, when arguments stir around the vortex of a cesspool with no end in sight. This was an interesting place, one time. Goodbye CA. There's no way you're gonna let SandyK get the better of you.....or are you? Man up like the rest of us that have endured his nonsense. Link to comment
Superdad Posted March 3, 2014 Share Posted March 3, 2014 Goodbye CA. One and a half: I tried to send you a PM but it seems you have your profile blocked for those. Can you send me a message with your e-mail so I can send you the letter I composed for you? Thanks. UpTone Audio LLC Link to comment
Don Hills Posted March 3, 2014 Share Posted March 3, 2014 BTW, A higher level of Jitter can make a music file appear to sound a little louder, ... Distortion can have that effect. Our ears distort at high SPLs. Pre-distorting the sound fools us into thinking it's louder.

Paul R Posted March 3, 2014 Share Posted March 3, 2014 Yes. I wonder if Juan could measure with a meter, and if so, would that reliably tell us if it is an apparent loudness increase or a real one. I am intensly curious about that. I am 90% sure it is an apparent rather than actual increase, but I have been surprised before. -Paul Distortion can have that effect. Our ears distort at high SPLs.

sandyk Posted March 3, 2014 Share Posted March 3, 2014 Wow. You've gotten so outta control now that even your subjective bretheren are going to ground. I have been taking lessons from the master. You ! How a Digital Audio file sounds, or a Digital Video file looks, is governed to a large extent by the Power Supply area. All that Identical Checksums gives is the possibility of REGENERATING the file to close to that of the original file. PROFILE UPDATED 13-11-2020 Link to comment
Fokus Posted March 4, 2014 Share Posted March 4, 2014 Distortion can have that effect. Our ears distort at high SPLs. Pre-distorting the sound fools us into thinking it's louder. That's not the mechanism. Distortion brings spectral spreading, i.e. the generation of harmonic and inharmonic new signal components. These hit more critical bands in the cochlea than the original signal. More receptors fire => perception of higher loudness. Something with increased distortion with level works as an upwards dynamics expander. Link to comment
Fokus Posted March 4, 2014 Share Posted March 4, 2014 tell us if it is an apparent loudness increase or a real one. 'loudness' exists only in the perception of the listener, 'level' exists objectively in the outside world. Different signals of the exact-same level can give rise to different loudness.

Paul R Posted March 4, 2014 Share Posted March 4, 2014 Yes, you are right.. I knew there was something wrong with what I said, but missed exactly what it was. Level is exactly what I am interested in- did the actual level change? Thanks Fokus! -Paul 'loudness' exists only in the perception of the listener, 'level' exists objectively in the outside world.

roh008 Posted April 22, 2014 Share Posted April 22, 2014 Hi all, currently running a HTPC using JRiver My OS is Win 7 on a SSD MY music is on a separate HDD. Just wanting to check in at what point the above mentioned changes in SATA cables and HDD/SSD swaps have an impact on the data in the digital domain? I assume tests such as recording the analogue output of these changes has shown differences in the graph? Too many variables involved in a listening test where as capturing the output and overlaying the graphs will show what's changed. (Using the same DAC and same methods of course) I would have thought changes at the DAC stage would be critical and pretty much wipe out any potential changes in a digital domain. Assuming an out board DAC is used and connected via USB or SPDIF. Would i be right in saying set up in this order of importance: 1 speakers 2 room acoustics if possible (hard for me in a living room) 3 amps 4 DAC 5 FLAC/AIFF/WAV etc. 6 then start tweaking with HPTC or dedicated Music computer. Thanks Roh Link to comment
coxhaus Posted May 5, 2014 Author Share Posted May 5, 2014 Just to let anyone know who is going to buy ASUS SATA cables to buy the straight plug kind rather than the 90 degree turn type. I think it is a little better sounding. I don’t know for sure because I have made a lot of changes lately but I am running a straight version now. I will revisit the old 90 degree turn cable later after I settled into the new changes.
