I would welcome pointers to either.
Hi all, I'm here just becouse Julf named me as the one opened the THD, but - as you could read in the original thd - I was the first asking not to open this can of worm , again... I feel quite stupid about that, but it resulted that the bug I was reporting was already soved and I was running an old version of the software...Something went wrong at some point this summer and I did non double ceck... Sorry to waste my and Michael time for this. But at the end of the day, this means LMS is still supporting WAV, AIF and PCM streaming and this is a very good news for me. As a note, I want to report that I was impressed (in a very negative way) by the 'hate' some people has put in the world 'audiophile' being a sufficient reason itself for reject the question and relegate it to this 'ghetto'. I was wrong (an stupid) because I was usingan old version, but I was right in the matter,it's so thrue that was already solved! Hope someone else have a similar tought about mocking everythink 'sounds like' being audiophile... As a note, all the 'rumor' in the THD, for sure contributed to make the waste even bigger. Again, sorry for this. About the matter of this thread, I'm not really interested, is one of those things that one has to try by itself in his own system. Aftre reding the Archimago article, it's clear (and is not nothing) that differences are little but are in place, "-90db means are inaudible" is wrong, it depends on many factors. But here I think other than IT guys have to join the discussion. Discerne if rumors come from CPU, memory, ethernet or what else is not in my competence field, so I don't ever want to debate this. Measure by two different systems shows CPU usage Is increasing using flac vs WAV, net traffic is - of course - decreasing by a greater factor (see the original THD for details), but sure, those measure are too naif. I'm still missing the one that prouf the opposite and - in any case- I think they are not 'the answer' to the question. ____________________________________________________________ SB+, Klimo Merlino + Kent Gold, Monitor Audio Studio 20 Gold SE+, Klimo reference and DIS Interconnect. ------------------------------------------------------------------------ marcoc1712's Profile: http://forums.slimdevices.com/member.php?userid=34842 View this thread: http://forums.slimdevices.com/showthread.php?t=104227 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
