Not sure what prompted such an unpleasant reply. As far as incorrect/incomplete testing procedures, I am fully aware of the concept of double blind testing. Additionally, I should add that as an otolaryngologist (ENT surgeon) at a large academic center, I have been involved in setting up and running large clinical trials costing several million dollars and involving several thousand patients/controls so kindly do not presume to lecture me on expectation bias, etc. as you do below. As a result of that understanding, I am also fully aware that my procedures above do not constitute a randomized, DBT but they do consitute a simple way of delineating any major differences between the Transporter and SB3 in the comfort of one's own home. iPhone;409297 Wrote: > First, common sense should tell you that you are wasting your time as > well as ours because the DAC chip, DAC circuits, power supplies, and > analog output section in the Transporter are superior to the SB3 in > every department! That's great. I'm well aware of this fact and of the fact that there are several measureable improvements in SNR and other engineering parameters. That does not automatically mean an improvement in sound quality. For someone who spouts "pseudoscience", you fail to realize that anyone with a robust scientific background would approach the comparison between Transporter and SB3 with an understanding that the null hypothesis (ie that there is no difference in sound quality between Tp vs. SB3 regardless of all the engineering hype) is the starting point and one must gather evidence to prove that the alternative hypothesis (ie that there is a difference) is correct and not vice versa. If I'm wasting your time, feel free to read another thread and do not presume to speak for others. iPhone;409297 Wrote: > Second, your ears can't be trusted as they are connected to you brain > that uses all available information at its disposal to make > conclusions.

I should keep that in mind before I go and perform that cochlear implant tomorrow morning. What "actual facts" were your audio engineer friend and yourself testing? The "actual fact" that the TP sounds better than the SB3 or various technical measurements that may/may not correlate with audible improvement? You speak of using software to eliminate the bias inherent in ones "brain, eyes, and ears" but we are talking about an audio device here--as in something purchased to LISTEN to music. Any comparison beyond audible differences is completely moot. What do I care if an oscilloscope demonstrates measurable differences between a TP and and SB3 if I can't hear those differences? iPhone;409297 Wrote: > Third, if you don't already know that XLR Balanced outputs are superior > to RCA outs, then don't bother wasting your time and ours. Nowhere in my OP do I ask or suggest that XLR balanced outputs are superior/inferior/equal to RCA outs. I was simply asking if using the XLR outputs influences the volume. iPhone;409297 Wrote: > The SB3 has a 6.0Vpp RCA line level output and the Transporter XLR is > 8.5Vpp so it had better sound louder into the same pre-amp line level > input!

Again the ears are misleading the conclusions and the brain > is making assumptions. Which is precisely why I posted immediately after P. Farrell's wonderful suggestion regarding the fact that I volume leveled the SB3 and TP using a Radio Shack sound level meter. As far as misleading conclusions, my ears are all I care about in this particular comparison since, again, I plan on using the TP to listen to music rather than gather audio engineer friends and break out the oscilloscopes to start measuring. In conclusion, I believe the original post was a valid question about my experiences A/B'ing the TP and SB3. I was simply asking questions to refine my testing so that I could assess the two devices. Thus far, the majority of comments with the exception of yours seem to have offered decent advice so I'm clearly not wasting everyone's time. Thank you for your time regardless. -- El Duderino ------------------------------------------------------------------------ El Duderino's Profile: http://forums.slimdevices.com/member.php?userid=8171 View this thread: http://forums.slimdevices.com/showthread.php?t=61686 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
