Well, my XPA-2 Gen 1 has an amp gain of 32dB, which, clearly, isn't between 27dB and 29dB so are you trying to suggest Emotiva engineers didn't know what they were doing?  I think all their current amp lines have 29dB gain. I believe they had made some 32dB gain amps for the entry-level novice market to accommodate less-than-capable receivers used as Pre-pros that did not supply the required voltage to outboard amps. This was likely an intentional and strategic move. I use an IPS-1 which has 27dB gain. I think the XPR series may have been at 29dBs or adjustable (not sure). So they had made a mix of products to suit their market. The XPA-2 Gen 1, XPA-3 Gen 1, and XPA-5 Gen 1, all are 32dB gain. They weren't made for the entry-level novice market IMO despite that their pricing could easily get a novice to wrongfully assume they were... and, 3dB additional amp gain is giving me 3dB additional headroom with regards to the slight background noise in the preamp section of my UMC-200 (inaudible in my setup, but not inaudible after I turn the volume up so high that I would need to wear my Westone CIEMs for ear protection whilst music would be playing through my Canton speakers, which would kind of defeat the purpose of those speakers anyway... albeit I actually tried that once, and it did work surprisingly very well in fact...  ) despite the output voltage of my current DAC is 2.8V in solid state output mode, and 3.2V in tube output mode so not too shabby IMO. |

Our inner reference does lie, and double-blind listening tests can reliably constitute this fact. Only problem, double-blind listening tests can also constitute, also reliably, this "other" fact that those who claim that we know everything there is to know about how the human auditory system works are those who are telling the bigger lie. "constitute:" to compose, form Yes - double blind tests DO compose "facts" but their veracity is profoundly lacking. |

It depends on how you prefer to look at things I guess. plato.stanford.edu/entries/facts...or, www.theguardian.com/film/2014/sep/07/werner-herzog-facts-do-not-constitute-truth |

Go to metaphysics if you can't argue convincingly from common sense. I've heard my wife's voice. Give me two recorded playbacks of that voice & I can tell which (to my ears) sounds most like her. That simple - done.

I will only tell this, in my 35 years of audiophile journey, every time I focus on sounds, imaging, precision and details, I lost the pleasure of listening music and as soon as I finish my comparative or sound check I rapidly return to the pleasure of music. I know that sometimes it is necessary to tweak the system but I realized that in the past I wasted to much time to listen sounds instead of music.
