Just rip a CD you own, using something EAC with full paranoia options on and compare...the .wav wins in my system, every time, little doubt, double blind test.
a 'passive pre-amplifier', or rather a (shunt) resistor between DAC and AMP works fine. I can recommend Khozmo as one of the most neutral versions I've heard (and used with Z foil resistors).
The sonic difference between digital volume control and real colume control is quite real IME, Metrum...
I'd say that taking the Koenigsegg to Munich High End over the German Autobahn would be best of both worlds...one would need a dash of tranquilizers upon arrival in order to aprreciate sound I guess..
That is the beauty of designing your own speaker, one can adapt and try things...
The Bionor does not really have a tweeter in it's original design, 500Hz and upwards are taken care of by the top horn (or horns for the Bionor II)
It IS adjustable, I agree it's not likely tuned in the horizontal...
Theoretically they are Kugelwellenhorns, patented for having a large phase coherent 'plug'
A calculated phase coherent speaker IMHO always sounds worse than a speaker that is physically time adjusted..call me silly but that is my preference and that of many who have heard the difference so far...
more so than most of what I heard at High End Munich last year...
I'll go for the setup I tested in my prototype, full range and a super tweeter rather than the 500Hz higher order crossover the horn.
the mind is indeed building a similar picture (I'd not call what I perceive ina concert hall as hologram at all), yet the way different systems do that is differing...and for me some ways work better than others, for others it'll be the other way around. I find phase/time coherence to be of...
