Good analogy - the carpet in the case of S-D DACs is the measurement tool, the FFT.
DAC/Amps
AURALiC Vega DAC ($3499) and Taurus MkII ($1899)
Simaudio MOON Neo 430 HA ($4300 w/DAC)
HeadAmp GS-X Mk2 ($2800)
Schiit Ragnarok ($1699) and Yggdrasil ($2299)
Woo Audio WA-234 ($15,900)
Apex High Fi Audio (TTVJ) Teton ($5000)
Eddie Current Black Widow ($1248)
Violectric V281 ($2299)
KGSSSRE (Kevin Gilmore Solid State Special Reviewer's Edition E-Stat Amp ($Unobtanium)
Woah! Tyll will be the first professional reviewer to take on the Schitt Yggdrasil!

That should be a good read..
agreed that high end DACs are more about individual tastes but the review about Hugo is surprising as in last one year only this is the negative review of hugo i have read at least for sq and that too for the Treble for which it is most regarded amongst the high end dac.

OK, understood, you are correct on the numerous variables present and the very subjective ways we all interpret them. I have never had a treble problem with the 560, others find it very annoying.
My problem with the O2/ODAC is also subjective, tonality is critical to me, they just didn't sound natural with multiple headphones. Others love the Audeze "House Sound," I don't. While I love the 560 and HE6, many of those who like Audeze don't care for them.
What I try to do on Head Fi and in reading the Audio Literature is find those with similar tastes, biases, and objectives, then learn vicariously through their experiences.
the link between feedback errors and slewrate was the source for some controversy in JAES in the '70s when Matti Otala started publishing his theories on Transient Intermodulation Distortion - there are links depending on the amp electronics internal design, Otala incorrectly assumed a particular linkage was unavoidable and dogfights ensued his fundamental assumption has been shown wrong in theory, by hardware realizations, custom built measurement hardware using his TIM definitions - but it is a powerful meme that many wanting to criticize high feedback amplifiers have refused to give up
another thing that has happened without getting credit from Otala/TIM adherents is that over time op amp manufacturers have improved the semiconductor processes and internal circuit topologies - modern chips intelligently selected for the application have vanishingly small slew rate caused errors for audio
and that's off a "baseline" of NE5534, TL072 that managed ~ 10 V/us in the '80s
just take a "prosumer" $150 sound card like the ESI Juli@ and try to show TIM in analog loopback - despite the only slightly better than generic op amps - certainly not using anything a "op amp roller"would put in, "audiophile" manufacturer would brag on (if they admitted to using op amps at all)
interpreting fft bins does require knowing record length in addition to sample rate because frequency is inherently a distributed in time concept
but that really isn't "extra" knowledge - count the bins and look at the frequency axis labels - no different from getting time domain record length form sample rate and number of points
