Interesante documento sobre la impedancia de los auricualres, la resistencia de salida de los amplificadores y sus efectos sobre el sonido ...

Para los ejemplos utiliza los HD800, SR60 etc ...

Headphone amplifier output resistance ... an explanation (PDF, 128KB)
http://download1074.mediafire.com/nxciugln10ig/ms4k8wuqt18x8s3/resistance+and+impedance...+an+explanation.pdf

Besides the obvious drop in total sound pressure levels (see page 4), some headphones will also give a different sound
signature (frequency response) when used on amplifiers with different impedances even if otherwise similar.
Mostly in the bass department which can 'mask' higher frequencies and thus seem to affect the mids and highs too.
All dependent of the output resistance of the amplifier and impedance characteristics of headphone in question.

El nuevo Blu Ray BDP-S370 de SONY podría ser una opción económica (135€) para reproducir SACD pero ...

http://telefonica.net/web2/tiomiguel69/audio/BDP-S360/BDP-S360.htm

"La sección de audio es confiada a un DAC WOLFSON WM8524, un chip recién salido al mercado (principios de 2010), pero claramente orientado a la reducción de componentes, ya que obtiene los 2V de salida él mismo, con apenas tres condensadores más. Aunque se agradece que se incorpore un chip de ultima generación, y parezca no comprometer la calidad de audio , esperaba aquí algo más refinado, teniendo en cuenta que SONY ofrece soporte para SACD en este modelo, y el DAC que lleva no decodifica DSD. Por tanto, entiendo que el formato DSD se convierte a PCM antes de entrar en el DAC, y eso va contra la filosofía del SACD.
"

This only rarely happened, and most of the Down Beat albums have become true classics revered by all music lovers. These new editions present the complete original 5-star albums, which are often expanded to include interesting bonus albums or bonus tracks by the same artists at the peak of their talents. This collection presents true milestones of jazz history made by the most celebrated musicians of the genre.

Oculto por la carcasa algunos calibres tienen un conector para salida de datos ...   :P

Interfacing with Digital Calipers

Caliper Data Output:

   1. Pinouts
   2. 24-bit Data
   3. BCD Data

Besides the LCD display, many calipers have a digital output port for their data. Name-brand calipers charge significantly more money for the inclusion of a data port, even though they often build it into all of their models, only to be hidden by the plastic case.

Data Density Eats Tweaks for Breakfast

" ... if a journalist were to ask him what would be the most decisive factor in the future of high-performance audio from here on out, I think he would unhesitatingly answer, "The fact that iTunes handles 24-bit/96kHz audio."
