OS X Audio Players: Amarra, Audirvana, Pure Music, Fidelia, Decibel, and BitPerfect
http://www.headfonia.com/os-x-audio-players-amarra-audirvana-pure-music-fidelia-decibel-and-bitperfect/

Sometime in 2011 I began thinking about the possibility of doing a review on high quality audio players for the Mac OS X operating system. Even though Windows users still represent a big part of Headfonia readers, I choose to focus on OS X for now because it’s easier to do as I use Mac myself, but also because for most developers, OS X seems to be the platform of choice when it comes to high quality audio playback.

AKG K550 — A New Closed Headphone Favorite
http://www.headphone.com/rightbetweenyourears/?p=2393

One of AKG’s CES 2012 releases is the K550 ($299), a full-size, closed headphone sensitive enough to be driven from a portable player with the tonal accuracy of the K701/702, but with fuller bass presence. Finally, a closed headphone that rivals the Denon AH-D2000 that looks and feels like it will withstand the rigors of portable use!


-----

The bass is tight and detailed as we’ve come to expect from AKG, but with a fullness that rivals the Denon D2000, only lacking the extreme sub-bass extension of the Denon. The mid-range presentation is lush, silky and cleaner than the thicker mids of the D2000, and while the highs are crisp and articulate, they never reach a point of harshness like the D2000 is prone to at higher volumes. We found the soundstage of the D2000 to be slightly more open and airy, but the K550’s imaging is excellent with good separation and definition, demolishing the sound of any other closed AKG headphone.

-----

The excitement is high for the AKG K550 here at HeadRoom. We’ve been long-time fans of the Denon AH-D2000 and the K550 gives it a serious run for the money, especially at $50 lower MAP. This is a great choice for someone looking for a tonally accurate headphone with a tight and full bass response, but doesn’t want the fuller, thicker presentation of the D2000.

Bricolaje (DIY) / DIY Shielded RCA Interconnect Cables
« en: Febrero 23, 2012, 14:30:02 »
Una opción para cables RCA: Instrument and microphone cable

Instrument and microphone cable must provide a very good shielding to block noise and radio frequencies (RF) and it is designed to deliver a wide frequency band. This makes a lot of sense as instrument cables are used with guitars, microphones and studio equipment. Why should this not work for interconnects? That was the quest(ion).

DIY Shielded RCA Interconnect Cables

This project is a guide to build your own simple high quality RCA interconnect cables for your Hi-Fi audio system. These "better DIY RCA interconnects" are unbalanced and made using shielded instrument cable and high quality RCA plugs.

DIY Modification for the Sennheiser HD 800: "The Anaxilus Mod"
http://www.innerfidelity.com/content/diy-modification-sennheiser-hd-800-anaxilus-mod

the stock HD 800 remains a tad hard on my ears, and many headphone enthusiasts have expressed similar sentiments. Over the years a tweak for the HD 800 has been developing in the enthusiast community at Head-Fi.

Adding artwork corrupts some Lossless iTunes files
http://reviews.cnet.com/8301-13727_7-57361159-263/adding-artwork-corrupts-some-lossless-itunes-files/

Apple's Lossless audio format is a popular option for people importing CDs into iTunes who wish to preserve as much of the original song quality as possible; however, a number of people have been noticing that random tracks imported in this format become corrupted after artwork is applied to them.

Del CES 2012: [nota: simplemente comparto el artículo sin entrar en el fondo del asunto ... ] 

Klipsch Group Sees Their Future In Apple’s Airplay [CES 2012]
http://www.cultofmac.com/139148/klipsch-group-sees-their-future-in-apples-airplay-ces-2012/

“We feel like Airplay is going to be the next media,” Product Manager Gavin Reeg said during Klipsch’s 30 minute press event. Then it was VP of Product Development Mark Casavant’s turn, and he made it very clear: their future is in Apple’s Airplay.

Klipsch is moving to support Airplay in many (if not all) of the Audio Systems they release in the next 9-12 months, and are also seriously considering adding support to other product lines they own, such as the Energy brand.
