Geek Pulse Indiegogo DAC outperforms its goal - by Hi-Reality.
I took a screenshot after one hour of desperate try to place an order for a Geek Pulse S f (there is a picture below). The issue was to get my Paypal updated and linked to my bank account which would earliest happen after 2 days, anyways, painful it was.

Geek Pulse Indiegogo DAC outperforms its $38,000 Goal to $1,174,075! (more…)

In Post-CD Era, Will Hi-Res Audio (HRA) Deliver Full Sonic Reality?

High Resolution Audio (HRA)Will Hi-Res Audio (HRA) be able to deliver full sonic reality? (exceed the Analog tape?) Is 384kHz/32bit sampling rate enough to deliver sonic reality? or maybe much higher sample rates are required? Maybe (and most likely) the entire recording to playback process must evolve?

In any case, one thing is very clear now: HRA, now officially coined by CES as acronym for Hi-Res Audio, is a significant step forward. Why? because:

  • It is higher than CD-quality
  • It is more convenient and flexible to use than CDs
  • and, incremental improvements in audio recording and playback are now possible in much faster rate than ever before which is great news for everyone

When I visited The High-End Show in Newport Beach I clearly saw the paradigm shift: the change of Source and format in audio playback. Majority of exhibitors don’t use CD anymore!! What?! Don’t Audiophiles run CDs anymore? Well, because they now run Hi-Res Audio files from their MacBooks  and change the songs on their audiophile-grade source players via their iPhones and iPads. Thus, a paradigm shift from CD to Hi-Res Audio file.

I think the Post-CD paradigm shift is now officially announced when industry heavy-wights like Sony launch Hi-Rez downloads & playback (see Stereophile). Or, when the Consumer Electronics Association, CES, announces ‘Expanded Support of High-Resolution Audio” (see CES press release). I read today via Audio stream and NPR that Analog tape recording still was superior even to DSD and high-resolution digital (better than CD). So the performance benchmark of Hi-Res Audio (HRA) should be to exceed the Analog tape recording in terms of Hi-Res quality and sonic Realism.

The rise of Hi-Res Audio should be great news for everyone: the goal is, ultimately, to experience full sonic reality whenever we want it. With other words: being totally unable to audibly distinguish between perceived sound in reality and its perceived reproduction (whether it is an e.g. offline playback or a live broadcast).

What qualities matter when buying headphones?

Grado_SR60i_headphonesI have previously published a post on “What qualities and parameters matter when searching for and buying the right home audio speakers?“. How about what qualities and parameters that matter when searching for and buying the right headphones? This should be be highly interesting for many buyers considering market indications that the audio industry has seen a tremendous growth of headphones sales over the past few years (most probably due to the less expensive way to achieve better sound experience for personal use and the march of portable electronics e.g. iPods and smartphones). I have modified (Sound quality unchanged) my equivalent list for speakers to answer this question: What qualities and parameters are important when searching for and buying the right headphones? Here is the list:

  • Sound quality (Acoustic characteristics)
    • Bass (deep, punchy, fast, accurate, extension, control)
      • Well control and extremely accurate lead to a perception of deeper bass than there might actually be)
    • Midrange (space and detail: e.g. vocal, piano sound)
    • Tweeter (High end, hights): crystal clear, detail, smooth, polished, off axis performance (e.g. where frequency response does not drop off nearly as rapidly as with other bookshelf models).
    • Imaging (precise), Spatial (spaciousness), holographic
    • Soundstaging (uncompressed, three dimensionality)
    • Timbral accuracy (good, bad, etc.) (e.g. piano sounding real)
    • Details
    • Clear & transparent
    • Disappear in the room
    • Dynamic: play loud without distortion, loosing
    • revealing of recording material quality/character
    • Tonal balance: (Neutral, not warm but also not cool, sounds like the frequency response from top to bottom is quite linear)
    • Tonal integration (mids and tops transition unnoticeable)
    • Minimum coloration: honest sound, realistic reproduction from the sonic & music point of view, boxy coloration
    • Engaging (long listening)
  • Environment sensitive/demanding (indoor / outdoor use)
  • System sensitive/demanding
  • Design and finish
  • Build quality
  • Features (e.g. Active Noise Control, ANC, etc.)
  • Improvement/tweaking possibility (e.g. replacing the ear cushions, etc.) 
  • Comfort (long listening without ears getting hurt)
  • Price (value for money)

Write a comment and say what you think about this list, does it lack any parameter / factor, should it be modified in any way, etc.

 

What qualities matter for audio speakers?

Have you ever wondered which qualities and parameters you should check when searching for and buying the right home audio loudspeakers? I spent the whole 2010 doing research for finding the best possible speakers in the market that matched my budget; I eventually found the best pair of speakers (not to mention I also ended up buying four set of different speaker brands, testing them with my system at our home, and returning them!). In the meantime, I developed a list and a structure of parameters and factors to help me in my selection. Here is the list:

  • Sound quality (Acoustic characteristics)
    • Bass (deep, punchy, fast, accurate, extension, control)
      • Well control and extremely accurate lead to a perception of deeper bass than there might actually be)
    • Midrange (space and detail: e.g. vocal, piano sound)
    • Tweeter (High end, hights): crystal clear, detail, smooth, polished, off axis performance (e.g. where frequency response does not drop off nearly as rapidly as with other bookshelf models).
    • Imaging (precise), Spatial (spaciousness), holographic
    • Soundstaging (uncompressed, three dimensionality)
    • Timbral accuracy (good, bad, etc.) (e.g. piano sounding real)
    • Details
    • Clear & transparent
    • Disappear in the room
    • Dynamic: play loud without distortion, loosing
    • revealing of recording material quality/character
    • Tonal balance: (Neutral, not warm but also not cool, sounds like the frequency response from top to bottom is quite linear)
    • Tonal integration (mids and tops transition unnoticeable)
    • Minimum coloration: honest sound, realistic reproduction from the sonic & music point of view, boxy coloration
    • Engaging (long listening)
  • Placement sensitive
  • System demanding
  • Design and finish
  • Build quality
  • Features
  • Expansion possibility (for developing into a home theater system)
  • Price (value for money)
