  1. I bought a very inexpensive, new in the box Pono music player recently. Made a balanced star-quad cable for my HD650s and found that it is a very nice player, but the combo of HD650 and Pono seems to lack a bit in bass and midrange, resulting in an overall too-bright a presentation. I'm already using HQPlayer convolver on the PC to apply EQ and cross-feed, so I came up with the "brilliant" idea of applying DSP impulse response files to music before transferring it over to Pono, hoping to hear a much more balanced output through the headphones. My question is, what's the best way to do this? I have Sox and used it to convolve files before. I assume just convolving the music file with the EQ impulse response file will be sufficient to get a better frequency response, this seems simple enough. The more complex question is how do I do this with the four impulse response files used for cross-feed by HQPlayer? My current setup looks like this in PC HQP: Am I correct that to apply the same processing manually, I would have to convolve the left and right channel music files with L-L.wav and R-L.wav (respectively) and then mix the resulting two files at 50% each to get left channel output? And then do the same with the right channel: convolve L-R.wav and R-R.wav with left/right channel audio, then mix at 50% to get the right channel output file? I'm going to test this, but was curious if anyone can confirm or deny that this is the correct process. Thanks for any help or insight, and happy holidays!
  2. Does anyone on this board have any experience/familiarity with Edifier’s products, especially their powered/active speakers? They appear to be attractive technologically and definitely price-wise. The company seems to have relatively recently entered the US market (via Amazon) and appears to be popular in Asia (based in China) and Europe. They seem to be well liked among posters on HeadFi. In addition the blogger Digital Stereophony http://digitalstereophony.blogspot.com/ has performed some interesting speaker comparisons where Edifier speakers came out well. Based on his recent test (vs. JBL LSR305, Klipsch R15 - PM) of Edifier’s S2000 Pro (incl. DAC/DSP) this seems like a serious performer for the price. Not reviewed is the lower priced S1000DB (w/o DAC). However, except for good reviews on Amazon I’m reluctant to take the plunge despite what otherwise seems to be the real deal. Other speakers in the running: Vanatoo T0 (w/a sub) & T1; Audioengine HD6; Peachtree M24; JBL LSR305; Klipsch R15-PM. Any insight would be appreciated.
  3. Let's assume cables can be proven beyond a reasonable doubt to sound different. Even in the unlikely event that we all would agree on that, what is the justification for using expensive cables, rather than digital signal processing (room correction, parametric equalization, etc.), whose properties can be readily controlled and whose results are easily measurable, to alter what the music sounds like?
  4. Is anyone been able to use the software version of Dirac with their Microrendu or similar DLNA network player? If so can you please describe your signal path. What software are you using, Jriver, HQPLayer, Roon etc.
  5. Hi Guys, here is the video guide about the Devialet SAM and how to. I actually I didn't know exactly how the "uncle" SAM is working but this is giving some very nice details and step by step explanation how to. Of course it's the short version but you can imagine the rest;)) Any thoughts on this topic?
  6. Hi everyone, after having invested in heavily appreciated "fanboy" gear like REGEN USB , CURIOUS CABLE and a KLEIN DAC (See more here) in my first year with the CA community, I have had a read here on the "biggest bangs for buck" threat, which convinced me, that doing something on the acoustic treatment of my listening room should be the next step before investing even more on hi-end equipment. Maybe investment on useful hardware like the minidsp UMIC or an antimode processor still does make sense, even a bass enhancement with a good sub could be adjusted to the plan. I have two B&W 805s in a "golden" triangle position with my armchair and with the speaker positioning I am quite happy so far (in detail dist. to sw 61cm dist. to rw 131cm, dist. to other Speaker 181cm, dist. to listening position 181cm (157cm from the straight line between the speaker). What needs to be improved - in my opinion- , is a noticeable hiss from the left with sharp high tones , i.e. the harp sound in "Postcard Blues" /Cowboy Junkies/Trinity Session or some of Jan Garbareks sax notes are sounding kind of unwelcome. Plus, even I had looked for a n symmetric and equilibrate approach to the room, I sometimes get the impression that the left speaker is more present than the right, could that be related to the different surface of the sidewalls ? And yes, having exchanged the speakers from left to right gives me the same phenomena. ;-) In addition my speaker have some limits in presenting the deep lows as their frequency response is 49Hz - 22kHz at +/- 3dB and the frequency range should be -6db at 42Hz and 50kHz. For starting this project on acoustic treatment , I'd like to ask: - Is it inevitable to commence with a measurement of the room nodes or are some first steps to improve rather obvious for some expert eyes? - Which would be the software of choice for the measurement ? - Does a Android app like "Audio Tool" on a Sony Z1 could do the job, first hand? My first ideas had been about having some canvas or molleton curtains for the last 150cm on the sidewalls, and maybe some absorber hanging from the ceiling, allowing me to reshape parts the ceiling in a more symmetric way, but only on the right side (WAF), as I would not like to cut too much the luminosity in the room. That said, would a linen drapery on the glass front of the window have some effect as well beside it translucent looks ? - Is there anything I could improve on the first reflection points ? I welcome your thoughts and inspiration on the subject Merci Tom
  7. Any suggestions of a good parametric equalizer DSP component for foobar for free? Looking for one that allows adding as many bands as I want, with different EQ curves options (high pass, low pass, high shelf, low shelf, peak), Q setting, etc. Thanks.
