    Reply to review by 'DGCFAD' on item 'Manley Laboratories Absolute Headphone Amplifier'

    It's amazing how much difference electronics can make. I was reviewing a $150 headphone the other day and just for giggles put it on the Manley with the R2R-1 and was totally blown away with how good it sounded.

    Review by 'DGCFAD' on item 'Manley Laboratories Absolute Headphone Amplifier'

    To fully understand why the MANLEY Absolute Headphone Amplifier is such a great deal, you must first understand MANLEY’s pedigree. Back in the late nineteen eighties, MANLEY began life as the Lexus to VTL’s (Vacuum Tube Logic) Toyota. That is to say that MANLEY began as David Manley’s rare air...

    A very simple way to accomplish what you want is to organize your files by artist then album (the player supports multiple folder depth) and use the "browse files" rather than the "play by category".

    Not to get into a debate, but the note I refer to is a conga drum and not electronic as can be clearly seen in the video. I don't believe the effect I heard was due to room acoustics, but the subsonic reinforcement inherent in a loudspeaker system as opposed to headphones. On the other hand you...

    The QP1R does support M3U8 playlists, but you will probably have to edit them for the correct drive names (assuming that you are using the same SD cards). I don't mess with tagging so I can't answer that question.

    Bruce is the North American office of the company, but American Sound handles all distribution for Canada and that would include service.

    The driver software is the same for both units, but you are correct the Mac doesn't need or use the driver software.

    Review: Questyle Audio QP1R - With Multiple Headphone and IEM Pairings

    I don't understand why you don't get that distributors are not able to operate outside of their region. You should be taking your issues to your local distributor or dealer, rather than haranguing the North American office for only serving North America.  But of course you bought your product...

    It is probably a nick in the black paint on the back side of the glass (dust under the glass would not be visible in that spot). If it really bothers you, you could contact Questyle and find out how much it costs to replace the glass.

    Review: Questyle Audio QP1R - With Multiple Headphone and IEM Pairings

    This has been answered, but for clarity, you have 3 protectors, it looks like you were sent extras in case there was a problem installing. The one without the tabs may not work. They are self explanatory but you remove the film attached to the step 1 tab, then stick that side onto the wheel...

    The QP1 had a very limited run (the QP1R actually came out first), you would need to contact Questyle to find out if there are any left available. In the US that is info_usa@questyleaudio.com

    They say they optimized battery usage, but I don't know if that refers to the indicator or actual operations.

    The transparent plastic disc provided by Questyle seems to take care of any slipping issues and it is not visible once applied.

    Impedance should be the same as that part has not been changed, efficiency (sensitivity) should have increased, but tuning change may cancel that out.

    MrSpeakers ETHER Flow and ETHER C Flow -- Inspired by Electrostatic Headphones

    The tuning change is a side issue, the change is an improvement in how air flows through the magnets, making the diaphragm move faster due to improved aerodynamics. This change would of course change the overall sonic characteristics requiring a matching change in the tuning to maintain the...

    As a writer I have been constantly told I should do more social media. The problem with that is I am old. How old you ask? I come from the world of patch bay sequencers. I can hear you scratching your head saying “Huh?” They were a very primitive form of computer that you programed by connecting...

    New DAC for HD800s

    You would be hard pressed to find a better sounding DAC than the CAS192D, it is very detailed and musical. It also has a choice of five different digital filters. The one caveat is if you are going to listen to DSD, only Windows is supported as it does not do DoP.

    Yes, gain noise is created by the circuitry between the volume control and the amplifier, since in this case the volume control take place before the DAC, we're looking at the base line noise level of the DAC itself, which may or may not be negligible.

    This was the original artist rendering of the QP1, it apparently never got replaced when actual photos became available. I will notify those in charge of the web page.

    An easy way to for the duplicates is to do a search for *.FLAC (or whatever file type you are using). Look for files of the same name with 0 file sizes, they will be the problem files.   Don't know of anything the player could have done to cause this. The player doesn't write anything to the...

    It sounds like you have data erase protection on your Mac. You may need to "Empty" your "Trash" to reclaim that space.
