    Spotify Spotify Lossless is here, it's official!

    This was I thought at a glance when switched from spot to Tidal but in reality is just a more clean and essential interface (no bells and whistles) and after a while I started to like it's suggestions, far more interesting than the usual mainstream from Spotify. In terms of connectivity...

    Spotify Spotify Lossless is here, it's official!

    Tidal cost less, pay more the artists, gives better suggestions, much more clean app and hasn't bullying behaviors versus minor editors...

    Spotify Spotify Lossless is here, it's official!

    Or simply let the files be as they're produced... This would avoid any complaint, and earable or not, everyone would be happy. The "main problem" isn't the bit depth or the sampling rate but the habit to make different masters. Despite the LUFS requirements by streaming services, producers...

    WiiM Amp Pro doesn't turn on subwoofer in auto mode (B&W ASW610)

    I think the line input of 610 was designed keeping in mind a full range signal incoming from pre amplifier. In my previous set-up it was turned on even by just the little "thump" noise from powering on the pre. Now I have a dedicated and filtered subwoofer output and it starts only if overall...

    "re-clocking" the Ultra digital out ?

    This paper from Audio Precision is about jitter measuring techniques but has a chapter well describing what is jitter. To resume: jitter affects any change of domain and there are three kind of it: AD, interface and DA. AD stage is matter of studio recording equipments and no control by the end...

    What was your first hi fi equipment?

    It's me, but I'm having a hard time thinking of any similarities. Anyway, almost all the equipment came from the scrapyard, and some I built myself. We certainly hadn't yet figured out that loudness isn't everything.

    More line level output settings please

    Absolutely but I'm on "Do It Yourself" side and enjoy it... Anyway the improvements of S/N ratio are true (and difficult to ear too) 😎

    More line level output settings please

    If you want to rely on "analog adjustment" and not involve resampling on digital domain as WiiM volume does, why don't make a resistive divider, directly on the cable, or in a little metal box, possibly with a potentiometer. If don't like to use soldering, some ready made are available. If you...

    SPDIF or Toslink out? Why?

    I think the only advantage of usb is the capability to carry higher sample rate, even if not so diffused, someone could need to play it. The clock in usb audio is quite sure asynchronous, set by the dac but also for spdif and toslink (capped just on very cheap devices) is the PLL of the input...

    SPDIF or Toslink out? Why?

    If something hasn't changed, USB audio uses the isochronous real time transfer protocol. It has CRC like the bulk transfer used to reliably transfer data but differently from the latter, in case of error anyway no resending is done. Probably there isn't a clear superiority for the usb...

    SPDIF or Toslink out? Why?

    Since the same protocol is used, any differences, if present and not due to traditional biases, may depend on a case-by-case basis, the design and quality of the coupling: mechanical precision for Toslink, electrical coupling for coax, and circuitry for both. Regarding jitter, the so-called...

    WiiM Amp Pro doesn't turn on subwoofer in auto mode (B&W ASW610)

    I have the same ASW610 and confirm that its auto power on it's not so sensitive . Correct to increase the amp sub output while reducing the input knob. Also, tests don't show particular differences among filter off and maximum freq cut-off, anyway setting it off, involves less circuitry and...

    Mix tapes

    More than mixes I would say Playlists on tape, alongside with LP recorded, one on C45 or two on C90 (and some spares to fill). When Dolby C arrived, it was a giant step to "quality". I still have all my all old tapes and the same recorder, perfectly operational and sometimes, I play some...

    What speakers are you using?

    Looking at the combined response I could guess there is some combing cancellation, due to reflected wavelengths correspondingly to 4 times the distance from the back wall. Give the frequency I roughly calculated about 42cm.You could try to reduce the distance of speakers from the back, inserting...
