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.

True underground, XX° century, former air-raid shelter... 🔊

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) 😎

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...

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...

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...

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...

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...

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...

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...

Airplay2, except for rare cases I think also Apple doesn't know, converts anything to AAC 256Kbit. Commercial radios, generally are not astounding with the bitrate. Also on Bluos, Arabella doesn't shine...

Could be interesting (if possible), to know what methods does WiiM use in upsampling process, that generally aren't so simple as believed. If it's an industrial secret, I understand and I'll keep upsample until Nad will fix their absurd incompatibility with 44.1KHz and it's integer multiples...

I can just say that I trust someone telling me there's a huge difference moving 20cm the speakers, than someone arguing about differences among (well working) digital interfaces or mains cables. 😎

Sure, anyone can have its own experience from listening and say anything about it but this not change the reliability that he could have and the trust someone could put on him. That's the reason why I don't like impressionists reviews. On other side, once someone got enough esperience on...
