                        <content:encoded><![CDATA[<p>The psychology of audio perception involves a strong placebo effect: price tags, brushed aluminum faceplates,VU meters, and prestige branding can easily bias what you think you hear.</p>
<p>&nbsp;</p>
<p>High-End Audio Brands vs. Automotive Equivalents</p>
<p>High-end audio brands mirror luxury automotive manufacturers in engineering philosophy, heritage, and status symbolism:</p>
<p>&nbsp;</p>
<p>Audio Brand Automotive Equivalent Brand Persona &amp; Engineering Focus</p>
<p>Krell Bugatti / Corvette Z06 Raw American power, massive current delivery, unrestrained dynamics.</p>
<p>Accuphase Lexus / Toyota Century Meticulous Japanese precision, signature champagne finish, total reliability.</p>
<p>Luxman Aston Martin Classic elegance, warm aesthetic, refined heritage with modern performance.</p>
<p>McIntosh Cadillac / Bentley Iconic blue VU meters, unmistakable bold styling, effortless power.</p>
<p>Gryphon Audio Lamborghini Dark, dramatic aesthetic, brutal power reserves, uncompromising design.</p>
<p>Burmester Porsche German engineering perfection, ultra-clean chrome finishes, high precision.</p>
<p>Grimm Audio McLaren Modern high-tech performance, master-clock precision, engineering over nostalgia.</p>
<p>Audio Research Ferrari Pure emotional engagement, high-performance vacuum tube craftsmanship.</p>
<p>Key Audio Truths</p>
<p>Source Quality ("Garbage In, Garbage Out"): A ultra-resolving setup featuring a Grimm Audio MU2 will expose harshness and compression in bad recordings far more than a budget streamer like a Bluesound Node 2i. High-end gear acts like a magnifying glass—it amplifies both perfection and flaws.</p>
<p>&nbsp;</p>
<p>The Class D Revolution: Audiophile performance was once exclusive to power-hungry Class A or tube designs. Modern Class D technology (such as Purifi Eigenakt and Hypex modules) achieves near-zero distortion and ruler-flat frequency responses in efficient, compact form factors.</p>
<p>&nbsp;</p>
<p>Acoustics over Price Tags: Room reflection and speaker placement dictate up to 50% of what you hear. A $20,000 system in an untreated room with hard surfaces will consistently sound worse than a $2,000 system set up in a acoustically tuned space where 3D imaging and soundstage depth can actually materialize.</p>]]></content:encoded>

                        <content:encoded><![CDATA[<p>Bought the same  —or so I thought— KRK12s subwoofer, but the distortion —hadn't looked at the user manual— normally professional equipment is +4dB. But this one is an improved version, well, improvement?!! They’ve made this one suitable for -11dB now, don't count on that, so clipping, so set to +4dB, Energy saving mode also turned off; the guys behind the controls don't bother to set the recording to 0dB. And if you turn up your preamp 14dB, a gigantic volume comes out of the next track. Turned off?!! If the volume is too low for too long, you won't hear anything anymore, because the subwoofer is in standby mode, after which the volume first has to be turned up much louder -far from convenient- How did they come up with the idea to consider these changes useful!?!!</p>]]></content:encoded>

                        <content:encoded><![CDATA[<p>Don't forget to turn off Bluetooth; the connection often fails if Bluetooth is still on.</p>
<p>AirPlay 2 offers the best sound quality in almost all practical situations, with an important caveat regarding the Bluetooth codecs and settings used. AirPlay 2 (Wi-Fi) • Transmission: Works over your Wi-Fi network with much higher bandwidth than Bluetooth. • Audio Quality: Transmits audio up to 16-bit / 44.1 kHz (CD quality) uncompressed (ALAC). • Caveat: With some apps (like Apple Music on iOS), AirPlay 2 can under certain circumstances switch back to 256 kbps AAC (lossy). Nevertheless, the signal remains very stable and free of aggressive data compression. Latest Bluetooth Version (Bluetooth 5.3 / 5.4) • Transmission: Direct connection between phone and speaker/headphones with limited bandwidth. • Audio Quality: The Bluetooth version itself (like 5.3 or 5.4) mainly determines range and energy consumption, not sound quality. The quality is determined by the supported audio codec: - SBC / AAC (standard on iPhones, among others): Compressed (lossy), with a noticeable loss compared to Wi-Fi. - aptX HD / LDAC / LHDC (Android): High-res codecs that come close to CD quality or lossless, but still compress dynamically based on the connection. - aptX Lossless (Snapdragon Sound): Can transmit true 16-bit/44.1 kHz lossless audio, but requires both your smartphone and your headphones/speaker to specifically support it (iPhones do not support this). Comparison • Maximum Quality: AirPlay 2 = CD quality (16-bit/44.1 kHz); Bluetooth = Up to Lossless (only with aptX Lossless on compatible Android devices). • Standard Quality: AirPlay 2 = Lossless ALAC or high-quality AAC; Bluetooth = Compressed (AAC / SBC) on most devices. • System Interference: AirPlay 2 = None (calls/notifications do not interrupt music); Bluetooth = Notifications and ringtones play through your speakers. • Compatibility: AirPlay 2 = Only within the Apple ecosystem / Wi-Fi; Bluetooth = Universal (iOS, Android, Windows, Mac). Conclusion: For home use with an Apple device and a good speaker (like Sonos or HomePod), AirPlay 2 delivers the best, most consistent sound. Bluetooth only wins in terms of portability outdoors or with specific high-end Android hardware and aptX Lossless equipment.</p>]]></content:encoded>

                        <content:encoded><![CDATA[@lars-b-j  A system is only as clean as its weakest link. As components become more revealing, they do not just reproduce more detail from the music—they also reveal system noise, power hash, and interference that budget gear typically masks.
<div> </div>
<div>Here is how power quality and cable shielding impact your setup, along with practical ways to optimize them:</div>
<div> </div>
<div>1. Power Supply as the Foundation</div>
<div>An amplifier does not create sound out of nowhere; it uses the AC voltage from your wall outlet to modulate the audio signal sent to your speakers. If the incoming power is contaminated with radio frequency interference (RFI), electromagnetic interference (EMI), or DC offset from household appliances, that noise rides right along with the signal.</div>
<div> </div>
<div>Lowering the Noise Floor: Dedicated power conditioners like the AudioQuest PowerQuest 3 filter out high-frequency line noise and protect against voltage spikes. The practical result isn't necessarily "brighter sound," but a lower noise floor—meaning blacker backgrounds, finer dynamic contrast, and clearer micro-details at lower listening volumes.</div>
<div> </div>
<div>Current Delivery: When choosing power conditioning, ensure power amplifiers and powered subwoofers are plugged into high-current outlets so dynamic punch isn't constrained during sudden musical peaks.</div>
<div> </div>
<div>2. EMI/RFI and Cable Management</div>
<div>Cables behave like antennae. Low-level analog signals (like RCA line-level interconnects or phono stage outputs) are especially sensitive to stray magnetic fields generated by power transformers, wall warts, and Wi-Fi routers.</div>
<div> </div>
<div>Crossing at 90 Degrees: If power cables and signal cables must cross each other, route them perpendicularly (at a 90-degree angle). Running power cords parallel to interconnects creates inductive coupling, introducing a 50Hz/60Hz mains hum or high-frequency buzz into your audio signal.</div>
<div> </div>
<div>Proper Shielding and Termination: Well-constructed interconnects use braided shielding (or twisted-pair geometry) and well-machined metal connectors to create a Continuous Faraday cage around the conductor, rejecting airborne interference before it reaches your amplifier stage.</div>
<div> </div>
<div>Separation: Keep digital sources, modern switching power supplies (like phone chargers or TV power bricks), and Wi-Fi access points on a separate power strip or physically distant from your sensitive analog components.</div>
<div> </div>
<div>Kind regards and happy listening</div>]]></content:encoded>

                        <content:encoded><![CDATA[<p>The Audiophile’s Illusion: Why the Best Sound System Is Useless Without the True Source</p>
<p>Audiophiles invest thousands of dollars into high-purity copper cables, tube amplifiers, acoustic treatment, and advanced DACs. Endless debates rage over DSD resolution and the micro-details of frequency response. Yet in this relentless pursuit of perfect sound, the most critical element of all is routinely overlooked: the source. The most expensive sound system in the world can do no more than reproduce what is present in the recording. And right there, a quiet tragedy is unfolding.</p>
<p>&nbsp;</p>
<p>Many of the most magical, unique, and emotionally moving performances in music history have silently vanished from streaming services. What remains on platforms like Spotify or Apple Music is frequently an over-compressed, flattened reissue or simply the wrong master altogether.</p>
<p>&nbsp;</p>
<p>The Musician Creates the Painting; the Score Is Merely the Canvas</p>
<p>A common misconception is that music is identical to the musical score on paper. Consider painting or classical composition: a score by Mozart or a sketch by Rembrandt is only the starting point. It is the musicians—the virtuosos, as well as the anonymous studio and session players—who bring the work to life. Their timing, dynamics, and subtle imperfections in touch or breath give a piece its soul. No musician plays a piece identically twice, and that one specific recording on that one particular day might be a historic masterpiece.</p>
<p>&nbsp;</p>
<p>When such a unique performance is replaced by a flatter re-recording or a digitally butchered remaster, the essence of the artwork is lost. A hundred-thousand-dollar audio setup then merely delivers a crystal-clear reproduction of a mutilated source file.</p>
<p>&nbsp;</p>
<p>Vanished and Superior Performances: An Overview Across Decades</p>
<p>The phenomenon of "lost gems" spans every genre and decade. One of the most striking examples comes from the world of Gypsy and folk music, but the same principle applies to classical, jazz, rock, and pop.</p>
<p>&nbsp;</p>
<p>+--------------------------------------------------------------------------------------------------------------------------+</p>
<p>| A STRIKING EXAMPLE: COLEA SERBAN &amp; THE HARRY DE GROOT ORCHESTRA |</p>
<p>| |</p>
<p>| On modern streaming platforms, you can at best find the reissue of pianist Colea Serban with the Harry de Groot |</p>
<p>| Orchestra (such as the well-known version with the yellow cover). However, the original pressing (featuring a woman |</p>
<p>| on the cover, released on labels like Fontana) possesses a dynamic range, sense of space, and musical spontaneity |</p>
<p>| that is incomparably superior. The arrangements and vinyl pressing of that specific release breathe a vitality that |</p>
<p>| has been completely flattened on later reissues and digital streaming files. |</p>
<p>+--------------------------------------------------------------------------------------------------------------------------+</p>
<p>1. Classical &amp; Baroque (1950s–1970s)</p>
<p>Willem Mengelberg &amp; The Royal Concertgebouw Orchestra: Many of Mengelberg's original Shellac 78 rpm and early LP pressings captured the natural acoustic balance of the Concertgebouw hall. Modern digital noise-reduction filters tend to slice away string overtones and natural room acoustics along with the background hiss.</p>
<p>&nbsp;</p>
<p>Sergiu Celibidache: Celibidache famously refused to make studio recordings during his lifetime, believing that the acoustic space and the moment were unique. The few authorized live recordings released posthumously have often been replaced on streaming platforms by poorly mastered bootleg versions that destroy the orchestral balance.</p>
<p>&nbsp;</p>
<p>2. Jazz (1950s–1960s)</p>
<p>Miles Davis – Kind of Blue (1959): For years, Side A of this iconic album played at the wrong pitch due to a slipping motor on the studio tape deck at 30th Street Studio. While this was corrected in 1992, many audiophiles still prefer the original 1959 mono mix for its direct, unvarnished balance of instruments, which was compromised in subsequent stereo remixes.</p>
<p>&nbsp;</p>
<p>Bill Evans Trio – Sunday at the Village Vanguard (1961): The original analog Riverside pressings captured the room's atmosphere, background chatter, and the delicate brushwork of drummer Paul Motian. Modern digital versions often sound "cleaned up," stripping away the ambient magic of that live moment.</p>
<p>&nbsp;</p>
<p>3. Soul, Funk &amp; R&amp;B (1960s–1970s)</p>
<p>The Funk Brothers (Motown) &amp; Booker T. &amp; the M.G.'s (Stax): The irresistible groove of Motown hits was forged by the unsung genius of session musicians. The original mono single mixes were tailored specifically for maximum impact on AM radio and turntables. On streaming services, these are almost exclusively replaced by later stereo mixes, where James Jamerson's baseline loses its central drive and impact.</p>
<p>&nbsp;</p>
<p>4. Rock &amp; Progressive Music (1970s–1980s)</p>
<p>Steely Dan – Aja (1977) &amp; Gaucho (1980): Donald Fagen and Walter Becker were obsessed with audio fidelity, hiring dozens of top session musicians for a single solo. The original AB-1006 vinyl pressing of Aja (cut from the original master tape) is considered a holy grail. Many subsequent CD reissues and streaming tracks were made from second- or third-generation copy tapes because the original master tape suffered physical damage.</p>
<p>&nbsp;</p>
<p>Frank Zappa: In the 1980s, Zappa released digital remixes of his classic 1970s albums (such as Hot Rats and We're Only in It for the Money), sometimes going so far as to re-record bass and drum tracks. The raw, original vinyl mixes featuring the original personnel are virtually impossible to find on streaming services.</p>
<p>&nbsp;</p>
<p>The Bottom Line</p>
<p>For the audiophile, a cold reality applies: Garbage in, garbage out. Investing in ultra-high-end audio gear only makes sense if the source remains true to the original artistic moment. As long as the music industry allows master tapes to deteriorate or replaces them with digitally brickwalled remasters, we aren't listening to the music itself—we are listening to a shadow of what those musicians created in the studio.</p>
<p>&nbsp;</p>
<p>Draft Email to Record Labels, Archives, and Streaming Platforms</p>
<p>Subject: The irreversible error in preserving our musical heritage and master tapes</p>
<p>&nbsp;</p>
<p>To: The Management and Archival Teams at Universal Music Group, Sony Music, Warner Music, Sound &amp; Vision Institute, Spotify, and Apple Music</p>
<p>&nbsp;</p>
<p>Dear Management and Cultural Heritage Guardians,</p>
<p>&nbsp;</p>
<p>It is with growing dismay and concern that I observe how our most precious musical heritage—the original analog master tapes and unique historic performances by master musicians—is currently being handled.</p>
<p>&nbsp;</p>
<p>In the pursuit of operational efficiency and digital standardization, a major artistic blunder is taking place. Music written on paper is merely a framework; it is the specific musicians, arrangers, and sound engineers who capture an unrepeatable moment in time to create a masterpiece. Every performance is unique.</p>
<p>&nbsp;</p>
<p>It is therefore incomprehensible that:</p>
<p>&nbsp;</p>
<p>Definitive Masterpieces Are Disappearing: Superior original recordings and mixes—such as the iconic early performances of Colea Serban with the Harry de Groot Orchestra (the original Fontana pressing)—have been purged from streaming platforms or replaced by artistically inferior, dynamically flattened reissues (such as the later yellow-cover pressing).</p>
<p>&nbsp;</p>
<p>Master Tapes Are Physically Perishing: Due to poor climate storage, countless analog tapes have succumbed to sticky-shed syndrome. Furthermore, events like the tragic 2008 Universal Studios fire have demonstrated how vulnerable this heritage remains when no physical and high-resolution digital preservation of the unprocessed, original masters exists.</p>
<p>&nbsp;</p>
<p>Dynamic Compression Is Destroying the Magic: Today's streaming catalogs are dominated by "remasters" that fell victim to the Loudness War. Human dynamics and the delicate touch of the performing musicians are crushed in favor of a maximized digital signal.</p>
<p>&nbsp;</p>
<p>An audio system can never sound better than its source. When an original recording is lost or replaced by a mediocre copy, a piece of our cultural history disappears forever.</p>
<p>&nbsp;</p>
<p>I urgently call upon your organizations to:</p>
<p>&nbsp;</p>
<p>Prioritize the preservation and digitization of original analog master tapes without applying dynamic compression or intrusive digital processing.</p>
<p>&nbsp;</p>
<p>Restore access to historic alternate pressings and original mono/stereo mixes on public platforms, rather than restricting catalogs to the latest standardized reissue.</p>
<p>&nbsp;</p>
<p>Provide full transparency regarding the provenance and source chain (master source) of files delivered to streaming platforms.</p>
<p>&nbsp;</p>
<p>Music is no different from fine art: we would never replace an original Rembrandt with a digitally retouched poster. Do not allow the original performances of our greatest musicians to fade into permanent obscurity.</p>
<p>&nbsp;</p>
<p>Sincerely,</p>
<p>&nbsp;</p>
<p></p>
<p>&nbsp;</p>

<div>The galvanic isolation has a significant impact on sound quality.</div>
<div> </div>
<div>Highly recommended if you want to get the best out of your Nilai amplifiers.</div>]]></content:encoded>
