💿 Onkyo DV-SP503E Super Audio CD Player — Sound Test with Technics SU-VX300 & Jamo M6 🔊

Описание: Welcome back to SpaceTime Engineering! In this session, we put the Onkyo DV-SP503E through a focused Super Audio CD (SACD) and CD listening test, driving a Technics SU-VX300 vintage integrated amplifier and Jamo M6 bookshelf speakers. Same discs, level-matched playback, tone controls flat — so you can judge the player’s sonic character without variables muddying the waters.

💿 Source: Onkyo DV-SP503E (Universal/SACD Player)

Disc support: SACD (stereo), DVD-Audio, CD (Red Book), DVD-Video; also reads MP3/WMA on optical media.

DAC/engine: 24-bit/192 kHz architecture with high-resolution filtering for smoother treble and finer low-level detail.

Transport & error handling: Quiet tray loading, solid disc stability; progressive scan video stage (unused here) electrically isolated from audio paths.

Connectivity: Analog stereo outputs (RCA), coaxial & optical digital outputs for use with external DACs/AVRs.

Takeaway in listening: On SACD material the DV-SP503E presents clean, airy highs, stable imaging, and low background hash; on standard CDs it leans smooth and fatigue-free rather than hyper-etched — great for long sessions.

🔊 Amplification: Technics SU-VX300 Vintage Integrated Amplifier

Design goal: Classic New Class A / Class AA-lineage Technics topology aimed at low crossover artifacts and confident current delivery.

Power output: Rated for typical 8 Ω hi-fi loads; lively, fast transient response with good grip on bookshelf woofers.

I/O & controls: Multiple line inputs (CD/Tuner/Aux/Tape loops), phono (MM) stage for vinyl days, tape monitor, loudness defeat, and straightforward bass/treble with precise detents.

What it brings to this test: A neutral, quietly authoritative amp that doesn’t hype the top end — ideal for revealing the source player’s differences on SACD vs. CD without adding glare.

⚙️ If you’re recreating this rig with another Technics “SU-V” family amp of similar era/specs, you can expect much the same voicing and dynamics.

📦 Loudspeakers: Jamo M6 Bookshelf Speakers

Configuration: Compact 2-way Danish bookshelf design.

Impedance & power handling: 8 Ω nominal, ~60 W rated (with music power headroom).

Sonic personality: A smooth, slightly warm midrange with easy-to-live-with treble; bass is tidy rather than thunderous, which makes it a smart partner when you want to spotlight front-end differences (like SACD vs. CD) instead of overwhelming the room with low-end boom.

Placement tips: 20–30 cm from the rear wall, mild toe-in. They reward solid stands and careful leveling for best imaging.

🎧 What We Test & How We Listen

SACD vs. CD of the same album/mastering where possible — level-matched within ±0.1 dB.

Acoustic & vocal tracks to check midrange purity and sibilance control.

Dense mixes (jazz ensembles, modern pop) to probe separation and transient handling.

Low-level passages for noise floor and micro-detail.

Result themes you’ll hear in the video:

SACD mode on the DV-SP503E tends to render finer ambience cues, cymbal decay, and soundstage depth a touch better than standard CD.

Through the Technics/Jamo chain, CD playback remains pleasingly smooth, with a slightly softer leading edge on transients — musical, non-fatiguing, and forgiving of hot masterings.

🧪 Test Bench Notes (for fellow audio nerds)

Signal chain: DV-SP503E analog outs → SU-VX300 line input → 2.5 m OFC speaker cable → Jamo M6.

Controls: Tone defeat; loudness off; input impedance compatible with the player’s output stage; power conditioned, warm-up 30 min.

Leveling: Pink-noise and RMS matching at listening position; C-weighted, slow integration.

Room: Small/medium living-room setup, near-field triangle ~1.9 m; first-reflection treatment; sub disabled.

🏁 Takeaways

If you value long-form listening with low fatigue, the Onkyo DV-SP503E into a vintage Technics amp is a sweet synergy.

The Jamo M6 keeps things honest: it won’t over-saturate the bass, so subtle SACD vs. CD differences are easier to hear.

Want more “snap” and slam? Add a musical sub crossed low (60–70 Hz) and you’ll keep the midrange clarity that makes this combo sing.
