Good gear doesn’t make you hear more — it makes you hear more truthfully.
My Setup#
| Device | Model | Role |
|---|---|---|
| DAC/Amp | TOPPING DX5II | All-in-one DAC + preamp + headphone amp |
| Headphone | Sennheiser HD600 | Open-back dynamic flagship |
| Cable | Stock cable | Haven’t upgraded yet |
Why This Combo#
The HD600 is a timeless classic. With 300Ω impedance and open-back design, it delivers a natural, spacious soundstage and precise midrange reproduction. It doesn’t win with treble sparkle or bass rumble, but strives for authentic instrument reproduction.
The DX5II as an all-in-one has more than enough power to drive the HD600. The ESS9038Pro DAC chip + NFCA amp module offers excellent noise floor control, and the compact size fits nicely on a desk.
Listening Impressions#
Genres That Shine#
- Classical — The HD600’s soundstage and midrange density make string quartets and vocals utterly captivating
- Jazz — Saxophone and piano timbre come through beautifully
- Acoustic / Vocal-focused — Warm mids without muddiness
Genres That Struggle#
- Electronic / EDM — Bass extension and quantity are conservative, not party-worthy
- Metal — Transient response is just okay, can get slightly chaotic on big dynamics
Usage Scenarios#
I mainly use this setup for:
- Late-night coding sessions with classical or jazz
- Weekend afternoons for focused full-album listening
- Comparing different recording versions (the DX5II’s detail retrieval is sufficient for this)
Future Upgrades#
- Try balanced cable + balanced output
- A/B test against HD650 / HD6XX
- Get a dedicated headphone amp for comparison (e.g., Schiit Magni)
Listening is highly subjective — these are just my personal impressions.
