The liberation of sound. How I got the best sound ever in my listening room.
The liberation of sound. How I got the best sound ever in my listening room. Is your passive crossover limiting your system’s potential? In this video, I explain why I removed the passive crossover from my system and replaced it with a purely analog line-level solution (PLLXO). This approach allows true bi-amping without DSP, without L-pads, and without large inductors in the signal path. Wideband drivers offer purity and coherence. Dedicated bass modules offer scale and authority. The real challenge is integration — without choking dynamics or transparency. This is how I solved it. ⸻ What you’ll discover: • The Bi-Amp Interface – a passive line-level crossover built into a stabilized Y-cable • Why analog sources (vinyl, high-end DACs) deserve an all-analog signal path • How a 300B tube amplifier pairs with OKHO widebanders • Why a solid-state or V12 amplifier can be ideal for BOB bass modules • CLIO measurements proving the precision of a 1st-order roll-off • What changed in real listening — articulation, scale, spatial clarity “The speakers were no longer playing. They were breathing.” ⸻ If you’re exploring modular loudspeaker systems, bi-amping, or chasing the final 5% of performance, this deep dive is for you. ⸻ Explore the Gear 👉 Stereopolis Direct-to-Consumer Store (OGY / OKHO / BOB / BLOCKS) www.stereopolis.com 👉 Closer Acoustics philosophy and design approach ⸻ Timestamps 0:00 The Quest for the Perfect Sound 1:01 The Passive Crossover Problem 2:58 Why I Avoid Digital DSP 3:55 Introducing the Bi-Amp Interface (PLLXO) 4:33 Removing the Passive Components 5:02 Amplifier Pairings: 300B + Solid State 6:14 Total Control with First-Order Division 6:57 Listening Session Begins 7:24 Take Five – Articulation & Air 8:11 Murder by Numbers – Rhythm & Control 9:01 Final Thoughts: Removing the Obstacles ⸻ #Audiophile #HighEndAudio #BiAmping #TubeAmplifier #WidebandSpeaker #AnalogAudio #CloserAcoustics #HiFi
