§ Technology Resolution · Signal Path · Room Correction · Remote Service

What actually shapes how it sounds.

Specifications matter only insofar as they show up at the seat. This page lays out the technical decisions that move the needle for a private listener: the resolution we keep, the signal path we protect, the way the room is corrected after the room is treated, and how the system stays in tune over time.

RESOLUTION · BIT-PERFECT PLAYBACK · DIGITAL ROOM CORRECTION
§ 01
Resolution

The recording, at its native resolution.

Digital audio quality starts with two numbers — bit depth and sample rate. Bit depth determines dynamic range and noise floor; sample rate determines the highest frequency the file can carry. CD-quality is 16-bit / 44.1 kHz, which gives roughly 96 dB of dynamic range and a 22 kHz ceiling. High-resolution recordings extend both: 24-bit gives roughly 144 dB of dynamic range, and sample rates of 96 kHz and 192 kHz move the digital ceiling well above any audible frequency.

The audible question is whether the additional resolution survives the chain between the file and the listener. In practice it almost never does, because most playback paths re-sample, mix, and process the signal at a fixed lower resolution before it reaches the converter. We design the playback chain to avoid that — to deliver the recording to the digital-to-analog converter at its native rate.

DSD recordings, native PCM at 192 kHz, and lossless streaming services are all handled at their original resolution where the source allows. Master-quality streams from Qobuz, Tidal, and Apple Music Lossless pass through without resampling unless the architecture forces it. Where it does, you'll know — and you'll see why in writing.

Resolutions Handled Natively
PCM
16/24-bit at 44.1, 48, 88.2, 96, 176.4, 192 kHz
High-rate PCM
24/32-bit at 352.8 and 384 kHz where source supports
DSD
DSD64, DSD128, DSD256 (DoP and native, depending on DAC)
Streaming
Qobuz Hi-Res, Tidal Max / FLAC, Apple Music Lossless — at source rate
Local
Roon or comparable, library managed and metadata-curated
§ 02
Signal Path

Bit-perfect, where it should be.

A signal path is the route a sample takes from its source to the speaker. Every node on that path is an opportunity to alter the signal — sample-rate conversion, mixing, software processing, jitter introduced at clock boundaries, latency added by buffering. Done well, those nodes are deliberate. Done poorly, they are silent compromises.

We design the digital path to be bit-perfect from source to digital-to-analog conversion: no unrequested resampling, no software mixing, no shared output device with an operating-system audio stack that re-clocks the signal. Where digital signal processing is intentional — room correction, time alignment, crossover work — it happens at known precision, with documented parameters, after the bit-perfect path has done its job.

On the analog side, the chain is matched to the speakers and the room. Active loudspeakers use their own internal amplification and crossovers. Passive systems are amplified externally, with amplifier topology and damping factor matched to the load. Cables are specified to length and impedance, not to mythology.

Signal Path Principles
Source
Native-rate playback; bit-perfect transport; no OS-level mixing
Clocking
Master clock at the DAC; word-clock distribution where multi-source
Processing
DSP at intentional points only; documented parameters; recoverable
Conversion
DAC selected per program — chip topology matched to system character
Amplification
Topology and damping matched to load; measured at the speaker
§ 03
Digital Room Correction

Correction is the last step — never the first.

A room imposes a frequency response of its own on whatever plays in it. Standing waves at low frequencies, reflections at mid frequencies, absorption from soft surfaces — the room is part of the system whether you measure it or not. Most consumer playback ignores this. Most high-end playback that addresses it does so badly, by applying broad equalization at the speaker level and calling it correction.

We treat the room first — diffusion, absorption, isolation — and apply digital correction last, against a measured baseline of what the treated room is doing. Correction is targeted at specific modal behaviors and time-domain anomalies, not used as a substitute for acoustic work. The goal is a system that sounds the same in the seat regardless of where the recording was made and what speakers reproduce it.

Correction parameters are stored, documented, and recoverable. They are revisited annually as part of ongoing service, and they update as furniture moves, drapery is added, or the room otherwise changes. The measurement work that justifies them never goes stale, because we keep measuring.

Correction Methodology
Sequence
Treatment → measurement → correction. Never the reverse.
Domain
Frequency and time-domain correction (impulse response, group delay)
Targets
Modal behavior, early reflections, low-frequency integration
Baseline
Measured at the listening position, not at the speaker
Revisits
Annual re-measurement; correction updated remotely as the room changes
§ 04
Remote Service

Service without a service visit.

Once a system is installed and tuned, ongoing service rarely requires anyone in your home. We deploy a hardened, encrypted access path to the audio system that lets us read measurement data from in-room calibration microphones, adjust DSP and digital room-correction settings, diagnose component faults, and apply manufacturer firmware updates — all without disturbing the system or the household.

For clients whose homes are not casual environments — where every visit is a coordination — this is the difference between an annual tuning being a one-week project and a one-hour remote session. It is also the difference between a small problem becoming a large one and a small problem being resolved before you notice it.

The remote path is single-purpose. It reaches only the audio system, requires hardware-based authentication on our end, and every session is logged and reviewable by you on request. We do not see traffic on your other networks, video feeds, control systems, or any device outside the audio system.

Remote Capabilities
Diagnosis
Component status, fault detection, signal-path verification, predictive monitoring
Tuning
DSP parameter changes, digital room correction, level and EQ at the seat
Updates
Firmware, processor, and streaming-platform updates during low-use windows
Access
Encrypted, single-purpose, hardware-authenticated. Logged and reviewable.
Scope
Audio system only. No visibility into other networks, video, or control systems.

A Note on Networks

The means, not the message.

01
Bandwidth headroom
High-resolution audio and multi-room synchronous playback need bandwidth headroom that older home networks do not always provide. Modern wireless (Wi-Fi 7) and multi-gigabit wired backhaul provide it comfortably. The network is sized to the program with margin to spare.
Sized to the program
02
Wired where it matters
Wireless is appropriate for many things and not appropriate for others. Listening rooms, theaters, and head-end equipment racks get dedicated wired runs. Distributed playback to less-critical zones runs over the wireless network where latency and jitter are not in the critical path.
Wired vs. wireless by program
03
Isolated by design
The audio system runs on its own network segment, isolated from guest devices, IoT, and surveillance traffic. The audio network is not visible from the rest of the home, and remote service reaches only the audio segment.
Network segmentation
04
Coordinated, not collided
Where existing AV ecosystems are in place — Crestron, Control4, Savant, Lutron — our network and audio infrastructure runs alongside them, not instead of them. We coordinate with your integrator on shared backhaul and control surfaces.
