01
Control and power apart
The S513i control amplifier optimises signal level distribution while the S514i power amplifiers use a dual-monaural layout to drive speakers efficiently.

The long listen
The S513i and S514i separate control from power for stable focus and spaciousness, with a warm, musical character that stays vivid without becoming tiring.
From the product description
The details that matter.
A short guide to the design and features described by Sparkler Audio.
02
Small units, flexible placement
Each unit is small enough to hold in one hand. The power amplifiers can sit near the speakers, and separation from the power supply reduces crosstalk.
03
Remote operation
The main units need only their power switches. The included remote controls operation, while front LEDs show the selected line input by colour.
04
Current-mode signal path
The current-mode design simplifies the signal path. A proprietary 32-step electronically controlled attenuator handles volume without mechanical contacts.
05
25-watt power stage
The S514i delivers 25 watts with a clear, sparkling, full-bodied sound and universal speaker terminals for different cable terminations.
