Product description
The Diamond is a high-end DAC and preamplifier built for serious digital audio systems. It converts high-resolution PCM and DSD signals with extremely low distortion and high dynamic range, then feeds a clean, powerful analog signal to power amplifiers or active speakers. Designed around SPL’s high-voltage analog technology, it offers wide headroom, precise detail and a very neutral, transparent sound signature, suitable for both audiophile and professional studio environments.
