“The DACs are four UltraAnalog 20-bit types, made of discrete and monolithic components encapsulated in a potted module, in a balanced configuration (left +, left –, right +, right –). The SDR-2000 Pro is unique among UltraAnalog-based processors in that the current-to-voltage (I/V) converters and sample-and-hold circuits are not incorporated into the potted DAC module. Instead, UltraAnalog makes a custom version exclusively for Spectral that allows Spectral to build discrete current-to-voltage and sample-and-hold circuits. The capacitors in the sample-and-hold circuit are the result of Keith’s years of searching for the ideal capacitor for this ultra-critical application. The I/V is an ultra-fast-slewing, direct-coupled, FET-based circuit that reportedly achieves fast settling time and low energy storage. According to Keith, this section of a digital processor is critical to sound quality.”
