Know before you buy
Using a dedicated DAC chip for each channel significantly improves channel separation and reduces crosstalk. This results in a more expansive, precise soundstage and greater clarity in your music.
Yes, the AMG PRA features adjustable volume per input. This allows you to normalize the playback levels across your various components so you don't experience sudden volume jumps when switching sources.
Yes, it supports native DSD playback. This ensures that high-resolution files are processed in their original format without unnecessary conversion, preserving the integrity of the recording.
The SRC IC chip handles digital up-sampling to the megahertz range. Its primary function is to minimize jitter, which helps produce a cleaner, more stable signal for a more natural analog sound.
Yes, the AMG PRA is designed with an all-discrete output stage and provides balanced XLR outputs with a 4 Vrms output voltage, making it an excellent choice for high-end balanced audio setups.
The unit utilizes the Muses 72320 volume control, which is a high-precision, low-noise resistor ladder design. This provides much greater accuracy and transparency compared to traditional mechanical volume pots.
