Marantz PMD-661MKIII with the Super MOD installed and shipped via USPS 2 day priority mail in the 48 states.
The Marantz PMD 661MKIII Super MOD upgrade rebuilds the XLR inputs using very high speed, very low noise and super low distortion op amps that dramatically improve low level detail and clarity. Components are selected by ear to optimize detail and low level resolution. Super low THD+N op amps especially designed optimal performance in low rail voltage portable gear allow for a very wide SFDR even with signal levels down 50dB. This preserves the signal quality of the highest grade microphones when recording soft signals, like voice, un amplified music, nature sounds and FX.
