Demo'd the MS-1 for Nick today at HAL central as part of a checkout session for his Perpetual Technologies P-1A and P-3A combo. His P-1A was having problems. Turns out his battery supply for the P-1A was having issues not holding charge. Replaced his 12V-5AH AGM battery and it's back up and making music.
Used the MS-1 and M2Tech Evo via coaxial S/PDIF connection to drive the P-T gear. His P-1A has SOCS for his REF3 speakers, so he has that back working as well.
Always fun to get good old equipement back up and running!
Told him about Phil A's MAAC gathering next weekend, so he is going to look into it.
