If you like the unique sound of your Sonics, then having them refurbished (if in workable shape) is possible, or suggest upgrade to newer DSM-6S/L or louder handling /EL set.
Mic models and customer service is discussed on page:
www.sonicstudios.com/dsm.htmMany have had DSM mic sets from earlier times running on stock Sony DAT D7/8 models
directly powering these mics in an OK manner or best with MOD-2 mic powering internal deck upgrade.
However, some updated to the newer/way better performing D100/M1 Sony deck
THAT DOES NOT POWER DSM mics in an acceptable manner causing gross distortions at higher loudness levels. These Sony decks need MOD-2 internal upgrade, or PA mic powering adapter, or external mic powering preamplifier.
DSM mic powering options are discussed with solution options depending on deck models at:
