Keep it simple (KISS).....
Ok...Here's my ideas
Don't look back at the past, this is a totally new venture with a couple of legends at the helm....
DR Audio
DR Audio Specialties
RD Audio
RD Audio Specialties
R&D Audio
R&D Audio Specialties
"R&D" could be construed as Richie & Dodd or "research & development" both are appropriate.
"Specialties" Would mean non main stream, as in battery powered, or chip amp.
A couple of my thoughts about the offering:
When I think of "chip" amps, I think "Cheap & Cheerful" not high end audiophile gear. I really like playing with chip amps because they are so CHEAP, and sound great, not something I would spend much for though.
If the amps/preamps are offered as primarily battery powered, it may limit the audience. Not everybody is ready to deal with batteries. Offer either the battery or a DC PS as equal, with the battery power as a recommended "best" choice, but not necessary for great sound.
A USB only DAC also limits the audience. It might be best to rethink that.
Stay with the unique Dodd style chassis/cases. They are unequaled for looks.
Just my thoughts....
