Mezmo my experience with the MHDT Havana could not be more different than yours concerning detail at low listening levels. I feel no need to turn up the volume, all the music and low level information is there along with natural dynamics and the amazing tonality of this unit at very moderate listening levels. I can expect as with any product that it may be system dependent but for a NOS DAC with USB and tube output, this is one hell of a performer and less than 1K to boot and worthy of consideration.
