Bitstream dac. The unit uses two boxes, one for digital processing and one for the conversion to analogue. Museatex DACs seem to have a cult following, since the vintage DAC presentation tends to sound more like an analog turntable than a cold sounding digital device. Philips took what they'd learned in dumbing-down their 'continuous calibration' ideas (started with the TDA1541) translated into trying to deal with the Vref -sensitivity of much cheaper-to-make cmos, bitstream, single-5v supply dacs for mass market. The modulator will be implemented with digital technology if you have a digital signal source and in analogue technique in case of an analogue signal source. To obtain an area efficient DAC design, periodic sequences are generated from sigma-delta modulators (ΣΔMs) using software, stores the sequence in memory and then passes it to a low-pass filter (LPF).
