Upsamplers, DACs, jitter, shakes and analogue withdrawals, this is it.

RE: Actually a Bit too Much BS from PS Audio

I think the first company to do the multiple DACs was Accuphase back in the early 90s.

They had multi-multibit (MMB) where they used I think up to 16 BB PCM63K 20bit ladder DACs per channel.

Later they went to multi-delta/sigma (MDS) where they used multiple chips...this is more like what people are doing now with the ESS chips.

Aries Cerat still uses 18bit R2R chips (AD1865N) in multiples...I think the top model has 16 chips and that is a dual DAC chip for a total of 32 DACs in parallel per channel...it reduces noise and increases dynamics significantly.
