The incredible Accuphase DC 61 DA convertor

[@femkevoorn6932]

Accuphase has taken aim at improving the weak point of multibit-type DACs-namely, inferior linearity at low-level signals. Their assault on the state of the art can best be described as brute force in nature. A Multiple MultiBit (or MMB, for short) type of DAC is used in the DC-61 processor. This type of DAC uses a number of multibit DACs in a parallel drive configuration. Theoretically, the noise floor, hence the conversion error in an MMB system, decreases by 3dB every time the number of paralleled identical DACs doubles. If 12 DACs are used per channel, then the error would decrease by a significant factor. Believe it or not, that's exactly what Accuphase did! Imagine 12x a 20-bit, hand-selected, Burr-Brown, multibit DACs (each a PCM63P-K) in parallel for each channel-that's a total of 24 DACs! The payoff is a substantially lower noise floor and amazing linearity down to the theoretical capability of an ideal near-20-bit DAC. The DC-61 signal/noise ratio of is truly state of the art!

That info is incorrect. The DC-91 uses 16x Burr Brown PCM-63k per channel-(best dac chip ever?), the DC-91 uses 6x Burr Brown PCM1702 per channel- a great 90s r2r dac chip. I own a DC-91 and love it-though it is not perfect-the bass impact is a bit loose and flabby for my liking-though it could be up for a recap obviously. The DC-61 interests me because of how much extra space there is to mod/upgrade.

I listen to DC-61 to the tube amp Hagerman Tuba through Focal Clear. Not bad. :)

Oh yes 💕✔️

I have one.I have tried a lot of modern DACs and none of them sound as good .

I picked up an Accuphase dc80 from the late 80s and was shocked how good it sounds compare to modern stuff
