...and measurements to back it up.With some DACS claiming (and apparently getting) -140db, there was still work to be done.
About 10 years ago, high-bit converter chips began to disappear. The Burr-Brown 1704, Burr PCM63K, Analog Devices AD1862N, Ultra Analog D20400. With these gone, co. were trying to push the noise-floor down, with lesser, high-noise chips.
Stereo-2 chan., upsampling, volume control, clock oscillators -all these were forced on the Delta/Sigmas that flooded the market.
So here's what they did:
'Off-loading' -co.'s 'stripped the chip' of functions (more discrete): Auralic, EMM, Bricasti and I can imagine Ayre (and more, but these are a few).
New, ground-up R2Rs: MSB, Totaldac, Metrum, Mola Mola. Some incorporate FPGAs.
'Latch type' w/FPGAs for DSP: Playback Designs, PS Audio (and Nagra ? for a price)
Then, the AK 4490 -a new chip from the orient. Hegel's HD30 DAC uses it. Got reviewed twice by the U.K., once by 'Soundstage' -and it could be a breakthrough.
But probably not for long - DACs are red-hot right now !!
