d1-core DAC

The d1-core is a more affordable Totaldac DAC but also very optimised to be very musical and natural sounding.
Some parts are optimised to give a better performance/price ratio but it still uses exactly the same ladder resistors and the same FPGA as the other Totaldac DACs.
This makes the d1-core an incredible performer in its price range and up.

"The DAC sounds just fantastic. It’s one of the most natural-sounding, almost vinyl-and-valve like converters you can get for the money and beyond." Alan Sircom, hi-fi+
"The Totaldac d1-core is the most fluidly organic digital component I’ve experienced…"
"In terms of tonal purity, extraordinary beauty and effortless musicality the Totaldac d1-core has eclipsed several higher-ticket/high profile digital units I’ve reviewed recently."
"My system sang, ergo, an easy Blue Moon Award. Simply put, I loved it!" Edgar Kramer, Senior Reviewer, 6moons
"The response is one of the most balanced and linear that we heard from a DAC at any price.
Isn't it the secret of the musicality of Totaldac DAC in general and specifically of the d1-core?
One thing is sure, the d1-core never makes it too much or too spectacular, it relies first on exactness.", haute fidélité
"...like never before... Diapason d'Or golden prize." Diapason
"The Totaladc d1-core creates highly detailed sound which, like vinyl compared to digital files,
is naturally fluid and smooth to the ear, reproducing the three-dimensional spaces.", CODE magazine

Damping feet option:

Custom damping feet are available as an option for a nice sound quality improvement.
The optional damping feet are 15.5mm high whereas the stock feet are 13.5mm high, so the product gets 2mm higher.

1KHz -120dBFs sinewave 20Hz-22KHz spectrum:

The measurement is done on the RCA output with USB as source, from a standard computer plugged on mains, in "display OFF" mode.
The noise floor is very low.
