The Katana in simple words, is without doubt the BEST I2S DAC for Raspberry PI.
For 3 simple reasons:
– The DAC is without doubt one of Audiophile’s all time favourites, the Ess9038q2m.
And it’s in Master mode! This means that it’s immune to Raspberry PI’s jitter.
– It can be used in different power settings, so it can be fed with 3 different power supplies
for the best performance and Signal\Noise ratio.
– It has a class A output stage. Which is not only very chich, but also quite effective.
Why we like it:
– No compromise design. Here Allo just went for the best
– It has hardware Volume Control
– It can handle DoP
– It can be fed from 1 to 3 indepent power supplies
What can be improved:
– As all advanced piece of equipment, it’s not ideal for beginners, as you need to set jumpers and
use different power supplies to get the best out of it.
UPDATED 1.2 VERSION
This is the Katana 1.2 Version, the definitive Katana experience. After the initial sale, Allo listened to the community feedbacks and made some changes which resulted in:
– Improved THD+N
– Removal of listening fatigue (Allo’s words)
– Improvement in the dual rails feeding the opamps
- RPI B
- RPI B+
- Possibility to wire balanced XLR output
- Board mounted RCA output connectors
- ESS SABRE 9038Q2M DAC chip
- Can handle DoP
- Super Capacitors and Thin film IR in signal path
- Ultra low jitter clocks from NDK NZ2520SDA
- Lowest jitter ever (390fs)
- 6 class A opamps in output stage
- Each board is hand-trimmed for DC offset
- THD+N (1Khz, 0 dbfs, a weighted) at -112.75
Due to the fact that every Katana is custom programmed and fine-tuned by hand, production is slow. Please note that it can take up to a week to ship your unit.
