Although the implementation is proprietary, in essence, the Tambaqui is a bitstream DAC. Historically, I have always preferred multibit DACs or NOS DACs over bitstream variants. But, as the listening tests would soon reveal, the Tambaqui threads a unique sonic path.
In addition to I2S, S/PDIF coax, AES/EBU, TOSlink, and USB, the Tambaqui is also RoonReady, and it offers an RJ45 network input that can be used to stream Roon signals to the unit. Inside is a full-fledged endpoint/network renderer that makes external streamers superfluous. The analog outputs are available only on XLR but there’s also a headphone output on the rear that can be controlled separately from the Mola-Mola remote control software for iOS and Android that can run on a phone or tablet.
The Tambaqui can process PCM up to 384kHz/32 bits (>192kHz and >24 bits via USB and Roon only) and DoP and Native DSD up to quad speed (USB and Roon only).
While the Tambaqui is originally designed to be used with an analog preamp (the Makua), it does contain a digital volume control that works via the supplied standard Apple IR remote control or the excellent iOS/Android app (see image above). The Apple remote control works with RC5 code, and as such, any other likewise-coded remote control for a similar device should also work.
With its volume control enabled, the volume can be controlled directly from within the Roon interface. Incidentally, the Tambaqui’s 4 front panel buttons can be freely assigned to any function from the app. For instance, they could be representing 4 inputs or volume buttons, an input toggle, and another function.
