Amazing value USB /SPDIF interface for DAC
Me and my friend bought this module when catching a promo. Until that moment I was using GUSTARD U12 32Bit / 384KHz USB XMOS DSD. I just build a small thick walled (4mm) alu chassis for this module, and served the power supply voltage separated from the USB cable, by using an audiophonics usb separator cable, and an external no-fancy well made smps wall power supply. The module need some serious burn in , be aware. Once this settled, the sound quality is top notch.
First of all, what pleased me was the resolution, control and the depth of the lowest register! Also, the dynamics rendering is superb. Soundstage is very correctly rendered, with no exaggeration, you could detect easily instruments locations (separation of sound sources is good), with a very good sense of depth. The timbres of acoustic instruments are reproduced faithfully, a must in classical music auditions. The attack on aggressive well mastered tracks (percussion instruments, or plucked classical instruments) is as should be. Human voices sound natural, without being harsh or on the analytical side. Also, large scale recordings ( big classical orchestras) are a joy to listen.
Just a brief example: the first track on Erato CD 'Joyce DiDonato - 2014 - Stella di Napoli' it's enough to check for making an idea on how Hecate LT knows how to shine. This Hecate LT thrashed away the good old Gustrad, which was a good companion.
Be aware, this Hecate LT works very well on I2S, as me and my friend tested it with top DAC, if wanted to implement inside the DAC chassis.
If wanted just for the SPDIF use, buy the finished in chassis version, it worth the difference :)
For Daphile/ Roon users: Hecate LT works like a charm on Linux based audio players without drivers.
Highly recommended!!!

Great product.
I am a tube amplifier builder. But now I build a tube DAC. This product very very good for USB connection. The ARMATURE HECATE XCORE 208 is better but in the middle frekvencies the LT better.

Quality Construction
Used this board to replace a DDDAC 1543 mkII failed PCM2707 USB-I2S board.

I connected it via I2S
(Hecate-DDDAC)
GND-GND, BCLK-BCK, LRCLK-FS DATA-DATA

As long as I select 44.11kHz output from the PC, my DDDAC 1543mkII sings nicely :)
