Happy New Year!

I have my project almost over. I have a prototipo mounted in a wooden box. It's a buffalo II DAC with selectable output stage between tube and legato v.3. This change is with a switch. I have used panasonic tq2 relays to make the change.

The relays off (no power) give way to LEGATO. The signal path between dac and legato is 4cm.

The relays on (with power) give way to tube-i-Zator. The signal path is 8-10 cm.

At the moment I have a little more length in the cables and they are somewhat messy, until the final place in the box. All signal cables are silver.

I have used shunt regulators for all power supplies. 2X tridents and a shunt regulator for the clock. Some Russian PIO capacitors and bypass ft3. When placed in the final box I put Mundorf silver in oil in output valves and some resistance Texas Instruments.

The DAC is controlled by arduino. I'm yet to put a usb-i2s interfece. Russ / Brian for when we have the usb-i2s xmos?. At the moment it is connected by toslink. My source is a MacMini.

The sound is fantastic. At the moment I do not find differences with the version without relays
The pictures are made with a mobile phone.

Sorry for my bad English.
