I use the toggle switch because it is soldered directly to the PCB - so no wires

The other switches look nice but need to be fastened to the front panel & then require flying wires which is messy & a double process.

At the moment everything is on the PCB so it just slides in & then the panels go on. Good for service too so the whole thing just slides out & can be operated/tested/modded without the case.

The other option is just eliminate the switch & have remote power on/off. It would mean it would be in standby & using power even when switched off though.

Remote on/off with 12v trigger out would be excellent!

Nice work Clay

The audio circuitry is very similar to the Klein but all the digital supplies have an extra regulation stage so there is better isolation between analogue & digital supply lines. Also there is an extra filter called "super slow roll off" which is rather interesting.
Because the filters can be switched via the remote it is much easier to hear the differences. Sit it the sweet spot, crank it up a bit & flick through the filter settings. With DSD you have 64 128 & 256 - no 512 until the AK4497. Not a big deal as I've yet to find much DSD 512 content. With DSD there is also bypass mode which skirts around quite a bit of internal circuitry within in DAC chip itself. We spent a lot of time on the muting to eliminate pops/ticks but you still get the odd one say if you jump mid stream on a DSD track to a PCM track.
The good thing is it is easy to swap the chip so if we improve the software down the track I can always send out upgraded chips. Beginning to feel like Ted Smith now ha ha.
Yes I agree the toggle switch looks a bit out of place so maybe remote power on & 12v sense out - good idea todagt
The output is fixed at 2v RMS but as we have software control it would be possible to utilise the DAC's internal digital attenuator.
We may make a variable output version available with a different remote if there is enough interest. A little bit risky though as the DSD bypass mode is on the remote so you could go from low level to max with one click, anyway something to think about.

Looks nice! Will it come with balanced outputs?

No balanced out on this one but we may make it an option on the bigger version.

OK I might need to get a toggle switch vote.
