Yes, but for now I'll trade the JLSounds' DSD256 and isolation/reclocking for the Amenero's DSD512. Now that the DSD genie is out of the bottle I'm hoping that DSD512 becomes more common while I explore the low pass filter decoding options a little with my current projects.

I havent got Rays little pcb connected up to my JLSounds board yet, but i did try an Amanero connected up to a simple lpf. Using windows server 2012 and JRiver to upsample pcm to 2 x Dop, i gotta admit it sounds pretty good. Couldnt get native dsd to work, but its showing up as dsd output.
Nice.

It's been a bit quiet of late so a couple of updates as I've received a few PMs.
Balanced flip-flop PCB: I've received ten boards and have made one up. The relay and LED circuits function correctly but I've not yet listened to the results as I haven't had time to complete the buffer I plan to use with it but I'm hoping to do that in the next week or so.
The revised single-ended PCBs haven't arrived from HongKong yet.
I'm happy to sell the spare boards but I'm not happy to commit to taking any money until I am satisfied that the boards function correctly.
In the meantime, in true British tradition, I'll organise a queue...
I've listed below those who I think have expressed an interest. If you want to join the queue just cut and paste the latest list into a new post and add your own requirements at the end.
All being well I will have 9 balanced and 8 single-ended boards available (though a reorder is a possibility). Cost will be £3 per flip-flop board and £2 per single ended board, plus shipping at cost.
Anyway, form an orderly queue here:

I've managed to get the JL board combined with Ray's original mute board working with daphile converting pcm to dsd. Sounds better than the amanero version , as youd expect as JL board has two separate regs for usb and clock, and I believe linux is superior to windows for audio.
Mute board works well, no pops.
Now ive got a "no-dac"system to compare to the "no-usb" system.

Hmm.. i'm not sure if i'm on the right train
Could anybody please give a short summary what the boards functional include or what are the difference ?
Flip Flop, Single - Ended, Balanced ?
Many thanks in advance
Regards
Marcus
There's lots of detail in the thread about what these boards do but to summarise:
The boards are intended for DSD playback only and use a simple low-pass filter to extract the analogue signal from the DSD stream.
In addition to the LP filter the boards also include a mute circuit that addresses the pops/clicks than can arise with this approach to DSD playback. Finally, there is a circuit that lights an LED when DSD data is received.
The PCB is designed to fit onto the header pins of the JLSounds I2SoverUSB board which, with the right computer feeding it, is capable of DSD256. With some creativity the PCBs could be used with other USB audio boards but the JLSounds one works very well.
The single-ended PCB feeds the DSD directly into a single low pass filter so the derived analogue signal is single-ended.
The flip-flop PCB feeds the DSD into a flip-flop integrated circuit which produces differential digital outputs; these can be passed through the dual (per channel) onboard LP filters to derive balanced analogue signals or, alternatively, the differential digital signals could be passed through TVCs.
You'll need to consider other factors such as what you do with the derived analogue signal, such as whether to use a buffer. Also consider where/how you're going to get your DSD data.
Hope that helps.

Gosh, this is proving a lot more popular than I anticipated and I wasn't expecting to run a group buy type exercise. Looks like I may have to order some extra boards if it all works out.
