Reflektor-D builds

[Flikoman]

Does anyone have a spare Reflektor-D PCB or whole kit or maybe assembled board for sale? 🙂

Salas Reflektor-D can reach 600mA 5V?

 

[Salas]

Yes it can

 

[merlin el mago]

What value for R1 0.8 ohms?

 

[Salas]

Sounds like a good value to try

 

[merlin el mago]

Thanks.

I'm now powering my Simple DSD Modulator https://www.diyaudio.com/community/threads/simple-dsd-modulator-for-dsc2.370177/ to convert PCM to DSD files on the fly with Ubib. Do you think will sound better with Reflektor-D?

 

[Salas]

Can't tell. Haven't played with that FPGA module. Some digital like Ref-D very much some are as happy with Ubib. Just try.

 

[merlin el mago]

Work done! Time to connect and listen.

 

[merlin el mago]

Reflektor-D seems to have a lot of less noise floor for digital devices compared vs UBiB.

 

[Salas]

REF-D is specialized. Some digital devices highlight that some other are not so sensitive.

 

[merlin el mago]

I will try again UBiB with R9 1K mod for high current loads.

Salas what's the max. & min. capacitance value for C2 without compromising stability & sound quality?

 

[Salas]

For Ubib?

 

[merlin el mago]

Isn't C2 1000uF for Reflektor-D?

 

[Salas]

For REF-D 1000uF-2200uF is a tested good range. For Ubib 100uF-1000uF.

 

[Salas]

Happens the Vref filter capacitor is named C2 in both

 

[merlin el mago]

That's great for Reflektor-D now 1.000uF Nichicon KZ but I have 2200 BG, & I want to compare vs UBiB that's full BG....

 

[merlin el mago]

The more capacitance better because more filtered?

 

[Salas]

Depends on parasitic factors of larger caps too. Their quality. In general 1000uF is large enough for good subsonic range filtering in this kind of regs.
