Hi zdr,

Are you still selling LDR kits or just AIO PCBs?
I would be very interested in buying one.

Cheers,

xbitwise

Default Working well

Hi, a quick note to report back on my experience after a couple of weeks with the VxD volume controller v 2.6 in my main system.

Output is to Peter Daniel Gainclone amplifier, input is from a Allo Kali / Piano2.1 DAC fed by a 320 kbs Spotify stream. Speakers are KEF LS50's.

Safe to say that the sound I'm getting from this set-up is the best I have been able to obtain so far. It is very airy and transparent with silky tight deep bass and beautiful rendition of instruments and voices. I can listen for hours on end working or doing other things and really liking the enveloping effect of the music. When sitting close to the speakers (they are monitors after all), its almost like having a pair of very good headphones on and the spaciousness of the sound is fantastic.

The user interface, remote control and calibration of the LDR's are also very cool.

So, thank you to all involved (especially Neb) in the creation, tuning and optimisation of this great volume controller :-)

Very glad you like it. You should move to the next level and replace gainclone with Roender’s FC100.

Does this amp use a lot of electricity when idle / running ? I've tried to avoid amps that heat the room while idle :-)

RMI-FC100 is class A until 8W so there is some heat dissipated, but it can be biased for less dissipation. Better to ask for details in the FC100 thread.

zdr,

Purchased your v2.2z version board recently and tried hooking it up today. I am getting a error 20. According to the trouble shooting section, this is related to the power supply voltages. After double checking that the proper voltages are getting to the controller board connectors, I was wondering if I might have missed a jumper on this new board that incorporates locations for it's own power supply components?
Is that the problem or is there anything else I should be looking for?

Regards,

Roy

There are no jumpers to be set, board is backwards compatible out of the box. Error 20 means relay power failure or ldr failure (resistance > 200 ohm)
