Wadia 9 power supply: 3 separately regulated power supply stages with independent transformers.
The input voltage can be switched without the need to take off the cover.
Hi, can you tell me what its worth, the Wadia 9 decoding computer with the power supply, thanks, I appreciate your help
Hi, for a 9 in good condition I would say about 3500 euro.
Hi Christiaan,
I am searching for wadia9/10 full set in good shape, unfortunately they are impossible to find now a days, and who has is won’t let it go. There were some offers recently asking 8,000€ plus
Alas, 10 or so years ago I would see them relatively often but these days, they are really rare. I wouldn’t pay 8k for the pair, though.
Can the voltage be changed inside if purchased overseas to work in the US?
Quite possibly, but I’m not sure. What will surely work is using an external step-up transformer but there’s a chance that this will lead to a different sound. Although, I have done the inverse (a step-down transformer) with two Philips CD880’s, one from the US (110V), and one from the Netherlands and although there were differences, both sounded great.
wadia 7 and 9 are user main voltage selectable, not need open unit,
Thanks for confirming, Alberto.
Hi Alberto,
Do you know if the output voltage of Wadia can be changed too? its set at 13 dBV which is about 4.6 V which is way abouve most preamplifier input voltages.
Any idea?
Thanks,
Karl
Hello
yes can change
The voltage can be adjusted via internal switches from 0.3V to 4.25V to match system sensitivity.
I think not all wadia 9 versions have switches!!! need try.
Hi Alberto,
Thanks for your replay. Now I have to search the web to see if there is any information on this. Do you know how this can be done? The switches are located on output stages?
Thanks,
Karl
Hi Karl, I’ve not owned a Wadia 9 but if it’s anything like the other Wadias that I did own, then you’d see a row of micro-switches that select resistors in and out of the signal path. Looking at the W9 pictures that I have, I see no such thing, nor any other obvious switches. However, they could potentially be located underneath the PCB. In any case, the attenuation is in the analog domain, and this will need to be located in the output stage.
Dear Christiaan,
Thanks for the reply and the check.
Another point/question regarding choosing a DAC and a preamplifier: most DACs have an output voltage of about 1.8 V upwards to 6 V or so, on the other side many preamplifiers have input voltage sensitivities of no more than 400-500 mV at their line inputs. Is this not going to lead to some clipping or over saturating the preamp? Is there any standardization?
Thanks,
Karl
