I´d like to share a different perspective on this matter.
First of all, if I personally think that the noise level is a problem, it doesn´t make me feel better that others have the same issue.
And yes, I have other analog gear, like a Vermona perfourmer and an Eurorack modular, or a Dark Energy. So I know that analog synths can be peculiar when it comes to noise. Still, I would expect a difference between the perfourmer and the Voyager.
A lot depends on customers´ expectations towards the product they purchase. Moog create a very high expectation by positioning the Voyager as a product of excellence, and they charge for such an excellent product. If the product doesn´t meet this expectation, why should customers not have the right to complain?
Actually, Moog should be interested in customers giving their honest feedback instead of shutting up because they might be considered to be hypochondriacs or the like
Only if they get feedback they can make their product better.
Now there are quite a bunch of Voyager owners expressing that the noise level is a problem for them - so it´s not a solitary opinion, this is important to me! - whereas Moog would say, the noise level is a normal thing, especially for analog synths.
With whom should a Voyager owner who doesn't care about the noise problem solidarize with? With other customers, or with the producer? Might well be that the one making a bad decision here could face a problem himself one day, and maybe would be glad if Moog would be listening and if he got support from other customers.
There was a time when a crappy Chinese keyboard was built into some Voyagers... Customer´s were very unhappy with this afaik. Why did Moog do this? Did they think a crappy keyboard would make customers more happy than the quality Fatar keyboard? I can only guess, and my guess would be that they did it to cut cost (I think they were replacing a lot of keyboards at that time, carried out at their expense).
