I'm a live guy not a recording expert but immediately spotted a flaw in you reasoning, Valves/Tubes are are almost always used to introduce 'colour' but you want "very clean vocal records" which implies you don't want/need 'colour'. So I'd say "no it is not necessary for the kind of vocal recording you say you want".

Also, how well is your room treated?

Mr. Sam you said that ''colour '' . Can you explain what kind of colour is it or what does colour mean ?

For vocal recording the most important things are (in order of importance):

1. A great vocal performance
2. A well treated room
3. A microphone that suits the voice

Mic preamps and other electronic gear are way down the list of importance and you'll probably find that the mic preamp in your audio interface will work fine. I'd only start worrying about preamps once you had acoustically treated your room and invested in a good microphone - and only then if there was a problem like noise or lack of headroom with my current preamp.

What James says.

However, since you ask.

A modern preamp used well within its headroom characteristics (the range of gain levels it's expected to receive and output) is gonna be very "transparent", and you will find little difference, if any, between run-of-the-mill preamps like the ones in computer audio interfaces and much more expensive ones.

Noise and distortion - i.e. changes in the "shape" of the voltage you send in input via the microphone - will be low, and the signal will come out pretty much as it comes out of the microphone (only, of course at higher voltage level, that is - amplified). Modern preamps, even budget, are very hi-fi (i.e. the output is very true to the input signal) when used sensibly.

However, if you move towards and beyond the edges of the preamp's expected performance envelope (for example - cranking the gain to the top while using a microphone which emits a fat signal level, overdriving some part of the circuit) - all preamps will progressively distort and add noise..

This is called "color", and it's quite different for different preamps, because you're basically using the electronic design outside its expected operating parameters, and all designs will react in their own ways. Some of the designs will color the signal in a way that it (subjectively) becomes crappy; others, will actually add something that most people like (a bit like some cranked guitar amp distorts the guitar signal but still produces a sound which people like).

Guess what: the "famous" (and famously expensive) preamps are the ones which color the signal in a nice way: ISA, APIs, Daking etc.. Whereas most (not all) cheaper preamps, when used outside the expected parameters (e.g. cranked), will color (i.e. distort) the signal it in a not so nice way.

Keep in mind that most preamps producers (especially the uber-expensive) try very hard to keep the signal unchanged at all times - which is a difficult and expensive thing to do! Millennia, Grace and other manufacturers are known for their extreme transparency and cleanliness (i.e. lack of distortion and noise).

Note also that it's not so that all tube preamps color nicely and all solid state don't: there's all kinds in both classes.

So it makes little sense to buy an expensive preamp and use it within parameters: you buy it for the "color" that it provides when cranked.

This in turn comes with a set of issues (you usually get a very hot signal doing that, which you need to pad down lest you exceed the headroom of the A/D converters that follow... unless of course you buy very expensive A/D converters with lots of headroom - and so the money flows.. :-D).

These days, you can well record very hi-fi and add the pleasant distortion after the fact via plugins. It's much easier, cheaper, and generally gives the same results - nobody can notice the difference if they don't know already..

However, hardware is fun, and that's the main reason for having it. The secondary reason is that it allows you to hear the "final" signal in your headphones when you record, that may be a nice thing.
