The idea of tubes being holographic is a broad generalization and is highly specific to the individual component and the result of the whole system. All components matter. .
Yes, keep them for a while, you need at least 200 hours on it before the component starts sounding like it should (usually 400 or more to fully break in)... keep it going when you are awake. But definitely return it if it doesn’t do exactly what you want. In that case you got a chance to really learn about a component in detail. To me it takes a couple weeks of listening to music (not to the system sound) to understand what a component sounds like.
.
The end result you want is a perfectly reasonable one. But it is going to take a lot of work... reading, listening at dealers, and experimenting. The sound you are looking for is balancing a system on a knife edge of tonal balance to have enough high end detail but not be harsh and really quite background. The most holographic systems I have heard were based on Wilson speakers... although they by no means are the only speakers good at it. But... it is every piece of equipment and the interconnects that will get you where you want to go.
