That's kinda-sorta true. A better statement would be that the tubes which provide the most gain, or "amplification" will affect the sound the most. A tube preamp is always near the top of the chain, but the phono tubes affect the sound a bit more than the linestage tubes in the same preamp, while the linestage tubes affect sonics more than would the cathode followers (if present) in the same preamp. Put simply, it's all about gain. Tube CD players or those Magnum Dynalab tuners that "gots toobze" (yes, they really are THAT important in the Magnum's overall sound) use tubes in a zero gain buffer amp circuit; changing these tubes will make very little difference. In a tube amp, the phase splitter tube needs to be electrically sound and section balanced but changes here will also not be earth shattering. The 1st tube/voltage amp in a tube amp is about on par with linestage tubes as far as benefits from premium tubes-- pretty significant; more significant than the output tubes themselves. The main thing is that to change line or phono tubes and install good NOS is generally much cheaper than buying matched quads of NOS output tubes-- the cost/benefit ratio leans to spending on preamp tubes rather than output tubes as giving you much more bang for the buck. When you do go for those NOS preamp tubes, save some $ and get good 1950s and 1960s US tubes by RCA, TungSol, and Raytheon. They are as good or better than Telefunken and late production Mullard & Amperex for less than 1/2 the $.
