To summarize from one perspective, money does not guarantee a clean signal
for the transmitter.
One can ruin the signal of expensive radios by wrong tuning set.
And, some expensive radios simply are worse than some less costly radios.
Some radios claim to have super clean parts in the amplifier chain.
But that only reproduces the poor and wide signal the oscillator design
produces.
Real clean transmitters are the next step in ham radio equipment
development.
Many receivers are pretty good already.
Only some of them cost a lot of money.
