In a word - NO - measurements do not matter (so long as they're not terrible).
The only thing that matters is how the components sound, which typically / often is not consistent with the measurements.
The most important consideration is how well the components match / synergize with one another - are the electrical requirements of the speakers provided by the various components, and do the sound qualities of the speakers harmonize well with the components and do they fulfill your preferences in sound quality.
Which is why... sticking with the components offered by a particular manufacturer and the components the manufacturer suggests - typically produce the best sound quality (e.g. ARC preamp with ARC amp, McIntosh preamp with McIntosh amp, Magnepan speakers with Bryston electronics, Harbeth speakers with Hegel electronics, etc., etc.). If you do so - you'll be far more pleased with the sound you hear... and far less frustrated in assembling your system.
