No matter if you are into analogue (e.g. turntable) or digital (compact discs, locally stored music files or online streaming). Spend more money on the source!
Why? In the case of a turntable it is very obvious that a good turntable with a good cartridge will technically get the most out of your record’s groove, as it picks up and reads the information more accurately. Whatever gets lost here will never reach your ears – no matter what amplifier or loudspeakers you have.
In the case of a digital source the data has to be loaded, read, converted properly and thoroughly to an ‘analogue’ music signal. There are many variables that can have a negative impact on the audio signal, such as a poor circuitry or the quality of the D/A (digital-analogue) converter chipset. Again, whatever gets lost in this process will never reach your ears.
If you spend 30-40% on a good source component and 30% on amplification, it will always give you a great result. Maybe some will say that the shortcoming in such a system is the loudspeaker, but the above truly proves the importance of the source.
