1) I won’t hear the difference
If you care about music, you will almost certainly very quickly pick up on the abilities of a better system.
2) A good system costs a fortune
if you want find the best hifi systems, like speakers and other things, then you have to go for the online. It is true that the very best systems can cost many many thousands of pounds, a good system can be had for around £3000. Look for second hand equipment, like
cd player and other hifi systems with low hours of use and specialist warranties (surf the net, I’ve discovered Martin Anderson Hi-Fi Specialists for myself). You will be able to afford a much better quality gear if you refrain from buying brand new stuff.
3) Technology is moving so quickly that anything I buy today will be out of date by next year
The driving force behind the consumer electronics market is always new technology. By buying a good Hi-Fi system you are sidestepping these issues. CD will be with us for a long time to come-remember, LPs are still available 20 years after the introduction of CD. Quality lasts.
