Been playing recently, and have come to the conclusion that most audiophile speak is rubbish. I can tell speakers apart. Beyond that, assuming that the product is being used as intended at a suitable volume, there is really not much in it. CD players all sound the same - any difference is distortion or possibly matching issues. Record players do differ but are less accurate than CD players , given the same material. Amplifiers are identical until they clip - therefore as long as there is enough power, which need not be much, you are fine. I will not even discuss cables.
Such a revelation leads me to the following thoughts.
1. Spend your money on speakers - great big ones!
2. Spend anything you have left on your music - get decent recordings - that makes more difference than anything else apart from 1!
3. All the rest is frippery. As long as you recognise it as such it is perfectly acceptable!
If you disagree, do an A/B/X trial. That means listening to two systems which you can do for as long as you like knowing which is which. Then get a friend to play one of them again. You can compare this to A or B as you like. If you can reliably tell the difference, then there is one. If you can't... (Clearly flat set controls , same volume etc)
Try it with amplifiers!
