Here's an anecdote:
My mom has had the Bose speaker system for years. I purchased and set up a low-end hifi audiophile system ($3,000) for her at her home, and she is amazed. She loves it and is listening to music and enjoying it like never before. She is hearing things in the recordings that she never heard before.
It's a rather simple system: 20 year old $1,000 bookshelf speakers (Revel Performa M20), a 10-15 year old $1,000 solid state Musical Fidelity integrated amplifier, and a 15-20 year old $1,000 Musical Fidelity CD/DAC. I connected everything using basic 14G OFC cables.
If you had trouble getting great sound out of your system, it was probably due to mis-matching of components. There's a world of wisdom in these forums that can help you build a great system!
