I think I am really missing something here without a $20,000 system.
I am a really big fan of hers. What is it about this recording, which I do not own...yet? I have always found her work enjoyable and well recorded in a new age sort of way.
It sounds like there is much complexity and flavour barely heard that would come out with a better system. But I guess that is probably the case with any well recorded material.
That is usually the case with most music other than some old mono releases. It should also be noted that some of the new older RCA Red Seal 3 channel tapes transfered to SACD are remarkable for how much the recording engineers captured. Miles Davis' Kind of Blue reissued and discussed at great length in the this month's "Phile" by John Marks is a perfect example. The other side of this is the reissued Cd of Birth of Cool, a mono recording which is more about content study than recording quality. If you choose to upgrade remember their is the law of diminishing returns that takes place as much more money makes smaller incremental improvements. A good dealer can save you much time and money in this regard. Take music with you and see what you find out. Remember, you do not have to buy the first few times you go out to audition new gear. This is a quest not a one night stand. Good luck.
