Tarquinh:
As in not needing to upgrade any more, nor tweak, because they're happy with what they've got?
I've one upgrade to go, i.e. an amp change, but keep putting it on hold since I'm happy with the sound, to the point where if I try to listen analytically to the system, rather than the music, I can't.
I think you're actually asking two different questions here Tarquin.
Yes I am very happy with my Hi-Fi, I stick it on when I get home from work most days, and just sit there listening to it. But, I also know that it was built to a budget, and that when the time comes, buying an amp in the £1,000/£1,500 area will boost my system and my enjoyment even further.
