solid state integrateds that will hold their value

I HATE losing a lot of $$$ when the bug hits me to try something new so I like to purchase gear that is not only reliable but holds its value well long term (and of course sounds good!).

Two on my short list are:

Jeff Rowland Concentra I or II
YBA Passion

Mac's also seem to remain pretty stable in pricing but i have actually never HEARD one. Comments/comparisons of sound etc welcome.

Thanks

Jeff
