In my opinion a good amp is a good amp regardless of when it was made, same with preamps etc, they may need a service, such as recapping Naim etc, but it is all on how it sounds.
Older higher end or newer mid-fi...better bargain?
Say you have $1500 to spend on a 2 channel pre amp/power amp combo or integrated amp: Would you opt for an older, for example, NAIM system (e.g. 62/hi-cap/140 c. mid 90s) or a newer, say CREEK 5350se integrated...or what? Where is the most performance for $1500 to be had? I listen to CDs, SACDs, DVD-As, and LPs.
