NAD's have a better fit and finish now than ever before. The components they use (resistors, capacitors, switches etc.) are also getting better with every generation. The quality has actually improved since production was shifted from Taiwan to China several years ago. The older say, pre 1994 models are a bit crude but a good value used for starter sustems. Tweakers love them because they are easy to dissamble and modify etc. NAD mods bear a lot of fruit sonically because the op amps and capacitors they used in the past were horrible. The 160 or 162 preamps are excellent for the $. The matching 270 and 272 power amps are a fine bargain new and used.
