Buying used vs new?

A good piece is a good piece and buying used can save you a fortune for sure, hope it works out for you, also one thing to consider is that the component is broken in with a used piece which can sometimes take hundreds of hours before it sounds correct.

I’ve ALWAYS bought stuff used. Why pay the full freight?

If it’s a POS, then half off is not a good deal.

if it's something without functionality you want, then half off is not a good deal. 

Because it's impossible to differentiate between used and abused.

For reputable equipment always buy used if available in good condition. Saves you the 6+ months running in. Dealer amps and speakers likely current models and unlikely to be abused. Not like cars.
