Is it all worth it?

So this week I re-foamed a pair of Boston Acoustics a40 series ii speakers I bought 30 years ago for not very much at all by audiophile standards. Put them in my 12x12 sunroom running of my main system which has very good source and amplification and these things are blowing me away. You could find a pair online or at your local thrift shop for around $50. Why bother spending the big bucks?   Really makes one think.
