I can get the Boston Acoustic MCS100 MDNT 5.1 speakers at Dakmart with a Denon AVR590 reciever for $384 delivered. Both are refurbished. The Denon DHT590BA (Denon AVR590 paired with Boston Acoustics MCS90 speakers) new would cost me $650 after tax. Is the difference in speaker level and the refurbished issue worth the savings? Thanks for any help.
