Johnnyb53, there is a Parasound Halo A23 for sale on here at $50 less than original list for a four year old unit. Does that seem reasonable?
I saw that A-gon listing and it had me scratching my head. You can get a brand new Halo A23 from AudioAdvisor for $995 with free shipping, probably no sales tax, and a 5-year factory warranty. When you add the A-gon listing’s $944 plus the vendor’s shipping ($37) for $981 total for a 4-yr-old unit, the $14 saving hardly justifies the risk differential.
I’d go for AudioAdvisor or any authorized dealer’s new-with-warranty Parasound Halo A23 over the A-gon listing, no question.
If the 4-yr-old unit was $795, then maybe.
