To be honest with you, I always go with the less expensive solution if the difference in quality is insignificant to me. I never considered the HD amps any better than the old PDX just because of the price -sometimes priced at twice the cost of a comparable PDX. The new PDX apparently solved all the nagging issues (mostly noise) of the old version and then improved in many others (even better heat resistance) so to me there is no reason for getting the HD amps over the new PDX if price is the priority.

However, I do not like to give opinion of what sounds better than the other as each person takes car audio very differently. I'm perfectly happy with a $140 DLS component set, but others must have a set of Exotars or they go insane. The same applies to the HD and the PDX...
