I have a pair of paradigm studio 20 v 2s that I am trying to get the best sound out of that I can. Right now I run them thru a yamaha surround reciever and JVC dvd player. Should I first look to replace the amp or the source? Any ideas on either? I have looked at NAD and Creek for amps (integrated) and NAD and Cambridge for source. Also am on a tight budget, probably couldn't look at more than 300 for either, would be great to find either for under 200 if possible, will consider used. is this possible? Anyway, lots of questions, any help is great appreciated. If it matters, the majority of my listening is classical. Thanks.
