Hey guys, My current main system is an HK 510/Parasound 855a driving 4 Wharfedale Emerald 97 towers and a Yamaha CC...also a JBL PB10 sub. 2 channel sources include an HK CDR20 and a JVC 70BK DVD player. What's the cleanest way to incorporate a Stereo PreAmp into an existing HT? Sorry if this is overworked material. Thanks a bunch.
