What are you guys using?

Line-level audio run from the primary system (via 75-ohm RG6/U) room-2
output to a 25 year old Kenwood 35 wpc integrated amp (KA-3500)
feeding a pair of Yamaha bookshelf speakers.

Feeding the main system is a pair of Sony CDP-400 changers
configured for random-play alternating between players for
no delay between songs. 700 discs at approx 10 songs per
for a 7000 song random play catalog (30% jazz, 70% rock).
