I would not use an Adcom 5800 with any speaker of a vented design. I have no experience with any of the other devices mentioned. Sean

What would you choose among these to amp?
I am buying a new amplification set for my system, and I now have my options narrowed to basically four:
Roksan kandy integrated (1100 dollars)
Adcom 5800 + Rotel RC972 preamp (1000)
Adcom 7000 integrated (1000)
Marantz SR-18 receiver (900)
Considering the closest upgrade I have in mind is a subwoofer, and I will use the amp to drive a pair of JBL S310II, mainly for music usage, what would be the recommendation?
