Used Rogue 66 and a used Bryston 4B-ST can be bought for less than 2K with change to spare. You might even be able to find a "Magnum version" of the 66 within your price bracket. The Rogue will warm up the Bryston amp nicely and the Bryston amp will provide you with the current you will need to run those 3.5's like they should be run!
Not too sure about the 4 ohm rating on the Plinius 8200 but its 175 w/ch @ 8 ohms might be a good choice for an integrated amp...
