I've got a pair of Wharfedale Pacific Evo 20s running off a Pioneer a445 bi-wired, I'm looking for a new amplifier as this one is starting to go a bit dodgy. I was looking at both new and 2nd hand amplifiers in the £300 ish range I was considering either the Marantz pm6005, the cyrus 6vs2 or a variety of rotels. I'd quite like an amplifier with a remote control and bi-wirable. What do you think or are there any other amplifiers I should consider?
