Need help with ProAc Response OneSC

Anyone has any comments about ProAc Response OneSC? I am going to purchase one soon, but have not had a chance to compare with other speakers in the price range, ie. Totem model one sig. Anyone has done any comparisons with other speakers? I like speakers with good image/soundstage and listen to variety of music. I am going to drive them with a (budget) integrated amplifier, again, I need some help. Which reasonable priced amp would be able to drive the Response One? Thanks.
