Having run Ruark Epilogue R's as mains for a while, I finally tracked down a pair of Prelude R's for mains so I could move the Epilogues to the rear where they belong. Now, the Epilogues are fantastic little speakers and quite charmed me. On firing up the Preludes, I was underwhelmed but decided I would grow to love them. The lacked the punchy dynamics of the Epilogue. The clarity and richness was gone but the overall sound was warmer and easier. The other day I picked up a copy of Stars by Simply Red in Tesco for £7. Had it years ago and lost it. Came home, played it. nice. Now, I have recently decided to sell the house and have had to remove some AV gear to make the place look better, which involved going back to stereo with the Epilogues as mains. I put on 'Stars' and low and behold, I hear things I have never heard before. Dammit all to hell. Why do they sound better? I can't accept it, they were half the price or less. I'm now thinking of ditching the Preludes, getting another pair of Epilogue R's and investing in a fine Sub for the bits they really can't manage. I love those Preludes though. Damn you God for making me think this way.
