My question here is about the upgrade path I'm planning. I currently run Klipsch Icon W series for front and center with Quintet surrounds. They stopped making them and I'm thinking about getting a full set of Reference 2 series with either towers or bookshelfs. I'm not sure if the Reference 2's are a good upgrade, whether towers or bookshelves for fronts or what size would be a good match with my LPA-1 @ 125×5 and 50×2. Any feedback would be greatly appreciated. Thanks in advance for your time.
