I have Klipsch Rf-7 fronts, RF-5 rears in my home theater system, and also a set of Synergy SF-1 in my bedroom system. It is true that Klipsch speakers can run bright, but I have found in demoing multiple systems over past few months that the "brightness" factor was direct related to what components were used. The speakers were not bright mated with nakamichi, denon and cary audio, and were bright with a rotel rc-1070 stereo pre-amp, rcd-1072 cd player & 1080 amp. The rotel pre-amp & amp were new, & I only had the rotel gear for 5 days, so the components may not have had time to break in. I have also demoed numerous B&W speakers, mated with rotel, lexicon, mcintosh, classe & cary audio components. The B&W & mcintosh combo was on of the best I have ever heard (sorry I don't recall specific components - B&W's were one of the 800 series speakers), but I was not at all disappointed coming home & listening to my system. The B&W/mcintosh combo did sound better, but at a price point exponentially beyond what I have in my system.
My synergy speakers sound fine, particularly for what I paid for them, but are not in the same class as the reference class speakers. My current components are a Denon 2805 receiver & 2910 DVD, and I'm upgrading to seperates. The 2805 is capable of driving the RF-7 & RF-5 (waiting on my RC-7 center speaker to arrive), but it's not capable of driving them to their full potential. Current favorite is Cary Audio Cinema 6 & Cinema 5 (5x200) amp, but it's an unfair comparison as 2805 MSRP is 900 & Cary combo is 6500. The Cary components have the best sound I have heard with my system to date, but I want a lower noise floor, would prefer balanced connections, and want a multichannel stereo mode w/o having to use Dolby PL or DTS Neo. Also had a ground loop that I could not get rid of, even after completely unhooking all cable components. The rotel amp did not have a ground loop problem. Next demos will be Parasound Halo (C2 & A51), B&K, Krell and possibly Classe. Will be happy to comment once I have demoed any of the above.
From my personal listening experience, the RF-7 & RF-5 significantly benefit from a pre-amp/amp combo, both from a clarity/detail standpoint, as well as providing better seperation between low/mid/high and also a dramatic increase in the soundstage. With the Cary amp, bass response was such that a subwoofer is at the bottom of the to buy list.
As for budget concerns, I can certainly understand, but would still recommend without reservation the RF-7 as fronts & RF-5 as rears, or on more of a buget perhaps 4 RF-5 + a center channel. I got a fantastic deal on my RF-5 speakers, which were purchased new. I have heard that Klipsch is going to revamp part or all of the reference series line, so shop around for deals. I demoed the RF-35, and the RF-5 is a much better speaker for not much of a price increase. Also, my RF-7 & RF-5 speakers are very dependent on the quality of components they are mated with. The 2805 is a great receiver, with a multitude of features and quite easy to use once your used to it, and it works very well with the 2910 universal player. I primarily listen to 5 channel stereo, or pure direct/extension in with the 2910 set to direct/all off as well. This setup provides a very clear, clean, transparent sound quality, as it should. However, it lacks the soundstage, body and bass response of the Cary Audio in analog bypass when combined with the Cinema 5 amp.
If anyone has Klipsch RF-7 &/or RF-5 and is using seperates, would be very interested in hearing about what you have liked & what you have not. I'm also interested in Anthem Statement, but nearest dealer is Cincy which probably excludes a home demo.
I have zero regrets in my choice of speakers, and would highly recommend either the RF-7 or RF-5 as great speakers at their particular price points. B&W makes very nice speakers, but I would have to spend a great deal more money on B&W speakers to get the same sound quality I have currently with my Klipsch reference speakers.
