  2. thanks for the response... the best multichannel amp that i have ever heard was a gemstone.... the amp is sold factory direct - but you can get a personal demo since you are in the minneapolis area... the designer/owner of the company lives in andover.... http://www.gemstone-audio.com/amplifiers/blue_diamond.php the amp is under $3000 and has a very impressive sound..... i had the opportunity to compare it directly to my carver professional ZR1000 digital amp on the steve's $12,000 dali speaker.... very close in sound (two channel).... give steve a call and set up a time to listen to the amp.... he will even bring one out to your house and set it up on your speakers... good luck!
  3. why are you selling the monster amps? i remember when you first bought them and you were very pleased with the sound....
  4. Bill seems to be the only one in this thread that has hit the nail on the head... the low impedance dips in the lower register are difficult to handle.... most low power solid state amplifiers cannot reproduce low frequencies well on RF-7's (or KLF-30's).... i use a carver pro ZR1000 digital amp that is rated for 225 watts per side at 8 ohms.... it does an amazing job on my KLF-30's.... on the first watt as well as when the musical peaks happen to go over 100 watts....
  5. btw - i stopped the pump at $100 and my tank was still not full (chevy suburban) []
  6. why do you only have 18.5" for your front speakers? if you are putting bookshelf speakers into some sort of "entertainment system" or built into the wall, it will definitely affect the way the speakers sound..... the best sound for almost any speaker is away from the front wall at least 6" to 8" or furthur... as for tipping the RB-75's on the side..... i think that would drastically change the dispersion pattern and limit the horizontal pattern as well as introducing reflection problems from the ceiling and floor...
  7. zip cord is sometimes also called lamp cord.... two wires molded together in a parallel fashion.... speaker wire by definition CANNOT be "balanced".... balanced cable is what pro audio systems use for interconnects - it uses two separate signal lines with a third ground line.... all speaker lines would be considered "unbalanced"..... if your speaker wire came with the term "balanced" on the package - it is simply a marketing term and has no meaning in reality.... 14 gauge or 16 gauge will usually be fine unless you have real long runs (over several hundred feet)... the attached pdf is from the belden website and lists the lengths of different gauges of wire and the percent of signal loss over those distances cheers! 12.32.pdf
  8. i am using a pioneer elite vsx-55txi as a pre-pro with a carver pro ZR1000 digital amp to power my KLF-30's, a carver pm-125 bridged to mono for my KLF-C7, and the internal amps of the elite for the surrounds... the ZR digital amp is GREAT with my KLF-30's.... my eventual plan is to use ZR amps all around....

(KLF-30's and KLF-C7).... there was a very noticible improvement over the internal amps on the pioneer receiver when i switched to my carver pro amps...

  11. i had the priviledge of hearing this amplifier in the designers house here in minnesota... outstanding amp!!! i recommend it very highly.... i compared it on the same speakers (dali MS-5) with my own carver professional ZR1000 digital amp and it sounded very, very close to my amp - maybe even a little better!!! if i had room on my checking account i would have left with one of the blue diamond amps that day...
  12. i will also concur that the carver ZR amplifiers work very well with klipsch speakers... as many of you know - i power my KLF-30's with a stock ZR1000.... simply the best amp i have ever heard on my speakers!!! if i had the cash (or the room on my credit cards) i would buy the ZR1600 in a flash and move my ZR1000 to power my surrounds!!! good luck with your sale!!!

I understand why they would sound better at high voulmes but at low to medium volumes it would make since that they would sound the same wether you were pushing 100 ar 200 watts. ---------------- most high power amps can handle the impedance dip in the lower register than many low powered amps the RF-7's dip down to 2.8 ohms in the bass region..... receivers and low powered amps that cannot handle that impedance will sound noticibly infereior to an amp that is designed to handle very low impedance loads
