  1. RP-280F can be had for $400 each shipped in the USA. One of the current great values from Klipsch. I sometimes regret returning the pair I had for 2 or 3 weeks. You would be very hard pressed to match the sonic quality and presentation for the price. Its later model the 8000F sells for $600 or more.

    I have yet to read a single poor review anywhere online for the 280F from actual purchasers. One day soon the new stock 280F inventory will dry up and go away.

    If it is used by NASA there should be data, like an MSDS report. The government runs on paperwork. Please post the name and a link to this fluid you are using. Thank you.

     

    i searched this morning for NASA Contact Enhancer and came up with nothing, no direct link. This is as close as i could locate: https://www.amazon.com/Stabilant-5ml-Kit-Makes-30ml/dp/B001E50GQS

     

    Must be some German magic fluid :)

    That’s a very profound statement....synergy of equipment, listening preferences, and acoustical space all affect the final resultant sound characteristics. It seems for sure that the Crowns do great with Klipsch. I wanted to test if Crown would be just as good with the B&Ws bass sections.

     

    It seems that the general consensus after years of experimentation any many listening hours that Klipsch and Crown are a match made in heaven. I equate that to the tests that Indian forefathers in North America did with homeopathic and natural medicines...after a few deaths, and illnesses, Eventually tested formulas were proven to work. 

     

    I had a Crown XLS 1002 model and for the price, there is considerable power. But right in their published specs THD+N is rated @ .5% at max output. So they get noisy when you crank up the gain. My unit was quiet at low to medium gain, but turn up the gain to 80-100% and you can def hear a hum/noise at the speakers with the input signal paused.

    So you have to respect them for what they were designed to be.......PA amps.

     

    I'm thinking about purchasing an XLS-2502 to run off my avr's pre outs to my mains, knowing I will only use 30-60% of its total output maybe, and below the audible noise ceiling. Class D efficiency, simple DSP signal processing, 440 watts per channel stereo into an 8 ohm load for $600 delivered. And they generate so little external heat. I never ever heard its little fan running across the room. Used the first one bridged to power a passive sub build. No start up pops or bad habits. Where can you purchase that level of power for so little $?

    We will have a swing in temps also in the next few days....50 tomorrow, then down to 10 Saturday night, 8 Sunday night, starting to hate the cold.

     

    Your swing is much more aggressive. I cannot remember 10F down here in 45 years. 16/17F yes, and that is far from typical. Christmas eve 1989 (I remember well because we lost the entire refinery abruptly in the wee hours and had a few fires in the units, I was working nights and it was just plum crazy). And I'm in Hammond now and was 17F Dec 8, 2017. It snowed :)

    I cannot imagine operating an oil refinery in 10F, but they do it day in and day out. My former employer has a refinery in Detroit MI. MPC....Marathon.

    I want no part of < 15F. Stay warm!

    Hello Randyh 🙂 It is not a deoxite ... I do not know the chemical composition of the fluid, but my wife is a qualified chemist by profession and comes from physical chemistry, so the use of chemical fluids to optimize the flow of electrons in copper structures is not a voodoo for her. These fluids are used in many technical areas today ... Thanks and regards

     

    This cannot be for real. Optimizing the flow of electrons in copper structures (inductors) with NASA Contact Enhancer?

    Huh? Somebody's yanking our chain for fun, right?

  6. Got it, thx. I have been experimenting with REW on my two systems, learning the software and it's potential. There is a bit of a learning curve for sure and I have not tried the Psy smoothing yet. But I shall in time. My base cornwall 3 performance graphs from day one testing below.

  7. Really when you look @ the specs of the Anthem 225 (which I did a couple days ago when i first read this post), they are not really that impressive. First is the amp damping @ 80 (their spec). For such a heavy piece I expected more, like 120 or better. Overall unit weight is not the end all, be all but good power reserves require a large Torroidal transformer (or two, the really good amps), so really good old school class AB amplifiers are usually pretty heavy. Anthem 225 @ 42 lbs, not bad. McIntosh amps are really heavy, ditto Luxman. There are exceptions to this as the newer class D amps do not require a large heavy torroidal trans (power supply) as they are exceptionally power efficient. Example of this is a Crown XLS 2502 commercial amp, 1500 watts bridged 8 ohm load, but only 11 lbs.

     

    And Anthem's meaningful noise measurement (rated @ 100 watts in to an 8 ohm load): 0.01% at 1 kHz, 0.03% at 20 kHz (100 W into 8 1)

     

    225 watt = (per channel, continuous RMS, 20 Hz to 20 kHz, <1.0% THD) right from their spec page.

     

    Distortion is audible around .25%, at elevated listening levels. For some peeps its lower, and for some higher. So the Anthem has a low noise floor, but it does get noisy as it approaches its rated power output. 

     

    Anyway, this the analysis of spec data. Just my opinion, yours may be different. The end eval should be your listening experience.

    Your first choice, not the second.

     

    Chris didn't you employ the Yamaha 2060 as an active XO to manipulate and maximize each transducer? I mean each transducer is not driven full range in the end but per your settings within the 2060? precise HP and LP filters employed, equalized (DSP corrections), and corrected for group delay? 

     

    Also, your all SPL graph above, is this with any smoothing? Specifically the orange trace.

    Really nice work with the 2060, the overall response is quite flat. 

    Interesting the graph is taking a nosedive @ 40hz. Down ~ 9 db @  33 hz.

     

    Audio life within the digital domain.......there is no going back now.

    Factory Direct time!

     

    Our tireless pursuit for cheaper products, while expecting better performance, is backing ourselves into a corner.

     

    The days of going into a store to ask questions, touch and test products is short lived, for the most part. I hope I’m wrong. 

     

    Pretty much. People research, read reviews, and purchase on the internet. Go to walmart, best buy, Target, or Costco if you want to touch it.

    99% humidity and upper 60's.  The humidity has been stuck on 99% since Saturday.  Sunday we washed a carpet and put it out to dry.  We still can't bring it in the house.

     

    Same here, humid is the key word. I would like to mow the back yard weeds, but it may never dry out. Slushy, and more rain coming Fri and Sat.

    Thought it was to be "Small"?

     

    Yes, my bad. I was weary when I posted (early this morning). Glen is right........ NAD M10. Four times the power of his current Denon. And very clean power at that.

     

    Only drawback i see for the M10 is no remote control, all functions must be completed via the unit's touch panel display.

    One owner/reviewer does speak of an iphone app to control the unit tho.
