October 1st is the goal I set to complete the cloud installation of 25 CAP panels. We're halfway there. When complete, the panels will be adjustable on the vertical & horizontal plane. The adjustments will be made via pulley system. Pre-set stops will be implemented to achieve preset angles. The motorized drive system (MAKITA) will respond to AMAZON "Alexa" voice commands.

    Excerpt from Enjoy the Music by Dick Olsher.

    All of this leads me to present the Sound Application CF-X as the perfect solution for the filtration of EM and RF noise (EMI and RFI). This filter uses no transformers or other current limiting devices. It is designed to provide an extremely low impedance capacitive shunt to ground for EM and RF energy over a bandwidth from 10 kHz to 2.5 GHz. That's an upper limit of 2.5 Gigahertz - clear out to the microwave range! I'm not aware of any competing models that can claim a bandwidth beyond the megahertz range. Noise reduction of up to -60 dB is claimed across this bandwidth. Designer Jim Weil, to put it bluntly, is fanatical about construction detail and parts quality. He's the kind of guy that has apparently never read the book "Don't Sweat the Small Stuff," because he constantly worries over small details. The CF-X represents the culmination of 12 years worth of development effort and tweaking. It's interesting to note that Jim uses the video quality of his Sony XBR TV to gauge the effect of various part substitutions. He maintains that visual sensory input in this case is more refined and reliable in making fine judgments. In what follows, I can only give you a glimpse of his attention to detail that is essential in making a parallel filter work effectively over a bandwidth extended beyond 2 GHz.

    All of the circuitry is housed in a machined aluminum case. The internal power distribution is via 4N (99.99% pure) 1/8-inch copper bus bars and 6N (99.9999% pure) copper wire. All internal wiring is point-to-point, and is rated at 100 amps. The unit can safely handle 6 kilowatts of power, well beyond the rating of a standard 15-amp circuit breaker. The filter stages are preceded by spike and surge protection circuitry. A custom high-speed magnetic circuit breaker provides an interrupt time of less than one millisecond for high-current transients - much faster than the thermal breakers commonly used in competing products. A bank of eight varistors follows for voltage spike suppression and protection. A 23-step stage filter bank of high-quality capacitors, mainly film and foil types, is used to provide a near-zero impedance pathway for both transverse and common mode noise. The primary emphasis, however, is on transverse mode EMI and RFI rejection. For effective filtering, it is necessary to cover the desired bandwidth with multiple capacitor sizes, as each capacitor's high-frequency self-resonance limits its upper range of applicability. Did I mention the several pounds of Cascade Audio dampening compound used internally, or that all soldering is performed in an inert argon gas environment to eliminate the formation of surface oxides?

    Make no mistake about it: the Sound Application CF-X is the most effective line filter money can buy. It provides an interface between your audio/video gear and the AC line that protects against spikes and surges and filters RFI and EMI over a bandwidth extended into the gigahertz range. Together with the MAC Delta power cord, this unit is currently my absolute reference. To my mind, the CF-X should be an essential component of every high-end audio system: it simply wipes the X-factor from the AC line and makes the listening experience much more predictable and enjoyable.

HI Dan,
The DP75 is a great sounding RedBook player. There are people dumping these players in favor of streamers. Nothing against streamers, but for those of us that have large CD Collections it would be silly to sell. IMHO, Accuphases strength is in Digital. The drive mechanism and case work are stellar. These days I rarely spin discs. My DENON HEOS streamer (COAX or Optical) feeds the DP75. The processors are smooth as butter. The 85 however, will trounce the 75 in resolve. 


Great system.
How do you like the Accuphase DP75 CD player?


Updated plans for our "RADIO" (Reference Room) using our new C.A.P. (composite acoustic panels). See plans below.


Damn impressive! Congrats!


Thank you Mr. 996cupracer  or is it Mr."GT3 Mezger" Given your username I think we have more in common! -Kayodebun Thank you as well. I will post more images of my audio museum. I'm a bit of a hoarder. Thank You David C. AKA toudou for your support and taking the time to write such a nice comment. Can't believe it, but c o r e is quietly going on its 15th year. Talk2me, I've been an AgoN member since '98. This is the 1st time i've participated in Audiogon's "Virtual Systems." This is the happy side of Audiogon. Keeping it fun is what it's all about and learning from others. Too much bashing on the other side.  I hope to be a good contributor.


Your system makes me giggle with delight! Really cool array of great gear. Being a fellow Wilsonphile, I would love to hear your rig.


Awesome gear and room. Very inviting, like a siren's call to come listen to me.


Beautiful set up! I own a set of Core Audio stands and they are simply gorgeous. Arnold's products are simply work of arts.


Absolutely amazing!
