Product Description
Custom Design Quadraphonic iRAP Isolation Platform fit under any hi-fi component to absorb resonance and prevent the surface absorbing any sound.
With over 30 years experience designing and manufacturing high quality hi-fi components and accessories, Custom Design's isolation platforms provide audio enthusiasts with a reliable and discrete solution to unwanted resonances.
The Quadraphonic iRAP (Isolation-Resonance-Absorbing-Platform are made from Custom Design's highly acclaimed Acoustic Steel and Acoustic Aluminium. These materials are designed to absorb and dampen resonance vibrations and efficiently isolate your equipment.
It's patent polymer system converts the unwanted resonances to negligible heat, which provides significant improvements in clarity, detail and separation. The result is improved dynamics, especially the bass performance which enjoys better accuracy, precision and depth.

So impressed with the Quadraphonic iRAP that I moved my source out to the side on a new rack and used it with my Naim streamer and PSU.
With the streamer the Quadraphonics made a huge improvement - really cleaned the sound, increased details, moved the soundstage more centre and deeper, filled and lowered the bass, and added a lot more punch. With the PSU, the improvement was also dramatic. The sound is far more involving, clean, crisp, detailed, very lifelike, soundstage moved forward and deeper like a 3D cube, more speed and highly effortless control of the fine details, relentless but controlled sound, and a thunderous controlled slam attack. Clearly notice how lifelike the sound is with home cinema use.
Using Quadraphonics finally on a Naim source (and now in a full system) is a massive night and day improvement just like getting a new speaker.
For the third time - I highly recommend the Quadraphonic iRAP. -

Got another two Quadraphonic iRaps for my monoblocks. These were previously on Isoacoustic Oreos due to space limitations. For the iRaps, I changed the spike and shoe feet to an upside M8 bolt with a small washer, and a bolt plastic cap as the shoe, to act as the feet. This made it all only about 3cm high like the added height with the Oreos. Quadraphonic iRaps are more expensive than the Oreos, but the sound quality is clearly better - a far cleaner crisp sound, deeper soundstage, more fluid dynamics and low details, are the most obvious benefits over Isoacoustic Oreos.
Highly recommend the Quadraphonic iRap. -

Use two Quadraphonic iRaps on a Naim preamp and PSU. For the preamp it really cleaned the sound and brought out new low details. For the PSU it increased the power, dynamics, control and bass detail. Upgrades with the Quadraphonic iRaps (steel and aluminium) are far better than the Isoacoustics platforms (wood) - plus they can come in all black if asked and it takes virtually any unit weight unlike the Isoacoustics variation in wood and colour for bigger weights. Crazy to think a shelf upgrades the sound so much but it's nonetheless true. I will try to fit more where i can.
Highly recommend the Quadraphonic iRap ????
