SPL PHONITOR ULTRA MODIFICATIONS
 

Our head Engineer in our New York clean room facility recently finished an ultra modification for the SPL Phonitor. Right out of the box, the Phonitor incorporated in a properly constructed headphone system which addresses the vibration of the current flowing through the circuits of the components and the vibration from the floor of the room using the www.mapleshaderecords.com platform system and with true high-end power and interconnect cables fitted to all the components in the system was and still is among the best of the best. It offers a wonderful tube like quality and goes so deeply into the music conveying the music with emotion and soul equal to or beyond the top headphone amplifiers currently available.

The Phonitor sonic advantage is due to its innovative 120 volts reference technology based on handmade operation amplifiers. 120 volts corresponds to approximately four times the performance of standard analogue audio semiconductor technologies and twice that of the mot powerful designs. Through such 120 volts circuitry and processing the Phonitor's performance levels are far beyond conventional designs in dynamic range and distortion levels, and the main technical specifications in music reproduction exceeds all known analogue or digital standards.

This in addition to the circuitry the Phonitor incorporates to correct the unnatural phenomena which occurs when listening to music with headphones makes listening a truly enjoyable experience as it will enhance all recordings and correct the ones which do not sound good or natural when listening with headphones.

After our modifications the Phonitor brought out even more tube like qualities with depth, soul and emotion that all of us here at Stefan AudioArt have honestly never experienced from another headphone amplifier at any price.

 

ULTRA MODIFICATION PACKAGE A:

  • Burson Audio HD Opamps (matched pair) simply one of the best op amps in the world.- replacement for Phonitors LT071 opamps

  • DEXA Ultra Wide Bandwidth 78XX and 79XX Audio Power Regulator - replacement for Phonitors standard LM7812 and LM7912 fixed voltage regulator. More than 100 times better ripple rejection, 10 times lower noise, and no line and load regulation error.
  • TKD Conductive Plastic Potentiometer - replacement for Phonitors ALPS Blue Velvet 10K Potentiometer. The TKD (Ko-on) potentiometers are highly regarded, probably the best pots in current production. Used by Audio Note, LAMM and Kondo. TKD makes excellent feeling and sounding volume controls. Once you've heard (and felt) the difference between a $17.00 volume control and a $70.00 control you'll understand why people go to such lengths to get cheap controls out of their signal path.
  • Power supply electrolytic capacitors upgrade 2200uF / 100V, KG Series, Gold Tune, (x6) 2200uf / 35v,  Fine Gold Series,  (x4)
  • All of the above upgrades treated with Stefan AudioArt's proprietary conductive surface enhancement procedures to increase the performance of each part.

 THE ULTRA PHONITOR PLATFORM SYSTEM :

         Using selected Mapleshade maple platforms, and brass footers we have designed an extremely effective way to drain the vibration
         from the chassis by removing the top and bottom plates (and legs which attach to the bottom plate) and replacing them with 2"
         thick 15" x 12" Mapleshade maple platform. The frame and circuit board are then screwed into the bottom 2" thick 15" x 12" maple
         platform (with brass screws for the best vibration control) attaching the Phonitor directly to the platform. Underneath the bottom of
         the 2" thick 15" x 12" maple platform 3 Mapleshade brass footers are screwed in to support the Phonitor replacing the stock
         supports which considerable degrade the sound. The other 2" thick 15" x 12" maple platform is simply placed on top of the
         Phonitors frame. This system is then placed on a 4" thick 18" x 15" Mapleshade platform with Isoblocks underneath the 4" thick
         platform.
