AudioPrism and Red Rose Music


AudioPrism was a specialty audio company based east of Seattle in Redmond, Washington. Owned and operated by Byron Collett (Sales and Marketing) and Victor Tiscareno (Engineering). AudioPrism produced  tube based preamplifiers, amplifiers and audio accessories.

 The Mantissa preamplifier, Debut stereo amplifier, and Mana mono amplifier were well reviewed products sold thru dealers in the U.S. and Internationally. The Mantissa and Debut were available in a standard and Silver Signature version with upgraded parts and wiring. The Mana did not have a Silver Signature version. The standard color for the units was champagne with the option of ordering them in silver and black anodized. The external power supply for the Manitissa was painted black.

 Accessory products included the Isobearing, CD Stoplight, CD Blacklight, Quietline, ACFX, Power Foundation, Waveguide, Noise Sniffer and FM Antenna. These also were well reviewed products and remained under the AudioPrism label after the sale to Red Rose Music.


AudioPrism accessory products are again available  thru dealers and may be found at:




Red Rose Music


 Mark Levinson (the man, not the company) listened to the Mantissa and Debut and, as the saying goes, liked them so much he bought the company. AudioPrism tube electronics were updated and then sold under the Red Rose Music name.

 The standard color became silver, parts were upgraded and some circuit changes were made. The model became Model 1 (Mana), Model 2 (Debut) and Model 3 (Mantissa). Silver Signature versions were also available for the Model 2 and Model 3. The Model 3 Silver Signature replaced the Mantissa Silver Signature Reference and was only available with the larger supply providing additional voltages. Improvements were later incorporated and the Model 2 and Model 3 became the 2a and 3a respectively.

 Solid State electronics were introduced with Rosette 1, Rosette 2, Passion and Affirmation. These were private label products that were extensively modified prior to production. Later, the Model 150 was developed and built in-house  at Redmond

 Red Rose Music had the Model R3 and Revelation speakers at the time of AudioPrism acquisition. Later was produced a line of speakers that had been heavily modified in Redmond prior to production and introduction. A center channel speaker was designed in Redmond. 


The Redmond facility was closed in December 2003, tube products were discontinued and the employees released. Red Rose Music continued to sell the solid state electronics and speakers.
