Beskrivelse av varen
Flott DENON PMA-2000AE til salgs. Denne låter meget bra og forsterkeren er strøken. Stor, tung og meget strømsterk!
Forsterkeren kan drive det meste av høyttalere, men trives nok best med noen som ikke er svært tung drevne. Jeg har brukt den på Bowers & Wilkins CM9 med godt resultat.
Om forsterkeren:
The Denon PMA-2000AE uses dual power transformers to provide extended high current capability with substantial power output. The chassis is divided to enable efficient placement of circuits so that left and right signal paths do not interfere with each other and negatively affect sound quality between the two channels. The Denon PMA-2000AE is an integrated amplifier specially designed to reproduce next-generation DVD-Audio and SACD sources with the wide range and high frequencies that give them their stunningly beautiful sound. Since these sources require a frequency response as high as 100 kHz, the power amp circuitry and the volume and tone controls and have been completely revamped.
A high-current UHC-MOS amplification device has been used to boost the power supplied to the UHC single push-pull circuitry.This is an innovative design by DENON that finally resolves the conflicting problem of how to produce a solid capacity to drive the speakers while preserving the delicate details of the music. The Denon PMA-2000R provides 80 watts per channel into 8 ohms with nearly double that into 4 ohms to drive virtually any speaker system. Superior current linearity ensures a stable supply of current to the speakers, bringing out all of the dynamic range irrespective of impedance or efficiency.
To obtain the ability to bring out all the delicate nuances of sound and the need for dynamic speaker drive, the Denon PMA-2000R has adopted a high-current UHC-MOS amplification device capable of delivering a peak current of 120A to the output stage, as much as 3~10 times greater than that of conventional MOS-FET devices. The current supply capacity of the UHC-MOS has been improved to exceed even that of bipolar transistors while preserving the high-quality sound of MOS-FETs. This ideal amplification device also incorporates single push-pull technology to eliminate variations in amplification operation.
The Denon PMA-2000R features dual parallel-connected twin transformers with vastly improved characteristics in the magnetic and coiled wire circuits as originally developed for the DENON POA-S1 monaural power amp. The transformers have also been "leakage cancelling" (L.C.) mounted in order to eliminate mutual interference caused by magnetic fields and other factors. As a result, leakage flux from the power transformers, a potential source of noise, is suppressed to a minimum, enabling the PMA-2000R's power supply section to supply clean, high-quality DC energy to the output stages.
