Hey All,
I am selling my Denon PMA-2000AE Integrated Amplifier.
It is a huge beast of an amp! Looks amazing, sounds amazing and have a great MM/MC phono stage.
It’s in fantastic condition. There’s a small mark on the side panel and a little wear to the remote. Other than that it is perfect.
Asking £400.
Collection only due to size/weight.
Here is the blurb from Denon, pics below.
■ UHC-MOS Single Push-Pull Circuit, for balancing details and power
The PMA-2000AE features UHC (Ultra High Current) MOS circuitry that has been developed to balance advanced speaker drive capabilities and improved sound quality. UHC-MOS technology uses a minimum number of amplifier elements while achieving approximately 10 times the normal supply of current, balancing artistic expression with high output power. The PMA-2000AE thus masterfully reproduces the full sonic range from soft delicate details to powerful transparent climaxes of a musical performance.
■ Independent preamp and output stage power supplies, plus powerful High Current Dynamic power circuit
The preamp power circuit that requires stable voltage and the output stage power circuit that requires a large current supply have been placed independently from the stage of the power transformer coils. This configuration of the power circuitry that eliminates adverse influences caused by the operating current of the output stage significantly enhances the resolution of the preamp stage handling low-level signals. On the other hand, large-current Schottky barrier diodes have been used for the rectifier elements to support the expressiveness of the UHC-MOS with their low-noise characteristics and high-speed operation. And a large-capacity, block-type electrode capacitor for audio applications has been used for the power capacitor. This power circuitry supplies clean, stable power to realize a sound space that eminently balances delicate musical nuances and high power.
■ Power Amp Direct and PRE OUT terminals
The PMA-2000AE is equipped with a Power Amp Direct terminal that enables direct input to the unit's power amp from another preamp, and a convenient PRE OUT terminal to which another device such as a power amp or subwoofer can be connected. The Power Amp Direct function can be turned on or off via a switch on the front panel. This function can be used in a variety of applications in an A/V surround system without requiring complicated set-up procedures. Plenty of consideration for sound quality has been given, such as PRE OUT terminal using output from the discretely-configured flat amp of the MOS-FET output.
■ Wide Range Playback, supporting next-generation audio
The volume, tone, and power amp circuits have each been reviewed, resulting in a playback frequency with an upper limit of 100 kHz during actual use. This wide-range playback feature supports advanced audio formats such as Super Audio CD and DVD-Audio.
■ Precision Signal Ground Circuit, to protect signal purity
The Precision Signal Ground circuit, a standard for signal amplification, minimizes the effects of noise in the ground circuit to ensure a stable ground phase. A clean, transparent sound is produced, since the signal is amplified under ideal conditions.
■ Precision Mechanical Ground construction, to thoroughly suppress vibration
The vibration-resistant construction was reviewed to ensure that the adverse influences of vibration on sound quality are thoroughly suppressed. The power transformer, a major source of vibration, has been "float" mounted using a variety of vibration-resistant materials. The radiator has been dampened with a vibration- resistant material and a radiator stabilizer, and by mounting the radiator near the foot, interference with the power transformer and other sources of vibration is minimized. These and other measures to minimize the effects of both internal and external vibration, such as in the mounting and placement of the various parts, contribute to impeccable sound transparency and improved sound localization.
■ Chassis construction with 6 independent blocks
The PMA-2000AE features a twin monaural axisymmetric construction with separate power amp blocks for the left and right channels to prevent mutual interference between the circuits, shut out noise, and obtain a clear stereo image. Circuits with different signal levels have been isolated into six separate blocks. And 1.6mm thick black-coated steel plates have been used for chassis to eliminate sound coloration caused by mutual interference between the blocks and ensure the playback of sound with a clear sense of space.
■ Twin transformers with Leakage Cancelling mount
Two transformers have been connected in parallel to dramatically improve electrical and magnetic characteristics. The Leakage Cancelling (LC) mounting system, a method of cancelling mutual magnetic influences, has been used to minimize the leaking of magnetic flux, a source of noise inside the amp. The method in which the transformers were mounted also used a combination of special resins and vibration-resistant materials that produce a floating effect to prevent adverse influences from affecting sound quality.
■ High-performance phono equaliser
The PMA-2000AE includes a high-performance phono equaliser in a discrete configuration that uses low-noise FETs at the first stage. The use of a dedicated power supply gives the phono equaliser stability and results in high-quality-sound playback of analog records. The rear panel has a MM/MC switch to support to use of a MM or MC cartridge.
■ Parts strictly selected for high sound quality
OFC wire has been used for internal wiring to preserve the naturalness of sound with minimal distortion. The PMA-2000AE also uses many other parts, such as film capacitors, electrolytic capacitors, resistors, and inductors, that have undergone stringent listening tests for their suitability for high sound quality while DENON was developing the high-end PMA-SA1 and PMA-SA11. All have been carefully selected and tuned to ensure they do not add any particularities of their own to the quality of the original sound.
■ Machined gold-plated pin jacks
Machined gold-plated pin jacks for PHONO and CD input have been installed with sufficient space between them to accommodate large, high-grade pin cables. Audiophiles are thus able to choose their favourite audio cable to suit the sound they are looking for and improve the overall sound quality of their system.
■ Microprocessor Stop Mode
The Microprocessor Stop Mode automatically stops all operations of the micro- processor during playback when the microprocessor is not needed. By stopping the microprocessor’s clock oscillation, these adverse affects on the sound signal are removed and the quality of sound is improved.
