For sale:

Audiophile quality Onkyo Integra M-504 power amplifier.

Low Impedance Drive with Discrete Outputs:
165 watts/channel RMS (8 ohms)
530 watts/channel dynamic power (2 ohms)
Real Phase & Delta power supplys
4 x 2 multi capacitor block
Dual Mono Design
Linear Switching
4 way speaker selector
High Speed Peak Power Meters

Warm, powerful, and uncompromising sound... A very solid performer.
Even the hardcore audiophiles will love the sound quality.

The M504 has great detail, very good dynamics, tight fast accurate bass, exceptional channel separation, it sounds timbrally accurate, has an open and airy quality with both my digital and analog sources, and it is not bright at all. Probably the most aesthetically beautiful power meters in the buisness, kind of like a McIntosh amp, but with a green backlit ambiance.

Also up for sale is a mint condition (10 out of 10) NAD 2400 PE stereo amplifier.

With continuous test tones its output is conservatively rated at 100 watts per channel, while its Power Envelope circuitry produces up to 440 watts per channel of tone-burst power for music. The high-current output stage of the 2400 delivers peak currents up to 40 amperes for precise control of voice-coil motion with speaker impedances as low as 2 ohms. In bridged mono operation the 2400 produces over 200 watts of steady-state power and over 800 watts of dynamic tone-burst power. To enable the user to make the fullest use of the available power, a warning light illuminates if the amplifier is over-driven into distortion or exhibits any deviation from linearity. A high-precision circuit continually compares the input and output signals and flashes the LED if a potentially audible difference is detected. Each stage of the amplifier (input, driver, and output) is individually decoupled from the power supply to prevent the dynamic supply-modulation distortion that causes some amplifiers to sound “veiled” and muddy.

This is a very clean and powerful sounding amplifier.

The sound is very clean, honest, accurate, involving, detailed, enjoyable, etc. Words really do no justice. The NAD 2400PE will play anything anytime time and will involve the listener, demanding their attention. This amplifier has tremendous output and bass yet all the detail is there, and all done with complete and utter ease. Transparency, soundstage, tonality, and yes even sweetness are there. This never sounds dull, distorted, or tired, just the opposite.

High power is not just about loudness, it does so much more...

To buy a new stereo amp of this sound quality you'll need to spend $2000+

I am surprised there are no audio lovers out there.



This is some really nice stuff... :)
