Item: Denon PMA-880R Class A Integrated Amplifier
Location: Sydney - Epping
Price: $300
Item Condition: Excellent
Reason for selling: Accumulated too much hifi gear and about to move to a new house
Payment Method: Pickup - Cash, COD Only
Extra Info: This Denon PMA-880R Optical Class A Integrated Amplifier complete with RC-156 remote control and Operating Instructions is in mint condition. This amplifier was made in Japan in 1993. Amps made by Denon in this era were considered to be the best amps that Denon ever made. These amps hardly ever come up for sale.
I have owned this amplifier from new and it has been very well looked after. The amplifier and remote control still look brand new and are unmarked. It's whole life has been in a cabinet behind a glass door, which is why it still looks brand new.
This Class A integrated amplifier has a very clean, detailed and powerful output that is impressive for both analogue and digital sources. There are no crackles or hums present and it performs just as well as the day I purchased it.
The PMA-880R has a solid power supply that uses a shielded toroidal transformer, and a pair of large 12,000uF capacitors for voltage smoothing and a very substantial heat sink. It features a source direct switch for tone controls bypass and optical connection between amplifier stages for detailed sound. Speakers can be connected via A, B, A B front switching. The speaker binding posts accommodate bare wires or banana plugs. The power rating is 2 x 75W RMS at 8 ohms or 2 x 120W at 4 ohms. The Denon PMA-880R uses an Optical class A circuit design for optimum sound quality. Source Direct can be used to bypass tone controls. The Denon PMA-880R accommodates both MM moving magnet and MC moving coil Phono options via front switching.
The Denon PMA-880R has the following RCA inputs: Phono, CD, Tuner, Aux, DAT/Tape-1, DAT/Tape-2. The amp also has a Record Out Selector a headphone jack, and a loudness button.
The specifications are as follows:
Power output: 75 watts per channel into 8Ω (stereo)
Frequency response: 20Hz to 20kHz
Total harmonic distortion: 0.02%
Input sensitivity: 0.2mV (MC), 2.5mV (MM), 150mV (line)
Signal to noise ratio: 76dB (MC), 94dB (MM), 110dB (line)
Output: 150mV (line)
Dimensions: 434 x 160 x 353mm

Item: Luxman L-509U Integrated Amplifier
Location: Melbourne
Price: 5800
Item Condition: as new
Reason for selling: need money
Payment Method: Pickup - Cash, Paypal, COD Only
Extra Info:
I am one only owner. Bought new for over $8000 in 2012
The amp has never been repaired, works very well. No issues, can give a week warranty.
The unit has never been loud more then 9am because I live in a flat and I like my neighbors.
Winner of SoundStage's Reviewer's Choice Award (February 2009)
"The L-509u was one dead-quiet integrated amp with an ultra-low noise floor, resulting in the blackest of backgrounds from which the music would emerge in solid, focused, three-dimensional images. Additionally, the L-509u was tonally neutral, and did not favor one end of the frequency spectrum over another; instead its sonic signature was geared toward delivering the least-colored, most musically natural performance, regardless of the type of music." "What impressed me most, however, was the L-509u’s control of the bass." "Subterranean? Without a doubt." Click here to be redirected to the SoundStage review. The L-509u features the new high quality electronic selector switch, which is the heart of the C-1000f pre-amp (one of Luxman’s 80th anniversary commemoration models). The sound quality deterioration using the new electronic input switch is now minimal, while channel separation and crosstalk efficiency were raised substantially in comparison with the previous L-550A / L-590A / L-507 /L-509SE. In addition the illuminated position indicator around the input selector knob, makes it much easier to view the selected position even from afar.
The integrated amplifier also benefits from the ALPS volume control used in the CL-88 vacuum tube preamplifier. A massive solid-brass, four gang potentiometer.
The amplifier section has not been ignored either; noise and distortion has been kept to a minimum with the introduction of ODNF version 2.2. The deep, rich, wonderfully textured tone is available here in Luxman’s most powerful integrated amplifier. No compromises made for sound quality; designed for the musical purist. This is Luxman’s ultimate integrated amplifier. * Equipped with ODNF version 2.2 for minimal noise and distortion.
* Solid brass, four gang attenuator from the CL-88 tube preamp.
* Electronic input selector, trickle down technology from the flagship C-1000f.
* Relay power source with large storage capacity.
* One pair of RCA inputs with Luxman's eddy current defeating technology,
* Peel Coat PCB with gold plated traces.
* Power Output Display Meter in dB
* Switch to split the preamp from the power amp.
* High quality phono stage.
* Two pairs of balanced inputs.
* Custom parts designed by LUXMAN, even the paint used on the resistors to denote the value has been carefully chosen after many hours of comparitive listening.
The volume control on the L-509u is a solid brass, four gang ALPs potentiometer, its too heavy to be motorised, hence the lack of a remote control, it does however provide a linear attentuation & gain throughout the range, holding both channels perfectly in balance even at low amplitude. The tone controls might seem like an anachronism in this day and age of minimalism, but they can be remarkably effective in bring to life a less than perfect music collection. We all have music gems in our collection that are sonicly challenging. A lot of the 1980's CDs are quite harsh sounding and the digital glare can be quite fatiguing. Reduce the treble slightly and while the harsh CD is not going to suddenly sound like a reference recording, at least it will now be perfectly listenable. Sit back relax, enjoy the music & forgot about the HiFi. When you want to bypass the tone controls, just engage the Line Straight switch. Printed Circuit Boards normally have a green coat (dye) that can be printed upon, so the manufacturer knows where to place the copper traces and where to insert the resistors & capacitors. LUXMAN's designers don't like the sound of the green dye, so instead they print onto a plastic peel coat and remove it once the traces and mounting holes are in place. Then the copper traces are gold plated to reduce resistance across the circuit. In the photo below you will notice that Peel Coat circuit boards are an off-white color. It’s this fanatical attention to detail that delivers such superior sound quality. The on board phono stage is not an after thought on any of the Luxman integrated amplifiers, rather a well executed pre-preamplifer. The MC input has 55dB of gain (thats a multiplication of 550x) and is suitable for medium to high output MC cartridges, approx .7mV. While the MM input has 35dB of gain. Extensive listening was applied to the high purity, oxygen free copper (OFC) cables which are used to transmit the signal throughout the amplifier. These cables have a minimal audible signature and minimal electrical effect on the audio waveform. Linear wide bandwidth frequency response is achieved by the low measured values of both inductance and capacitance. The result, the cables do not color the sound, but pass it through, quickly. There is a high quality headphone amplifier, accessible from the front panel. The headphone output is taken from the speaker output,, assuring you of the highest fidelity. LUXMAN did not cut corners in the L-509u; notice lots of custom solid copper parts including screws & fasteners & mounting plates. Not to mention the gold plated peel coat circuit boards. This is one channel complete with heat sink. Here is a clever device found on the back of every Luxman powered product. You press the button and it will check the phase of the electricity it is receiving. If the AC outlet in the wall is incorrectly wired, meaning the live and neutral are swapped, a red LED will turn on to warn you. You only need to press it once, when you are installing a product to check that everything is in order. Its a simple mistake, that occurs often, and one that can seriously undermine your listening enjoyment.

Item: Luxman 505u Integrated Amp
Location: Adelaide, SA
Price: 2500
Item Condition: Excellent, mint condition
Reason for selling: Purchased a Devialet 220
Payment Method: Pickup - Cash, Paypal, COD Only.
Extra Info:
Two things to note:
- The remote is dodgy with its Volume control; over the years I have either changed volume manually or use an external DAC as preamp.
- I imported the 505u direct from Japan so it was assembled for the Japanese market and set to 100volt mains electricity. Therefore it comes with a Kashimura TI-20 step-up transformer (photos attached). There has never been any issue playing it here in Adelaide.
The Luxman has been in daily use since July 2010. It has always worked well and given me great listening pleasure.
A User Manual and the original Brochure are attached.
The 505u has a phono input with both MM & MC selections.
It can be used as a pre-amp only or power amp only.
The 505u weighs 21kg with dimensions: 467(W)x179(H)x437(D) mm.
The transformer weighs 4.5kg and its dimensions are 170x135x100mm.
I will post both items if there is no buyer in Adelaide for pickup - postage costs would have to be checked and agreed to.
I still have the original box available for transportation.
