I have for sale a rare Pioneer series 20, D-23 Electronic crossover.  If you're looking at This ad, you're probably familiar with the unit so I won't go into too much detail as plenty of information is available on the internet regarding this unit.  The unit can be used as a 2, 3, or 4-way crossover and it uses very high-quality parts and construction which gives the unit a very transparent sound.  Check out the reviews for this unit online and at various audio forums and you'll see it's highly regarded for its sound quality and flexibility.  Please note: This is a 120-volt USA unit which is highly was designed for use in the USA. You will sometimes see these crossovers for sale with a 100 volt rating which means it was originally a Japanese unit and designed for overseas use...with the 100 volt units you also need an adapter to correct the voltage to the USA.  My unit however is a 120-volt version designed for use in the USA. The Pioneer literature refers to the unit as a multi-Amp Electronic Crossover Network, which has Versatile Slope Selection and Superior Circuitry/Parts which are based on the true needs of advanced audiophiles.  The D-23 has super low distortion numbers of 0.005%, 20HZ to 20khz at 1V.  The unit has outstanding signal to noise ratio of 100db IHF Short-Circuited A network.  The unit has independent left and right channel gain adjustments, independent 6, 12, and 18db slope adjustments, and crossover frequency settings.  The Pioneer series 20 gear was the best gear Pioneer ever made and it was made to compete with high end audio brands.  The Series 20 line of equipment was only available for a few short years and then the series 20 line is no longer offered.  Cosmetically, the unit is overall very good condition, it does have some light scratches on the top of the outer cover due to age... the faceplate is clean and in very good condition.   All the controls work fine including and every function works perfectly.  The power on light that’s built into its power switch appears to be burned out but replacing it would require an entire new power switch and removal of the face plate, but the power switch works perfectly.   The original owner’s manual is included for the unit as well and this is pretty rare to offers a full description of the advanced features.  I have a custom fit Styrofoam insert for the shipping box that precisely fits the crossover and shipping and insurance will be free in the lower 48.  I will ship via Fed-ex ground.  No international or Canadian sales If you have any questions about this Pioneer D-23 (series 20) crossover please email me at [email protected]  Audiogon does not have a crossover category so that's why it's listed under preamps.  Thanks.
