McIntosh MC206, technisch und optisch gut bis sehr gut in ovp, überholt. Liebe eBayer, ich biete einen McIntosh MC206 zum Verkauf.Das Gerät ist ein 6-Kanal-Verstärker, ich hatte es bis vor zwei Jahren relativ selten in Gebrauch, da ich meistens in Stereo gehört hatte mit meinen (verkauften) MC501, und den MC206 nur für Surround einsetzte.Das Gerät war von 2001-2005 im Vertrieb.Das Gerät hatte ich 2013 in den USA erworben, der Umbau auf 230V erfolgte beim Spezialisten in Mainz.Das Gerät war bei mir selten in Betrieb und funktioniert einwandfrei.Mittlerweile - bei meinem seltenen 5-Kanal-Einsatz noch einwandfrei, habe ich den MC206 vor dem Verkauf bei einem Kollegen, der selbst Verstärker baut und entwickelt, checken lassen; ein Kanal lieferte kein Signal, daraufhin hatte er durchgemessen, defekte Bauteile ersetzt, das Innenleben gereinigt und gründlich geprüft. Auf Wunsch sende ich den video-link nach der Überholung.Wer nähere Infos möchte, wird im Netz fündig, auch gibt es eine kurze Info bei HIFI Wiki.Ich kann wenige Gebrauchspuren am Gerät entdecken, alle mir auffälligen wurden in den Fotos dokumentiert.Das Glas ist einwandfrei und zeigt keine Blasen.Das Gerät macht sich beim Einschalten mit einem dezent hörberen Brummen bemerkbar, das nach einigen Minuten deutlich abnimmt und während des normalen Hörens nicht wahrnehmbar ist. Ursprung scheint der von 110V auf 230V gewandelte Trafo zu sein.Am Liebsten wäre mir die persönliche Abholung mit (Hör-) Test des Gerätes, auch wegen des Gewichtes.Zum Lieferumfang gehört ein Kaltgerätekabel, und die Originalverpackung, sowie eine Anleitung per pdf. Der bis 3000€ versicherte Versand innerhalb Deutschlands kostet auf Grund des extremen Gewichts 50€,ins EU-Ausland auf Anfrage.Der Verkauf erfolgt unter Ausschluss jeglicher Sachmangelhaftung. Auch eine Rücknahme ist grundsätzlich ausgeschlossen, ABER:Sollte das Gerät eine zugesicherte Eigenschaft nicht haben, so nehme ich das Gerät zurück.Ein Tipp - ich habe kürzlich bei eBay ein gebrauchtes Gerät gekauft, für das eine Garantie-Versicherung automatisch bei der Auktion von der Allianz für kleines Geld angeboten wurde. Sehr zu empfehlen.Ich bitte von Fragen wegen vorzeitiger Beendigung der Auktion abzusehen.Viel Spaß beim Bieten!

Mcintosh C200 Reference PreAmplifier. In mint condition. Less than 150 hours of work. I am selling my system and sadly everything has to go. McIntosh released this preamp claiming to be the best preamp in the world. This unit sounds fantastic with much quieter background compare to single chassis Mcintosh preamps that Ive tested and owned. According to the forums some owners have mentioned that they did not notice any difference between the C200 and the later models C500 or C1000. One box is available. The other unit will be packed carefully and to a good standard. Collection is preferred. I have advertised elsewhere as well so have the right to pull out of the this advert on ebay.

(51.8kg) in shipping cartonFor those who are not familiar with this amplifier--McIntosh Labs - the very reputable American company which has produced audio equipment of the highest class for last 80 years - uses black faceplates made of glass with large logo and pointed indicators, highlighted in blue and at this price, you wont find more affordable multi-channel power amplifier than MC205. The amp has beautiful selectors with chrome rims aside the faceplate. MC205 has five balanced and five linear inputs. Acoustic outputs are arranged in two spaced vertical rows and make it easier to connect even the thickest stiff cables in conditions. Dynamic Power Manager ® (DPM): By matching the characteristics of the output stage to 4 or 8 Ohm loudspeakers, DPM insures the most efficient power transfer, reduces distortion, and promotes cool operation; with DPM you get all the power you paid for. The Dynamic Power Manager, which adjusts power voltage of output transistors under the resistance of connected load provides the necessary control over the speaker systems at relatively low for level for a transistor device damping factor (70 referring to 4 Ohm), and extends the range of power, and allows the same amount of watts on 4-Ohm speaker systems as on the 8-Ohm ones. 200W per channel at the distortion of no more than 0.005 % results in 1000 watts totally.Wattmeter: Swift, accurate response reveals program peaks so staying within the power limits of your loudspeakers is easy. Three meters with a logarithmic scale show the power, which is supplied to the front and the central channels. Meters are not relevant for the back channels - the signal level there, as a rule, is several times smaller. Power supply: The system receives all supply power from 12-kg toroidal transformer in special anti-resonant design and from two giant capacitors with volume of 67000 uF. In short the sound of MC205 can be described as breathtakingly neutral. There is no any transistor touch. The device is much better than competitors by the level of micro-dynamic, spatial and harmonic resolution. Detailing at using the balanced inputs is the finest, suddenly such nuances appear which are never heard in other systems. Price when new was $7500. Complete with manual, original all McIntosh shipping box and inner packaging, and power cord. This is your chance to add a powerful five channel amp to your collection which is sure to appreciate over time. Gently used from a smoke-free home—in very good cosmetic and excellent working condition. Best price on eBay. Local pickup preferred, 114 lb to ship. Check my 100% positive feedback and buy with confidence. Manufacturer: McIntosh Laboratory, 2 Chambers Street, Binghamton, NY 13903-2699. Tel: (800) 538-6576, (607) 723-3512

McIntosh MC207 Seven Channel Power Amplifier 200 WPC Very great condition. Wanted to create a theater but never got around to it. Local pick in the Massachusetts Rhode Island area. I will meet it that general area. The amp has no feet. MC207 is a gentle giant of Home Theater amplifiers that is conservatively rated at 200 watts for each of the seven channels. The massively over built amplifier design does not require cooling fans so the most subtle film soundtracks are not masked by common fan noise. Precision McIntosh power meters allow monitoring of the primary front sound stage while clever engineering matches the output of MC207 with all speaker types. MC207 may be used to power a five channel home theater plus two channel remote zone. Power Output Minimum sine wave continuous average power output per channel, all channels operating is 200 watts into a 4 ohm or 8 ohm load. Rated Power Band 20Hz to 20kHz Total Harmonic Distortion Maximum Total Harmonic Distortion at any power level from 250 milliwatts to rated power output is 0.005% for 4 or 8 ohm loads. Overall Dimensions Width is 17-1/2 inches (44.45cm) Height is 9-7/16 inches (23.97) including feet Depth is 21 inches (53.3cm) including the front panel and cables Weight 83 pounds (37.6 kg) net, 116 pounds (52.6 kg) in shipping carton Exclusive McIntosh Power Assurance System A collection of technologies that enhance performance and reliability while protecting the amplifier and loudspeakers. Power Guard® A waveform comparison circuit continuously monitors both input and output signals. Power Guard dynamically adjusts the input level to avoid clipping while preventing harsh sounding distortion. Sentry Monitor Fuse-less short-circuit protection circuit disengages the output stage before current exceeds safe operating level-resets automatically.
