I just recently purchased this unit and ma awaiting its arrival. I bought it through ebay from what seems to be a reputable seller. I was in the market and this was available at a decent price compared to others I was looking at(marantz mm9000, adcom gfa-7000, acurus 5125, sunfire cinema grand, etc...). What I would like to know is if I should have this amplifier sent out to a repair shop and have them inspect it and/or install any sort of upgrade before using it to drive my speakers or if I can just hook them up as is and home they last another 10 years. They will be used to drive Polk RTi10s, Polk CSi40, Polk monitor 60. I am going to use my Yamaha rx-v863 as a Pre/Pro for the the time being till I can free up some funds for a decent Pre/Pro.
Any help would be much appreciate. Especially if anyone knows of any hifi stereo repair shops in Washington DC area.
