For Sale - Integra Research RDA-7 Amplifier. If you are looking at this ad you need no explanation as to what this amp is! It is in excellent physical condition. One channel needs repair/replacement and it is priced accordingly. The amp has recently been inspected by Adams Electronics (a $180 fee) and all other parts are functional, I have uploaded the repair invoice indicating it needs a new board for one channel. If you are handy you can repair the specific amplifier channel, or bypass the channel and use 6 channels. Or, you can part it out - there is definitely a market for the amplifier channels and the transformers. Again, it is priced accordingly. Buy with confidence - Please check my feedback! Shipping will be by FedEx Ground and only to Continental USA excluding Alaska. Please contact me with any questions, thank you for looking!

.I assume if your looking you know the sound and build quality that this amp represents. Its been the highlight of my main system for the last 20 years and sounds as good today as when new.. Its been in a non-smoking home and was housed a dedicated audio cabinet and was primary used for music. I had bi-amped my main speakers (Mcintosh LS360s) using 4 of the channels and the other three for the center and rear speakers. There is a small area on the top corner of the left front panel that has cosmetic damaged when it was shipped to me as well as one of the channels speaker terminals that was pushed in very slightly. I have included pictures of each area, none of which affected the operations in any way. I had zero plans to ever move it out of my system but came across a BAT VK-6200 at a price I couldnt pass up. It is clear that both amps were designed by the same individual Victor Khomenko.The RDC-7 was $5000 new and was still half price of anything that BAT produced. Its a very large and heavy amplifier. Would prefer local pick up and would be willing to meet someone within a reasonable driving distance https://www.hifidiprinzio.it/files/2014/09/201409262035121.pdf RDA-7 7-Channel Power Amplifier • THX® Ultra Certified • THX Surround EX™ Capable (7 channels) • Low-Negative Feedback Design • Balanced XLR Inputs • Symmetrical Bipolar Topology • High-Current Driver Stage • 3 Gain Stages • Wide Range Design • Massive, High-Quality, Dual 1 kVA Toroidal Transformers • 600 Joules of Energy Storage • Over 1000 Watts of Total Output Power (150W x 7 at 8 ohms, all channels driven) SPECIFICATIONS 150 W+150 W (0.1% THD)(8 ? 20 Hz-20 kHz FTC) 300 W/ch (0.1% THD)THD (at Rated Power) 0.03% (all channels) GENERAL Dimensions (W x H x D) Weight 17-11/16? x 7-11/16? x 23-7/16? 450 x 195 x 596 mm 112.41 lbs. 51.0 kg
