AVR 137 5.1 Audio Video Receiver, made by top HiFi brand Harman Kardon. With its 5 x 30 watts per channel (8 ohms) or 2 x 40 watts per channel it has more than enough power to also drive heavier speakers. The volume and sound image can be set separately for each speaker. Loaded with connection possibilities, both analogue and digital. And all that packaged in a beautifully designed device with its large display and big blue illuminated volume knob. Expect the best sound you have ever heard from this heavyweight HK receiver! To make it a beautiful and complete set, I have added the matching DVD 27 CD/DVD player for free. In very good cosmetic condition, as is visible in the pictures. (*)The volume knob on the AVR-137 has a small problem, it goes up a bit easier than down. The volume can be controlled perfectly from the remote control. Other than that, both devices are working perfectly. A great set for the true audiophile in pristine condition. Packed with extreme care + Insured shipping + Low shipping costs + Satisfaction guaranteed
