Description from the seller
Harman Kardon HK 505
Technically functional sound on both channels. Tested on all inputs. Switches and buttons are all functional. In original condition. There are optically visible traces of use and some scratches on the front panel. The rotary potentiometer for selecting the input has signs of use, see pictures. Considering its age, it is still in correct technical and optical condition.
The Harman Kardon HK 505 is a highly regarded, vintage 60-watt per channel integrated amplifier introduced in 1978, widely celebrated by audiophiles as a hidden gem for its pristine clarity, exceptional bass response, and massive power headroom. Released as the top-of-the-line integrated unit of its series, it famously incorporates the ultra-wideband, low-feedback design philosophies of legendary audio engineer Dr. Matti Otala.
Technical Specifications OverviewParameterSpecificationPower Output60 Watts per channel RMS into 8 ohms (90 Watts into 4 ohms)Design TypeDC-coupled, open loop, low negative feedbackWeight12 kg (approx. 26.5 lbs)Production Years1978 – 1980
Key ConnectionsPre-out / Power-amp-in jacks, selectable input phono capacitanceKey Review & Performance HighlightsExceptional Sound Signature:Delivers a highly transparent, articulate, and crisp sound.Offers an incredibly powerful, punchy low-end response.Tends to sound much larger than its 60W rating.May feel slightly colder or more clinical compared to older, warmer HK models.Advanced Engineering & Features:Designed with the fingerprints of Dr. Matti Otala to minimize transient intermodulation distortion.Features a customizable phono section with selectable input capacitance for fine-tuning cartridges.Built with pre-out and main-in loops for seamless use as a standalone pre-amplifier or power amp.Build Quality Nuances:Utilizes massive, solid 9mm brushed aluminum side profiles to create a striking vintage aesthetic.Features an underlying plastic front structural plate beneath a thin aluminum faceplate overlay.Manufactured by Shin Shirasuna Corporation in Japan with highly accessible internal layouts for modern servicing.
