gparker777 Posted November 8, 2020 Posted November 8, 2020 (edited) Further information: My beloved and highly regarded Krell KMA 160 Class A mono block amps. I am the second owner acquiring them in 2013 from the USA. As they have dual primaries, the switch to full 240 V configuration was done easily by Eddie Lee in Ryde who used to service Audio Research amps for the distributor. At the time he said these are the best Krells he had ever heard. In mid 2017 the amps went in for a full restoration with Trevor at Rage Audio; taking over 18 months meticulously tracking down original components and replacing all output devices, emitter resistors, driver transistors and capacitors - a true labour of love. These tireless heavyweight amps look and sound fantastic and were the centre piece of my system driving B&W diamonds with consummate ease, up until an upgrade in late 2019. Typical of Krell's high current amps able to drive almost any speaker and yes, they draw a lot of juice. Cosmetically they present as very good, with some minor scratches on the top place as seen in the images. Do not have original packaging or manual and no power cords supplied. Local pickup preferred, however happy to investigate a pack and send create option at buyers expense including insurance. Specifications Power output: 160 watts into 8Ω (mono) Frequency response: 20Hz to 20kHz Total harmonic distortion: 0.1% Damping factor: 800 Input sensitivity: 1V Signal to noise ratio: 120dB Speaker load impedance: 1Ω (minimum) The amps have 4 pairs of binding posts that are in parallel configuration so you can bi, tri or even quad wire speakers. Their output is 320W into 4 Ohm, 640W into 2 Ohm and a whopping 1280 into 1 Ohm. Dimensions: 591 x 229 x 537 mm Weight: 35kg per amp Photos: Edited November 8, 2020 by gparker777 9 1
kelossus Posted November 8, 2020 Posted November 8, 2020 (edited) For a fully rebuilt pair by a reputable tech like Trevor this is an absolute steal. How many manufacturers actually specify 1 ohm output. You can trust these old D'Agostino designs could deliver every bit of power specified. Real sledgehammers. Edited November 8, 2020 by kelossus 3
