Summary: Reading Lawrence's review below, he seems to have been very unlucky. Mind you, I have contacted Krell a couple of times and also received no reply, so I'd agree with that bit. Downsides of the Krell s-300i - getting it home (heavy!), the remote eats batteries quite fast and your choice of inputs and outputs is a little limited. It also runs warm, so heed the instructions about leaving space all round the amp.
Summary: Great Amp when it works, but a real pain in the butt when it doesn't, when I got this amp several problems happen at the same time, Display was having blocks and unreadable, preamp left channel kaput, then entire preamp section went dead, IEC connector for Live wire came loose, the entire IEC was arching when I turn it on, believe me that is one hell of an experience. All resolved by my local dealer, promptly except for my Display.
Summary: I bought in hongkong for 1900 dollars plus free shipping in ebay thats why I rate it 4 stars in value, I really havent heard other hi end manufacturers except krell, this is an upgrade to my ADCOM 555 mk2, i say its one hell of an awesome amp, it grips my Magnepan MG 1.7 hardcore, soundstage is deep, something 3 feet from the speakers and extends upward it is maybe because of the planar characteristic of the 1.7 (awesome soundstage), both are match made in heaven.
Summary: Just bought this 2nd hand. Its worth every cent. Unbelievable control and grip over my sonus faber grand piano domus speakers. I used to have a KAV-300i and this was an upgrade and a worthwile one. The difference between the 2 is that the S-300i has got better sound stage and presents more depth of detail. It presents all the individual components without losing the plot.
Summary: Gamla bettan. Skulle bara sakna henne om hon försvann ur mitt liv. När man väl har köpt denna stärkare kan man inte sluta lyssna så länge man har ett par Audio Physic att koppla in. Passar som handsken. Låter magiskt tillsammans. Ett måste att testa.
