I took delivery of the Krell S550i 5 days ago along with Argentum Myth Analog I/C's and the AURE 8ft bi-wire speaker cables,(Studio 100v5 looking to upgrade to B&W 703D) Gutwire basic Clef power cord upgraded fr 15 to 20 amp plug(for s550i) and 2 Gutwire B/12 15 amp power cords(for FMJ BDP-300 BR player and AVR400)
As stated in a comment, I had the blue light flicker, however, it self corrected after 3-4 days burn-in.
Every time I power up the Krell I shudder, as there is a electrical pulse resulting in a thud to Base.
I am nor t getting that low base slam that Krell is famous for and am very disappointed in the Argentum cables.The dealer told me that they are superior to the Audioquest Columbia (replaced by ELEMENT-Water) I asked for a set to demo and was advised there was none available (first clue.
The midrange jumps out with detail and the tweeter sounds veiled, hopefully not due to the Krell as I invested $4,900.00 CDN.(slight scratch on LCD and face plate is not flush, 1/16" or so, with enclosure side. Dealer glossed over this point and was not willing to do anything?
At least dealer is playing fair and replacing the Argentum with the AudioQuest. 2 Water Analog I/C's and an 8ft. bi-wired Rocket 88. The Castle Rock a little out of my league right now.
When I get the new cabling, I hope to have a better idea of the sonic performance that the Krell has to offer, ideally after 100 hrs. burn in
