The new Coda S5.5 amplifier: It's a "Petite Beast"!

I have in-house the New Coda Technologies S5.5 amplifier for review for Stereo Times website. It will be awhile before I write the review. However, I'm so impressed by the performance of this petite amplifier, it only weights 45 pounds, that I wanted to give a heads up to you GON members if you are in the market for a balanced pure class A amplifier, delivers 50 watts @ 8 Ohms, and can drop 100 Amperes of current on a peak!

The world class build quality of Coda amplifiers is on display with the S5.5, along with the most beautiful purity of tonality, precise sound-staging, complete liquidity offered by pure class A design, and what might be the best top end regarding details, decays, and a natural shimmering without brightness or any edge at all.

The S5.5 uses extremely wide bandwidth output transistors instead of the usual TO3 devices used in most transistor designs. I own the Coda #16, which is great, but the midrange/high end is taken to another level of musical enjoyment with the S5.5. The S5.5 has a sense of speed/aliveness that is exciting to listen to that you experience in live music. The amp is dynamic as hell, has driven with ease any speaker I have tried it with, hence my nickname of the "Petite Beast". Remember, 50 watts pure class A, can drop 100 amperes of current and only weights 45 pounds.

Please audition Bryston in your stereo before you consider buying. Often in reviews, Coda is compared with Pass as both designers worked together years ago at Threshold. In most cases, the equivalent spec but much more expensive Pass (someone has to pay for all those full page color ads and other marketing) is close but not preferred over the Coda.

Hey jfrmusic,

My dear friend Mike Kay (Audio Archon) is a Harbeth dealer and finds the S5.5 drives them wonderfully. You are forgetting that it's no only the watts but the current loading that makes a great difference in driving speakers effortlessly.

The Pass Labs and Bryston amps pale in comparison to any of the Coda amps, including the S5.5, which can drop a 100 amps. This is almost double the current loading of either the Pass Labs or Bryston.

As a former long time owner of Harbeth C-7s who tried a number of different tube and solid state amps I can assure you that they do like power. However, focusing solely on WPC misses the mark and a high quality amp like the Coda will deliver plenty of juice—I suspect the 5.5 will work very well with the C-7s.

I should be receiving my Coda S5.5 tomorrow. I’ll keep you all posted as to my impressions after a few days as it continues to break in. It will be driving a pair of Magico S5 speakers which need a lot of current. I’ll be comparing it to my Luxman M900U amplifier which is 150 watts at 8 ohms and 300 watts at 4 ohms with the first 12 watts in class A but, must less current.
