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.

I find the comments regarding Class D amps lacking “soul” very interesting when compared to good Class A or AB SS amps and tube amps. I recently purchased some Class D mono blocks to be used in lieu of tubes during the summer and could not describe the difference any better. I think Class D have come a long way in the last few years, but also feel they have a ways to go.

@yyzsantabarbara I am now the proud owner of that Coda 16, and my initial listening impressions are pretty stunned for the positive. I saw you share that and didn’t chime in to jinx anything until I bought it!


Compared to the JC5, everything is better. It was substantial enough where even my wife unsolicited was impressed. I didn't expect such a dramatic change just switching amps. I’ll continue listening and share as I go.

@christianb5s4 The #16 definitely is a great amp. Now that I found some speaker cables that do not mess up the sound, I have no complaints with the #16.

I actually had my #16 up for sale at the same price a month ago but I pulled the ad after the speaker cables were sorted out.

Just looked up your gear. The #16 will play very nicely with that gear. I had a CODA 07x preamp at one time, which is likely similar to your PASS, it was a nice pairing.


@yyzsantabarbara I decided to start with the XP22 because it while maybe not the most excited or colored, it’s still very good as a neutral reference point since I was just starting my journey then.


Now that I’ve got the amplification leveled up, the goal is to try a great tube pre.
