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.

Hmm..I have Pass XA30.8 with Supratek preamp and thinking about this..maybe it would be lateral move? When was the S5.5 released? Is it fairly new?

Hey sim_audio_nerd,

I'm very familiar with your XA30.8 amplifier. Actually your amp and the XA-25 are my favorite amplifiers in the .8 generation of Pass Labs amplifiers. 

I don't believe that the Coda S5.5 would be a lateral move for the following reasons. The S5.5 compared to your XA30.8 will have a more airy/open detailed top end, will present more easily heard micro-details because its noise floor is lower, will be overall more dynamic/faster, and have a more controlled/tighter bottom end. If these differences appeal to your sonic palette you would totally enjoy the S5.5. The XA30.8 is a great amplifier, and so is the S5.5, so which is better is based on your personal taste and how each amplifier matches up with the speakers in your system.


Has anyone tried using two of these amps in bridged mono mode? If so, how does it compare to one in stereo?.  Thanks. 

Hey hanki,

I would love to answer your question, but Coda only sent one S5.5 for review! What are you trying to power that would require a bridged pair of S5.5?
