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.

Am I correct that there is no way of purchasing a 5.5 with a trial period or any money back return period,  in case the buyer concludes it’s not the best match for his or her system?


A good question I think others are curious about.  Another poster asked this early on, I easily may have missed it, but I don’t remember it being addressed.  Maybe it will be included in the online review.

Hey Guys,

I did address what is the difference between the Pass Labs XA-25 vs. the Coda S5.5 earlier in this thread. I have owned the XA-25, its a great amplifier, my favorite of the present XA generation of Pass Labs amps, The S5.5 is quieter, more detailed, faster/dynamic, with tighter bass, and a much more airy extended top end. Both are great amplifiers, its a matter of personal taste and synergy with your system.
