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.

@olesno I will have to make sure to give serious consideration to Tekton if I decide to upgrade my speakers.  Not sure they would pass the WAF though 😀

@minatophase3 They are big and heavy and visually imposing.  I got used to them and my better half likes to listen to music with me so it wasn't a WAF issue at all.  Mine are piano black so they look cool too.  


Yeah. I currently have the No.8 which is also 10k balanced.  I was just using the 20x  for impedance matching and it seemed legit to me. $200 for extra room is a good deal though. I'll reach out to them. Thank you.  

Hello there - this thread is a textbook example of how a discussion should be conducted - to learn and provide tangible experiences that may help fellow users. Bravo. I'm following this discusssion very closely as I'm interest in the S5.5 as well and would like to build my current system around it. I now use a CODA CSiB integrated which has been my first foray to the brand. I must say, I love their sound, build quality, and even the looks. Like one poster early on said, maybe @yyzsantabarbara, "the CSiB is what got him into separates..." I feel the same way and want to head down that path too. Right now I have the CSiB feeding Klipsch Cornwall IV's, Holo Audio Spring 3 KTE DAC, and my weak link, Bluesound NODE 130 streamer with upgraded LPS. I'll be upgrading to an Innuos Pulse very soon, but wondering like others which pre-amp to go with; especially considering the Cornwall's are here to stay. Although I'll likely consider some Volti's down the road. Like its been said, I could certainly use the CSiB as the pre-amp and I'd been fine with that, but also open to other options. Short list looks like Holo Audion Serene, Backert Labs Rhumba Extreme, and possible LTS MicroZOTL tube pre-amp. Any thoughts or suggestions are very welcome. Thanks to @johnah5 for starting this discussion and folks like @vthokies83, @yyzsantabarbara, and many others for providing such great hands-on experience with the CODA products. Thanks and looking very FW to that S5.5 review!

Soundstage-wise, are all images at the speaker level and behind …or do images also project forward of the speakers. I’m principally thinking of solo vocals or instruments in this regard. Thx:)
