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.

@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.

  Terry, Your prior review on the No. 8 amp from Coda was very influential in my long thought out decision to purchase the CSiB. No regrets. It offers in my system everything you stated about the No.8 and what Richard Willie reported in his review in Stereo Times. I was researching amps for a couple years and very pleased with the CSiB decision. I am planning to replace my McIntosh MC2125 amp and looking seriously at the S5.5. I spotted it on the Destination Hi-Fi site a few months ago. Seeing your comments have revved me and I plan to talk with Doug Dale and James at Destination Hi-Fi. Both gentlemen have been extremely helpful to me. The quality and sound from the CSiB has narrowed my  amplification preference to one manufacturer- Coda. Great quality, sound and value. 

Terry, how do you feel about using the CSiB V1 preamp outs to control the S5.5? My other option is an  ARC SP-8 Tube preamp that still performs well? I did some comparisons between the CSiB pre outs and the SP8 pre with a separate power amp (Mac MC2125). The 07x preamp section of the CSiB came very close to sounding like the SP 8 tube preamp in overall flavor; however,  with improved detail/resolution, bass control, smoothness and a much quieter dark  background and cleaner, more evident micro and macro dynamics.  And the SP8 sounds beautiful so the Class A preamp section of the CSiB V1 has certainly surpassed my expectations. Coda=Impressive!!! What do you think though about the synergy of either of these preamps with the S5.5? I plan to touch base with Doug Dale at Coda as well on this.  His knowledge and experience has been invaluable to me on prior calls and he is just great to talk with and learn from. With high respect, I do want to thank you for steering me to Coda with your No. 8 review! If you are excited about the S5.5;  that's really enough for me to place an order. Thanks again!
