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.

Doug is a great guy. Really enjoyed all our conversations. 

He made it known to me that he's not to fond of tube gear. I've been having tje same issue looking for a balanced tube preamp..  that 10k impedance is usually low. 

Side note.. every discussion i find on different platforms..where CODA is discussed they are always polite and informative. There are a lot of toxic people I'm this hobby and reading through this discussion is a breath of fresh air. 

iovi66,

Fair point about the input impedance on XLR. I've already had this conversation with Aric Kimball of Aric Audio, who is building a Motherlode XL preamp for me. He is modifying it to work with the low impedance of the CODA S5.5.....I believe he is adding an additional 1.0uf cap to compensate.

iovi66 and tmac1700,

       Your comments are very much appreciated and I second both your comments on Doug Dale and Coda. I had a lengthy phone conversation with Doug Dale a couple of days ago. I cannot praise Doug and Coda enough. Doug is a pleasure to talk with, so knowledgeable , possessing exemplary ethics and integrity! I am so thankful I tuned into this company and certainly Terry London and James of Destination HiFi were very influential in my decision.

       I am now trying to decide on adding a Coda No.8 or S5.5 to my current CSiB and control either with the internal ss preamp (07x topology based) in the CSiB. I was initially leaning to the S5.5 and I believe it should perform very well only in talking with Doug,  the topic of current came up for my maggies and possibly a set of Totem Acoustic speakers I am considering. Doug's views are  steering me more in the direction of the No. 8 and he is right on the advantages of  the CSiB essentially controlling twin No. 8s over an S5.5 and a No.8.  You can't go wrong with either amp though, only I may want to experiment with my ARC SP-8 tube amp and not so sure it's going to have as a good a synergy with the S5.5 as the No.8.

        Final decision on this not made yet and in no hurry.  Any comments on tube preamp synergy with the S5.5 and No.8 are factors in the decision process, along with the need for more current with some of my speakers. I see vthokie83 is proactively having AricAudio modify the Motherlode XL tube preamp, so his feedback on that will be interesting. For every problem there is a solution; it's finding it that's the challenge.  Thanks again all, joe 

Vthokie83,

        I am very interested in your feedback on the S5.5's with the Caladan's. It should be Stellar! What is the preamp section? Thanks, joe

firefly627s,

The CODA S5.5 just arrived and installed today, I just turned it on all day and left it to settle in with no listening.....I'll do a little of that tomorrow. The Caladan's are only a little over a week old, but sounding great. I did leave a rather detailed post on my initial listening thoughts if you want to look that over; though those thoughts were with the existing Denafrips Thallo amp.

Until I receive the Aric Audio Motherlode XL, I'm using my current Denafrips Hades SS preamp
