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.

           Thank you Aric for your fast reply and the information. I can picture them better now on their stands; the Spectre 12  w/stands being about the same height as a Magnepan LRS+ . I think that's a great height for the ribbon tweeter too! Excellent!

            I have been  looking at the products you offer and various reviews along with comments on this thread and am very impressed with the products you have to offer, your high quality ethic, and the fact that you have a strong customer focus based on your guidance to customers for their specific applications. Thanks again, and when I am ready to move on changing some of my components, you are right at the top of my list! Thanks again. Best, joe

Some additional observations on the Serene preamp. I disconnected the Serene from my office system (Magenpan LRS+ and CODA #16) and drove it down to my friends place in Ventura, CA.

I wanted to hear the new RAAL 1995 Magna and Immanis headphones. I am a 2-channel guy but the older CA-1a and SR1a are spectacular, and I wanted to hear the new ones that are supposedly way better.

I took the Serene because it has a headphone only XLR output on the back. Last week, I spent $200 and bought the required cable from Kitsune.

My friend was building a crossover less speaker. It was a prototype and we listened to it with a passive preamp (volume control) that he had also built and my Serene. After just a few minutes I could tell that the Serene was outclassed by the passive. Everything was better across the board. I would expect the same result if I used that same passive preamp with the CODA #16.

My friend is thinking of building a balanced 4-input passive with dual XLR outputs. I told him to keep it cheap and let me know. I am keeping the Serene but no longer with the CODA #16. I will move the Serene downstairs to function as a headphone amp and 2-channel preamp.

The 2 new phones I heard were amazing. So good that I want to get the one I preferred for rock music, the Immanis. I am not sure how I can pull that off without selling the CODA #16. If it has to go it will, to get the Immanis.







Your #16 might be a hard sale now with the S5.5 raves making the rounds…with the cost difference in favor of the latter.


            What was your music source gear feeding the serene and the passive?

             Great find on a simpler, cost effective,  yet capable, passive path! Kudos to you and your friend!

@aolmrd1241 The S5.5 is not really comparable to the #16.  Definitely with the speakers I listen to. I have 2 other amps that I think I can sell I and I am exploring that first. Though that would mean 1 system will be unplayable.

@firefly627s I took down my great streamer and DAC and cables. However, his router was in a spot behind 200lbs of marble. We said the heck with that has just used a low-end CD player into the Serene connected by RCA. This was only for the crossover less speaker. We used a computer and RME DAC for the more elaborate phones tests with my incredible RAAL VM-1a amp.

Next week the phones I heard are heading off to The Absolute Sound and then Stereophile. I do not think they has as good gear as I have for these phones.

One reason I want to get whatever he builds is because I think he is a bit of an audio genius. Stevie Wonder uses his mic's, Keith Richards uses his guitar strings, etc ...
