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.

Here is my impression of the Coda S5.5 amp:

System is:

Quboz->Innuos Pulse streamer->Holo May KTE DAC->Supratek Signature Grange preamp->Coda S5.5->Silversmith Fidelium speaker cable->Coincident Super Victory III speakers (92.5dB/8 ohm load)

To keep things simple, I will leave out all the glory details of my turntable/arm/cart, other cables, tweaks, room treatments, power conditioner etc...

Comparison between Pass XA30.8 & Coda S5.5 - I simply changed the Coda amp for the comparison, keeping everything the same:

1. Speed - Coda is the winner, hands down.

2. Highs - Coda is the winner, by a good margin. More airy and open than Pass.

3. Midrange - Coda edges out Pass.

4. Bass - Coda is equal to Pass (The Coda has been playing around 40 hours or so and prior to getting the Coda, I had to change the rectifier tubes in my preamp. I bought the cheapest rectifier tubes I could find). Maybe with further run-in and changing the rectifier tube of better quality, Coda bass would be better?

5. Micro Detail Retrieval - Coda is winner. I am hearing micro details I haven heard before from my well known tracks. Decay is better with Coda.

6. Other minor details - Coda is half of Pass amp in weight and runs cooler than Pass. I like this :)

7. Build Quality - Pass nudges out Coda, but again it is a matter of personal likes.

Overall, extremely happy with the S5.5. Overall musical fluidity, smoothness, micro detail retrieval, speed, listening enjoyment has increased by a significant margin.

I wanted to thank @johnah5 for starting this thread. Terry, your insights on how the S5.5 would differ from Pass XA30.8 is SPOT ON!!! :)

I look forward to reading your "official" review.

Thanks to everyone else who has helped in this thread to make my decision buying the Coda amp.

P.S= The synergy between the S5.5 and the Supratek Grange preamp is like a match made in heaven!!!

 

 

@sim_audio_nerd as I have a Pass XA30.8 your thoughts and comparisons are really helpful.  Thanks for taking the time to post!

@laginz soundstage is wider and there is increased front to back depth, but depending on the recording of course.

In my case, I was hoping the soundstage would go beyond the left and right speakers. It was always between the speakers. Unfortunately, Coda did not make the SS go beyond the speakers. But I can’t blame the amp. It’s probably my room which is odd shaped...and I would have to figure it out eventually..
