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 Dale said the S5.5 does about 40 watts into 4 ohms…No doubling anywhere!

I am going to pick up a used CODA S5.5's when people decide they want more power. I think it will be great with the soon to purchase RAAL 1995 Immanis headphone. I have something like 5 ways to play those phones, one of them being the $800 Schitt Aegir amp (pretty good). The S5.5 should be better than the Aegir. The other amp I considered was the First Watt, but I think CODA amps are more to my liking.

This has been (kinda) covered before, but I can't get over that the R&L inputs and speaker outputs are reversed as per the owner's manual. Any amp I have owned has the R&L connections "correct when facing the amp. So, does one just ignore that and hook up cabling as though they were not reversed or do you follow the manual instructions? If the instructions from the manual are followed you will have to cross the cabling. Are people doing that?

From the manual:

I. Connections
The connectors and controls are clearly marked on the back panel of the AMPLIFIER. Note the correct left or right channel orientation. The function and channel markings on the rear panel correspond to the front panel controls and their signal paths.
1.The UNBALANCED and BALANCED inputs should be attached to the appropriate unbalanced and balanced outputs of a preamplifier either directly or through a crossover or processor, as appropriate to the application.
2.The LEFT OUTPUT and RIGHT OUTPUT should be attached to the left and right speakers"

@aolmrd1241 Seriously? 40 watts into 4? Here is the claim on the Destination Hi-Fi website: "Rated Power: 50 Watts Class A into 8 Ohms, 100 Watts per channel into 4 Ohms, 200 Watts per channel into 2 Ohms." 
Both can't be true. Must get to the bottom of this before proceeding further!

@grk it's very confusing. Just put the speaker cables like you would normally put...

Also the interconnects..I did what the manual said..soon I realized listening to tracks I know the channels were reversed. I swapped them like I did for the speaker cables and was back..

Not sure why Coda has it like that in the manual..very confusing
