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.

tmac1700,

The inputs to the CODA S5.5 is what we are discussing. The RCA unbalanced 50K ohms are no issue, it is the 10K ohms on the XLR inputs. It was not a big deal really, I believe Aric is adding a couple of 1.0 uf caps.....maybe another change? Cost an extra $200 for the mods, and Aric is perfectly comfortable with the pairing with the mods added.

If you have any questions, reach out to Aric....he's quick to reply by email, and a great guy to talk to on the phone

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

tmac1700,

If you have the opportunity, I'd suggest you find a Backert dealer and audition both the Rhumba 1.4 and the Rhumba Extreme 1.4....I think you will find a pretty big difference. The Rhumba Extreme 1.4 is very close to the $13,000 flagship Rhythm in a Rhumba case; Backert confirmed that opinion when I spoke with them.

I found the Rhumba 1.4 was a really nice preamp, but the Rhumba Extreme 1.4 was world class. My opinion is that the Motherlode XL will easily outclass the base Rhumba 1.4, but the Rhumba Extreme 1.4 will give it a run for it's money. I was able to find dealers willing to price the Extreme 1.4 considerably less than the $8,500 list price.

Fred,

Before I bought the Aric Audio Motherlode XL, I auditioned quite a few preamps. The two that stood out the most for me were the BAT VK-80 and the Backert Labs Rhumba Extreme 1.4.

The BAT was out of my price range at $10K (though my friend purchased one which he loves), and in the end I decided I really liked the idea of a 6SN7 preamp. Also I have been blown away by everything I have heard or read about Aric, and my emails and conversations with him have only confirmed that. Really looking forward to that preamp

Let us know your thoughts when you receive it....would love to hear your impressions

piebaldpython,

After hearing my S5.5, and loving it; a friend of mine liked the thought of bridging a couple for his Harbeths. He spoke with Doug at CODA (as did I) who basically told him the same as yyzsantabarbara, bridging the S5.5s is not a good idea.

There is I believe a new System 150/250 coming soon, or is it out already? I'm wondering if it's really the big brother to the S5.5, anyone have any info?

Sim_audio_nerd,

Congratulations, please do give us some feedback when you can; would love to hear your experience. Mine has been a revelation, hopefully the same in your system

Teejay and all,

I am strongly considering purchasing the S5.5 in the next few days, and it will be paired with an Aric Audio Motherlode XL preamp I've ordered. I've already talked to Aric about the low 10k XLR values, and he is making a slight change to Motherlode to adjust for that.

I don't think this will be an issue, but just wanted to ask: Do you see any problems driving a "reasonable" pair of speakers. I know the Clayton Shaw Caladans at 93db will be no problem, but I also have a pair of Thiel CS2.3 (4 ohms/87db....no lower than 3 ohms), and a pair of Buchardt Audio S400 MKII bookshelf (4 ohm/87db).

jonah5,

Thank you for the reply, sorry I didn't get back sooner....I was soaking up some sun on vacation. The more I read on the CODA S5.5, the more it made sense for me.....so I purchased mine, silver with gold buttons. I had quite a few conversations with Mike Kay at Audio Archon prior to pulling the trigger, and he really likes the combo with the Aric Audio Motherlode XL as well.

My CODA S5.5 just showed up late yesterday, and I unpacked it this morning. What a gorgeous beast it is, mine is silver with gold buttons (both are available choices). It is moderately heavy but actually manageable, huge heat sinks, oozes quality, and I didn't expect the WBT highline connectors.

I'll put it into place of the Denafrips Thallo amplifier this afternoon, and allow it to break in along with the Clayton Shaw Caladan speakers. I'll try to get some early thoughts together in the next day or so.

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.

firefly627s,

My only experience with Klipsch speakers is in other people's systems, and I've mostly been unimpressed.....but that may very well be the accompanying electronics. Twice they were being driven by a "mainstream" amp (can't remember but Technics/Onkyo/Sony/or the like). The one time I was impressed, my friend was driving a pair of Cornwall IIIs with a Tubes4hifi VTA ST-120 tube amp......which I later purchased and still own. But I don't own Klipsch and certainly have no extended experience with them.

Markmuse, I never did see anywhere that you posted your opinions on the Caladans since you got them.....I'd love to hear from you on them. Send a private message if you don't want to hijack this thread.

I loved the Backert Labs Rhythm 1.4s that I test drove a few weeks ago, it came down to those and the Aric Audio Motherlode XL for me.....but the Backert was absolutely terrific.

I'll try to get some thoughts together on the CODA/Caladan pairing, but it's 73 degrees and sunny here in Chicago today....and my wife has me cleaning up around the house today (and basement). She's definitely putting a "hitch in my getalong"....but she never complained about buying the Caladans/CODA/Aric Audio, so I owe her.

christianb5s4,

After much consideration I looked at several tube preamps: Backert Labs Rhumba Extreme 1.4, BAT VK-80, Rogue RP-9, used Audio Research REF 5SE, and Aric Audio Motherlode XL....and had previously looked at Atma-Sphere MP-3, LTA MircroZOTL, along with a few others. The LTA MircoZOTL does not have XLR outputs, but does have XLR inputs.

I found the Backert Labs Rhumba Extreme and the BAT VK-80 to be favorites, thought the BAT was out of my price range....my friend however did buy one.

One thing to consider is that the CODA S5.5 has an input impedance of 10K Ohms on it's XLR outputs....which can be troublesome. I ended up purchasing the Aric Motherlode XL preamp, and Aric is modifying it's circuit to work with that 10K Ohm circuit. The Motherlode XL has 2 sets of XLR inputs, 2 sets of single ended RCA inputs, one XLR output, and one single ended RCA outputs.

I'd reach out to Aric 413 627 2543 to have a conversation about the S5.t combination, he's a GREAT guy to talk to, and is very helpful. I know he's created several Motherlode XLs for clients that will end using them with CODA S5.5s.

I also purchased my CODA S5.5 from Mike Kay at Audio Archon, he's also a great guy to talk to, and carries several tube preamps.

Teajay,

I didn't have a chance to compare the Motherlode XL with the Backert, but the Backert Rhumba 1.4 vs the Rhumba Extreme 1.4.....that's why I suggested the demo between the two if near a dealer. The Rhumba Extreme 1.4 would have been my choice had I not gone with the Motherlode XL.

I'll have some short listening notes on the CODA S5.5, I've been able to get about 10 hours listening on it so far.

yyzsantabarbara,

Give Doug Dale at CODA a call, I spoke to him a few times and he was helpful and great to speak with before I bought my CODA S5.5. I don't want to speak for him, but I think he'll suggest the #16 vs bridged S5.5s

Minotophase3,

Congratulations, you will love the S5.5! I'm driving 93db 4 Ohm Clayton Shaw Caladans with it, and the Spatials should be amazing as well.....love my combo

minatophase3,

I am currently using a Denafrips Hades preamp, which surprisingly has not been a bad combo with the CODA S5.5. I initially thought it would be totally outclassed, but it's held it's own so far....but yes more performance is there to be had.

I have an Aric Audio Motherlode XL preamp on order right now, should be about 6 weeks out by now (intially 12 weeks)? I spoke with Aric about the 10K ohm XLR issue, which is the very edge of the Motherlode's comfort level....and he is modifying it for me to be good with the CODA's low XLR load.

So far I have not bothered with the stand by as I don't mind burning it in a bit more. I spoke with Doug Dale at CODA, and he said the S5.5s get about a week burning in before they are shipped.

I have no personal experience with the Serene or the MicroZOTL (though I considered it), but the Rhumba Extreme 1.4 is the real deal. In the end I chose the Aric Audio Motherlode XL, but it was not an easy decision....it's really good.

Jfrmusic,

Call Doug Dale at CODA, he is easy to talk to, free with his opinions, and an all around great guy. I've spoken to him a few times before and after buying the S5.5, and he was easy to reach.....actually he picked up the phone each time.

He'll be straight with you and give you an honest "yay" or "nay". He probably can give you a better understanding of the correlation of WPC compared to current delivery than most of us can

+1 for speaking with Mike Kay at Audio Archon. He's a great guy to talk audio with, and he carries some high end brands including CODA and Harbeth.

What was really helpful to me personally, was that Mike is friendly with Aric Kimball of Aric Audio and he was helpful in talking through the pairing I ended up with: Aric Audio Motherlode XL and CODA S5.5. His prices are also more than fair, even for new equipment

laginz,

Sorry I seemed to have missed your post. Currently with the Denafrips Hades preamp > CODA S5.5 > Clayton Shaw Caladans, the soundstage is more similar to what I would consider a live performance. Soundstage is outside of the speaker width maybe a foot and sometimes more. The vocals are front and center with instruments in their location, and the whole presentation comes from a "platform of sound" and not from the speakers themselves. I have not noticed vocals coming forward of that stage, but I may have just missed it if it does.

One of my favorite bands Poi Dog Pondering is a collection of 8 to upwards of 16 musicians and vocalists depending on the track, and I have never heard them properly placed in a recording before.....at least compared to live performances where I have seen them more than a dozen times. Also the instruments all have their own audio space as well, being able to pick out synth, from electric violin, to recorder, to horns, to xylophone, to accordian, to harmonica. The CODA and Caladans do this for me.

I don't tend to listen to a lot of small presentations with minimalist vocals or instruments.

Off topic for you streamers, I'd recommend listening to a couple of albums from Poi Dog "Wishing Like A Mountain, and Thinking Like a Sea", "Pomegranate", and "Natural Thing".....may or may not be your cup of tea, but a real workout for a system.

I'm gonna try and get my thoughts together and get an opinion posted here in the next couple of days. Had to do extra work, because I was also breaking in a pair of Clayton Shaw Caladan speakers.....and needed to make sure what I was hearing was the CODA and not just the Caladans breaking in.

Sorry for the extra long delay in getting my CODA S5.5 notes out, but things have taken longer than expected. Not only did I receive the CODA, but my Clayton Shaw Caladans have been breaking in at the same time (about a month old); and I wanted to make sure my notes reflected the CODA as much as possible. To help with that, I have been going back and forth with my Buchardt Audio S400 MKIIs which I have had for two years.

My notes are a combination of: Audiolab 6000CDT transport, Denafrips Pontus II DAC, Denafrips Hades preamp, and CODA S5.5 amplifier….back and forth with the Caladan and the Buchardt speakers. Also my current listening room and speaker position is not ideal, so I’m sure it is affecting bass/soundstage. Parts of my notes are re-posted from my original Caladan review....as they apply

 

Music used for critical listening (all CD, whole album listened to): Poi Dog Pondering “Wishing Like a Mountain and Thinking Like a Sea” & “Pomegranate” – Eagles “One of These Nights” – Nirvana “MTV Unplugged” – Chris Isaak “Heart Shaped World” – Gorillaz “Demon Days” – The Talking Heads “Stop Making Sense Remastered” – Chris Stapleton “Traveler” – 10,000 Maniacs “MTV Unplugged” – Johnny Cash American IV - Supertramp “Crime of the Century” – Dire Straits “Brothers in Arms” – Memoirs of a Geisha “Soundtrack” – The Civil Wars “Barton Hollow” – Atlanta Rhythm Section “Champagne Jam” – Amy Winehouse “Back to Black”

Several of the albums I chose for their difficulty. Some can be bright, some can be congested (Poi Dog sometimes up to 16 musicians and vocalists on stage), some to get a variety of genres, and some because I just love the album.

First impressions of the CODA: It’s beautiful, solid, well made with high quality components (didn’t expect the WBT fittings), a statement piece…..mine is silver with the gold button option. It’s relatively easy to move this amp around, which was unnerving at first, “there’s no way this amp can produce much power” was a thought that did waft through my head. A couple of buttons for bias (turns on components) and input selector, and 3 LEDs….simple, elegant. I installed the amp using a newly broken in Zavfino Majestic OCC 12 AWG power cable, with Morrow Audio MA4 XLR cables from the Hades preamp. Speaker cables so far have been Anti-Cables 3.1 which I know really well, and are fully broken in.

This amplifier is dead nuts quiet. The background is black, and music comes from a much lower base compared to the Denafrips Thallo that it replaced. Listening at lower more comfortable levels is really enjoyable since the difference between black and even lower levels is more dynamic than I’m accustomed to. Crank on the volume and more is more, not just louder more SPL  reveals more information in the recording. Relaxed loudness? I did crank it up past my comfort level, but all I got was more really loud gorgeous sound. The amp also never ran hot, certainly not uncomfortably hot….even when pushed to my discomfort level for a full 5 minutes or so.

Bass: is punchy, quick, tight, detailed, and effortless…..never ever sloppy or slow. Deep bass is delivered as needed, but I’m not going to be the final voice on that; as neither the Caladans (yet) nor the Buchardts are going to dig really deep down, but I have no reason to believe the CODA won’t be up for the task. Transients are quick and very dynamic, there is nothing slow about this amp at all.

Midrange and highs: Holy shite!

Now we are playing to the strengths of the Caladans and Buchardts, but this can only be explained as magic, joy, happiness, and whatever descriptive I can think of. Vocals are Ethereal, is the word I’m looking for that I haven’t used before. Oxford definition “extremely delicate and light in a way that seems too perfect for this world”. What a wonderful tone, liquid, vocals are detailed and show every piece of frailty, grit, nuance, breath, emotion, intensity (Chris Stapelton, Natalie Merchant, Johnny Cash, David Byrne, Mark Knopfler, Amy Winehouse, Bruce Springsteen). Vocalists have their own distinct space and separation (multiple vocalists), hang in the air, and completely separate from the music itself. Presented more like what would be common in a live performance, nothing is muddied together.

Highs are extremely detailed, airy, and you get the beginning and end of notes….decay is noticeable which I often find hard to notice. One thing that this amp delivers is the ability to “un-jumble” detail, especially on complicated music; with lots of vocalists and musicians present. Every musician and vocalist is present, and separate, and available. More like a live performance where each has their own space on stage and in the performance…..except in a recording.

All of this “extra” in vocals and highs comes with no harshness, or sibilance, or edge. The music is more “alive” than I’ve heard in my home, and more what I hear in some of my audiophile friend’s systems that are north of $100,000/$200,000……and certainly not in a $25,000 system.

Presentation: Soundstage is wider despite the less than perfect room, going a couple of feet outside of the speakers. Height is there as well, better than normal……and finally some depth. I am positive this will all be improved when I finish my dedicated listening room sometime this year. I’ve said this before regarding the Caladans, but even more so with adding the CODA; the music just seems to be presented from a “stage” of music, and does not come from a pair of speakers. The speakers do not completely disappear yet, they are still there….but I can see me getting there in a better room.

The CODA S5.5 is a great addition, and upgrades every single audio aspect versus the Denafrips, and even my Tubes4hifi VTA ST-120 tube amp. As you can tell from the above, I am in love with this amp and what it has been able to do in my home. It plays extremely well with both the Buchardt and Caladan speakers, but the Caladan pairing has a special synergy that brings out the best in both…..bringing each more alive.

If you take this as a hype piece without any honest opinion, I’m sorry as that is not my intention. And yes there are improvements to be had, but I truly believe that getting to my properly built, properly dimensioned, and treated room will yield those results. REMEMBER that we are talking about a $6,400, 45 pound class A amplifier here that is attainable for most audiophiles…….this is not some esoteric $50,000 200 pound beast. How can I not be enthralled, my last two purchases (Caladan and CODA) yielded exactly what I wanted and had hoped for….even more

At this point I am still using the Denafrips Hades preamp, which is WAY better than I ever gave it credit for….amazing performance for a $1,400 preamp, and fully balanced as well. But it will soon be going up for sale, as I’ve got to make room for the Aric Audio Motherlode XL which should be here in about 4 weeks, and I cannot imagine what that final pairing will be like. I’ll probably not be able to give a detailed review once that is in place, I’m out of superlatives.

 

sim_audio_nerd,

I look forward to your thoughts, be nice to hear from another set of ears

Teajay,

To add to my insanity recently, I also made a decision that has put me in the dog house with my wife. I was on Aric's Facebook page, and noticed that he had one of his Transcend "push-pull" amplifiers up for sale at a really nice discount. This was the same unit that Bob Grossman reviewed for "Enjoy The Music", except Aric is upgrading the caps to Jupiter Copper foils, which he said really transform the amp even further. I'm really done for a while, can focus on building my DIY power and speaker cables that have been waiting for me to complete....and breaking in some equipment.

 https://www.enjoythemusic.com/magazine/equipment/1223/Aric_Audio_Transcend_Push_Pull_Amplifier_Review.htm

I bought mine from Mike Kay at Audio Archon near Chicago, great guy to deal with.....but have no idea on return policy

tabl10s,

Looks are incredibly subjective of course, but I find the CODA S5.5 to be very appealing. The performance of the S5.5 is stellar, and aolmrd1241 said......you'll be missing out on an amazing sounding (and relatively inexpensive for what you get) amplifier. I'm excited every day to put on a new CD and listen to the CODA/Caladan pairing.....a great match

Teajay,

Got some good news this week, Aric Audio is shipping my new modified Motherlode XL preamp! It will be a little while for me to reconfigure my setup, but really looking forward to hearing the CODA S5.5 and Aric Audio Transcend "Push Pull" amp through the Motherlode.....lot's of fun listening ahead.

sim_audio_nerd,

I just looked up your Supratek Grange Signature, that looks like a beautiful beast! I'd love to hear your comments once the CODA shows up

sim_audio_nerd

Thank you for the review, and yes your findings are roughly the same as mine.....both with Buchardt Audio S400 MKIIs and Clayton Shaw Caladan speakers. I do agree that a better dedicated listening room would improve soundstage depth and width, as my current space is not ideal. I too am really surprised how cool the amp runs, I thought it would be much hotter.

I'm now driving it with an Aric Audio Motherlode XL preamp.....this combo is ridiculously good, as I'm sure the SupraTek is. Glad you're enjoying it....and yes, thank you Teajay for bringing the amp to our attention....I never would have know or considered the S5.5 otherwise, as their other amps are just not in my budget

fthompson251

I know waiting around for new gear is no fun. I waited 3 months for my Clayton Shaw Caladans, and almost that for my Aric Audio Motherlode XL preamp. But I personally would rather wait on a unit that was in such demand that people are clamoring for the product, because they are that stellar.

The Caladans, Aric Audio, and CODAs all fall in that category. Even more amazing that IMO they represent amazing value for money as well.

I was lucky enough to get my order for the S5.5 placed in February just after Teajay posted his initial impressions......when the lead time was only two weeks. I am sure that every second of your wait will be worth it for the CODA, it is truly a solid state revelation
