Building the Audio Note Kit 1 SET amp...


Hi, Folks,
If anyone's interested, I've started a blog with lots of photos, documenting my ongoing build of the Audio Note Kit 1 300B SET amp. If you've ever thought of building any kit before and want to get a feel for what it's like, you're welcome to have a look!

Mapman,
No, I've said all I am going to say about Tekton. It's a great speaker that will be overlooked by many. Too bad, go pay a few thousand more and good luck. Best.
Brownsfan, I believe, has both the DeCapos (Rebbi's) model as well as the Coincident Triumph, hopefully he chimes in and sheds some light from personal experience.

Mapman, the Tektons have no weird impedance dips, like dropping to 2ohms. It remains stable, never less than 6ohms. Did you read any of the reviews? Or my first-hand comments about the Tektons?

Tektons certainly don't enjoy ad-driven hype or Polo like labels; they just perform, and perform well with SS or low-SET.
Rebbi, Charles,

Understand. I think I thought I was beating a dead horse, glad the recommendation was well considered. Great that you had correspondence with Tim Smith, Eric and so forth. Rebbi, I think you made a superlative choice with the AN Kit-1. I believe everyone on thread was civil, attempting to be helpful. Great thread. Best.
If I had a vote I'd throw my hat in with Almarg and Charles' advice given the circumstances; plus I doubt SS can sound similar to DHT SET, I'll have to take Grannyring's word for that, but it must be ball-busting difficult to pull that off. I wonder how Brownsfan's 8 watt Coincident SET Dynamo 34SE is managing with the DeCapos? I have 95db 8 ohm Tektons that handle all music with aplomb. It's dynamic and goes as loud as I want it to in my 14x16 room. Rarely do I push the volume control beyond 10 o'clock which is loud, small club live sounding. At that anything past that volume my wife has to run out of the room. Good luck all this has been a great thread.
Rebbi,
There is a reason why Enjoy the Music, Stereomojo, Tim Smith, 6 Moons and his Wall of Sound review have given the Tektons (various models) high praise and Awards. Scott Hull in Part-Time as well, amongst many others. Those synth bass tracks would not be clipping with the Tektons, they would sound glorious; the mids and highs too.

There was a few years back an extremely long thread about the Tekton Lore, with many different A-gon members singing Tekton praises with over 10-14 pages of mostly positive comments. That is where these speakers came to my attention and I decided to take a flyer on them. So, now I own 3 models, the 4.5 monitors, M-Lore and Lore. They are very good, well balanced and would likely sound great with the An Kit-1 IMHO. You must read the various reviews and comments on these speakers, they reflect the truth(s) about these speakers. The Awards and positive comments are not hyperbole, or due to large ad budgets, but word-of-mouth praise by the knowledgeable audiophile.

The above mentioned reviewers have listened to the best equipment out there. They have given the Tektons high praise. I hate saying it this way, but so have I. I've been fortunate to have owned or listened extensively to some great speakers, starting with my parents big Tannoy, KLH9s, Bozaks, JBLs. Since college, Dynaco A25, Advents, more KLH, Yamaha, Heil, Walsh, Spendor, Magnepans, Quad 57s, Rogers LS3/5, Kef 104, C30 and C40, I believe, Vandersteen 1Bs, 2CE, Sound Dynamics 300ti, Infinity, Harbeth, Fried, too many to list. My point, the Tektons with 93-98 db efficiency, easy 8ohm impedance, great bass down to 34hz with the Lore, lower with some other models, low relative cost, is an astoundingly great gift to the audiophile, especially those with a moderate budget or low-power SET amps.
Charles,
The tonality and timbre, naturalness are there, again, read the various reviews. Both Tim Smith and Scott Hull are thorough reviewers and speak plain truths as I know it with the Tektons.

Grannyring, I played bass guitar during the 60s Rock era, and unless you want to damage yours ears, a quality 8-20 watt SET tube unit in a 14x16 room with a well designed and implemented high efficiency speaker such as the Tekton and others will rock the room. If you want stadium Rock, to fill The Boston Tea Party venue or Fillmore East/West then you might want something else. Remember, Rebbi’s room is something like 11x10. What's your goal? Animal house, or musicality in a small room? But also remember that large movie venues were filled with sound using old, low powered Western Electric amps.

Rebbi, Eric Alexander is a special designer/builder. His Tekton likely would suit you. My brother has the DeCapo's (your model) as well as Harbeth HL5. I've listened to a number of Omega's, nice workmanship, but to my ears not up to the Tekton, hence, I purchased the Tekton 4.5. I hate to keep banging the Tekton drum, but they are outstanding, especially at their price points, but don't let their price points fool you, they play with the big boys, and better than many.

Mapman, I don't recall ever hearing Tuetons; but I did love your old employer's place, Tech Hifi in Paramus, NJ. That is where I met John Rutan for the first time. As you probably know, John owns a great brick and mortar in Verona, NJ. I like to think of him as "The Gentleman of Verona". John, early on, helped me make some good musical choices. One of the good guys in the trade.
By-the-way, John also helped build a nice-sounding system for one of my bother-in-laws around Vandersteen speakers. Great shop, so few left.
Mapman, with a low-end that only reaches down to 58hz why would Rebbi want this speaker? the deCapo goes deeper and is better all-round. Rebbi's small complaint was that the DeCapo did not capture the lower octave on stuff with Synth bass with his 300B. The Heresy is even less capable in that regard.
From reviewer Tim Smith: So what do the M-Lores sound like? They don’t really have a distinct signature. They are more or less neutral. Seamless and well balanced. They can sound relaxed. They can sound energetic. They can sound warm if the source material is warm. The M-Lores image wonderfully. Given their low height, I thought I might elevate them on paving stones. There was no need. The sweet spot is large, left to right and vertically too. Room placement is not difficult. I have mine six to eight feet from rear walls and the bass output is prodigious, even with tube amps. The sound was just as good when they were closer to the walls.

The M-Lores are detailed without being bright. They are fast: the opening of the second movement of Ravel’s Piano Concerto in G will jolt you out of your seat! Holy dynamic swings, Batman! And speaking of one notorious bat man, Calvin Broadus’ driving backbeat will glue you to your seat. This amp loves rap and reggae. Peter Tosh’s “Mystic Man” is electrifying through these speakers. From the sublime to the ridiculous, the M-Lores can do it all. They can capture Louis Lortie’s hypnotic reading of Debussy; they can bang out with Snoop D. O. Double G. Sorry, Snoop Lion.
More from Tim Smith: These small speakers are a bass-head’s dream. They are fast and rhythmic. Even with a single-ended tube amp putting out 5 watts, they have floor-rattling bass. They handle Steve Swallow’s electric bass with aplomb; Brian Ritchie’s bass on “Please Do Not Go” (Violent Femmes, self-titled LP, Slash Records) has never sounded so taut, so dry, so textured, so nuanced, so visceral. I listened through the Audio Research LS17 and Wyred4Sound SX-1000 monos. It was breathtaking, among the very best recorded sound I have heard–anywhere, anytime. I had the same reaction when I listened to The Jimmy Giuffre 4′s LP “Quasar.” This is an eclectic, electric, spacy, funkadelic jazz recording that has languished in obscurity for too long. It deserves to be seen on par with Herbie Hancock’s classics “Mwandishi” and “Sextant.”
And just a little more from Tim Smith: The M-Lores are so good, I almost sold my Harbeth Compact 7s. The 7s, including their dedicated Skylan stands, cost more than four times as much as the M-Lores. In some ways (bass, the ability to play loud, dynamic swings), the M-Lores are better; in most ways, it’s a tie. For a good month after receiving my Lores, I was under the spell of Tektonite for many a night, and my Harbeths stood lonely in the corner of my man cave. I keep the Harbeths because they nail vocals and the sweet tone of a guitar like no other speaker I know.

Three cheers for Tekton Design for bringing a slice of the high end within reach of the majority of the population. As other reviewers have noted, the cost of the parts that go into this speaker, were they purchased straight off the shelf, would total over one-half the retail price. Not only are you avoiding lining the pockets of middlemen when you buy straight from Tekton Design; you are not being fleeced by the owner/designer either. These are fair prices. There cannot be much mark-up here. For this reason, and due to its addictive musicality, the M-Lore is surely one of the best buys in audio. Highly recommended.

Yeah, me too, agree completely! Take the sixty (60) day trial. M-Lore.
Read: Magnepans (3.7) AND TEKTON MEET PASS LABS, ODYSSEY, JOB, MERRILL, RED WINE AUDIO, FIRST WATT AND VITUS AUDIO: From Confessions of a Part-Time Audiophile

Yeah, according to the article, Tekton (Pendragon and Seas) can go head-to-head, toe-to-toe with about any speaker you may like using amps wearing big-boy pants.

Bottom line, according to Scott Hull: they are excellent.
Rebbi,
If it was me, I'd keep your magnificent AN Kit 1 and DeCapo's. Do you really miss Tecno Synth bass in most of your listening? I'm usually happy with speakers that can capture the low E-string on a bass guitar. In your small room most Rock, classical, Jazz, voices, etc. should be excellent with terrific tone, timbre, naturalness, and all the other attributes of 300B sound. Why invest/spend huge amounts to capture synth bass techno sound at the expense of your other 98% listening?

On another note, after reading all of this thread, my wife exclaimed, I am still building the AN amp, I love the sound of the 300B tube. So, there you have it, I'm one lucky dude. Coincident Dynamo in my office, soon to be Coincident 300B in my dedicated listening room and AN Kit-1 in the living room. Retirement is going to be fun.
I always understood the latest discussion was about dynamics and not loudness. Being a bass player in Rock Bands as well as performing as a studio musician for a limited time I know dynamics and slam. I think that the Tim Smith articles on dynamics with the Tektons mirror my own experiences with the Tektons and low power tube amps including SET; they do dynamics startling well. If you want concert-level volume and dynamics in a normal house, or room have at it, pay the price of admission and be done with it.

What we are discussing here is a family man with about 11x10 listening room, and like most people with a family, limited resources to allocate to the high-end of audio. I believe Rebbi has done a stellar job separating the chaff from the wheat demonstrating remarkable ability to put together an Everyman high-end system. We truly need more of that example.

Suggestion for speakers ought to be of high quality all around, that best fit
in with creating a properly balanced, synergistic system that also fits a budget.

My audio bias falls in the camp of tone, tone, more tone, timbre, natural musical flow, richness, liquid sounds that get a piano right, as well as all the other instruments, just like real accoustic life, a good stage, coherence, natural decay, PRAT, male and female voice front and center with height and dimentionality, as well as all the other goodies. If I miss a smidgen of slam, ok, it costs too much, but the Tektons amongst others come close, very close. So given the goody bag cost which do you prefer to lose?
Charles,
You make terrific points on topic, Rebbi had high power, as did I about 14 years ago with bel canto, loved their dac's back then, but not the amps. Bought the Cary V12, Audible Illusions M3 and the Golden Tube 300B. Really nice sound all around.
Rebbi, Charles is right as Almarg pointed out, the DeCapo's are likely 86-87db. Get a true 93db or above and everything will get much, much better. And GSM is also correct with his observation that guys like the Zu fellows, Eric at Tekton and many other smaller company designers/manufacturers bust their collective behinds to stand by their product and help their customers. It's daunting, many fail despite good quality products. At any rare, quality over quantity for me and I still am antsy to read Rebbi's further observation and comments.
First, I completely agree once again with Charles1Dad.

Second, Rebbi, you confuse me. On the one hand you now have a system where you state that the low end is surprising you (yet the Manley had a little more grip), ok, understand that, then you state you'd like a little more efficient speaker, ok, understand that also, then, you say you were listening to something familiar this morning that gave you chills, musically captivating, ok, understand that. What I don't understand: I thought you had a constrained budget, hence I wasted a lot of time writing about a great bang for the buck speaker that is similar to the DeCapos, only more efficient (by a lot) with solid bass foundation that certainly, by all accounts, competes with $5,000 speakers. I know I would have recommended to you other speakers if I knew your budget was several thousand dollars plus. So, what is your budget? I feel a bit foolish, sounding like a Tekton salesman when I have no connection to them whatsoever. And, if the music is captivating, giving you chills on music that you mostly listen too, then are you going to actually throw that away for a type of music you don't often listen such as Techno Synth Bass?
First, let me state that I love the blog, it inspired my wife as well. This discussion has been a most enjoyable thread, as was your thread that started this one on best bargain SET. These threads are amongst the best type that Audiogon has to offer with knowledgable friendly posters' (you know who you are).

Keep in mind that most of us are truly well-intentioned, want the best outcome for you; we understand that your choices will likely be different than our own, but we make an attempt to guide you to good possibility, to narrow choices from our personal experience, or something promising that we came across.

What I found frustrating more than irritating was that I thought we were operating in a parameter of suggesting/finding a speaker that would play well in a small room (11x10), with the type of music you typically listen too with limited budget ($2,000 or so). So, given that the conversation started drifting to upwards of $3,000 I felt I wasted a good deal of time working with the above parameter since higher price points bring more options to the table; hence, wasting my time banging the drum for a particular speaker, at a price point that performs as well or better than many speakers at $3,000 or above. Yeah, it was frustrating, because in my case I was looking for the reviews, cutting and pasting, attempting to bring points of view from some industry professionals to back my suggestion. It wasn't merely a extemporaneous respone, try speaker A, it's good blah, blah...there was some corroboration and research, plus I own the speakers. Then we are talking about speakers costing much, much more, hence the wasting my time comment.
Rebbi,
There is a Zu vs. Tekton thread on the Audiogon. It was a couple years ago and was very good, a lot of posts pro/con back and forth. If I can summerize it overwhelmingly came out in favor of Tekton. The Zu's apple to apple cost much, much more. Do yourself a favor and look it up. I believe it started by a fellow named gpowered. Many A-gon regulars posted.
Brownsfan,
Your eloquence, kindness and clear thinking is truly what helps make threads like this, Audiogon, worthwhile. Rebbi has a huge rooting section here, he has stimulated outstanding conversation. I look forward with great interest to the next part of your blog.
Almarg, thanks I've always understood all that. That's why l've pushed for Rebbi to consider a higher efficient speaker like Tekton or others at his price point with the added benefit of better/lower bass. There won't be any clipping with the Tekton Lore, 98db, benevolent 8 ohm load, 30hz bass. I'm getting that right now (listening to John Mayall's Blues Breakers with Eric Clapton) with no clipping. That is with the little Coincident Dynamo 34SE 8 Watts. And I am playing this LOUD! In a 14x16 room. Earlier, I was playing Lorde, I believe a cut that made Rebbi's system clip. No problems here, played it loud enough to chase me from the room.
At any rate, when Rebbi trots over to Sebrof's place he can settle for himself whether or not the Tekton works for him with the AN Kit 1. I've grown tired of this dicussion, I don't have a dog in this fight, just trying to be helpful.
I believe Sebrof still owns the Tekton. Maybe he will chime in. Or, you might read his comments on the old Zu vs Tekton forum discussion?
Rebbi,
What you say about snickering on Parts Connection is what bugs me about the so-called audiophile community. What they ridicule can be said for 85% of their own equipment that they purchase. If they can do it so well why don't they have the guts to manufacture and give a quality design at an Everyman price point? Let's operate in the cliche way, step on someone's throat to elevate one's self. They have no understanding of the difficulties being a small business. They may claim too, but don't actually.

Personally, I've owned a reasonable amount of expensive audio equipment.
From my experience the Tekton performs in a stellar manner. YMMV. As cliches go, every model punches way above it's weight. Did you actually read Tim Smith's review in 6 moons or Wall of Sound, Positive Feedback, Stereomojo, Enjoy the Music, Part-Time Audiophile and other publications? Are their writers honorable and truthful, or the opposite? Why has this speaker bran garnered so many recent rewards and rave reviews? The owner of Tekton certainly isn't spending big ad bucks in Stereophile or The Absolute Sound. No, the reason that Tekton has gotten some attention is they happen to be musical and do the audiophile stuff in a splendid
manner at a reasonable cost.

Some folks appreciate what it takes to accomplish that while twits snicker. I say hooray for people like Israel Blume and Eric Akexander who have provided the audiophile or anyone interested in music with quality products to exploit the music.

Instead of snarky snickers people like Blume and Alexander ought to get cheers. And they are by word-of-mouth, getting awards from quality writers and their publications.
I would also like to add that I would get the Lore. Also, I hope Sebrof has the Lore, not just the Katz Meow model. Apples to Apples would be best.
Thanks Charles, for some good perspective. I know and have stated that tastes vary, results vary, the same exact equipment, different room, different result. Some audiophiles need to buy expensive well-known labels even though there is better out there that is less expensive.

Some folks cannot separate hyperbole and fluff from a lot of audio writers and ad bucks, then when something darn good comes along with low or no ad bucks, suddenly these same folks come from Missouri, "the show me state". I suspect the low-cost of Israel's Dynamo and Eric's Tekton scare many people away because of lower cost. These type of folks need a prestige label with well-known bragging rights, likely vastly overrated, cost three times or more than what it should.
Wow, it's going to a cliffhanger of suspense!

Sebrof, thanks for chiming in. Do you still enjoy the Katz? Were you trying to sell them a while back? Enjoyed the threads you participated in, but haven't seen many posts from you lately. Good luck with all your endeavors. I'm guessing Rebbi goes in a different diection entirely.
Rebbi,
This is good news really. It will be fabulous when the issue is resolved, likely you will not need to purchase new speakers. Then you might consider the benefits of a new power cord, something like the Black Treasure 300B. On sale now at Parts Connection or Grant Fidelity. Good luck. Shabbat Shalom.
Almarg, as an aside, do you have any thoughts about the ability of the Coincident 300Bs driving any of the Daedalus speakers?
Hello Almarg,

Thank you so much for your thoughts. I was once a heavy blues Rock n' Roller, but today I mostly listen to symphonic classical, London, Living Stereo, Decca, Telarc, etc., music from the movies, plus smaller chamber music, Jazz, 40s-50s male-female vocals such as Ella Fitzgerald, Louis Armstrong, Duke Ellington type groups, accoustic folk, and a fair bit unusual groups similar to Loreena Mckinnet, Dead Can Dance, Mediterraen instruments. Of course I stll play Muddy Waters, Howlin' Wolf and the like, Harry Belafonte, Sinatra, Martin and similar.

Daedalus is on my short list along with DeVore Orangutang 0/96, Line Magnetic WE 755, Coincident, Tannoy Prestige Line and do on.

Best, Rob
Thanks everyone.
Rrsclyde, thanks for that info.

Charles, on one of my trips to NYC and/or Los Angeles, I'm going to set up appointments to hear the Line Magnetic 755 Field Coil. I will absolutely write my impressions here. I also really enjoyed the VAC the times I heard them, also 30/30. Best all, Rob
Rebbi,
To me you didn't seem that open to Tekton during the thread so of course I'm happy you got to hear a pair even if not the latest incarnation. You really owe it to yourself to hear the Lore or M-lore if you must change from DeCapo. I get the impression you didn't believe or trust Tim Smith (6moons) Scott Hull (part-time-audiophile) Robinson and others from Enjoy The Music, the Positive Feedback, Stereomojo stuff, Awards from publications, or first-hand experience from some folks on this thread. Granted, there are many fine speakers out there; but not that many quality brands with high efficiency and benevolent impedance for low-powered tube, especially SET at 8 watts at less than $2,000 with a bottom end that extends to below 40hz. Also, I don't normally
push as hard as I did for a particular speaker because one begins to sound like a one-note pony, perhaps with a connection to the company, or you sound like salesman. If you had six thousand bucks or more my recommendation might be different. Maybe not. As Enjoy the Music and other reviewers have pointed out, for example, the Tekton Pendragon can go head-to-head with $20,000 speakers. I believe I gave you an honest assessment from my point of view and your equipment choice/budget. I'm gonna' try hard not to mention Tekton again as this thread continues...
Smith certainly got my attention. I believe he is among the best Reviewers out there, extremely complete and thorough. That Coincident review was so right on to these ears. I ultimately, after much listening, switched my preference from the Sylvania 6SL7 WGT Mil Spec to the RCA Red Base 5691. His Tekton, Wall of Sound review was frankly, another well written accurate piece of review journalism. Kudos!
Sebrof, you are a kind person, kudos to you too!

Charles, all you state is true. The small guys that create superb products in audio have a huge upward climb. Many can't afford to a attend the major shows or place ads in publications. In the small shops like Eric's, who builds the speakers and runs the business while you're gone? Any small mis-step can ruin these types of company.
As the drama builds seriously consider an upgrade to the Psvane Black Treasure 300b tube. Now only about $284.00 a pair. But first, listen to what you have, enjoy. Can't wait.
Rebbi,
I got my Stereophile mag today and Herb Reichert does a review of the Tekton Enzo XL. He basically raves about them. They cost $2,200 and play with the big boys according to him. LF down to low 30, can do it with 3 watts of 2A3. I just picked up my brother's 3A DeCapos to compare against the M-Lore and Lore in my system at my place. Give me a week or so and I will report back.

My gut tells me you'll soon get to the bottom of problem and the AN Kit is going to be more than superb with the deCapo. Best
Charles, I really like and enjoy the DeCapo's; but I have only heard them at other folks homes. I have listened to this speaker at my brother's home many times and in shootouts with our mutual friends. The DeCapos are in brother second system. His main rig is Harbeth HL5/Leben.
Rebbi,
Yes, our family has always had great audiophile stuff. Both brothers currently. Sister no. Father and uncle, many big name pieces in a bygone era, KLH Electrostatic 9s, Marantz 7, 8b, Big MacIntost, Bozaks, Garrard 301, Thorens, JBL, plus many more...thousands of records. Wish I had all this stuff today. My first serious listening was with Quad 57 speakers, tube set-up, getting schooled on big-band Jazz of the 40s.
Congrats Rebbi,
It won't be long before your home is filled with music. Brian and Pete should be commended for superb support. Best.
Rebbi,
By-the-way, the Enzo Reviewer (Reichert) favorably compared the Enzo to the DeVore Orangutang O/96. As I've previously mentioned on this thread I am currently comparing my brother's DeCapo Ref 3A against the M-Lore using the Coincident Dynamo 34SE 8 watt amp in my room and set-up. I will make one comment at this juncture. The bass on the M-Lore is much, much better in quantity and quality. YMMV. Best.
Charles,
Yes, have them all on various records or cd. I was listening to LeRoy yesterday with Chet Baker, then later with Ben Webster. I like it that he also did the Doors and Van Morrison on some numbers.
Smctigue1,
The bass is good, just not as good as the Tekton. I'm in the middle of comparing the M-Lore against the DeCapo in my room, my ears. Overall the DeCapo is very nice with the Coincident Dynamo 8 watts across the board. I will go into detail at a short future date. I am going to, at some point also compare against my Lore. Going in I knew the bass should/would be better; but I'm interested to find out how they compare in all other parameter, i.e., tone, timbre,harmonics, naturalness, soundstage, etc.
Smctigue1. I forgot to mention that I believe Rebbi will be in audio Heaven when he gets the AN-Kit back. I believe, as I listen, the Ref 3a and AN will perform superbly together, based on what I hear with the 8 watt Dynamo. The Tekton is also a great match.
Jet, Raylinds, Charles,
Your knowledge astounds me; it certainly leaves me in the dust. I suppose I'll learn a lot more as my wife builds the AN-Kit 1. I will be with her step-by-step during the build process. I know I really enjoy Alnico speakers as well. Perhaps we should also build the AN Alnico speakers???
Brownsfan,
With respect to your question above regarding the "Walking Bass" in comparing the DeCappo and Tekton M-Lore, here is my view with a little help from Wikipedia to sort out what I am trying to say, with the addition of my own personal take on the matter of the "quality and quantity" of the bass between the two speakers, I Quote (Wikipedia):

A walking bass is a style of bass accompaniment or line, common in baroque music and jazz, which creates a feeling of regular quarter note movement, akin to the regular alternation of feet while walking.Thus walking basslines generally consist of unsyncopated notes of equal value, usually quarter notes (known in jazz as a "four feel"). Walking basslines use a mixture of scale tones, arpeggios, chromatic runs, and passing tones to outline the chord progression of a song or tune, often with a melodic shape that alternately rises and falls in pitch over several bars. To add variety to a walking bassline, bassists periodically interpolate various fills, such as playing scale or arpeggio fragments in swung eighth notes, plucking muted percussive grace notes (either one grace note or a "raked" sequence of two or three grace notes), or holding notes for two, three, or four beats. Some songs lend themselves to another type of variation: the pedal point, in which the bassist holds or repeats a single note (often the tonic or the dominant) under the chord changes.

Walking basslines are usually performed on the double bass or the electric bass, but they can also be performed using the low register of a piano, Hammond organ, tuba or other instruments. They can also be sung. While walking bass lines are most commonly associated with jazz and blues, they are also used in rock, rockabilly, ska, R&B, gospel, latin, country, and many other genres.

A good example in classical would be the Walking Bass in the pedal part of baroque organ music (J.S. Bach's Nun komm, der Heiden Heiland, BWV 659, from the Great Eighteen Chorale Preludes):

In short the walking bass with the DeCappo is vague, lacking clarity, hiding in the shadows, missing in action, softer, as you stated above. With the M-Lore the walking bass is fully there, clear and present. More so with the Lore which reaches down to 30hz. On Jazz albums such as THE GREAT SUMMIT/Complete Sessions with Louis Armstrong and Duke Ellington, Deluxe Edition (Great Recording), Mort Herbert's double bass is so good with body, wood, buzzing, snapping, the M-lore gets it all. The DeCappo doesn't.
Charles, I see you know Jazz and quality bassists. Did you know many bass players have difficulty with walking bass when they first take up the instrument?
