Description

I am restarting a system on Audiogon just to let class D owners know there is gold to be mined in their systems. This is my H2O Laboratory. For over six years I strived to bring out all I could from the 16 bit CD. Finally, I think I learned everything there is to learn on how to match class D and H2O specifically to the most difficult speaker load extant.

I started this venture with unbridled enthusiasm. Having already heard great class A and AB amps on the Scintilla I knew how the speaker controlled the amp rather than the other way around. My first dally with Class D cleaned some of the thick solid state smudge. That was encouraging. I didn't care much whether it was musical or not in the beginning. I just wanted to hear what was on every CD. I didn't know then, how long a road of discovery it was going to be.

My beginning with the H2O six years ago was a rough start. I had to put up with preamps not made for the class D amp. My funds weren't overflowing putting two kids through out of state university. An Aleph P did a decent job. H2O make things OK by creating a class A preamp that not only worked with the H2O amp, but assisted the waking of the 1 ohm speaker too.

My sources were wanting back then too. I started with a Jolida 100 loaded with NOS Sylvania Black Plate tubes. Later I replaced that with an Audio Note One.1 DAC and a PSA Lambda. This combo allowed more of a the view through the CD window. I thought it was quite enough, until someone characterized the sound as being dark.

I sent the Lambda and AN back to H2O. They came back with cutting edge diodes that opened up all those highs I was missing, plus a lot of dynamics I didn't know I was missing. That sufficed for three years. The sound was extremely dynamic with full force surges that followed the biggest climaxing classical scores.

Cables were always a problem for me. I learned early on class D amps need shielded cables. The clip on iron rings did no good. Shunyata did good. Made up Belden wires did as well. All my gear is hooked up with Shunyata or Belden. I don't know why it works, but I do know it works well.

The speaker cable conundrum flummoxed me. I knew from experience insulation talks. Depending on the cable's thickness the insulator's sound will be a hiss to a shush. The only commercial naked SC I knew of was Speltz Anti Cable. After a year, I found out that they were lacking in the highs and lows, but had a killer mid. By listening to other's experiences I tried thin ribbon. That worked better than anything I had imagined. It just let every note through in it's fullest expression. The front to back depth popped into focus. Obviously all the CD's information can travel unscathed by the

Now, to bring it to present. My trusty Lambda transport died, and I became disabled.

I went on a search for a replacement for my Lambda. I was looking at older greats. They seemed to all upsample the signal before passing it on to the DAC. Some pre-filterred the music. I did not want any of that. Only one just passed the honest digital information.

There was one transport in my price range that did just that. That was the 47 Labs Flatfish and it's power supply, the Dumpty. This little jewel is better than I ever dreamed a transport could be. All of a sudden, I found the bass was not absorbed by my pliant 100 year old floor. There was something else, something that gave me dance fever. I looked up the Flatfish on the 47 Labs site. There I found what the transport's creator called the new ingredient in my system. He calls it, "Harmony." Whatever it is, it definitely takes the music to a whole new level of enjoyment. Suddenly, you just know that is what music should sound like. It isn't just low mid and hi notes it is the melodic interconnection of those notes that is missing in so many systems.

The Flatfish is coupled directly to the floor through the cabinet. My floor is suspended over a basement. I can feel all the speaker vibrations from the far side of the room where I am typing. Walking on the floor makes it bounce. How was I to keep the Flatfish from collapsing on it's unattached legs?

That is where I made the next big step. Like with the speaker cables, I had to invent something that would isolate the CD spinner. I looked at what was on the market, and saw there was nothing there that could do the trick to my satisfaction. So, I made one. It is perfect. It actually absorbs all the tremors and thumping the speakers make.

There will be no other changes. The lab is closed.

Components Toggle details

    • Forty Seven 47 Labs Flatfish
    A tiny slab of aluminum with a stainless screen skirt. The CD spins on top. Three loose legs gingerly balance the player. This is the best transport I have ever witnessed. It is a barebones transport with as few parts as possible. The laser and clock are fixed on a rail. The power supply, Humpty, is separate. It is a robust aluminum cylinder.

    The sound is better than anything I have ever heard. It is this Flatfishes uncanny to unleash a subtlety they call harmony, I just say it is the missing ingredient necessary to get the performer's real intention.
    • Audio Note UK DAC-2
    AN DAC 2.1 with diode upgrade - very important. This DAC sounds far better than stock AN DACs. The ultra fast recovering diodes let all the music through. CDs have it all.
    • Sanyo PLV Z-3000
    All the detail one could want, excellent contrast and near seamless fast action.
    • H2O Fire 2
    This is a muscular and pristine preamp. The dynamics, and dynamic surges are not approached by any other preamp. That I am sure of. Also, every improvement I make upstream of it is clearly passed on by the fire.
    • H2O M250SE
    An amp that will require advice how to bring out it's hidden perfection. This is what my site is going to be about.
    • Apogee Acoustics Scintilla
    This is the STOCK Apogee Scintilla - the original. My system will not work on foreign ribboned Scintillas. The Scintilla is a totally misunderstood speaker. Being 1 ohm and 76 DB, it takes a hurculean amp and preamp to master. That is what I have.
    • Speltz Anti-Cable
    I still have these on board because they have never failed to deliver what upgrades up stream I made. I also am using their brand new true digital cable.
    • Mother Lode Audio Gold Strike
    These are my own. I could not find any SC that could do it all. All commercial cables lacked something, and most of them emitted self noise. My cables are ultra thin copper ribbon for the positive, and aluminum ribbon for the negative. These deliver all what is fed them from upstream.

    Why use aluminum at all? Because this system proves it makes no difference what is used for the negative cable. The positive must be the best, though. That too is proved here.
    • Mother Lode Audio Cloud Nine
    The Flatfish transport is fixed to what it stands on. The floor in my listening room is a hung over the basement wooden floor. It bounces, and transmits every tremor to everything in the room, save the Flatfish. It plays perfectly without of hint of smear or skip. I accomplish this with a granite tile topped perfect cushion. This cushion absorbs all outside tremors and thumps. Need I say more? I won't.
    • Speltz 75 ohm digital cable
    This cable is nothing like their ICs or SCs. They are both stiff, and bendable. The Speltz digital cable is as slinky as a garden snake. It's performance is simply outstanding.

Muralman, Thanks for the offer for trying your cables. At the present time I am pretty happy with the cables that I am using. Henry is still burning my amp in and I will be most anxious to hear it once that I get it back.

Hopefully this latest review from 6-Moons will help get the word out and inspire others to audition Henry's products.

RLF, Good to hear from you. That was quite a review. I know the reviewer, and knew he is a champion of non oversampling DACS, so I knew the review would amaze readers. Please consider the sources I have and if you care to try my cables, I can arrange that. Henry is happily using my cables. Getting my source duo for trial, he used ellequent

Someone else linked the new 6 moons review to me. After reading it I was inspired to send my H20 Signature S250 off to Henry for the newest upgrades including the pure copper foil wiring in the power supply, Schottky rectifiers, an improved AC filter, and top-of-line Mundorf silver/gold bypass capacitors which will replace my V-caps. Henry now has it for the upgrades, but needles to say, I am anxious to get it back to see how it sounds.

It appears that Henry's great gear does not receive all the attention that it deserves which probably is due to lack of marketing hype, I suspect.

Have you ever made a technical climb of a mountain? It isn't a walk on an incline. It is the sum of many interim victories on the way to the peak. That is my model. This is the peak. There is no way from here but down.

Yours is dips and a peak. Funny image, but if it works for you, hooray.

muralman1

A peak is one that has nothing else on the horizon so beware of your logic: You view every small bumb you come acorss as a peak :)

In contrast, I have been through many dips and this is my first peak.

When the sound gets better with every change I make, I duly noted it. The reason I trashed my previous system site to start anew was because the trail I took was way too verbose. It was an evolution. I seem to have the Midas touch when it comes to audio. Below are some of the gates I opened on the way.

By the way, a mountain climber moving from peak to peak is a ridiculous analogy. My system does resemble a climber. But, if a neutral reader looks at this journey, it closely resembles a steady climb, from upper ledge, to and upper toe hold, to a crevice traverse, always looking up. The final surge to the top turned out to be an easy walk.

1 ohm Scintilla bought. The quest was to bring out the magic I heard years ago.

Big eyed Pass amps should do the work, if testimony was correct. I liked it.

The first improvement came when someone showed me how power cables can improve things. He was right.

Another Scintilla owner told me how he heard a class D amp and can't remember a better sound on a Scintilla.

I bought an early class D amp. I had an Aleph P preamp at the time. I had to turn the preamp's gain knob all the way to get a descent report. Sure enough, the music detail sharpened.

Henry got into the picture and built not only an extremely robust amp, but also a preamp made to go with it. The sound gained in clarity, and dynamics. It was a major breakthrough.

I changed my Jolida player for an AN and that for a better AN. That put everything into far better focus. I haven't changed the DAC save it's diodes. With the succeeding changes, it just proved what an amazing winner it is.

Tried Speltz cables. They were clearer than Kimbers I was using. I didn't doubt Speltz's assertion insulation clouds the signal. I later proved he is absolutely correct.

Later tried Speltz ICs. They made no difference. I kept them. They have proved to be as good as they need be given the final product.

On comparison with some new speaker cables with intelligent design against the Speltz wires convinced me I need to make a change.

Knowing how the Speltz cables sound very clear, due to the thin dielectric, I needed something that is just a bare. There was nothing that would do unless I wanted to pay thousands. So, I made my own.

Not knowing what to expect, I devised thin ribbon cables. The difference was so astounding, it knocked me onto the seat of my pants as soon as I inserted a CD.

There was no reason to think a change in my transport would improve things. It had been compared favorably in a shoot-out amongst half a dozen others. It died.

Enter my last component change, the 47 Lab flatfish. I love their philosophy, because they believe in leaving the music alone as much as possible. Now the sound is way beyond anything I had hoped for. The music gained in several ways. Separation was exact, timbre perfected, voice live, attack frightening, exquisite highs, and everything is tied together in a perfect harmonious flow.

It simply amazes me what all the lowly CD has buried in it. With the right CD, one that makes use of the full bandwidth, and the total dynamic range, the music will take you and spin you around.

Henry was so amazed he now is talking seriously about entering a show. He knows exactly what I am listening to, because his system is a mirror image of mine (while he has my source duo). All my components are presently available on the market, except the Apogees. Henry thinks we ought to use Magnepan. I hope not.

I thoght yours always had the peak :) Seems like you hop from one peak to another

Good for you, and likewise, my system has reached the pinnacle of my ambition.

muralman1

I do not read any forums or magazines anymore. My system has hot the ceiling and there is nothing to improve upon, so i am happy for all striving souals. I do continue to tweaking though but I do not need any amp or speaker or preamp anymore.

The search for a tube amp capable of doing .8 ohm was discussed at length at the Apogee forum. Allen in Europe took up the task to make one. He did.

I like the fact your amps were made in the USA. I know they sound wondrous.

muralman1

What?

gallant_diva

Owner
How about that! Why then all that consternation over Allen's attempt at a 1 ohm capable tube amp do you suppose?

muralman1

"Alas, 1 ohm is beyond the capability of any tube amp. "

Not true. My GT-800 will drive one ohm without any sweat and with full might of 800WPC of pure tube.

gallant_diva

Yes I can see your point, this could be a good time for a second audio system with a more user friendly speaker system that will let you enjoy lower power valve amplifiers.
A nice alternative and a completely different approach to your current amplifier speakers system, as a comparison it might be like a white wine versus a Red wine.

Owner
Thank you Jason for your input. Alas, 1 ohm is beyond the capability of any tube amp. My tubes are in my DAC. The preamp and amp are clear conduits to what my transport and DAC put out. That way, I get the full usefulness of tubes, and non-oversampling.

muralman1

Hi Muralman1
Next you should audition some nice Triode Valve amplifiers, the Triode valve is still the most pure amplification device invented if your speakers allow you to use lower power.
Thanks Jason.

I sent my source duo to my amp and preamp builder, Hung Ho. These are his words:

"I have been listening all morning and YES!!! It is incredible. It is unreal how good the Flatfish and the Audio note sounds. It has the right amount of ambience, air, staging. Bass is beyond description. Very tuneful and meaty with right amount of pitch definition. Vocal is NIRVANA to listen to. Nothing is exaggerated. No wonder you have been screaming how good your system sounds, unfortunately mostly to unbelievers. Oh well, Too bad they missed out big time. Top end is so exxxxxquisite...."

I really hope he decides to go show this system at a show.

muralman1

I just mailed off my source components, the 47 Lab Flatfish, and Audio Note 2.1 Supreme DAC to my amp builder. He has to know how great his system sounds. I will make do in their absence somehow.

I have Itzhak Perlman I got for Christmas. As in real life, in a really highly resolving system, violins sound remarkably different than what average systems relate. The string angle, and pressure subtleties radically change the whole picture drawn by an expert like Itzhak.

My Mother brought down a recording of the Nutcracker she said would mysteriously stop during play on several instances. I noticed several grains of what might have been salt embedded into the CD's protective layer. I cleaned the disc, and slipped it in. The recording was made in Russia.

This should be a reference CD in people's must play collection. The big cymbals lay out a mighty crash on many instances. Other times a harp adds smooth texture. Trumpets blare, strings at full cry, and you can still hear the triangle's tingling.

Oh, and another thing. We played Toy StoryIII Blue Ray today. The thunderous explosions and metallic crashes that lead out the DVD Blue Ray had my wife racing for the volume.

Then, when the scene turned to quiet dialog, she went for the volume again. That movie has dynamics that will stress your speakers. Our couch was jumping up and down.

Reading up on quantum mechanics since it is that science whats torch I am
carrying through audio forums. For Christmas my wife gave me The Amazing
Story of Quantum Mechanics.

Scientists adhering to quantum mechanics gave us the transistor, diode, and
laser. Why do audio engineers feel they can fix imaginary problems by throwing a
lot of math and algorithms at the music?

They can't. All manner of calculus formulated Filters, whether analog or digital,
destroy the continuity of the music signal. My system proves that.

Thank you guys. It took me only 8 years to perfect this sound. Mostly I was lucky
to make the right choices. With these amps every tiny detail matters. For
instance, I put Sonicap Platinum bypass caps across each of the four huge
storage caps. These caps offer huge reserve power, and they also quiet any
ripple distortion. Anyway, the Sonicaps instantly proved to be perfect. Funny,
though, the amp builder has yet to install them on his amps. He has his amps for
sale here. On those amps he has Mundorf bypass caps installed. Those will
probably work better for those with the wrong wires or preamps.
