Initially, I expected to describe it in familiar audiophile terms—warm, analytical, forward, or relaxed. Yet those descriptions never seemed to fit. The A1000’s personality is not expressed through tonal coloration, but through the way it preserves the music itself. Its defining qualities are exceptional control over the loudspeaker, convincing dynamic fidelity, rhythmic precision, and an ability to preserve the individuality of instruments without drawing attention to the amplifier.

Perhaps the most revealing aspect of this evaluation was hearing the A1000 with two loudspeakers that approach music quite differently. The TAD ME1TX and Triangle Magellan Quatuor each retained their own distinct presentation, yet the amplifier’s underlying character remained unmistakable. Rather than imposing a particular sonic signature, the A1000 consistently allowed each loudspeaker to express its strengths while maintaining the musical relationships that make a performance feel believable.

At $32,995, the TAD A1000 occupies the upper tier of integrated amplifiers, where expectations are understandably high. Buyers in this category are not simply purchasing power or features; they are investing in an instrument capable of revealing the full potential of a carefully assembled music system. The A1000 meets those expectations through thoughtful engineering and a level of musical refinement that becomes increasingly apparent with long-term listening.

Using a plain ol’ ‘Red Book’ CD, and satisfying my need to hear mono as well as stereo, the title track from The Door Is Still Open by ’50s R&B group The Cardinals [Collectibles COL-CD-9977] provides the listener with not one but two peerless performances. The first is the exceptional voice of Ernie Warren – a god among doo-wop singers – while the second is the absolutely remarkable saxophone solo from jazz legend Johnny Griffin. You know the drill: the sax seemed to leap from the speakers, while the detail was borderline clinical.

For a 70-year-old recording, the sound quality is almost embarrassing. Hearing it through a no-holds-barred amplifier of such pellucidity, even if from the CD rather than the rare, original 45rpm single, should be mandatory for those who deem anything non-digital (in origin) as prehistoric. Through the I-188, the playback was as vivid as I have heard it, and this song is played to death in my listening diet.

Cashing in

Still, I needed a dose of another mono gem and it was the ‘redneck’ bass on Johnny Cash’s Hot And Blue Guitar [Intervention IT-039] that captured my attention with its solid central image, and no ‘mono’ button to push. As for his voice, the textures were enough to make even a stereo-only enthusiast nod in admiration.

I first discovered this LP in the 1990s, when many people were dumping their vinyl for CDs. That was when I found the EMI pressing of this symphony in nearly perfect condition. It was recorded in 1969 and conducted by Sir Adrian Boult, who was present at its premiere. I’ve heard other versions, but this remains my favorite.

Besides sounding very modern for a popular symphony, I’m a sucker for a symphony that contains either a choir or a pipe organ. This symphony has both. The choir appears in both the second and the final movements, and the organ appears in the third movement. Plus, many might be surprised. Many of Vaughan Williams’ works are not sedate snooze-fests, especially this symphony, and especially not the third movement that morphs into the fourth, the second side of the EMI vinyl.

Thanks to the Element 116MX’s enveloping soundstage, I felt as if I could see into the multi-layered, detailed sound and point to the different instruments and sections of the ensemble. This was true even during the explosive third and fourth movements that make up the climactic portion of the symphony. This section describes the adversaries that Scott encountered, which led to Scott’s demise.

Although no home audio system can replicate the sound of a large orchestra and hall, for example, the 50-foot proscenium of the concert hall stage, the Merrill Element 116MX monoblocks placed me in the 10th row of Kingsway Hall in London, where they created a vivid sonic picture of the orchestra, the choir, and the pipe organ.

Above all, Merrill Element 116MX’s midrange was extremely transparent. The upper strings sounded plush and inviting, as the London Philharmonic in the 1960s was a talented group of musicians, including the masterfully sounding string section. The Element 116MX monoblocks enveloped me in a luxurious string sound, revealed the musicians’ talent, and drew me further into the music.

Chances are a committed audiophile would own a copy of Nils Lofgren’s SACD Acoustic Live, and so let’s spin it up. Immediately there is a dimensional expansion of the sound scape. The scale of stereo imaging within the performance space, including those in front of the stage, are clear to hear. There are great aural hints of 3D space. Space is what you should expect, and that’s what would be a wonderful characteristic of this vacuum tube powered soundscape. Razor edged transient attack is what you might hear with a solid-state setup, yet Rogue Audio’s Cronus Magnum III integrated tube amplifier with phono stage reveals something far more satisfying. The sound is full of natural resonant harmonic overtones both odd and even. More than that, those overtones decay into silence much more gradually. My favorite Harry Pearson phrase is “Continuousness”, and here it fits nicely.

It’s not at all like early digital delineation. That’s when sound levels subside and they are eliminated as a least significant bit. What I have tried to convey is part of what some have called, “Tonal Body” but I would rather call this simply, the Gestalt! That’s when every part blends together and forms a clear coherent concept. There is another significant tonal characteristic of the Magnum III. On a very good recording It puts spaces around and between parts of the performance. It’s subtle, but it’s like a renaissance masters painting in that the main subje

I also must stress that most of the time when listening to this album, I was luxuriating in the sensation of being enveloped by the music on Led Zeppelin II, a recording that I must have heard a thousand times previous to that day. Despite this, before the D’Agostino S350 was in my system, I don’t remember ever having the experience of whipping my head around because I thought I heard something entering my listening room from its far corner. Of course, I’d quickly realize this was a tambourine or other percussion instrument entering the perimeter of the huge soundstage.

The frequency extremes the Dan D’Agostino Master Audio Systems S350 reproduced were extraordinary; never before have I heard a treble sound so extended yet so natural sounding. I’ve had experience with tube amps that had a seductive treble, one that sounded as if it possessed the gestalt of the real thing. Still, the S350 came close to doing this, but at the same time, no amplifier I’ve previously auditioned gave me the impression that I was hearing as close to what was exactly on the signal feeding it. Transparency is the name of the game, and the D’Agostino Progression S350 sound quality possessed what I would call, without exaggerating, the epitome of transparency.

After the D’Agostino S350 was in my system for a while, I never became accustomed to its supernatural sound. Never before have I had a component in my system that made each musical selections, regardless of how many times I’ve heard it before, sound as if I’ve never really heard it. I could use this amplifier to demonstrate every audiophile characteristic that one would desire, frequency extension, transient response, micro and macro dynamics, soundstage, imaging, etc.

In my review of the Mk2, I suggested that Heaven 11 upgrade the RCA input jacks, but it appears for the sake of affordability they are unchanged. The company might have to retool the chassis for such a change, so I can see why they have not done so. Still, I hope that in the future with new designs such an improvement is employed. Does that issue put me off from using the Mk2 or Mk3? Absolutely not! I have had other components with similar RCA jacks. The firmness of the connection is not confidence inspiring, but it never seems to affect the operation. Thankfully, the company is putting the money into serious speaker posts, and the ones used in the Mk2 and Mk3 are exemplary! The heavy posts inspire confidence when heavier cords with spades are cinched down. Far better the speaker posts are strong than the other way around.

As it appears a similar chassis was used for the Mk3, there is still quite close spacing of the output posts, and larger spades are closely anchored. Thus, I continue my precautionary practice of slipping a piece of leather (any non-conducting material will do) between the posts and spades to ensure that if one is loosened it does not contact the other. We know what would happen then, and I take no chances with a class D amp’s output channels shorting. The spades have never come loose previously; the posts are very good. But I am not about to chance it. It may seem odd, then, that I go about system building by splitting digital signals out from sources and horizontally wiring pairs of integrated amplifiers to speakers! While these are odd methods, I have not found them to pose serious risk to components. If they did, I wouldn’t use such methods. As usual, such activities are “do at your own risk”.
