After 40 years in this crazy hobby of ours, I have zeroed in on the type of sound I like. I have been going deeper and deeper into the high-efficiency, Single Ended flea power amplifiers rabbit holes. One thing I have learned is that while the contributions of the individual components obviously matter, the goal is to achieve a composite resultant sound at the listening chair that you enjoy or are after. I have explored many of the different component design and system topologies in the home audio reproduction universe and have come to greatly appreciate the sound of Type 45, triode strapped 46, and 183/483 tubes used in the output stage. These have become my favorite output tubes, but I have and have heard great results with other tubes and many different designs.

The hearing Type 45 for the first time on a pair of Bottlehead Paramour 45 built by Will Vincent put me in a world beyond the 300B and 2A3 SET amplifiers and sent me on a deep dive down the 45 rabbit hole. I then got a got a pair of Bottlehead Paramour II 45 monoblock with the iron, capacitor, and shunt-regulated upgrade and my ears and mind became intoxicated with that sound of clarity, intimacy, articulation, texture and musicality that the 45 tube deliver. I asked my friend Sean Casper to build me a pair of his reference 45 monoblocks and they have serve me as a datum to evaluating amplifier of lol kinds and power. Since those early days, I have been fortunate to have had the opportunity to acquire other Type 45 amplifiers that deliver their magic in different flavors and with different strengths and weaknesses.

I’m a firm believer that the best value in our hobby is found with the offerings from hobbyists who share their passion with others by offering their builds or services to those of us with limited time and devoid of the skills necessary to to tackle the DIY builds of these relative simple but deeply complex amplifiers as every little thing counts. I have a passion for challenging myself to assemble different systems that to my ears sound great in the typical homeroom domestic environment without the need for the lunacy or even the aesthetics that the audiophile world now seemingly requires for good sound.

To get to the purpose of this post, the commercial side of the audio world has shown very little to no interest on such low power amplifiers as they require efficient speakers to work and that is against the trend of higher power amplifier, specially now that class D amplifiers have become more widely accepted, and multi-driver speaker systems that are inefficient, have complex crossovers, and demanding impedance curves.

But two brands in the mainstream audio/ audiophile world’s consciousness that have produced commercially available 45 either as catalog products or custom-shop offerings are Audio Note UK and Wavelength Audio. Wavelength Audio blurs the lines between a bonafide commercial brand and a DIY builder as Gordon Rankin personally builds each unit and his custom shop builds are each unique and configured with Gordon or customer selected options at different levels of madness.

Recently I was fortunate enough to acquired the best or highest build configuration of the AudioNote Paladin 45 amplifier, which has now been sadly discontinued and not longer offered, and what I consider Gordon Rankin’s best Wavelength Audio 45 custom shop builds. I was/am really impressed by the sound of these 45 amplifiers, so much so that I wanted to do a direct comparison of their sound in the same identical system, with nothing changed accept the amplifier themselves. Everything was the same, cables, power cord, etc, in every case except the amplifier in use.

These all sounded fantastic to me, so much so that I could not pick a favorite in real time. So I did some audio recordings of the same songs/tracks with each amplifiers to see if a postmortem analysis could yield a clear winner.

What do you think?

I have 11 or 12 Type 45 amplifiers at home at this time so there is another five or six to compare, including the Thomas Mayer 45, Sean Casper 45 monoblocks, Jeff Korneff 45, the Bottlehead Paramour I and II series Monoblocks, Isamu Asano Loftin -White 45, the Tadaatsu Atarashi 45 push-pull monoblock amps, and the mighty James “Jim” Burgess 3-stage 45 amplifiers still to compare but the logistics and floor space required may not allow those comparisons any time soon but I wanted to share my excitement and experience over the past few weeks with the group. Let me know which sounds you find best to you on these audio recordings.

I’m both surprised and intrigued by the lack of participation in this thread. To me this hobby revolves and it’s centered around music and achieving a sound that is both believable and enjoyable. I like talking and writing about the equipment but to me the equipment is solely a means to an end to the music.

Here is a different set of audio recordings of another song track recorded on the same exact system over the last two weekends with the only change each time being the power amplifier:

It's a worthy notion, but unless one is listening to these videos on a system that reproduce the audio at the same level it was produced at, it may be hard to discern differences. Listening on my laptop or phone won'd do them justice. Also, were all these recordings level matched at output? If they aren't, the comparisons are entertainment and nothing more and certainly not anything to make judgments based upon.

I own these amplifiers and they were played on one of. my systems. The same judgment that I passed in my listening room on their sound differences can easily be discerned on these audio recordings. This is not theory but empirical analysis in my case.
 
What is your ranking of them from best to worst?
That takes some of the fun out of this thread, but to me the Radu Tarta “Turbo 45” stood out head and shoulders above the rest, both real-time in the room and on the audio recordings.
 
What did you use for recording microphones and A/D and recorder? I was just at a friend's place last week and he refused to let me shoot a video for my youtube channel, proclaiming that it would not 'represent' the real sound of his system. I somewhat agree, but my videos are just to show off the visuals of a system for the most part. I use an older iPhone for my videos- not exactly reference level for quality :-)

If there is one thing that the guy with Believe In HiFi, Joshua Masongsong, has proven is that the quality and/or cost of your recording equipment will not govern the resultant sound of the audio recordings. He has reference studio Neumann and Telefunken microphones paired with world-class studio grade electronics and the sound of his recordings are not impressive, at least to me.

The Shure SM58 microphone has been the most widely and popularly used microphone for recordings in the history of recorded music. If your system sounds good or if it doesn’t, the audio recordings with your iPhone 17 Pro Max or similar will be able to convey that.

What’s your YouTube channel?

Sorry I don’t have a YouTube channel. I make the audio recordings for myself to compare component and system setups and share a few of my audio recordings, but they are private or unlisted in YouTube and you must have a link to access them. For those wondering why I record my systems, because audio recordings are a much more reliable way to analyze and assess than fleeting aural memory. A comparison like this with five different amplifiers cannot be conducted with any great accuracy or certainty with just fleeting aural memory. This is why audio recordings exist. I have a lot of inside into sound reproduction and home playback system building knowledge to share but a YouTube channel has not been one of my interests. I do this for fun and for myself.
 
You write "I’m both surprised and intrigued by the lack of participation in this thread."

As some of us have pointed out before there’s little point listening to these through the convoluted process involved, or any such demo for that matter. That shouldn’t come as a surprise. If you find it intriguing you can revisit past threads and reread the reasons why, I suppose.
I’m not looking to stir this up at all, just trying to help you see why I for one consider it a waste of my time to participate further.

I completely disagree with you on this. There is a great deal of information that can be derived from these audio recordings. I don’t want to rewrite and re-explain what I have already written and explained more times than I care to count. The entire premise of this hobby is predicated on audio recordings convey information that we can reproduce at home through countless distinct and widely different playback systems in varied acoustical environments; and now you want to tell me that a simple audio recording cannot be trusted to convey sound qualities and attributes? If that was the case then the whole logic behind this hobby falls apart. You can’t have it both ways! Either audio recordings can be trusted to convey sound qualities and information or they cannot. So which one is it?

The truth of the matter is that those that claim that audio recordings of one’s system are of no value are typically those not confident to put the sound of their system out there for others to judge. The audio recordings are what they are, there is nowhere to hide.

I don’t know how to get you to understand the difference between you playing your recording back on your system versus sending it out over the net to be played back on my computer speaks. And Boy Howdy, if those amps show enough of a difference among them to survive that recording process you got some problems...

Then, for the second part above, that reminds me of an old joke about a horse in a bar, laughter, tears, and a bucket of cash...
 
What???!!!

Look it up. Every garage band has started with that microphone and you be surprised how many records have been made with that microphone.

See what many don’t seem to get is that music is art and so is home audio system building, they are like cooking. The cost and quality of the ingredients doesn’t always correlate with the end result. The resultant sound at the listening chair is all that matters, just like the taste of that meal in front of you. It is the end product that makes a difference and that matters the most. You can assemble the most expensive and so called “best” components but if you don’t know or understand diddly squat about the science and technology of sound reproduction then the chances of ending up with a winner are very low.

Isn’t this exactly what streaming from Tidal, Qobuz, Amazon Music, Spotify and other streaming services is?

Oh, please. Sure you can record with a 58. You can also use it as a hammer. Will it do justice to a grand piano or even an acoustic Of course not. Put it on a snare? Not if there’s a 57 around. Or even an AKG D1000E. And lots of garage bands couldn’t afford a 58 - that’s a rich kid’s starter.

I wouldn’t know. I don’t stream.

On the contrary, if the differences in the sound between those five amps did not show up on these audio recordings……then we would all have a real problem.
 
Oh dear. It is if tidal makes their files using a smart-phone video.

These audio recordings are of one of my systems. I can certainly use my Sanken microphones to record my systems and put them thought my Fairman TRC (Tube Recording Channel) then through my Digital Audio Denmark AX24 AD/DA converter, Would that gain the audio recordings credibility? You can see pictures not all these mastering studio equipment inn my pictures of my main listening room. I have also experimented with using studio grade equipment for recording my systems like Joshua Masongsong at Beileve In High Fidelity has and I can tell you it is not worth the hassle. For quick compares my iPhone 17 Pro Max delivers a level where I can discern the sound qualities that I need for my analysis and assessments.
