Lovely review. Glad to see the face behind these awesome videos.

Fitting all of those analogue goodness in that form factor is superbly impressive. I would love to have this in my studio

Great review Cameron. As a fellow owner I share your enthusiasm for the product. It just takes music to another level. Whilst there are features I don’t use, this targets a wide audience between professional and enthusiasts with something that will tick a specific box for a particular user. Personally I love the +15db for my phono preamp. I also love the stereo base control, it tends to live one notch to the right to just widen things but I’ll switch one notch to the left for older jazz recordings that are hard panned left and right. The one very minor quirk for me is when you switch it on, I’d like channel A to also switch on.

Quite simply, this is the best review I’ve ever seen of ANY amp. Smashed it out the park Cameron. I’ve never heard the MySphere 3.2 sound better.

Thanks for a really wide ranging review. I ordered on of the 2024 production units from your company, so let’s hope they ship on time! (For use with Abyss Diana TC to start).

I tried these recently with Dca stealth alongside with Shangri Senior, Sennheiser HE1 and Oor + hypsos with many high end headphones. The combo of Hm1 + stealth was the absolute best smoothest most enjoyable experience i had that couldn't be explained. Even smoother and better thank tubes yet being detailed, it made me insane

Had the same experience. HM1 + Stealth are close to a perfect match. DCA Stealth never sounded this good, no matter what other amp was used. Detailed, very involving and just pure enjoyment. One and only con for me is the price tag.

Great review, now I have something new to dream about.

How is it with SR1a and CA1a? Even if they are more current based headphones I imagine both resistor and transformer interfaces are not in the sweetspot of what the HM1 delivers the best. Am I right? Thx for the review btw but I will stick to my Purifi amp.

Have you guys tried Heada(mame) closed or open-back? How do they compare to HD600? What about the Ploopy headphones?

that smart crossfeed alone seems like a good reason to buy this, but it’s also easy to emulate cheaply in DACS, for a more realistic price

An $8000 headphone amp will be amazing if you get it custom built, you know the builder, you understand the design and you get a complete breakdown of the parts used. For an $8000 headphone amp from an off the shelf manufacturer you'll be mainly paying for their marketing expenses. For example, open up a higher end Woo Audio and check out the transformers they are using.

I'm waiting for someone to make a cheaper version with all the same features.

It's ironic that you used tracks from Aphex Twin's SAW, given how poor those recordings are (at least on paper). That album has a ton of clipping.. Not what I would pick as reference material. Certainly Richard D James did not use Zahl's gear when he recorded SAW... pretty sure he was like 17 and used a cheap multitrack tape cassette machine. And the Richard D James album was almost certainly all done on a laptop with samples

Fuck me, what a thing of beauty. Only if rich I was

Having heard this I really wish Zahl would release a version that got rid of the A/B, the EQ, The L/R pan. You could then pick if you wanted the servo or non servo version. It would sound the same but be 'affordable'. The extra features are unnecessary. The company would make more profit from this version due to the sheer number of units shifted.

@@enjoshi-godrez8775 Well performance isn't all that complex regarding cameras. There is resolutions like 2k, 4k , 8k becoming more available with time, 4k Red camera in 2007 is an example perhaps. And then the performance of the lens is important probably (i.e. the range / zoom). I know next to nothing about cameras, this is just my first thoughts. My point is that performance is easily quantifiable. Sound might also be quantifiable and not subjective in terms of performance, but it is generally more difficult I think to quantify the performance of sound (or this device in the review) for the average person compared to something like a camera. Understanding frequency response measurements is more difficult than quantifying resolution. Now a camera expert will probably reply and say that resolution has nothing to do with it, everything is fps, color accuracy or maybe even some subjective parameter that belongs to the arts. In that case then I guess I'm wrong.

Am still trying to understand way do people keep trying to find headphones amplifiers (which are sounding linear) when they never really tried real amplifiers I know how this amplifier sounds like without even touching it. Linear and over expensive in excess. Is probably the feedback less version of Ferrum OOR and other similar. Everyone who spends that much money in headphones and amps should know that linear amplifiers sound's life less. A good sounding amplifier will give you an enachement sound (colorised) not linear. Full stop I use Yamaha A-S 501 (speaker output) with my Final D8000 Pro. This combo simply killed other amplifiers like Burson and Feliks Audio.

This is sadly true. Im using a benchmark amp to power susvaras, which does a better job than any amp costing 4 times more than it from what I heard at audio shows. The catch is they are very dangerous to use with dynamic headphones because their voice coils will melt due to farad capacitance attenuated if pushed hard enough. Thats why they all have to have step down relays on the output stage, which reduces the available capacitance, which is the exact opposite thing you want for a planar. Any modern good speaker amp has noise levels low enough that they work fine as headphone amps. I wish more people would realise a headphone amps should really only be used for dynamic headphones.

You should have let one of your Headphoneshow colleagues review this one. Paying USD 7-8k yourself unfortunately tends to distort objectivity.

8:55 To separate the audio to mid/side is NOT much more clever than a crossfeed. A crossfeed has more things going on, and there are different solutions and takes on a crossfeed circuit. 9:14 "Then it applies some crossfeed..." Not true, at least according to the manufacturer. This knob only adjust the volume level of the side information, leaving the mid information constant. Usually when you raise the side volume you get the feeling of the music sounding bigger and wider. But at the same time the relative volume for the mid gets lower in comparison. So stuff that are mixed in the middle (usually vocals, bass, kick drum) get pushed back in the mix. I don't mind having the option to control the mid/side, but there is absolutely nothing clever about it.

One would think that if there was anything more going on it would be mentioned in the manual or on the product page. With a designed test track it would be somewhat easy to check if there's more than just a volume shift for the side signal. "The stereo signal is converted into a mid signal (in simple terms, what L and R have in common) and a side signal (in simple terms, what distinguishes L and R). Summing mid and side signals in a 1:1 ratio will result in the original stereo signal. However, if you change the ratio between mid and side before summing them, you change the stereo base width. In our circuit, we leave the mid signal as it is. We only adjust the level of the side signal.
