Thank you for the review.

As a Xenns Up owner I'm not that intrigued haha. I also think that the sub bass is already pretty good. The only set I owned that beat it was the Monarch Mk3.

Yea I have heard good things about the Monarch MK3, also I’m interested in symphoniumaudio’s titan as someone told me it has more bass than the UP and the same level of technicalities. Definitely gonna demo the MK3 & titan this coming CanJam London.

No, nothing like that.

I posted soem details in this thread:

What is the fuse characteristics for the Swiss Box? 1A, slow blow, Copper 5x20 mm?

Enjoy your writeup, thanks for sharing.

Haven't though of dust caps and 90-degree RCA adapters, nice ideas (my custom power cables are 90-degree terminated which works great here).

I have the same tube combo as I shared in the product thread, with the exception of gain tube where I use RCA 6BQ7A Black Plates "O" getter (1957). It workds great with the output tubes and rectifier you have. I may need to try again the JAN6922 (have a Sylvania 1970s era one somewhere in my inventory).

thanks again!

Great review! Concerning input and outputs: I am happy they are on the same side. Otherwise it would not be portable. I wouldn’t be able to put it in my pocket together with my iPhone. On the desk, well, maybe, but as CMA18P is a „portable“ device, as says its name, I think they did the right design choice here.

Yes, it's an issue for me while using it with my desktop PC, but not with phones or when in BT mode (more of a personal gripe than a con really). I use it mostly for BT, lol, because the implementation is so good.

Very detailed review! Thanks for sharing!
I'm using it with an iPhone, so all the connections on the same side are perfect. The dimension is great, too, because it fits perfectly on the back of the cell. Hopefully, future versions can be thinner. Anyway, I have no complaints at all.

To your ears, is mid-blass bleed related to time (transient speed) or frequency (separation of mids and bass frequencies)? Some mean the latter, and in that case, the P1 Max II is definitely a mid-bass bleeding set.

Hi @MidnightSun , I would say it is probably both factors combined.

I find planar drivers (like in the P1 Max II) are usually more speedy than DD bass for example, and we also have to factor in the rest of the frequency response (not just the bass in isolation, but how it relates to the mids and treble). One also has to factor in hearing health, volume played at (Fletcher Munson curve), ear anatomy with eartips etc.

Nothing beats putting the IEM in the ears to have a listen, rather than just looking at a graph.

Thanks for the answer!

Clear, easy to understand and to-the-point. Good job! Looking forward for more reviews from you.

@NebelHexen,
Ha, thank-you. It is maybe a confusing, wacky and long visit into typical audiophile ideas. It is rambling and long, and I don’t exactly even know what it is? Lol But I’m glad somebody liked it. Cheers!

It is well done and rooted in the scientific method.
