I’d like to extend a special thanks to Piotr and his team at PMG Audio for sending us a review sample of Apx ME with no expectations other than a fair and timely review. We are not affiliated with PMG Audio in any way, but have always enjoyed a positive and productive relationship with Piotr, and appreciate his immense contribution to the portable audio community.
Welcome back to the second installment of what might well be the longest IEM review I’ve ever written. If you haven’t already, I’d strongly recommend reading Part One before diving into this section – it’ll give you the context and foundation you’ll need to make sense of what follows.
Now, in Part Two, I’m getting into the nitty–gritty. Over the following pages, I’ll be comparing Apx ME against four other flagship IEMs that represent different approaches to high–end sound. These aren’t random selections – they’re four IEMs that, along with Apx ME, currently make up my top five, each bringing something different to the table.
The comparisons will be detailed, with specific track notes that I encourage you to try yourself. I’ll also be exploring how Apx ME responds to cable swapping, tip rolling, and different sources – from humble dongles to desktop rigs – to help paint a complete picture of what this IEM can do.
Before we begin, a quick disclaimer: everything here is filtered through my preferences, my music library, and my ears. What I hear as smooth and refined, you might find too restrained. What I describe as perfectly balanced might strike you as bass–heavy. That’s the nature of this hobby, and it’s why demoing is essential.
Think of this review as a comprehensive guide rather than gospel truth. Use it as a starting point for your own explorations, knowing that your mileage may very well vary. Right, let’s crack on.
