I snagged a brand new SE-M5 on eBay a short while back and have been comparing them to my Focals (Elegia and Elear). I drive all of these with my MacBook and my iPhones (new SE and old SE), often via an IFI Hip Dac. The XBass on the Hip Dac is an awesome feature for both the Focals and and the SE-M5. There were only a few occasions where I preferred to switch it off. I chose to use the balanced connection between the Pioneers and the Hip Dac and have not noticed any adverse effects of it.
As many have mentioned, the clamping force of the Focals is definitely greater than that of SE-M5, and in particular the Focals have better isolation and are easier to use in bed
. While the Pioneers are more heavy, I have not experienced this as an issue.
I tried the included pads and the Dekoni Elite solid sheepskins (which are definitely thinner than the stock pads), and in the end settled on the artificial leather stock pad version as best sounding.
To me the Focals are definitely more crisp and clear, but the sound stage is more condensed and the positioning is definitely "in your face". This works well for a lot of my music, but for classical and other instrumental, ambient or acoustic music the SE-M5 offers a superior sound stage and instrument separation, providing a smoother less crispy clarity which I prefer in this setting. In some other cases the SE-M5 gave me an impression that I was "listening through a veil" and this detracted from the sense of the immediacy of the experience.
In the end, I am keeping the Elegia and the SE-M5, and have put up the Elear up for sale on the board.
UPDATE:
So, today I said good bye to my last pair of Focals (not long ago I had three).
When I received HD58X for my BD a few years back, I was impressed. A VW Passat-impressed. When I bought my first Focal, I was suddenly aware how much more (fun) was possible. Like Audi TT-aware. When I purchased the SE-Monitor5's a few weeks ago, I eventually found myself in a Porsche Panamera.
After some experimentation I have settled on velour pads over the fake leather ones, as they seem to give a more neutral response with my IFI Hip Dac (with xBass on). I have also acquired a pair of Dekoni Elite lambskins (designed for Fostex TH900), which fit fine but are thinner and have a slightly smaller inner opening. They do OK, but not as well as stock. Would be nice to find something like a Dekoni Hybrid with close to the Pioneer stock dimensions, but I do not think they exist.
Has anyone tried the ZMF pads? There are some that seem like they may be worth a shot.
Also, I have not seen this mentioned, but SE-M5 are angled in such a way that the cups (even without the pads), and hence the drivers, are further apart in the front than in the back. This is the opposite of Focal's geometry, for example. So the sound in SE-M5's seems to be directed past the opening of the ear canal, rather than into the opening. This may be part of the secret of the wide staging and the airy feel of the SE-M5's.
