Site Title Looks Bold

I’m using a font called Searching For Signal for the title on my website, however, when it’s used for the title it looks like it’s being made bold artificially. The letters and lines are thicker. Any way to fix this?

Here’s how it should look, and how it looks. Both generated using the same .woff font file and web browser:

Here’s my custom CSS:

.site-title a {
    font-family: 'searching_for_signalregular';
    font-size: 90px;
}

Any tips?

Wanted to add, the “How it looks” sample above, I also added spaces (unlike in the example of how it should look). Here is exactly how it looks with no extra spaces:
