The show is great, I could hear it for hours. The sound is strange, it might be the filters you use + the compression. That is the key really.
Also the hardware, in my laptop the sound is bad, in my mobile the sound is a bit better (that is definitely my end) but platforms like sound cloud and youtube will compress even more what is already compressed. I would check the filters and the output compression. Perhaps upload a larger file with less compression.
Now, the production itself. In the final mix one mic is louder than the other, the music choice is interesting, I understand why you are using music, and I get why that one in particular

You get the idea. I always used music in background, if it was my choice I would use some of the songs available in GT SPort, simply because they are more linear. For instance "I like london in the rain" has too many variations, but this one "Blue Fenix" by Channel U is more lineal. Achieves the effect of "hiding the silence" but does not add too many "peaks" to your wave sound.
We used to interview journalists all over Europe and I remember we expended more time in the post production than in the production itself. One hour show required about 3 hours of post production. When you sit with someone who knows what he is talking about, you just 'let him do the show', that part is actually easy. The hard bit is to find a sound configuration that works in any platform. The less elements in the soundwave, the better, imo. Your sound (as clean as possible), his sound (as clean as possible) and soft-linear background music.
Or maybe is me just being picky
I love the show anyways. Sure you can get half of the Nurburgring finalist to talk about sim racing.
