As someone with a 2018 Optima with the Harman Kardon System, I wonder how this Krell System will compare:

I'm really curious, the Harman Kardon system imo is very hard to beat, it sounds good with every sort of music in it. How do you guys think the the Krell System will hold up against the HK system.

It will be fun to compare.
Krell is a high-end audio supplier with prior equipment represented by a "budget" $2500 integrated amp AND a $30,000 Pre-Amp. They go higher in $$ as you desire.
They've got to engineer for a confining area and I can't guess the expertise demands designing for a nice-size listening room (amp-sub-speakers) Vs. a car.
I would trust, though, that they Auditioned for this and Sound as good or better.

That's only for the Korean market. That will not come to the US or any place outside of Korea. KIA (and Hyundai) have launched several vehicles with high end audio systems in Korea that we don't get here. The Cadenza and Niro was launched with the Krell audio system, if you saw a Niro before the US launch at dealerships, it had the Krell Audio system in it. The Stinger launched with the Lexicon system and the K3/Forte that recently was launched in Korea has Krell audio system. The 2019 Santa Fe which launched in the last 2 weeks has the Krell system in it as well.

Samsung bought the rights to the HK Group for car audio systems, Krell and Lexicon are a part of that group. With sales of their domestic brand shrinking, I'm sure they are doing what they can to up their game in the home market.
