Masimo gives up.

Mahler123 I think Masimo have no idea about audio business? Even Marantz they did not have good technical service after warranty.

Think about all the mis-matches:

Singer Sewing Machine bought KLH and trashed it; Teledyne bought Acoustic Research and trashed it; Tyco bought Dynaco and trashed; Emerson Electric bought Fisher Radio and then sold it to Sanyo who trashed Fisher's reputation. H. H. Scott was sold to its European distributors and then to Emerson Radio (different from Emerson Electric) and made crap lo-fi equipment until it disappeared. 

Moral: Big business and the hi-fi business do not mix. We've lost a lot of great companies thanks to companies such as Masimo (and, so far as I'm concerned, Samsung buying Harman.).

It's not tariffs a company buys another with no idea what they are doing and they were bleeding money. This happens when they just want to make more and put in cheaper parts ask ARC

Well, it's not that Masimo gave up. The board never wanted to make the purchase in the first place, but the founder and CEO did it anyway. Then the board began steps to force him out, and immediately put things in motion to get rid of said purchase.

The above is correct.  However the Corporation, whatever their motives, did buy the audio companies and then discard them, and corporations are an entity independent of the individuals who work for them
