I think there is a very blurry line between non-chemical addiction and just liking something very much. Say a person spends thousands on audiophile equipment where the layman couldn’t hear the difference, and often even a double blind of audiophiles can’t, is that spending an addiction? Or do they just enjoy chasing that dragon?

Isn't addiction diagnosis usually about "does this negatively impact your life and relationships"? Basically on the level of "would you get into risky debt or skip on necessities for yourself or family by buying more equipment? "

Yes. This is more or less standard criteria for diagnosing mental disorders.

A. Persistent and recurrent problematic gambling behavior leading to clinically significant impairment or distress, as indicated by the individual exhibiting four (or more) of the following in a 12-month period:

1. Needs to gamble with increasing amounts of money in order to achieve the desired excitement.

2. Is restless or irritable when attempting to cut down or stop gambling.

3. Has made repeated unsuccessful efforts to control, cut back, or stop gambling.

4. Is often preoccupied with gambling (e.g., having persistent thoughts of reliving past gambling experiences, handicapping or planning the next venture, thinking of ways to get money with which to gamble).

5. Often gambles when feeling distressed (e.g., helpless, guilty, anxious, depressed).

6. After losing money gambling, often returns another day to get even (“chasing” one’s losses).

7. Lies to conceal the extent of involvement with gambling.

8. Has jeopardized or lost a significant relationship, job, or educational or career opportunity because of gambling.

9. Relies on others to provide money to relieve desperate financial situations caused by gambling.
