??? Where Does "High End" Start ???

A better questions would be, how much one is willing to shed for Hifidality Audio reproduction? Hifidelity audio, or Hi-Fi, refers to the high-quality reproduction of sound. It aims to recreate the original recording as accurately as possible, with minimal noise and distortion, and a faithful representation of the full range of audible frequencies. It’s a term popular with audiophiles and home audio enthusiasts who appreciate a detailed, immersive, and emotionally engaging listening experience

Based on your listening habits, you can decided the price point where you are satisfied with the music you are hearing. Does it really matter how much you spend to get that sound quality? I don't think so. All other categories from entry level to low-fi, mid-fi, etc., are irrelevant. Amount one can spend on this hobby will depend on many factors. What matters is whether your audio system reproduce Hi-Fi music to your satisfaction at whatever price point you are comfortable.

If Audio Nirvana is 100% then I’d say high end gets you to 94-100, mid is between 85-93 and entry level is below 85.  

@devinplombier Let me know when you throw the NAD in the trash so I can dig it out. I’d own it with pride. Most American can not afford a NAD. I’d be grateful to own one.

Can not figure out if your statement is a joke or just a bizarre comment. 

I think what level a component is can also be determined by brand. When we see VAC, Boulder , Rockport , CH Precision ,ARC  etc. don’t we automatically think high end? 

No one should care about such a label. It’s the province of gatekeepers and the insecure.  Play what you like, can afford and makes you happy. Enjoy music.
