Y'all are all going about this the wrong way. Cost is no longer an objective measure of entry level or Low-Fi, Mid-Fi, true Hi-Fi or high end due to the ability to buy things at great discounts. Therefore:
Entry Level -- sounds decent at normal volumes, some loss of highs and lows at loud volume, includes integrated components that are very inexpensive. Movies and pop music sounds good.
Mid-Fi, investor/researcher-type audio hobbyist -- components and speakers that play loudly and cleanly to a point where you can hear any music, free of distortion, in any room of your home... while vacuuming.
Pinnacle Hi-Fi -- similar to previous, can hear any music clearly, cleanly, free of distortion with the windows up and you're mowing your yard with a Honda push mower 🙂
