I appreciate your thinking, but everything tech oriented quickly depreciates and is replaced by even better yet, less expensive items. Those on the bleeding edge typically pay the most.
I buy considering only whether the item is worth the asking price to me at the time of the purchase. If the yuck/buck ratio is good, I buy. It matters not a whit to me what others are doing, what the price may be in two months, what resale may be at some point at time, etc. If I am thinking of resale value at the time I am buying, the product is insufficiently enticing to bother to purchasing it.
It’s a toy, not an investment. The whole point of a hobby is to waste time and money. Audio adroitly fulfills both.
The alternate, much more sensible, approach is to buy last year’s technology in audio, computers, televisions, etc. The prices have dropped and stabilized, the used market is active, the bang/buck ratio is often vastly better. You can easily buy items which will provide years of enjoyment at lesser cost and will make fewer mistakes.
Then again I like risk. YMMV
