Resale prices over the long run are most likely the only reliable metric to bank on when it comes to determining value.Mapman,
I understand your point but I look at it differently. I guess it depends if you are going to keep stuff or resell stuff but if you plan to keep things for awhile, another measure of value could be considered the enjoyment something brings to the buyer/user.
I just finished auditioning two very good monoblock amplifiers in my system with the intent to keep one pair or the other. One was designed and manufactured by a highly-regarded designer whose products command universally high resale prices. The other was designed and manufactured by another well-regarded designer that mostly flies below the mainstream radar and whose products do not command anywhere near the resale prices (as a percentage of the new price) as the first designer. I liked the "below the radar" amplifier better in my system and will keep that amplifier and sell the other. In this case, the amplifier I enjoyed the most and kept provides the higher value to me.
Geoff,
The only opinion that matters is the person's who is selling the thing.Replace the word "selling" with "buying"
