All do respect to Todd W White, rebuilding a factory set of 25-30 year old M19 crossovers with new components would be a noticable improvement indeed.
I think the price may reflect the time it takes to measure & match the values of the components before assembly, as components, regardless of the noted values marked on them, sometimes are not consistant, also burn in is a factor also.

I would get my tech, who is quite brilliant to say the least, rebuild mine, I would save some money, but more so because he does work for me for a good price.
I don't think Iconic is too out of reach for some & I don't think they are way over priced if they take the time to do the mod correctly.
But to some it may seem rather too expensive.
