I don't think an inflation calculator answers the question of what a Luxman PD444 would cost today. Circa 1974 when that turntable was designed, a substantial manufacturing infrastructure and technical coterie existed in Japan for making direct drive turntables. And the market was larger, supporting higher volumes and better marketing efficiency. Those assets are sharply truncated now. For a new company to research, design and manufacture a similar product in low volumes would, I expect, require a selling price well above what inflation suggests. By inflation alone, a PD444 available for $795 in 1978 should come to market for just under $3,000 today. The VPI Classic at $2500 with tonearm gives some hope that might be a supportable assumption. The fact that a simple Pro-ject Xtension (belt drive but mag-lev load-reduced platter and solid plinth) costs over $5,000 without arm and with a commodity motor, or that a Brinkmann Oasis DD costs over $8,000 without tonearm, suggest an inflation-calculated cost won't cover it, given tiny market volume, contemporary manufacturing costs, and modern channel inefficiency in high-end audio.
