Someone who clearly doesn't economics (I have a Masters in Applied Economics) or what actually the Bank of England's calculator compares. It simply compounds the annual average CPI. It doesn't take into account the relative purchasing power of money, nor the cost of production, distribution, marketing etc; nor retail costs for dealers, which have risen hugely in recent years (largely rent increases, and Business Rates) at the expense of margin - staple retailers' average margin has nearly halved. It is not at all a fair way to compare pricing of products over time using a CPI compound calculation. However, having spent the past couple of days in Munich (yesterday attending an industry only day), these Mission products look to be one of the stays of the show (they were not playable), together with other British (at least erstwhile British) products Arcam's SA35 and SA45, and the extraordinary (and very much British) Chord Suzi pre and power amp.
