Thanks, Mike. Initial show reports mentioned that the S1 would be priced at up to S$10,000, so the indicative pricing is incredible . . . even if I have been informed by someone who has heard the S1 say that there is "stunning" improvement over the A1 on PCM.
As Elberoth had mentioned, the BOM could not have increased by that much (unless further details of the parts improvements are released down the road). It was reported by someone in HK that each Sabre ES9018 costs about US$50, so about US$200 per S1. Its not clear how much more this costs than the Wolfson chips in the A1. There have been reports of other improvements, clocking system, etc. but unless there are further details, it is hard to understand the price increase.
I have been informed though that the stock S1 power supply is much better than the A1, and Lumin has indicated that this may be ordered separately, as an upgrade to the S1.
On the upgrade path for A1 owners, Li did mention earlier this year that there were plans for an upgrade option later, with the cost being the difference in the retail pricing between the 2 (at that time, the retail pricing of the S1 had not been finalised yet). Whether this is still the plan or whether the upgrade cost will be the same remains to be seen.
If the RRP had been about US$10,000, an upgrade would have been attractive to existing owners, especially since the upgrade of the PSU alone would be about US$800+. I would have been tempted but, at twice an A1, well ...
