Completely off topic, but this is one of the reasons I don't support any altcoin at all. The only coin worth supporting is one with long-term viability. Mining a coin you expect to die and be overtaken by another is working for short-term profit and in that scenario, when you profit someone is left holding the bag.

Anyway.

If I built a miner better than what Avalon themselves could produce, it's only because I have a different definition of "better" than they're operating with - a different set of priorities. Based on everything from S5 to Avalon6, it looks like the big manufacturers are now prioritizing a minimal parts count and maximizing efficiency. That makes sense, to a certain extent. However, when you run your ASICs at the top end of their efficiency curve you leave a lot of room for improvement (at the expense of more ASICs per hashrate; see S2 1J/GH 1.57GH/ASIC vs S1 2J/GH 2.8GH/ASIC with the same chip). If a miner had a stock setpoint of the chips' top-end capability but allowed for adjusting the clock and voltage, the efficiency could be improved by 30-50% (depends heavily on the chip of course) at a cost of hashrate. But if the miner is priced to break even at top clock, after that any extension of its viable life because of undervolting means more profit. As recently noted in another thread, the year-and-a-half-old SP20 is still viable for some consumers because its adjustable efficiency range is from about 1J/GH down to something like 0.45J/GH, which extended its life substantially and kept it viable through the next two generations of competitor hardware.

In the Avalon4/SP20/S5 generation of gear, I didn't have available funds to buy miners but of those three the only one I actively wanted was the Avalon4. Because it was quiet and allowed for voltage adjustment. Both of those attributes are now considered unneccessary features but if you took a poll of users here you'd likely see an overwhelming response in favor of machines that run quietly and have adjustable voltage. If you want respect from the community, the way to do it is not to ignore them, but to facilitate getting them what they want and doing so graciously. When I got chips from Bitmain there was quite a bit of positive PR in the community for them being willing to make that deal. When Bitfury announced they'd be selling their new chips to third parties, that was the talk for the next few months; when in the previous generation Bitfury kept them all to themselves that was grumbled at for most of a year. Just saying, whether you want money, respect or both, supporting the development of a miner within the community and geared toward the small miners would have an incredible return compared to the amount of effort required.
