Current consumption roughly 400mA at 150MHz? No, thank you.

400mA at 3.3V or 1.32 Watts !! Are you kidding me !!

And that's with all of the peripherals running as well !!

And there is more !! 60 bucks for an ICE. Ebay number 350473496337. Check it out

Is this a question?

Again, no. Steph's XMC4500 Relax board with two CPUs on it is under half that price here. As well as much lower power consumption.

the price and power is not an issue at all at 1 watt and you know how it is, there will always be someone who wants a 4-way active crossover

Why would that someone want an XO though that consumes more power, rather than less?

Time to practice with the sole and only member that's curently available, the XMC4500? Time to buy a few XMC4500 Relax Lite Kits from Hitex? XMC4500 Relax Lite Kit

that's like asking what is the price of fish is on mars. The power has no relevance whatsoever unless you are running it from batteries which I don't think is a requirement here. There are plenty here who run dsp crossovers on their PC hardware. What power do you think they consume ? A lot more than a TMS320F28335 !!

The TI dsps are well documented and well supported and have been for decades which is more than I can say for these cortex M4 devices.

I'm not following you. Perhaps explain the steps you used to reach this analogy?

Why not go for the lowest power and lowest price, all other things being equal? Don't just assert, explain why power isn't relevant. In any case even though you don't find it relevant, I most certainly do and it was you pitching the product.

So what? Plenty of people leave windows open with the aircon running.

Relevance? TI will be dead long before ARM gives up the ghost - have you checked the relative corporate performance of the two any time recently? Investing effort in learning TI proprietary hardware isn't a long-term investment at all.

I found a seller on Taobao for 180rmb so I'll go that route for now. However I have something of a back-log of devboards here....
