It appears like you say they registered the domain name in Ontario.  The domain history is listed on whois:

Important Dates
Updated Date: 2016-06-17
Created Date: 2006-06-05
Registration Expiration Date: 2017-06-05

Here is the information I get from Chloe at Inno in her email:

Give that a try and see if that helps.

Also - why is the "Whois" data for their domain name "Private?"  Has it always been this way?  This certainly does not make a company sound more legitimate.

I guess one could pay the $49 to Domaintools and take a look at their domain history....

Might be worth it.

I mean even KNCMiner doesn't hide their domain registration.

Well unfortunately I get:

1.  A either a voicemail message or a fast busy on the international number
2.  No response to my emails
3.  The addresses they list are not complete

The other phone number is just some # in Toronto.

Everything you need is on their website http://innosilicon.com/

If anyone could forward the correct email address / their local phone number / their place of business address -- regarding a visit -- I would appreciate it!

I would be wiling to purchase a unit at 2x to 3x the $1800 price in order to test it now and then I'd gladly purchase additional units after a visit to their facility.  I'll have a lot of free time on my trip to Asia.

If your wanting to buy one of the pre-order miners and pick it up then yes I would assume you would need to place your order today in order to pick one up at their facility.  I don't know why your not getting a response from Inno about your request to visit.  If you would like I can ask them about it.

On the A4, that is correct, no PSU is included and we will need to invest in a PSU with at least 8 PCIE ports and can handle the miner load.  I think several of us are already in that mental process of sorting out the PSU.  I have asked Inno for some more info on what they recommend for the PSU.  The A4 has 3 "modes", and the turbo mode which runs full out looks like it is going to consume about 896 watts roughly at the miner.  However there are 2 slower modes that use less power, and reduce the hash rate.  However I see your point in that why pay for the A4 hashing capability when you just want a smaller version.  They had smaller versions of the A2.  So that is quite possible in the future.  But so far we have not heard anything along those lines yet from Inno.

But this is assuming you wire them money in advance. 

I have emailed them, with no response.  I would like to tour their facility in August.  Also - why won't they deal with a 3rd party escrow?

Finally -- this price is not including the PSU?  If it uses about 1KW then we would need a 1.2KW supply?  So this would add another $200 to $250 if you go for a good one?

It would be great if they could create a "mini" version that uses half the power -- as that is so much easier to deal with.  Perhaps the best route is to go 220 volts.

I don't like units that hover around 1KW.  It just sets you up for trouble.

Neat. Thanks for getting back on this.

On the topic of picking up the miner while visiting China, the answer is yes you can pickup the A4 once they are available at the Inno warehouse in Shenzhen.

For those who have gotten invoices for your orders there was a typo on the invoice that stated the A4 is 260mh.  That is incorrect, it should state 280mh.  Please reach out to Chloe and ask for an updated invoice with the corrected info.

Hi Everyone,

I am back.  Looks like a good discussion here!  I love it!  I agree with Searing on many of his points here.  The Titan's useful life certainly has not only been extended by the community, but improved.  I can only hope the A4 can get that kind of support.

The fact that there isn't a huge difference between the A4 and the Titan should mean the Titan's will get an extension lease on life for some time unless Inno or someone else comes out with a screaming fast miner relatively soon.

But like others here have already mentioned the question about interest in LTC is good.  Clearly as Searing has pointed out LTC can be profitable with an efficient miner.  How long it will remain so is anyones guess.  And there aren't that many Titan's out there so the A4 could change the landscape a little, but it will depend on how many people run out and buy them.  It is a numbers game. 

Others have mentioned there isn't any interest in scrypt or LTC.  Then maybe the A4 does not sell that well.  I guess we will find out soon enough regular availability of the A4 should happen not long after the Batch 1 units ship would be my guess. 

I believe that a small run (to validate the design) has already happened to produce engineering test samples, that's most likely where the evolving hashrate numbers came from.
The initial engineering samples are made from a small lab the FAB operates for just such purposes.
However, when they go for a production run, it may have some tweaks from the initial run. I would think they probably get 100K chips or some such number from a production run in order to get the economy of scale needed to reduce the per-chip price from the FAB. That's just my guess anyhow, not trying to say its fact.

Anyone get an invoice for their pre order yet?

I really hope for those people who pre-ordered 76 units they aren't being used to "validate the design".   Innosilicon has been soliciting investors publicly since last November precisely for that reason.  If they are taking pre-orders to "validate the design", then that's a huge red flag that they are undercapitalized.  If the design isn't successfully validated, then I guess there will be another crop of people happy to spend their money on Batch 2 without recourse and no guarantees. 

Is the hashrate guaranteed (+/- 10%) from Innosilicon?  Are there any policies to return the equipment for failure to perform other than the 45 day warranty (which doesn't include returns from what I've followed in the thread).

I recall from other HW discussions elsewhere that even if they have a design for the A4, they have to commit to a level of production with an established chip-maker and get on their schedule.
These things take time and need to be worked out in advance. They just can't show up at a FAB and request 1000 chips. The run has to be substantial enough to make it cost effective for both the designer and the FAB.
I think the pre-orders are a way to help ensure the cost structure is in place to cover the run or future runs if they had a small initial run to validate the design.

I would imagine the pre-order to mean that they just ramp up the production quantity and would be able to do a known quantity run. This would mean that they have already produced the A4's in a prior run to iron out all the issues (there always are). This would then mean that the A4's are already out there....

But then again, I don't think I've seen the difficulty spike. So maybe my assumptions are wrong....

It is so refreshing to see people actually look at the numbers and current situation -- instead of just going crazy with BUY BUY BUY!

I see these units great if you pay very little for electricity -- but then the A2s are still great if you pay little for electricity.

On a side note -- having a lot of hash power at your immediate disposal (like 2GH) can really create some "interesting" opportunities with different coins -- but that is a whole other subject.

I'm thinking of putting my 30+ A2s back online -- but only to use them strategically with certain coins.  Not to run them 24/7.

I'd gladly buy a proven A4 unit for twice the price right now if I was guaranteed to receive it within a week and there was no risk (by using a credit card or escrow company).

You very well could be right and we could see the equiv of the 2013 to 2014 massive difficulty rise like BTC saw those years. My view is that the A4 is NOT any better then a
325mh 1250watt Titan...or damn close. The odds of finding a 'used' Titan that does the whole 350mh at this point in time almost 2 years later is small..maybe 1 out of 20.
So with innsilicon saying they 'beat' the Titan...well it ain't by much and in 'reality' with only used Titans out there..probably not even that (assuming 325mh at 1250 watts)

BUT......something has or will likely replace the A2's and that likely will be A4's at this point in time. GPU's etc or less then say the A2's 110mh have already gone to doorstop
status me thinks.

So with the Titans getting older (some likely fading) ...the A2's slowly losing ground and being shut off...and the A4's being the only game in town ..new anyway.....it could
just be a 'wash' ..ie back to difficulty of say end of 2015 when A2's were strong and some GPU's were still mining LTC. Thus me thinks is the 'bet' of folk getting A4's. Not
enough incentive for new scrypt miners by others due to price etc..and the fact the A4 is already out there...thus another 2 years of same old same old (i wish)

But really at $4 buck prices I'm not sure we will see any others. If the price were to go say to $5 and above for LTC imho you'd see such an announcement of new equip
that likely would materialize 5 or 6 months from now...from others on top of an A4 ramp up too boot ...thus we could see just 'more of the same' the next 2years because the A4 is only one who has jumped in and there main claim to fame in that time period may just be to replace as I said above 2015 gpus/and A2's etc. The Titans can run with the A4's fine efficiency and miner wise but they are getting older and could start to fade...anyway my view on why folk are getting A4's ..but lots of moving parts in all this

Then again innsilicon is a 'chip maker' they supposedly "don't mine' I suppose they could just flood the whole scrypt miner universe as a result and A4's could be more common
then toasters.....as they swamp the scrypt landscape

but from my view....kinda ...looks with how close this all is to a Titan ...just more of the same....but again innsilicon could flood the market with scrypt miners I suppose

but yeah lots of moving parts.the key in all this is WHAT price point on LTC would it take say for others to jump in with their version of a scrypt miner? 5/7/10 bucks?

anyway all very daunting to keep track of all the balls in the air on this kinda stuff

A lot of unknowns are happening. I think that if there was a chance for a huge profit on LTC machines, someone else in China would have made a machine.  Just saying that a company such as Innosilicon has to preorder this sucker. Why? If it is such a great LTC miner with huge potential and the Chinese have zero electric cost, then it should be a no brainer. Yet again this preorder BS has me thinking. I am probably wrong but something doesn't seem right.
