I'm totally with you on this. I had said in earlier posts before the upgrade came out that I would wait as my experience with many upgrades in different products taught me to be cautious and patient. Plus there never was an indication you could revert to the old firmware if you weren't pleased witht he upgrade.

I am very pleased with the performance of my 990 with the old firmware but would like to try the new one particularly because of reports of improvement in sonic performance. I still can't bring myself to try it though due to the problems a number of people have indicated. I am also a bit disappointed by what seems to be a lack of response from the Outlaw gang in speaking to the problems people have encountered. C'mon guys you produce great products and we all have sung the praises of your customer service don't let us down now.

And I'm willing to listen if someone can convince me to try the upgrade.

I think cappra summed it up well.
There have been several cases where people had an excessively difficult time getting the firmware installed, and I've told Outlaw directly that I'd be strongly in favor of them trying to work with Etronics on a better firmware loader (the one being used by the 990 is the same one used by Sherwood), but there have been a lot of 990's shipped out and a great many of those have been updated painlessly.

I did my upgrade (via USB) with some confidence that it would go okay, but also knowing that the Outlaws would be there if things went down the tubes. Luckily my upgrade went fine, and IMHO the improvements to bass management alone outweigh any risks involved.

lets just hope that this was only the first of the upgrades... and that more will be released in the future.

I think with minor improvements in another upgrade... the 990 would be killer. The one everyone seems to agree on is the display dimmer on the face of the 990. With that and clearning up the problem that some of us are having with being able to use the auto calibrate... and i'd be very happy.

Ok, now it looks like there is a newer update to fix the sub trim problem a few people were having.

When I get my 990 delivered next week, would I have to install both S/W upgrades or just the one released today?

If I read Scott's post correctly, you should only have to install the new one. He indicates that it is otherwise identical to the last release.

NRBQLou is correct - just install the latest and you'll be fine.

I did the upgrade with the USB cable. You have to read the instructions carefully. I took my time to make sure I didn't miss a step. The instructions aren't completely accurate in all cases but it should be easy to work through the small vagaries. My laptop is a very current XP Professional setup.

I agree with the earlier comments that loader should be easier to use and be more reliable. I also think it should be fairly simple to read the old config and restore it afterwards. Being able to store more than one firmware image would be a plus also.

C'mon Mzpro5 let'er rip.

Upgrade the latest firmware last night using USB cable (to fix the sub-trim level bug). One "device restart" but successful second time attempt, I just used main power switch backpanel on/off during the process without actually unplugging the power cord. Since I didn't deleted the first firmware file, I have two version of firmware files in my laptop. BTW, this firmware upgrade did fix the sub-trim level bug for me. Even if there is some potential firmware upgrade problems, I will continue to upgrade the firmware as they become available.

I installed it last night, as well - and updated the firmware update portion of my 990 review today. It went smoothly, and I also verified that the sub trim bug was no longer present.
