Axiom Home Page Forums General Discussion The Water Cooler CV's Subterranean Adventure

I upgraded my vision with LASIK. First impressions were that my eyesight was as good as when I was wearing glasses, but a week later, it seems to be better than with glasses. Everything looks so clear, and even the colors are jumping out at me more, which I wasn't expecting. Even my OLED TV looks better than it used to, so I think this counts as a home theater upgrade. I have to say I'm really happy with the results.

I had mine done in 2008. They only promised 20/20 vision, but I ended up with 20/15. My night vision was shot for the first couple of years, but it eventually returned to normal after 4 years.

I was warned that I'd need reading glasses in my mid-40's once my corneas hardened, but I can read just fine in my early 50's. I think it helps having a LCHF diet that prevents eye issues centered around advanced glycation end-products of a modern diet.

What was shot about your night vision? I have a little bit of a halo effect around lights, but it's not terrible. I had a quick appointment with my eye doctor today, and he said my vision is 20/15, too. I told him I keep finding myself looking around and thinking to myself that things have never looked this good.

Everyone has said the same thing to me about reading glasses. So far I'm fine at 44, but I'm sure my days are numbered.

For a while, every point source of light in the dark had a halo: street lights, fairy lights, signal lights, headlights. Night time driving was quite dangerous, as if your eyeglasses were smeared with fingerprint oils at night. It does heal though.

My entire time with eyeglasses, I never managed better than 20/20 vision. It's amazing what modern surgery can do...if you can get past the burning smell of your cornea being cauterized.

Oh no, just found out the front tweeters and mids on both Active LFRs aren't operating. I wonder when they went out. It's both a testament to the speakers that they can still sound so full with just the rear portions working, as well as to my lack of golden ears. It seems like a bizarre coincidence that it's just the tweeters and mids on both. Woofer sections are both working. I'd like to think I would notice if just one side went out at a time, so I'm really not sure what happened. I would still guess it's amp issues as opposed to DSP, but I doubt I'll have the time to troubleshoot until the weekend. I don't look forward to the wait time to get stuff repaired, but at least I can move my M5HPs I'm using as rear surrounds up to the front to get by in the meantime. And I still have an ADA1000 sitting unused until I get a pre-pro or receiver that can do ceiling speakers, so I can do better than the receiver's amplification at least.

I don't think I make enough money to keep staying at Axiom's bleeding edge. When I'm out of warranty and it's going to cost too much to repair them, I may have to switch back to passive speakers with fewer amp channels. They sound so good and look so pretty, but it certainly comes with challenges. I think my last big audio splurge will be the Anthem AVM 70 8K--or whatever I land on--to see how much difference that part of the audio chain makes. I'll ride it as long as possible, and after that I imagine I'll return to more reasonably-price receivers because technology moves too fast.

Damn!

Do you have a meter and know how to use it?

A multimeter? I don't, but I can borrow one from my dad.

Oh, and I don't know how to use it, so I'll take a lesson if you're offering. Otherwise my dad could probably get me through it.

Your dad is a flight of stairs away so he's your best bet. If he incinerates himself, I can help (not him...you).

The safest way for product and humans is to shut the ADAs off, unplug the cables at the speakers and check Ohms at the driver terminals. Mids and tweeters should be 6 to 8 Ohms. It's highly unlikely drivers are the problem.

Then you can play some music and check for AC voltage at the outputs of the DSP. That's low voltage that won't even vaporize a gnat's 'nads.

First thing I'd do though is shut everything down via the rocker switches and see if the problem clears.

I've already done the rocker switches multiple times. I'll let you know what happens with the rest.
