Oppo HA-1 Impressions Thread

[x RELIC x]

i usually have my LCD3s in balanced around 1-3 oclock on high gain.

if you hear "crackling/static" in your ear (not the headphones) that means you are listening too loud right?

That sounds like it might be a bit loud for your hearing using balanced, which is four times more powerful than single ended. 110 Ohm and 102 db/1mW isn't too hard for the HA-1 to drive at all. The optimal driving power for the LCD-3 is 1-4 W so I don't think the amp is clipping or the headphones are being driven too hard (HA-1 max output in balanced is 3W@32 Ohm).

oh its DEFN my ears, not the amp  - it only happened a couple of times - it felt like water was going in my ears and i could hear it...but yes i think it was my ears, not the amp or the cans.

Your not long for this hifi world if you keep listening at those levels.  Good luck.

Yeah ill wind it down a bit. Doesn't happen with speakers, only with headphones so I'll just ease it up with them.

I get to 2 and if I'm brave 3 when listening to my Mcintosh cans. They are rated at 200.

You are in a different league buddy

Hope you found the right groove with the rig buddy. Be careful and enjoy the ride!

Hello, Everyone The loudness problem is alarming!! Does anyone if i can use the decibel meter from radioshack and put it in between my cans to measure the real volume???? Also what decibel level is safe for long hours of listening. Thank you all in advance.

Here's a useful chart. http://www.gcaudio.com/resources/howtos/loudness.html
Take a look at the OSHA and NIOSH Daily Permissible Noise Level Exposure. Generally, for long listening sessions, it's safer to be below 85db.

There are some sound meter apps for android and probably also apple.  I have one for my android phone that I use to tweak my home theater set up.

What do you mean?

Thank you so much for the illuminating chart LMF22!!! I just popped in the battery in the Decibel meter and at volume 50 on the asus xonar u7 with the hd700s i measured about 70 decibels!!! I placed the mic inside the ear cup because thats where my eardrums would be located. I have to be very careful with rock and roll. Classical is a little safer. I think the reason people destroy their eardrums is because they trust the volume level on their devices. I guess hearing loss would be to put it in a poetic fashion "like a slow closing door that can never be opened again" and the only way you know is that you need to keep raising volume to enjoy. We will see when we all hit 100 years old on this site, what new ear drums we can purchase!!! lol

It would be good if every audio component maker that produces equipment with a volume control provided a hearing chart at least. An app or included db meter in the box (they aren't that expensive) would be icing on the cake. That way they can have the retired wealthy still appreciate their gear and spend more money.

Lol...referring to those awesome Macs that you have. I assume its difficult to resist cranking up the volume to 3 o'clock

I have been cranking them.
 
On the topic of how laud we listen im curious to know how laud you would have to drive headphones before you would do damage to the phones. Is it possible to damage headphones at listening levels we would actually listen to, or would they be so laud at that point you couldnt stand to listen? Would any of the high quality headphones be damages if the Oppo was at 100% power output, or could they likey handle that?
