Oppo PM-1 Planar Magnetic Headphone Impressions Thread - Page 113

I'll agree with Frank on the burn it. They do need to be cooked for about 50-75 hours. The bass is where I'm hearing the biggest difference after burn in.

Statements like this really confuse people new to the scene. Maybe you're ears needed 50 hours to get acquainted to the sound but, from memory, no one in the beta, including me, experienced burn-in with either the Beta 1 or Beta 2 and I sure as heck disagree 100% that there is any burn-in with the retail version.

 

It's like one person makes this statement and everyone suddenly needs to search for minute differences every hour.

I agree with Frank and MattTCG. I left mine running constantly for a week and IMO they got better overtime. Last night I was listening to them out of my new AK240 with the DHC Monocle Hybrid balanced cable and the sound was soooo yummy :dt880smile:

Let's not derail with a burn in debate. If you hear it fine, if not fine.

I concur. Let's keep this limited to impressions.

I just switched to the velours for the first time. Possibly the best pad attachment system I've seen in some time. Easiest to change out for sure. About five second per side and had no idea how the mechanism worked. Bass seems a bit toned down with the velours, tighter and a bit more polite.

Well maybe you did not hear any difference but I certainly did. The headphone out of the box sounded more closed in and less appealing than it does now. The differences started at 50 hours. YOMV this is my impressions and it been stated in my review as well. Most people looking to buy a reference headphone are more experienced and not new to the scene. In my 37 years of listening and reviewing equipment I am in the burn in camp. There is noticeable improvement in my opinion with hours on the PM-1. Sometimes people who buy new headphones or amplifiers are not patient and putting the proper amount of hours on equipment gives them a better perspective on how something can really sound. Whether you hear it or not and dont think gear changes is your impression and mine is that it does.:biggrin:. Your entitled to disagree as I totally disagree with your statement that there was no difference in the retail version. In my pair the difference was very noticeable.  Seem like there are people who are getting the headphones who agree with my evaluation.

Just switched back and forth a few times between the velour and leather. You definitely give up some sub bass on the velours. The leather sounds better overall even disregarding the sub bass difference. The velours seem to add a bit better sound stage though and are stupid comfortable.

The cable on the pm-1 is just about perfect IMO. The connectors are tight but easily detachable. The primary length of cable after the split is housed in a nice soft but rugged jacket. The jack itself is largish and sturdy 1/4", possibly a Neutrik but not sure, with the Oppo logo. 

 

Are you paying attention hifiman? You need to fashion a cable like this for the new line.

The great thing about the pads is it so fast and easy to switch them. Companies should benchmark how well this system works . The PM-1 is one of the very best build designs I ahve seen. i do not think there is another headphone that has the total design quality if the PM-1

It still confounds me that this is their first hp. :blink:

I've had my PM-1 for about almost a week now and I will have my impressions/review posted probably within a day or so.  Just gathering and organizing my notes.

post #1694 of 3442

Dang, three post in three years. I'm expecting the review to be quite epic. :tongue:

post #1695 of 3442

Don't hate.  :)  It's already turning out to be a lengthy impression/review!
