^ Totally agree with that. Though I must say first 20-30 pages are absolutely mandatory.

I agree. It's been fun for me. Has it been fun for you? Of course it has.
 
Oo-- how about this: think of the sustained current capability of an amp as being analogous to torque in a car engine. Hah? How about that?

H, i if any of you are interested,  this is my attempt at open orthos,  drivers are from hp3's, they have lost a bit of their original thump and I will have to keep trying various felts to try and restore it,   because it was really good in the original cups with a different damping. They still sound good and accurate in the open cups, but the bass was really good. The main reason I decided on a transplant was for comfort, and these are very light and cool. Hopefully the attached pic works, and any comments or suggestions would be great. BTW has anyone seen these phones before,  as I have never seen any comments about them on headfi,  and searching for their product number yeilds zilch . They are over 20yo and are ROSS re2330 made in britain,  This, to me,  is the most interesting thread on headfi...... cheers

I see you still use quite considerable amounts of damping. Did you have a try completely without already? I quite liked the HP1 systems coupled with foam pads, with nothing but a 75% micropore sealing on the rear magnet.

Hi, yep tried holding the drivers up to my ears before installation, covering with fingers and felt,  and found that with the center of the driver slightly uncovered was good. I then covered all but the nine center holes,  with a felt that sticks on furniture,  to stop wooden floors from scratching. This was almost sibilant and not enjoyable to me, There is a pic of the previous setup that I did like,  on page 1083,  and I am only trying to get more comfort,  but with a similar bass impact as I had before, I think I have micropore tape (hospital tape that breathes) and will give that a go before trying some other felts. thanks for your suggestion ....cheers

I've just put the micropore'd HP1 systems onto some Superlux HD660 (the Dt770'2003 lookalike) baffles, and equipped that with various Beyer pads. The results were very promising, the sound is as rich and exciting as with simple HD414 foam pads, but the treble gets tamed, and you get much more airyness.

 

[ujamerstand]

How much did you buy the HD660 for? I'm looking for the headband.

 

[nickchen]

Yep, the headband is the only thing of interest with these cans, as that is the only thing unavailable at the Beyer spare parts online store. Got a pair for 39€ incl. inland shipping at german ebay. Otherwise, you pay 50ish (e.g. at Thomann.de).  I've heared rumours that this headband/housing design will be continued in form of the Superlux HD330. I bet that thing will sound even more awful than the HD660 when being used as headphone...

Yep I like some of the superlux range, the 660 looks a bit hot and heavy to me. I would prefer their akg lookalikes. Hey is micropore tape the stuff used in hospitals?

Nevermind google just answered the question

 

[zaphod373]

Yep nickchen, you were pretty spot on, they sound very nice with tape and nothing else, thanks a lot

Haha, you know the reason why I'm interested in those cans. I can't seem to find any store that carries them in North America though. I remember seeing one store that carries it for around $70, but thats way more than what I would pay for a single headband.

I have the chance to buy a Yamaha HP-1. What should be a good price for them and is there anything I should keep in mind buying them?

 

[wualta]

Any chance of seeing/hearing/touching them before you buy?
 
Oh-- for anyone tempted to use stick-on felt: remember that air can't get through the adhesive layer, so you're effectively sealing the driver with something reflective. The result will be screechy, to use the technical term. Zaphod, your HD 414-clone headset looks great. That's the kind of enclosure Yamaha should have started with, then tuned the driver to suit. It would have played to the driver's strengths.

Guess not...
