Thanks for the advices!

Stax SR-007 earpad can rotate freely, and the earpad has a straight taper on one side ("D”-shape). What is the standard orientation？ What is your preference？

The original Beyerdynamic DT990 600ohm

Have you tried any replacement earpads for this SE-300? Any good ones？ Thanks!

ELEGA DR-86CII 8ohm This DR-86CII is much more "monitor" than my DR-631. The clamping force is stronger and the shapes of their earpads are different. Really like the black-sliver colourway. A Japanese web site introduces some ELEGAs: http://newsmuda.blog72.fc2.com/blog-entry-1421.html?sp

Just playing my two Pioneer SE-300, they sound quite differently. The previous one is like a bass heavy version, this new one is more natural with better highs and details. Although the earpads are not in the same condition, I don't think it makes this huge difference. Very interesting...

Pioneer SE-300 -- Piezoelectric Stereo Headphones (1972-78) I like the sound of SE-300, just got another one. The pleather earpads have peeled off... searching for suitable replacements...

Philips ELECTRET N6325 Play with these 2 electret headphones this weekend.

Philips ELECTRET N6321

It is still my favorite IEM, 2 broken and 2 still in service. Very good sound isolation, super dynamic, warm and musical, great for Basshead. Another 2 favorite IEMs. Stax SR-001 Sony MDR-EX800ST (still in production) I don't think many IEMs nowadays are worth the price...

Sony MDR-NC10 1995 — First Noise Canceling Headphones

Also playing with these "modern" monitors these days.

Play with my Beyerdynaimc DT48 VarioCup these days, I agree with your comment "It (Elega DR-631) sounded like a fuller, wide, more detailed DT48". Comparing these two monitor legends, DT48 sounds a bit metallic...

I am curious about how a 10k ohm version sounds and the amping condition.

Nice！

T70 (250ohm) with EDT 1770 Velour Coolmax pads, is the best vocal "old" Tesla. It looks cool with DT1770 Pro headband.

For all Beyers, I prefer original earpads, except T70 (250ohm), pairing with EDT 1770 Velour Coolmax is much better.

Original pad sounds the best. The Beyerdynamic EDT 770S Softskin is one of the better alternatives.

Listening to this ELEGA DR-631 these days, I would say it sounds "REAL", other headphones are "HiFi" / "Sound Effects". "REAL" is the most appealing...

Coral E-80 (1976)

Sony MDR-SA3000 Sennheiser HD8xx ancestor... :relaxed: Service manual shows that SA3000 & SA5000 share the same driver (Part No. 1-542-603-11)

Beyerdynamic DT231 Pro Very very very good performance for its price. Lovely vintage Beyer tonality!

Thanks!

ELEGA DR-631 8ohm Very beautiful! Well built! Good old days...

I got this Beyer DT200 from Japan.
