I have a set of early/mid 80's Revox 3100 headphones (DT880pro OEM) on their way to me from flee bay.
They definitely need new pads... so my question is... which of the available pads will sound most "original" and which will sound best .... (and why)... I was once familiar with them as I used to sell them new in those days..... but my sonic memory isn't up to a 25 year break!
From what I can find online and on Head-Fi - the options are:
- Beyer Grey Velour 880/990
- Beyer Black Velour 880/990
- Beyer Black pleather 770
- Beyer Black pleather aeronautical
- Jmoney Leather
- German Maestro 41-6051 pleather
- no name from http://stores.ebay.com.au/15shopgoods
Also some notes:
Reviews of the aeronautical have stated poor SQ results - the JMoney have good results, they are similar in materials but the JMoney pads are thinner (thickness) and perforated at the back (these were all with current/recent DT880's - not from 1980's)
Photos of the German Maestro pads are not definite as to whether the back surface is porous (similar to perforated) - although they do show a single perforation on the bottom (may be semi sealed with the one perforation?)
The China based ebay store seems to be advertising leather or pleather http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=350323949159&ssPageName=STRK:MEWAX:IT#ht_2358wt_1027
Back side is not shown so it is not clear whether the back surface is perforated.
The original Beyer velour pads are perforated on the rear.
The perforations seem to be important to sound quality... at least with recent generation DT880's
I have no idea whether the original DT880pro's had perforated or sealed pads (maybe someone could check?)
Any advice would be much appreciated - I would like to start out listening to these babies in as original a form as possible.... then I may consider modding if and only if I am dissatisfied... (I remember them being fantastic - and in many ways on a par to the Quad Electrostatic speakers I used to sell - and that I later owned for 15 years)
