what the...? are you an engineer at superlux or something? biggrin.gif

those cups look amazing man, but i don't get where this is going to go?

the new wonder hp? seems like you have some serious skills.

 Lol, no, I`m just curious how this turns out, doing it for fun :D Everything except HD-662F elements are going to be replaced by wood/aluminium. It`s going to be dual-entry cable and pads are probably going to be angled for my head shape. Element grills are off-copy from originals. Nothing to be wondered about but I hope it comes out at least as good as original HD-662F. Designer/woodcrafts is my speciality btw ;)

Anyone tried the 664 yet?

I thought the MKII mod was a DIY thing?
Why is Superlux mentioning it on their website?
(btw, the features section in German has been removed)

can anyone answer this? what the heck does MKII means anyway? Mod the Kilo IIHz or something? haha... and is it patented biggrin.gif ?

In case of production/advertisement it`s probably same series headphone which has been upgraded a little to address it`s "problems".

 

In case of modding, it means certain filter mod for HD681 for example (medium mkII hardware filter).

 

I`m going to put some info (collected from RG forum modification thread) into this thread for everyone who want to mod their HD-681 (red rings) or HD-662F:

 

Link to HD-681 modifications thread: http://rockgrotto.proboards.com/thread/4769/superlux-hd-681-modifications

 

Link to HD-681 medium mkII filter: http://rockgrotto.proboards.com/thread/4769/superlux-hd-681-modifications?page=26&scrollTo=70109

 

Link to HD-662F filter mod: http://rockgrotto.proboards.com/post/124411/thread

 

And here`s detailed information about filter components:

 

 

Quote:
Filter components:
 
Resistors: 
 
use wirewound, Metal film, carbon whatever you like or feel will be better.
 
Not of any importance really in this application as long as the wattage is 
ABOVE 0.25W (which most resistors are)
 
 
capacitor 1uF:
 
Multicomp MCRR50105Z5UM00050 = Farnell order code 121-6447
 
or:
 
Multicomp MCRR50105X7RK00050 = Farnell order code 121-6443 (used by me)
 
or:
 
AVX SR305C105KTR = Farnell order code 110-0398
 
or:
 
AVX SA305E10MARTB = Farnell order code 110-0420
 
 
 
Inductor (choke coil):
 
 
EPCOS B82144A2474J = Farnell order code 517-070 (used by me)
 
or:
 
EPCOS B82145A1474J000 = Farnell order code 164-4331
 
 
or any other small coil, inductor, choke with 470uH and a resistance of 
equal or lower than 2.5 Ohms.
 
 
 
------------------------------------------------------------------------
 
 
 
Only the resistor values are to be altered.
 
You can vary the resistor value 
of R3 and R4 (now 39 Ohms) between 27 (to little damping of high freq) to 
120 Ohms (a bit too much damping of high freq.). You can put a 100 Ohms 
potentiometer in it's place and fiddle with the settings for instance.
 
 
 
If the resistor value of R3/R4 is between 25 and 50 Ohms use 56 Ohm resistors for R1/R2
 
If the resistor value of R3/R4 is between 50 and 75 Ohms use 47 Ohm resistors for R1/R2
 
If the resistor value of R3/R4 is between 75 and 150 Ohms use 39 Ohm resistors for R1/R2
 
 
 
The capacitor and inductor need not to be changed as these are the frequency 
determining parts of the filter.
 
 Resistor R3/R4 determines the Q factor of the 
filter AND amount (dB) of filtering at the filter frequency.
 
The center frequency is around 7.2kHz.
L1,C1,R1,L2,C2,R2 are for compensating 
the impedance peak which is caused by the filter network L3,L4,R3,R4,C3,C4.
 
 
You can leave L1,C1,R1,L2,C2,R2 out IF you want if you are ONLY going 
to use these cans on a low Z output amp (around 10 Ohms). 
 
In all other circumstances (output impedance between say .. 20 Ohms and 600 
Ohms or unknown) this part (L1,C1,R1,L2,C2,R2) of the filter network is ESSENTIAL 
in obtaining the right amount of damping.
 
 
 
------------------------------------------------------------------------
 
 
 
maximum highs, sibilance gone HD681 character remains (first filter):
 
R1=R2=56 Ohm
R3=R4=39 Ohm
 
 
 
slightly less treble but still close to original HD681 character:
 
R1=R2=56 Ohm
R3=R4=47 Ohm
 
 
 
less treble but still brighter then Sennheiser signature in general (second filter):
 
R1=R2=39 Ohm
R3=R4=56 Ohm
 
 
 
About equal to Sennheiser signature in general bass more prominent:
 
R1=R2=39 Ohm
R3=R4=82 Ohm
 
 
 
------------------------------------------------------------------------
 
 
 
Capacitors:
 
 
Some say polyprop sounds better (in this picture).
Some will say mica or 
silver-mica is better, yet not available in these values.
 Multitlayer ceramics 
(X7R is preferred over Z5U) are small and can be used inside the headphone without 
taking up too much space. There are also smaller sized polypropyline avaiable.
 
The voltage (which determines the size) is not of importance. 
 
For external filters 
the sky is the limit (money wise) and can be constructed to your audio religion.
 
 
 
------------------------------------------------------------------------
 
 
 
Q: For the orginal HD681 filter from the very first page, say I want to attenuate 
the ~7.25 kHz frequency 3db rather than 6db? I replace the resistor in parallel 
part of the filter with one of lower value correct? What value would I use? 
 
 
 
A: Parallel filter (the one in series with the driver) between 27 and 33 Ohm
series 
filter (on the input of the filter) R = 68 Ohm
 

 

Have fun modding your HD-681 or HD-662F ...I`m loving these cans! Filter modded HD-662F = great neutral balanced headphone for analytical & studio listening. Filter modded (medium mkII filter) HD-681 (red rings) with velour or custom pads = great dynamical and fun sounding (not muddy) with little extension in both, highs and lows, with great mids section and large clear soundstage.

 

 

Soon Frans is going to release modding guide for HD-681 EVO too.

661's cups + evo's headband ?

photoshopped?


No, I got this from Superlux website. HD664. Most likely this is the "EVO" of HD661. But I haven't seen anybody who has it though.

Would these work as replacement pads for the 668b and whatever has the same cup design?

HD664 = HD662 MKII updated according to their page.

Hi guys I'm a bit overwhelmed about all the info and reviews out there about the superlux so may I ask..., In your opinion what superlux model is the best for monitoring (flat/neutral sound)? It has been said for sure along the 42 pages but didn't find anything at a quick glance. Thanks in advance.

HD662F with filter mod for highs or 668B. Also depends if you want closed, semi-open or open cans?

I have 662F for sale, with velour pads. If anyone wants them PM me, New Zealand or Australia preferred but other places considered especially if you pay postage.

post #674 of 987
Anyone performed a head to head of the 661, 669, 668 and the B, F and Null of each?

Any great differences between them? B is supposed to mean balanced, F full range. Null, no idea.

The 681 evo has all three of these qualities. There is no veil, it's relatively neutral with a bit of a fun bass boost(nothing intrusive, it just extends very deep)
Some complain about the highs still...I find none with them. No listening fatigue here

 Second this.  I now have about 160 hours on my 681 evo's and very pleased with the purchase.  I'm still shocked at how good they are for such a low price!
