So it seems the best way around this in making a DIY cable for the HD 650, is to terminate it in 4 pin XLR (male), then create adaptor cables for different amps using 'Female 4 pin XLR' -> 'Terminal of choice'

 

An easier option is to spend nearly 3x as much on the official balanced cables, but that's more effort on my half (you expend effort to gain money, waiting is also an effort)

The above diagram is for balanced cables used for components going from 3 pin XLR to a 1/4" jack (not to be confused with stereo) and is not the correct config for balanced headphones, for head-amps that require dual 3 pin xlrs, pin 2 is the positive for both the right and left signal and pin 1 and 3 can be combined for the negative termination.

+1 Thanks for clarifying the above and also putting things in context!

 

Itchy fingers have already braided the cable.. Something tells me I'll have a new handmade thing by next week.

Has anyone tried the Bottlehead Mainline with the HD650?

I was away from my HD650 for a couple weeks but tonight when I came back to them, I was shocked to be reminded how much they sound beautiful. They always bring smile to my face!

No problem

 

Here’s another diagram from Brysyon’s BHA-1 manual, although it may be a bit confusing if your using it as visual reference while soldering the wires, just make sure you follow the number scheme.

 

The HiFIman one makes it a much clearer as the right #3 and left #1 are in real life reversed on the amp's female xlr as shown below.

Interesting read about the compensation curves of cinema the X-curve:

 

http://lenardaudio.com/education/17_cinema_7.html

 

This is the exact same curve I would use on my Denon D7000s.  I found the discussion about pink noise quite interesting.  It's all starting to comply with my experiences in audio reproduction.  There are a fair few curves going around - all slope down the top end.

 

Only once, ever, did I ever go into a hi-fi showroom - I think it was a KEF dealer, and the music playing was beyond reality - into music itself.  I remeber walking in and being just astounded by the sound...more importantly by the ambience in the room...the only way I could describe it in my mind was that the ambience was "pink and purple"...I don't know how or why...but mental imagery has always been a fundamental process in translating what I hear in sounds in to words.  The fact that "pink" noise is used to calibrate cinemas suggest that I'm not the only one to 'sense' this phenomena.

 

I am learning all this from 'DanDan' Fitzgerald - who claims:  'For what it's worth I am the best mixing engineer on the planet'

 

I am starting to believe this guy.

 

That is why I had always kept my HD650 and K701 ... all professional recordings fell in to one camp or the other (compensated/uncompensated).  Except the K701 had no bass and a resonant upper midrange...I guess in dandan's case it would have been HD650/HD600.

 

But it still comes down to one thing...throttle position.  How do you want it?

Another interesting article from the same website:

 

http://lenardaudio.com/education/14_valve_amps_7.html

 

And I quote:

 

Music. Pre 1970s many if not most large manufacturing companies maintained a strong class demarcation of management against trades and production workers. This demarcation was also reflected in music. Management including the academic class, was identified with Classical and Popular conservative music similar to Frank Sinatra or Julie Andrews “The sound of music” etc Middle class music was mostly mid range with minimal bass energy. The working class identified with music of the devil, Sex drugs Rock’n’ Roll, Jazz, Blues, Fusion, music with intense bass energy.

The rock recording industry noticed that the new Solid-state amps caused most speakers to sound flat and lifeless. Without any standards in place, recordings had extensive EQ applied to boost the bass and hi-frequencies to compensate. Many guitar and bass amp designers also noticed that the new solid state amplifiers (with 100% Damping factor) had a suppressive effect on the musicality of a speakers performance and stayed with Valve technology. But academic engineers of HiFi amps were blindly obsessed with the almost perfect zero distortion figurers and 100% damping factor solid state amps could achieve. The concept of allowing variable current drive to enable solid-state amps to emulate the higher output Impedance of a valve amp to manage speaker Damping, was negated.

 

Can't these elite humans leave us poor people alone with our broken backs, devil music, bass and tubes!!!  :D

Problem is though, I can't decide whether or not I should upgrade my SRG2s to the Ultra-Linear. I LOVE the Sennheiser veil and the dark texture of the 650 so I'm just worried that the ultra-linear with a bit more treble energy might mess up the reason I love my 650s :(

At a show, and just let me say, you had better have $1000 sitting around you don't need before you listen.

post #15930 of 20548

I haven't listened to my HD600's for quite a while, been listening to the HD650 and HD700's. I put them on again last night and I hate to say this but I really don't like them much any more. The mids and treble are okay but the bass...where did it go? Anyway I don't need this many phones so I think when I have my clearance sale the 600's will be going. I even like my HD580's more which I didn't think I'd ever say.
