DC offset is 2v and 8.5v, measured between the channels. 1.1v and 8v between + and ground. Should I adjust the offset?

 

You can't directly measure the bias because there is a large series resistance with it, and that acts as a divider with the resistance in the meter. You need a high impedance meter (ideally an electrostatic volt meter), or knowing both the impedance in the amplifier as well as in the meter and doing the math.

 

As for the offset, I personally wouldn't care about numbers that low. You certainly could adjust it, though.

Yeah, that makes good sense. Thank you very much. Some time I'll measure the caps too, just to check whether they need replacement. I suppose a measurement of the resistance and capacitance would do? And what numbers should I expect when doing the measurements? Anything else I should measure too?

 

I don't hope I am too demanding ;)

You only need the resistance to measure the voltage. The capacitance can be assumed high enough to not be an issue with the load of the volt meter.

 

Measuring the capacitors would simply tell you if they're going bad, which might be a good test if you're at all wondering. You might have to take the capacitors out of circuit to measure them, though.

Ohh well, you know most people say that a recap is a good idea for such an old unit. Reason for measuring resistance is of course to see if they bleed DC, capacitance of course to know whether they are within spec.

Hey guys, I've got a sr-202, and its cable seems to be going.

Sound distorts when I move the cable around.

I was wondering if I could use the cable from an sr-x mk2 as a replacement, and how hard it would be to perform the replacement.

Thanks!

I have a solder station, although not much experiance using it.

Not worth it, just spend $80 on a replacement cable which is a direct solder in, no need to modify a normal bias round cable to run fit for pro-bias.

Just received a pair of 007 mk1's.  I am preferring them to the mk2's.  I'd agree with the impressions I've seen on forums regarding both models.

They just are more "balanced" than the MK2s. The bass goes deeper and is better controlled and they're a bit more coherent overall. Congrats!

The SR007 MK2 sounds somewhat boomy compared to the MK1. They are still the best Headphone I know and there is a good reason that they still cost 200-400$ more than the newer model.

Boomy could be related to that attenuated mid bass, at least for me and few others. If I had the option I'd own both because I prefer the MK2 over the more balanced MK1 for select few genres.

Agreed with this.

What genres?  It's good to see someone actually likes the MK2s for something.

I like my Mk2 (2.5 really) quite a bit, but then again I've never heard the Mk1 smily_headphones1.gif

On music with a strong rhythm element (pop, rock, etc)  the Mk II's sound a bit over-ripe in the 80~120 Hz region ("boomy.")

 

On orchestral, chamber and other "classical" music they sound "warm."

 

I think they are voiced for "serious" music lovers who want that "rich" or "warm" sound.  Just my 2 cents worth.

 

All versions offer lots of detail low distortion etc. But the later models do have a different voice.

Actually I think the MK2s are great headphones, just a few steps backwards from the MK1s.
