post #3796 of 5887

I didn't think it would be a problem but worth asking I suppose.

If you are referring to the electrostatic bias voltage then that isn't adjustable.  They are fixed at the time of production for the given outputs.  If you are referring to the offset and balance adjustment for the tubes (sometimes called biasing though it isn't really true here) then they can all be adjusted. 

 

If you are using a preamp before the BHSE then just max out the volume control.  Then just a tiny part of the resistive track or one resistor is in the signal path which is pretty much the same thing.  One more on a few dozen doesn't make any difference.

^ Spritzer generally speaking, do you think it is better to adjust the volume from the DAC or from the Amplifier? 

 

Does a good attenuator or pot like the RK-50 change the general rule? 

 

I know this has been talked to death but maybe it's time for review . . . I was never quite clear as it applies to the BHSE or GS-X mk 2.

In my experience, using a preamp or any kind detour from the source to the headphone amp adds a layer of grunge (to varying degrees) that is annoying.

More interconnects or another attenuator or even a connector between 2 interconnects is audible, makes things sound less direct and muddy, and is just plain bad.

I tried this many times for various reasons and gave up on it.

I don't even like using Stax extension cables (I found it muddied up the sound on Lambdas, SR007s and 009s using 3 different stax amps).

So I need to sit close to my amp.

Because my GS-Xmk2's volume knob is at arms length, I use that when changing the volume, but because my BHSE's volume knob is further away, I turn it on full then use my sources attenuator which allows me to alter the volume by it's remote control.

^^^ I agree with this.

Keep the signal chain simple and (reasonably) short as possible.

I find it essential to have the freedom to be able to walk around when listening. On my first stax system, I used the 5 metre round extension cable, giving a total of 7.5 metres. But it did muddy the sound a bit, so I upgraded to the 2.5 metre signature ribbon cable, giving 5 metres of ribbon in total. That was years ago, and I have deliberately never compared the sound with/without extension because I don't want to become dissatisfied with something that I can't change. 

 

Despite 5 metres of not-especially-expensive cable at the end of the chain, I can still easily detect differences between interconnects, power cords, etc, so whatever may be the limitations of the extension ribbon cable, I'm assuming it's still pretty transparent - and nobody is allowed to say otherwise :o)

I have the SRE-950S which I use occasionally, and to my hearing there's no difference in SQ between using it and not.
post #3804 of 5887

Actually,  longer cables I have found are fine (IC, Headphone  cable, even speaker cable), but adding extensions and new connectors is what's bad.

I have 15-foot Moon cables on my dynamics that allow it and they sound great. I wish Stax would offer a longer original cable option on their phones.

I suppose it is all a trade-off.  Get the 2.5 meter extension with some decrement to the SQ, or sit uncomfortably to be close to the amp.  (I did get the 2.5 also).  In another example, I use an equalizer (Rane DEQ 60L) between the DAC and AMP.   For me it is a trade-off between vastly increased clarity, and sound stage at the cost of some detail.  When I get my BHSE I'll be using an equalizer on the computer so the linkage from DAC to AMP will be more direct.

 

BTW, lest you all think I'm a total audio heretic, the equalizer is needed to correct quirks in my hearing, not my gear! tongue.gif

Maybe because that BHSE is the king of amps. :)

It's true that the BHSE is quite an amazing amp, ( well IMO it is ) but I can't see any reason why there would be a difference in SQ when using a Stax extension cable with any other amp.

Just what my ears tell me. With my old 007t/SR007 mk 1 system, it was night and day. I'm just theorizing that the amp was under-powered for these. They sounded weak.

With my 009s and my 007t/ii, the difference is less stark, but the 009s pick up everything in the chain, and there is still some weakness with the extension and some of the

details slink into the background.

I've never used a Stax extension cable with a Stax amp so my apologies. Head-fier Realmassy is bringing his SRM- 600ltd to my place to compare it to my BHSE, so I might try my SRM-950S with that amp. I still don't think there'll be a difference in SQ when using the extension cable with Massi's Stax amp because I've found the source I have is a boost to any amp.

Sorry, I'm only guessing when I said my source is a boost to any amp. I have found that with the three headphone amps I have though.
My amps are BHSE, GS-Xmk2 and Pico Slim.
