Guys, sorry for the newbie question, but what are normal and pro bias jacks? I recently acquired an SR-007 mk1 and is looking forward to purchase a BHSE. I know for a fact that SR-007 mk1 requires more power to drive than the SR-009, and that BHSE has two headphone outputs.

 

1. If I were to order a BHSE from Justin now, how will it be configured by default?

a) two Stax normal bias

b) one Stax normal, one Stax pro bias

c) two Stax pro bias

d) one Stax plug (which bias?), one Sennheiser (which bias?)

 

2. If the SR-007 mk1 were to be my primary headphone, what is the optimal way to configure my BHSE and which bias should I use? I read somewhere saying that one should always use the pro bias for SR-007 and SR-009, while others said the normal bias has a higher gain so the SR-007 should be used with normal bias. I also read that having normal/pro bias will result in a different sound compared to having two pro bias, even if I use the same pro bias plug. Which is true?

 

3. Does normal/pro bias have anything to do with the number of pins? The SR-007 mk1 and SR-009 are 5-pin, while older discontinued headphones are 6-pin. I don't think I would use a old 6-pin Stax headphone, unless Stax decides to release their next flagship headphone with a 6-pin.

 

4. Most importantly, just what is the exact difference between normal and pro bias, and why is this important?

Unless you have the Senn HE90, I would go with the dual Stax Pro jacks

I ordered my Silver BHSE with the Stax and HE90 jacks. I don't need to use both at once, and while I don't think I'll come across a HE90, if the rumored new Senn stats ever make the scene, I hope to be able accommodate. I also ordered the SR009 from Justin. I hope they come together, I have no other stat amp, or stat at this point.

Hello Justin

 

Will Santa Claus bring a few BHSEs -mine, for instance- in his sack? What a merry Xmas it would be!

 

Best regards anyway

I ordered a secondhand BHSE from a guy living in Seoul. These are the pictures he sent me. He told me that he is also sending Psvane EL34PH tubes, which are different from the black tubes shown in the picture.

 

 

 

 

It looks like it is a Stax/Sennheiser unit. Will it have a problem driving my SR-007 mk1 compared to a BHSE with two Stax pro jacks?

The outputs are daisy-chained so there's no difference

Can anyone identify those matching disks the amp+PS are sitting on?

post #4388 of 6018
Don't know those. I got 2 sets of 4 simple black disks from audioadvisor in anticipation of my amp/psu.

Thanks AnakChan, I particularly like the style of the ones in the photo, but the ones you posted are pretty nice too.

Wait, so you guys are telling me that those metal disks below the feet are not a part of the stock BHSE package?

The table is extra too.
