There's the reason. You're manufacturing an internal conflict, the tension from which is making for a perceived more intense listening experience.

It's 580v down to 480v but do remeber to discharge the phones while checking for differences since they can hold a charge for a while.

i ve got another quick question...

i just bought an srd-7 from a fellow head-fier thinkink it would be an upgrade (following Audiocats advice). now i just saw Spritzer wrote somewhere that the srd 7 and srd 6 have same transformers and circuit.

now who says right? i m all mixed up

has someone ever took out the top of both to see inside?i wish i can cancel the sale on time if they are they same.

 

[Duggeh]

Not understanding what you are buying really isn't appropriate reason for asking for a void on the sale in my opinion.

 

[pidesd]

i read the post from spritzer just after i bought it

i hope the seller will be kind enough to cancel the sale. and at the price he sold it to, i think he ll be able to find someone pretty quickly.

Absolutely true statement.

 

[Tachikoma]

Well the SRD-6SB sounded like **** to me while the SRD-7SBmk2 was acceptable. Just judging by the size of their enclosures can they really be using the same transformers?

They sure look identical and the transformers in the SRD-7 are only half the height of the enclosure:



I just bought a SRD-6 so we'll find out...

 

[Victor Chew]

Just thinking out loud, if the transformers are the same (SRD6SB and SRD7SBmk2), I can only think of the speaker wires and/or the selector that is causing the sound difference. The bias should not be making such a big difference if the voltage is the same. Moreover both are SB as well. Unless the transformers look the same but are different internally from use of different components (ie. the core, and the quality of the wires, presuming that the windings are the same).

 

[Sherwood]

The selector wouldn't be in the signal path, would it? It should only have a very minimal impact on the sound, if I understand its function correctly.

 

[spritzer]

The switch shouldn't matter but Stax could have deliberately done something to the SRD-6 to sell the more expensive product. Certainly wouldn't be the first time something like that is done but I'll rip mine apart when I get it an post about it.

 

[pidesd]

as far as i understand it, the switch is only a selector for the ground path, so in an unbalanced configuaration it will not affect the sound.

also, i notice that when i wire the transformers directly to the input wires inside my srd-6, the sound improve quite a bit, thus bypassing some kind of protection resistors in the signal path ( not sure about these devices called PTHbd4r7m murata)

btw the srd-6 trafos (the volume of the taped portion) are 1,8*2,3*3,0 cm approximately. if the "taped" area is a sushi slice, then 1,8 cm would be the slice spacing(best analogy i could find

)

Couldn't the driver from Mjölnir Audio surpass Stax in parts and sound quality?

The switch actually switches all four wires at once so that the transformer can be used with balanced amps. Not all SRD-7's are like this though so I modeled the return path of my board after those with a shared -. It's easy enough to just not use the board connections.

Those things are thermistors, 4r7's to be exact. I left them out since as you can see in the pic above, I prefer a direct in/out approach. Those transformers have also had the wiring replaced right to the windings, not something I recommend doing.

The primary is easy enough to work with but the secondary wires are thinner then a hair...

Hehe, the new bias board works better with the newer Stax phones and when used with better transformers, should be quite a bit better.

Quick canvass of opinion: which would you consider a better 'all rounder': original Lambda, or 404?
