    Stax SR-007 MK 2.9

    Headphones have been babied for the past few years and are in excellent condition. The blu-tac mod has ostensibly been installed, but I have not verified this as I'm not the first owner. Includes box, carrying case, and documentation. The headphones are also listed for sale on ebay...

    Good DAC for Stax

    I got me some SR007's. I have a modi right now but it's having some issues and is definitely holding my system back. I want a standalone USB DAC that is transparent, clean, and precise for under $400 (tops!) I want to buy used if possible, and would prefer something other than Schiit this time...

    Schiit Lyr 2 with several tube sets + Modi Multibit DAC + Non Fazor Audeze LCD2 with custom cable COMPLETE SYSTEM GREAT DEAL!

    The Lyr has a pair of the stock tubes, a pair of reissue ECC83 Genalex Russian Gold Lions, and a pair of NOS Amperex Orange Globe 6DJ8 tubes. Also, a pair of Tubemonger socket savers is included. Amp is in good condition with small blemishes and scratches (will provide additional pictures if...

    Now you have caught my interest. How much, more or less, would the components for such an amp cost? Is there a BOM and schematic available for such a device? I don't have anywhere near the time to do this, nor do I have the knowledge, but I would fo it down the road.

    A little knowledge about the most dangerous components of an amplifier goes a long way. As for the biasing, I've only biased the T1, so IDK if the internals are similar. But I never was turning the adjustment pots all the way. I was doing very fine adjustments while looking at the multimeter...

    The Stax Thread III

    With proper amplification, the Sr007's (i have mk2.9 bass port modded, apparently like the mk1's) are the most "liquid" headphones I have tried, and I have a fair amount of listening experience with hifi/midfi gear. Nothing harsh about them. The gentleman I bought the headphones from also had...

    Alright Stax mafia: modded T1 vs every other common amp stax has produced driving sr007. Who wins?

    Schiit says the Lyr 2 has preamp outputs for speakers. Am I missing some difference between powered speakers and a headphone+amp combo?

    Who needs heating in their home when you have an amp like that? Hot damn.

    Let's be clear: these are both world class pieces of equipment (Sr007 and T1), so they sound fantastic compared to basically anything else. If you wanna audiophile nitpick like we all do, then yes, there is a slight bit of confused bass that my ears picked up. I could live with it, but I wanted...

    I don't have the l700. From what I have heard, however, the L700 is a bit like the sr009 - meaning more treble and less mids. TBH, the sr007 sounds a bit muddy with the T1. However, you can mod the T1 to improve ita performance (something I'm doing right now and have yet to hear thr results of)...

    Resoldered the new resistors, voltage checks out at 16 and 22 v from the batteries. I have applied the ceramic mounts with thermal paste to the heatsink, but am unsure how to apply the mosfets. Do i put thermal paste on the back of them and then press down?

    Yes, I very much do like their sound. The amp...not so much, which is why I'm modding it now.

    Thanks. What differences in sound exist between these two editions?

    I bought a used pair recently and have no idea how to tell. They're also port modded so IDK what the difference between port modded MK2 vs MK2.9 would be.

    How can I tell if I have a pair of Sr-007 MK2'S or Mk2.9's?

    How do those cans sound, anyway? I have a feeling they're more a collector's item than anythinh else.

    You have to tin the leads before you apply solder. Otherwise the solder won't connect. Also, you want to use flux or rosin core solder.

    OK, I'll do that. Much appreciation for your help. Hopefully that'll be the last piece of the puzzle for this project.

    ohhh I see...you got that using ohms law. Is there any reason why one wouldn't just measure the voltage across the resistor?

    I completed the soldering for the ccs's. For better space use, I moved the 10m90's above the DN2450's. and unless there is a reason not to, will forego the use of the l brackets and just mount the 10m90's on the heatsink. When testing a circuit, I found myself confused on where to measure the...

    @JimL11 Thank you, that answers every possible remaining question I could have about the project. I'll finish it over the next couple of days and let you all know how it goes.

    Yes, it was great advice to get the O2. The most important thing I learned was to look closely at which components have a polarity which needs to be paid attention to. It also taught me how to read resistor impedance values and better soldering skills in general. Much appreciated.
