If it were a new unit... maybe it won't have these problems... don't know... They will send the unit back to STAX when you send it back to them. It's the same thing after one year manufacturer warranty. They will send it to STAX for out of warranty repair for a fee depending on the problem.

  well... as I said, as far as I can tell, it is factory sealed, unless you know how to put that migical plastic seal thing over the box and still stuff it into the paper box. You can keep saying that to yourself, but the fact is there is QC problem here. As I said, otherwise they...

  hmmm not sure about that. I just received my pair yesterday and new out of the box, the left driver has severe hissing.... after taking off the earpad and the metal mesh underneath I found quite a bit of debris on the driver assembly. After blowing it off, the hissing was gone. However, it's...

  Impedance has little to do with efficiency. Lower impedance will make headphones easier to be driven with lower voltage source (portable source) because output wattage equal voltage times voltage divide by resistance. Efficiency means the amount of wattage that's converted into sound pressure...

No idea how you came to the conclusion that it's the safest solution. I would take proper current limit at the output any day over a shut off at PS. There is a reason it's the only stat amp that's doing it and no, it's not because others can't do it. Also, yeah, personal attack, you must be a...

  :facepalm:

Well... the person who had short underneath the cap is probably me.  That's what happens when you give a potential path to ground on top of a trace carrying roughly 650V of unregulated DC. Silkscreen coating isn't going to cut it.  After installing some Kepton tape under the cap, everything is...

no need to go for 1968LS if you don't want to. For stability, it's just fine. The voltage drift is just a little larger than 1968. About 40V difference from startup to completely stable, which takes about 20~30min for the off-board version. You shouldn't have any problem zeroing the offset using...

Since gilency is bringing his newly built KGSSHV, I probably won't haul mine over there then. Instead, I will try to finish my balanced Dynahi and bring that over. 2 months, it's going to be a close call.

I'm in. I will bring Gamma 2; Parasound D/AC 1600HD; KGSSHV; and CKKIII if nothing goes wrong. Headphones still need to be decided.

June July?   it's 30 days off

Acutally, I'm in UC too. My finals are in June, and I believe all quarter based UCs have their finals in June. So unless you are in UCB or UCM or UC Law, any date in July should work fine.   $15 fee is fine.

Well... it depends on age...   If you are talking about 10-year-olds, no, it will be a terrible idea with all those cables running on the ground and hanging off the tables. They are like traps, and if someone trips on them, well that would be very bad for the gear and for the person who...

That sounds great! Any rough guess where the location is? Is it set to be around downtown? Better to find a facility that has a parking structure near, because most downtown street parkings have 1~2hour limit during daytime.

damn it, I missed the deadline for the Stax systems.  Really want to try some stock stax systems, in fact, any stax system....

Definately in. Any date during summer should work just fine. If it's summer, I should be able to bring Parasound D/AC 1600HD+KGSSHV+SR-007MK1 and a small dynamic rig. All depends on how far it's from the LA proper. Willing to pay a reasonable admission fee or make a small donation.

That both surprising and disappointing! I was always wondering how stax managed to cram all those circuits into such small enclosures.. now it's all clear..

Quote: This is new to me. Thanks for the info. I assumed that they all would have some form of regulated PSU like most comercial/DIY ones, since they are charging quite a bit for them.   still, something like 001 is much more suitable for portable use.

you need clean and regulated PSU for the amp, otherwise it will most likely sound like crap. those multi purpose battery pack meant for charging batteries have quite a bit of noise making them not of best choice for audio. best way to go is find yourself a 120V battery pack and plug the...

Quote:   EDIT. Misread the entire original post. Stupidity on my side.   I thought he was saying that distortion happens at different volume level. :facepalm

Quote:   I know that higher input voltage will just push the amp to higher distortion faster. but shouldn't the distortion of XLR be of the same maginitude of RCA, if the final output dB on the headphone are set to the same level? (Not particularly familiar with how tubes work. I'm...

Quote: XLR basically just gives the amp with lower gain more headroom and brings the benefit of higher slew rate. Other than these two... I don't think there is any more potential benefits worth mentioning.   I'm no expert, but yeah XLR do deliver twice the voltage (louder.) The...

Quote: I believe it is entirely acceptable (even welcomed) to disuss cable (in this thread) in your case, because replacing the cable was not optional, but the previous post isn't suggesting anything close to this.
