The Stax thread (New) - Page 506

Alex from APureSound mentioned he was working on an electrostatic headphone cable. You might want to shoot him a PM or email

Grazie Covenant, will do!

Somebody do a noob a favor and gimme 50 words on why I should spring 4+ large to replace my 303/323ii rig ... before Yama's (or TTVJ?) quits taking orders for the day ...

w/ the OII/tube, that is ...

TIA,

If it makes you feel any better, wrap your cable in aluminium foil.

I'll do it in one word. Don't. There's so much more to the stax world than just the starter SR-303 and the top of the line O2.

Again, a vastly more considered (and considerate) response than I had any right to expect. Apologies for my impatience, and great thanks, to Tachikoma and the list. My accelerating decrepitude requires acquiring the O2 before fully appreciating its development via full exposure to the earlier product lines. Cross your fingers that my appreciation for the O2 isn't consequently stunted. I greatly value all y'all's impressions previously reported here.

TIA,

yes, and also.

Thanks so much for that review. I owned the 650s for a long time, among several other phones, and I have heard in detail most notable dynamic phones in production as of a few years ago. Needless to say, I grew steadily dissatisfied with all of them, and all their problems.

In light of my current work, maybe I should start designing a field coil headphone? JayKay... really. don't hold your breath on this one!

There are some great dynamic phones out there, but now, I am on the long search for an electrostat (or two) that is worthy of building a killer DIY amp for. Maybe in a year, Ill have a system.

Yes, a basic comparo between the lambda pro and the 404 and the 303 would be very nice to read, but really, no worries on the time. Thanks so much for the efforts!

What's wrong with going straightly to the top? It only saves money

Nothing I would say.
I went straight from iPod and Grado SR80 to Electrocompaniet ECD1, SRM-007t and SR-007BL. Smartest move ever imo.

Thank you very much, you've been very kind and precise.

Did you buy it from PriceJapan? After how much time did it arrive?

Pot mod for SRD Energizer

So here i am swamped with piece of kit. My desk looks like a electronics graveyard. I have a ps1 (due for a psu mod) 2 srd7's, an srd 4, a fantastic nad 3020b amp and a zero dac (due for a new transformer), computer monitor, keyboard, mouse, dip chip puller, screwdrivers etc etc etc....

I want to tidy my system and put all the stuff onto a shelf above my desk out of the way but before i do i want to keep one of the srd'7 on the desk as my headphone output. Now being a lazy sod and not wanting to exert myself by standing up to adjust the volume would it be viable to swap out the earspeaker loudspeaker switch for a pot?

What im thinking is rather than on off, i could put in a stereo pot connected to the left and right connectors for the stax headphone out prior to the point where it changes voltage to the pro and normal connectors this way i can move everything where i want and just run some decent speaker cable from the nad to the srd?

What do you guys think? Is this viable and if so what type of pot would your recommend? With my current setup if i control attenuation via the Nad's pot or the Zero Dac Pot i cant put the volume above about 10 o'clock before it is just too loud to listen to.

This would allow me to clear my desk mostly and find a use for the front of the srd - i don't use speakers anymore so the switch is currently just an on off for me.

Thanks.

btw. i know this is more of a diy thing but due to the volts etc on electrostats i thought you guys would be more likely to have an idea.

Someone went a little nuts for an SR-3

You could put a pot instead of the switch but it makes no sense to attenuate after the signal has been amplified. A normal pot would never do and I don't know where you would find a high power log pot as it needs to be able to dissipate quite a lot of heat.

There is no voltage change for the Pro and Normal bias outputs as the bias is completely independent of the drive voltages generated in the transformers.

I figured there might be an issue with attentuating the volts after the tranformation from 580 to 240 volts on the bias

looks like i'll have to get out of my chair

Thanks Spritzer - the font of all electrostatic knowledge

SRM-727II. But it's the headphones not the amp.
In fact I don't feel any burn-in effect. If there is some it's minimal.
I'm waiting the 500hrs point (as the guy from STAX USA told me). The high-end is near.
