Elephas has posted great things about his Jade and ES-1 together.

My GES is good to go right away, but sounds better in under 30 minutes with music running.

[EDIT - immtbiker got his post in before me, but basically we said the same thing]

The Jade is no different from just about any other 'stat so the amp should be ready in a matter of seconds. With my DIY Egmont it was instantly after I flipped on the HV supply (I preheated the tubes for 30 seconds to make them last longer).

Hmmmm. So it appears something is wrong in my system. So how do I determine what? I only have one electrostatic amp and one electrostatic headphone. Any ideas besides buying another of one or the other?

Your best bet would be to borrow or buy an old Stax Lambda as they are easy to sell back at a minimal loss. That said I don't believe it's the phones causing this extremely slow turn on cycle as the only culprit could be an uncoated diaphragm but even uncoated mylar would have been fully charged up after 10 minutes. You also have an ES-1 which are notorious for being badly
"designed" and build quality is even worse.

About 10 minutes to warm up is about right, for the ES-1 as well as Aristaeus.

The ES-1 can be used right after power on, about 30 seconds, but I usually give it about 5 minutes before listening. It does seem to sound better after 30 minutes.

I did have problems dealing with SP and waited a long time after payment before receiving the ES-1. I'm still waiting for another amp, and I'm aware of potential design and build quality issues others have reported. But I think the ES-1 is the best-sounding amp I've heard, better than the Aristaeus, and much superior than my former KGSS or the few Stax amps I've heard. I do worry about it breaking down, which is probably likely if there are design issues, but I'll somehow deal with it when it happens, maybe sending it for a Spritzerfication.

I haven't used my Zana Deux and dynamic headphones for a few months, due to lack of interest. I know, that's a horrible thing to say, but I can't help it.

Also check your tubes. I've had experiences where a power tube couldn't bias right, or was unstable. Good tubes are easy to set bias and very steady. Some of the rare and expensive tubes do sound particularly good, and I can understand why they are expensive.

With the SRS-717 it takes about an hour to an hour and a half for the O2 and a little longer for the Jade. The process is exponential meaning that within 20 minutes things get pretty well and within 45 minutes you are almost there but then it takes another 45 min for the final 10% of the improvement. The first 20 minutes are recognized by people with no experience or knowledge of this phenomenon as I had friends ask me as they noticed the improvement occurring during the warm up period.

Return of the Jade

I was really sorry to see my Jade go. I shipped them today back to China.

Another victim of the economic crisis.
A few more of my friends in Greece and in the rest of the world are now without a job.

Mr Fang,

I shipped the Jade registered air mail because EMS would not accept insuring goods going to China.
The maximum I could insure them for with registered air mail which I did was 891 Euros. Estimated time of arrival was stated to be 7 to 10 working days. There is no tracking. Registered Air mail with insurance was 48 Euros.

EMS was 122 Euros but they would not insure them going to China. Apparently EMS is half Greek and half local (China) and the Greek side is peculiar (ie f..... up).

UPS and Fed-EX were 200+ Euros and I would have to pay import duty and VAT if I was to insure them based on the insurance value that was declared when shipped as sample which was 730$. In other words an additional 25% of 730 which is another 200$. Or a total of 350 Euros.

For a little more I could have bought a round trip ticket to China and come visit with Mr. He.

I added a half inch Styrofoam plate to the bottom and another one to the top of the box inside the cartoon to make them immune to handling.

Thank you for your continued support. I do feel sorry for the return. There was nothing wrong with my Jades and the sound was superb.

Received the Jade in the mail today, listening to them on my backup SRM1/MKII at my in-laws. I must say they are a lot lighter than they look. Sounds good.... different from the O2. Can't wait to plug them into the BH when I get home this weekend.

I think I passed up the end of my 30 day return period Monday - keeping the Jade. Meanwhile I am waiting for a pair of K1000 to ship to me soon, so I can ship them my O2 Mk1...

Hey bdh, is you ES-1 new or did you get it used? I only ask since I've owned some tube amps that take waaay longer to sound good until the cap's and such are fully burned in.
If not, are the tubes new? That could extend the warm up time too. I think half an hour is a pretty common amount of time for most tube designs to sound their best though.
Unless your ES-1 is still under warranty, I'd take it to someone local to do any repairs on it. Of course if Mikhail could give you a decent turnaround time, that would be great, but there are lots of guys who could repair any design. I do as much repair and mods that I can, but when I get stumped, I have a local guy that does any repairs I want very cheaply and usually in a couple of weeks. He's also a highly respected designer/builder and I'd have no problem taking him the most complex gear to repair. I met him through my local audio dealer.

You should give us an idea of what you're hearing that makes you think that it needs repair. Maybe some could put you on the right track.

Isn't that an oxymoron?

Sad to say, but true enough Aaron.
I can't help but think that if things continue the way they have been for SP owners, it would be a good idea to develop a few good repair/mod people to do the service on this gear in a few areas. After all companies like Audio Research, Audio Note etc. have their warranty work done by local shops in many cases.

It's used.
I switched the tubes in the power supply, and it's a little bit better. It's hard to compare what I'm hearing and what others are. My experience could be like kintsaki's, and it's just that the last 10% is as important to me as the first 90%.
However, I solved most of my problem by getting a timer that turns the amp on a couple of hours before I wake up.

My next problem though is even when fully charged, the sound on some songs with very complex passages with loud strong bass, the bass breaks up \ distorts some. The Jades probably only have 25 hours on them so far, so I'm not sure if the cause is that they need the 200 hour break-in, or if it's the tubes, or the amp. Of the EL34 tubes I have, the ones I like best are the Groove Tube EL34M (the xf2 re-issue), however the ones I have only have a hardness of 4 (out of ten). I'm also using a Sylvania 6sn7gta and a Sylvania 6bl7 as input and middle tubes.

And I do have a local friend that repairs tube amps, so hopefully I'm covered there if something breaks.
