Good to see that this thread is still around after all these years. I still love my XS. It's a gift during my student's days and it still brings back some good memories. I suggest trying the cap change. It gives the greatest benefit I would say. And maybe also the output resistor to a carbon...

Yes exactly, and I suspected that the e7 actually went into a "lock"(on-off mode) mode when connected to the E9.   Could there be some power issues on the circuitry of the E9 as it will automatically charged the E7.   I also noted that the E9 is not very well grounded, quite a bit of...

Well, I am still around. My xiangsheng have been restore to its original state except for all the changed parts. Was working in China in the last 2years plus and managed to locate the manufacturer and restore it back to its original look with the tube in front.   Since then I have left it at...

I have had the same problem too.   When combined the music plays for about 25 secs or so before "lock" flash on the E7 and the foobar gets hang.   Anyone knows why this is happening? 

Actually, I did try it before I thought it was quite amazing, but I need some opinions just to make sure that its not a placebo effect. However it have been a while since I last heard it, and after the relocation all my equipments are all scatter around.   Anyone who tried the cardas with...

Anyone tried grado with cardas? Any good?

Hi guys, I have gotten a pair of these, but I don't see much info about this 2 pair of phones, except for the usual normal portapro. I believe they should be the same except for the colours. Since when were these made available, and are they still in production? Will I be able to get...

My humming problem seems to be back and tracng it seems to show that the tubes are not the culprit. Could it be the tranny? Anyone any advice?

Anyway I have managed to solve the problem. It was a faulty tube, the 5670. I am replacingit with a tungsol 2c51 which works very well.

I have changed in the musicaps however now I am experiencing some hums on the left side when the volume knob is at zero. As I turn up the volume knob, the hum gets louder even when nothing is playing. Any help anyone?

Well I am still here and I am thinking of suing the head amp as a preamp. have gotten some holand musicaps for the job, let's just see when's the time to do so.

haven' been around for quite a while and you are still as amazing. any idea where i can get more info about the mentioned DM944?

It bring a lot of joy to me reading this thread. Well you will be so surprise that in China it doesn't work like what you guys would think of it to be. I am located in China for work for at least half a year now, while my search for cheap audio stuff never stop. There are fakes for stuff...

I purchase the wires ready made for this job, I use the cable on the grado SR80 and they sounded really good, hence proceed to use this on the shures. So what i do is just opening up the shell, desolder the 2 points and then connect it back, test it it works then put the shell back. Before...

You can open up the driver from the side shell, and there is only 2 points on the driver. You will need a DMM to test which is which. I was selling this pair of phones a few weeks ago, but was met with some disastrous matter. I may be giving these phones away for a token and a review on...

No. In fact, for those who find the E2s flat, dull or boring should try to recable them with silver wires. They simply change my opinion of them after I recabled them with some silver wires.

Check the solder points to and out of the volume pot and the wires to the RCA

I have gone thru 2 -3 rounds of modding the SR80 and found that the most impact came from the change in cable. Then getting teh right cable is another thing. While many says that the grills have little or impact, i hear a difference in the change of grills from the original. My friend who...

edit

DEfinitely a good buy and you will have no regrets with this amp, I got one and it replace a couple of my amps. I am also curious about the opa627

yeah sure looking forward, learning a new thing is always fun and satisfying when you manage to complete it.

I apply small amout of super glue to it, which might not be a good thing if you are unsure abt the cables. The only thing is that there is gap where the wires enter the phones. my cables are thinner and do not have the strain relieve

I thought I should have an update to the progress of the earphones, and here they are recabled with some silver cables and they sounded fantastic right off the soldering iron.
