Reading this thread was what convinced me to buy them as there doesn't seem to be many people that have had any majer issues with them plus the fact I'm not good with change so when I find something I like I tend to stick with it. On that note I don't see any reason why what I have now won't...

I'm a little late to the party with these but as they say better late than never. It actually took me a couple of months to decide on weather to buy them or not as I've been happy with my shp9500 and grado sr60e but I think I got a good deal from Amazon at £111 for the x2hr. They've surprised me...

It's like anything in audio some do and some don't. The original chip is already quite good but you can do better. I tried the BB op amp's and preferred the original but I came across the MUSES 8920 j fet and that is a noticeable improvement and didn't break the bank.

I ordered mine from eBay but was lucky I found a couple in the UK. I'm pretty sure Amazon have them as well.

All the way with a socket saver I'd recommend replacing the power cable as well if possible. I use Russ Andrews power cords in my headphone system. I know some people say they make no difference but I think if you can use a better quality cable it can't hurt.

It was a inexpensive bakelite gold pin one. It went in easy but I'm not sure how easy it will be to take out if I ever need to remove it but it definitely helps to cool it down lifting the back tube out of the case.

Just thought I would share som pic's of my Helot with tube raiser's under the 12bh7. Hoping it will help with cooling a little and I think it also looks the part. Also tube's I have so far. The JJ tube's came in my amp. I'm currently using the EH 12bh7 with a Sylvania 12au7 black plate square...

I've been reading that the one's made in England are very good but I can't find much on the foreign versions and there seems to be a big difference in price between the two versions. The 12au7 is reasonable but the 12bh7 made in England gets quite expensive. Martin

Thank you for your reply. And thank you for confirming that the helot will drive the hifiman as it was something I was thinking about. Martin

Hi everyone I just thought I would share my thoughts on the sr60e I bought not to long ago. As I said I only bought them because they were brand new and half price and I was curious. I'm so glad I bought them because these things absolutely fly. I was listening to them today and it brought back...

Have you used any of the Brimar tubes they seem to have a good reputation and the 12 au7 look's to be a reasonable price.

Thank you for your advice I think I will give them a try. I don't think they are that uncomfortable they are definitely the most comfortable on ear I have had and strangely it's only one ear that gets a bit painful after a while. Like you say I won't really know untill I try them Thank you very...

I don't get any noise as far as I can tell. Thank you for your reply. Martin
