So tube mentioned are a step "up". What type sound signature changes would one expect to hear?

What about this? 6SN7GTA General Electric / 1950's $79.95 Price is for a single tube with standard testing. QTY: Free Shipping Over $99* NOS-6SN7GTA-GE

Its stock. Pretty new. Liking it though. Just figured maybe there was a basic tube upgrade. I could spend more if needed. What tube sizes should I be looking at?

Depends I guess. $200?

SALE PENDING Set of Ether Flow Open 1.1 headphone. Like new, mild use. All original packaging. Cable is XLR. $650 plus shipping. Thanks for looking, John

What's a good very available set of tubes for my DarkVoice. Have HD800S that I use with the amp. So I guess good bass character would be the focus. But I am not looking for an in depth search, just an off the shelf improvement - if possible.

Wondering which headphone people would buy that has a little thump but retains audio quality in the $3-4 ,000 range. Should be a good all-a-rounder. Right now I am thinking Meze Empyrean or LCD-4z. Any assistance and experience would be greatly appreciated. Thanks, john

Its 4.4 mm, I need 2.5mm. Coud get an adapter, seems like a inelegant solution.

I will check the others out as well. Thanks.

Wow. These things are amazing. Great clarity and superbly comfortable. Thank you again.

thanks

Thank you for the info. What tips are you using for a good seal? I have had my EX1000 for a long time and am revisiting to "refreshen" for lack of a better term. As with most earbuds, seal is important and I have several generic tips I have been messing with, wresting really. Don't want...

I know it is likely buried in here somewhere, but, where can a get a good set of balanced cables for the EX1000? THX john
