Yes, it is 0.75 mm. You could use any KZ cables with "a pin".

No, Secret Garden and Secret Garden 3 are the TFZ's flagships .

8(h)x5(days)x52(weeks per year)x5(years)=10400 hours. So I think your tube is dead. Firstly just try to buy a replacement tube.

Yes, it is correct. I'm using ALSA plugin and IEC958 (S/PDIF) Digital Audio Output. Does the tube working correctly in the your Aune?

I'm running Fedora and everything is ok. So I think there are no any constraints to run it under Ubuntu. You need to select DigiHug USB Spdiff out. DeadBeef is a good player to do so.

Issue with buttons was fixed in the new versions. Interface is not so user friendly. Only stock software.

No one? I would like to know about this comparison too.

Hi, Gustard H12(H10) will be a good option in this way if you have no budget constraints. Or you can try any card with XMOS chip as usb receiver. I have no problems with XMOS cards on Fedora at all. Good luck!

Let manage it by following way - what is your goal? What do you want to do with such card? Just for example: www.ebay.com/itm/251550012954 www.ebay.com/itm/232043414419

Hi, any card with XMOS chip will work fine.

As combo as DAC/amp for sure. T1 have good DAC part (musical and enjoyable with good tube). I have Sabre DAC (NFB-11 from Audio- GD). I think that it have same level as GreekOut advised by you. I still prefer Aune T1 as DAC only. I will show one photo for you: Fortunately I have good tubes...

You are using pulseaudio in this case, not just ALSA. You may try deadbeaf player. It can play directly to ALSA devices.

You have a good source of tubes locally http://www.langrex.co.uk/. It is not cheapest one but have really good tubes. Choosing of tube depends on your headphones and taste. So you could ask peoples with same headphones and musical taste or just try various tubes. Just for example: First of...

It's wise choice. Have a fun!

Do you need only headphone amplifier for this budget or DAC also? Do you have experience with soldering?

Please don't consider Aune T1 as headphone amplifier. Aune T1 is a good DAC but it's amplifier part just for "checking mark". Aune T1 amplifier board costs 4$ as spare part (you can find out this information in Aune T1 thread). Aune T1 is pretty good as DAC for it's cost. I don't think that...

Magnifying glasses like this one: l http://www.ebay.com/itm/152028347481 are really helpful in such type of soldering. Good luck!:)

Mullard (from my experience) will. Blackburn or Mitchem plant (Bxxx and Rxxx codes). Older is better. http://www.audiotubes.com/mullcode.htm

Why you are looking for Philips if you have Mullards and Brimars locally?:) It's both very good sounding tubes.

Finding tubes in UK is easy - http://www.langrex.co.uk/. A little bit princely but there are good tubes.

Mostly yes, but you could find out good deals. Once I bought NOS, unopened Tele fo 20EUR.:)

Telefunken, Berlin plant tubes is the best choice for you. Older is better. Telefunken tubes have 3D holographic sound and really amazing on female vocals. Telefunken tubes have a problems on large orchestras and metal music in bass area so if you away of such type of music it is a best choice...

It depends on music which you prefer.

I think VirtualBox + Windows Guest is only possibility to do it.
