If you want a tube and keep it portable, then I'd go with something like the 6111 tube "subminiature" type (like used in the ALO Continental) - and I like

how they last pretty much forever.   I'm not sure how easily it would fit, but worth looking into.  I also think hi/low gain is important.

 

If you want E88CC (6922), then it will no longer be portable.

Vinnie, what about the tubes in my TU-05, 3S4 or 1T4/1U4? They were designed for Battery radio's, especially military and though not as tiny as the 6111 they are still on the small side, generate no heat and there are plenty around for tube rolling if one wanted. In the socket they are about 4.5cm in length width about 1.5cm. Very long lasting and robust as most as I say were designed to handle military radio abuse!

When I look at the amp cards on the 901, I tell myself it possible to have great sounding compact amp boards...I think?

45mm x 15mm is still large for a tube(s) inside of a portable dap.  If the dap gets too big, then you might as well just velcro them together and connect with a cable or put them in a travel bag (like the TU-05 + AK120 in a custom fit travel bag).  

 

I was talking about extending the thickness (depth) of the AK120 player by 10 to 15mm, but keeping the footprint and still keeping it very portable.  I don't even know if it is possible to fit it with a larger battery that has enough life to support this idea.

With the ak120/rw-s/b you can use an external usb battery to charge it. I usually travel with this which has a build in micro usb cable and a lightning for my iphone

Good thing is you don't need a huge brick like the hifiman 901 players. With this option, 6 hours is more than enough for me with my ak120-b

A quick look of the AK240…

I'm still waiting on my AK120 in the mail, so this only has a passing interest to me.

I think for most, 6 hours would be enough if the sound was top tier.  Of course > 6 hours is a plus.

And top tier it is Vinnie!!!

Love my rw120b with my rsa f-35 and my pico slim feeding my jh16s (and soon the Roxannes).

Thx Vinnie and guys, I decided to drop 1 battery. I will mod and enjoy 1 piece dap + amp for now till Vinnie get his up.

Maybe would have another breakthrough after dismantle my AK120 board today;). Hopefully reduce another 3mm. 25mm would be sweet with brass casing and gold anodize? smily_headphones1.gif

I think this word is a bit optimistic (I am in the same case :) )

Just got my new AK120 today after owning an AK100 for a couple of months and a Colorfly C4 Pro before that. It's going through the 200 hour burn in process now, and when that's done, I hope to report back on my feelings between the AK100 and AK120.

 

The primary use for me is as a server for my main system and a USB DAC for my MacBook Air. I had some issues getting the USB DAC on the AK100 working, but the AK120 was a cinch. Sounds good with my ESW9As ...

I was just curious about the idea.  But to design in an amp and casing would take time and $$$ - both of

which are in short supply these days.

 

So I was just curious about the thought of it.  Making anything happen is another thing, but if there is an

interest (seems good so far), then I'll see what I can do).

 

Thanks!

 

Vinnie

 

Maybe I can be your guinea pig ;)...
