No plans for mic input and too far down the track to change now. The unit is fully encased - so tubes are visible but enclosed in the housing

Nice , would it work with a mic'd headset

 

[Brooko]

Mic won't work (other amps I've owned are similar) - but I can check re sound once I get the prototype back. 

 

[mochill]

Thanks for your time my friend , will it be able to power 320ohm earbuds for instance

 

[Brooko]

That's a really good question.  What is their sensitivity?  I'm hoping to have the updated prototype back with me next week - and then I can run some more specific tests.

What will I expect to pay for a low impedance, low output IEM version with volume control, in black, delivered to Shanghai?

 

[Brooko]

KS price is NZD 179 for a single, or $299 for two.
 
So that's USD 135 for one, and 112 each if you buy two.
 
I'm not sure about the freight side of things.  I'll check.

 

[CJG888]

USD135?

Please reserve one for me. IEM version, i.e. low gain, low impedance, quiet as the grave (or as the vacuum of space)...

I originally bought the TU-HP01 for this purpose, and was greeted with HISSSSSSSSS!

One other great thing about this amp: it should stack nicely with my HM-601LE...

You can't reserve it - you have to commit on KS.  Go to the website (https://www.kickstarter.com/projects/970055861/hybrid-valve-headphone-amplifier), click to commit to the reward you want (you'll have to join) - and if it's successfully funded in another 12 days, the money is deducted from your account, and it's delivered sometime in July.
 
I checked with Martin - and the freight cost is $18 NZD (about USD 14.00) delivered world-wide.
 
They're now at 87% funding with 12 days to go - so it'll definitely reach its funding goal

I want to back this on Kickstarter. How can I make sure I get a low impedance model with volume control? There don't seem to be any options available...

There is now only going to eb one model, switchable gain, and with a volume pot.  If he does do a low and high impedance (separate) - you'll choose just before he ships.  Don't worry about it - the process is pretty easy.

 

[CJG888]

Backed!

Thanks.

For sensitivity I don't know but I only know it says 105db at 1khz

 

[Brooko]

Yep - that's what I was after. When I get it back, if it drives my HD600, it should also handle yours ok.
