Anybody from the US planning on attending?  It turns out I'll be in Tokyo this weekend, so maybe I will...   Pete
I posted a little more info about the Sangaku on the Apex HiFi website at http://www.apexhifi.com/Sangaku.htm.   It's a pretty cool little amp.  It has the sonic characteristics of a directly-heated triode - which in fact the NuTube is - and the drive capability of a low-impedance solid-state amp.  I've been listening to it with K1000's, and it sounds great to me!   Here is what a NuTube looks like:     Pete
On the top is the main power transformer (~180W) and first filter choke... inside are two more filter chokes, one for each channel, plus another power transformer for housekeeping and the 6SN7 DC heater voltage. With a low-mu triode as the output, it's important to have very low power supply ripple, or you'd hear hum in sensitive headphones. Pete
Sorry, it seems beer has delayed the announcement. Stay tuned 😊
We have selected a winner! We'll announce it this evening at about 6:00 at the beer social at CanJam.
 Simply, because it didn't fit!  I would have preferred the 1/4" jack... There's a lot of stuff crammed into this little package. Pete
Wow, there are a lot of good suggested names here.  It will be a challenge to pick one...   Pete
FWIW... you can also set the LEDs to a mode in which only one LED is lit, instead of all the ones below.  "Dot mode" vs. "Bar mode".   The brightness is also adjustable. These settings are programmed in a setup mode, and are stored in internal flash memory so they remain unless you change them again. Pete
 I'd suggest using a 6528.  The only downside is that they get really hot, and sometimes make some funny mechanical noises.  A 5998 would be an option as well. The IEM position might be attenuated too much for Grados, depending on how loud you listen, or it might be OK. Input impedance is 50k, yes. Pete
 I understand.  It IS expensive.  Hopefully you believe me when I say that the selling price is based on the cost to build - it is really not the same as the Little Dot amp with an enormous profit margin. The unfortunate reality is that you just cannot build something in the US at anywhere near the cost (using locally sourced parts) in China.  Fabricating the metal chassis for this amp costs me almost the same as what the entire Little Dot amp costs you to buy! Chinese...
