I tot it caused by tm "nut" too...

btw, I tested the T-amp with 12V Li-Ion battery, the SQ can't compare to SMPS.
SMPS give me better soundstage smile.gif

Oh really? I have read somewhere, this particular guy prefers SLA.. so does Red Wine Audio..
I did tried SMPS.. excellent but loose out some 'details' to linear PSU as posted earlier. I personally have NOT tried my DIN55 battery..
Honestly I do not know what to expect. No doubt the battery has A LOT of current reserves but as we all know, the T-Amp draws very little current!
*
I didn't hear long enough for detail but obviously the soundstage not as wide as SMPS so I stop for further test.
Unless I need portable amp or else I will stick to SMPS smile.gif

for those installing T-amp into casing, please pay note to this type of speaker terminals (refer to pic),
they are not suitable for metal casing coz it didn't c/w insulation washer like those RCA input connectors.
All the outputs of T-amp will short to casing (ground) when we tighten it !!! sweat.gif

jazzy, my SMPS is 12V 4A smile.gif
With sufficient power caps >10,000uF I believe 2A will be good enough.

Mine with 8200uF even blasting till clipping the current draw from SMPS hardly exceed 1.5A! tongue.gif

ongbs,
Great and compact looking! I like it!  thumbup.gif
BTW, Where did you get those inductors? Mean looking stuffs! tongue.gif

LED no light also ok.. it’s the sound that counts!  laugh.gif

I got it from a shop tongue.gif
Just back home...no chance to test yet.

So far tested bookshelf (BS) speakers, more stable/better sound imaging.
Max current draw only 1000mA for BS with added extra one more unit of 8200uF power cap.
But power ON current draw went up close to 2000mA coz need to charge up 2 big caps tongue.gif
