I guess the Tripath/Sonic Impact is the new gainclone
Precisely. I think the 41Hz AMP3 kits will take off once everyone gets over soldering surface mount components! I too think the SI PCB can be improved, maybe SI will change the layout in a future realease. Until then, I ordered two AMP3 kits to work on after somehow frying one of my SI's (can't biamp with only one amp). If the sonics are as good I'll be more than happy with the results.

Sounds like fun.. Please post your results when you finish up.. I've decided to go back and actually finish my 20-some-odd gainclone variants before diving into surface mount fun.. But I do have another SI to finish up at some point!

My guess is that we are just seeing the birth of this thing...

I looked at the 41mz site a couple of months ago and then emailed them. I suggested that a kit with a lot of SMD soldering would not go too far. I thought that what we needed was a nice DIY board with heavy tracings, all of the signal path parts as through-hole type, and with the chip and SMD parts presoldered. Next someone should follow with a really well engineered amp for the non-DIYers: a "ground up" engineered board with battery management and the ability to keep the board always powered on. My modded SI takes 20 minutes to get frisky and 30 minutes to bloom. It is actually very much like a tube amp in the way it blooms. I am looking into adding a wall-wart 12v supply and a different switching scheme so that my board will be on even while the SLA charges.

My two cents... discounted for inflation.

Paul

Ahhh.. dont let a little SMT scare you. You might need some extra tools, a good magnifier or even a used microscope, and practice longer, but you can do most anything at home.

I'm struggeling with an AMP3 rigth now - **** those smd components are small :-)

I think I have got the hang of it - it's tricky but not impossible if patient.
