Best SQ Portable DIY amp?

[jamess71]

Now that the nice weather is here, finally. I would like to have a portable to bring out in the yard. What is the best SQ DIY portable out there?

Thanks

I don't know if I would call the Lisa III portable, it's pretty damn big.

so my response would be the Mini3

Yeah, Mini3 is pretty sweet! I only wish I had it powering something better than KSC75s... Maybe PX100s?

I'd say there are a many designs I like more than Mini^3, but it is a nice amp.

Lisa III is pretty awesome if you can DIY it.

I personally like the Pimeta much more as I like buffered designs more than opamps alone and of course if you can find a PPAS board, that'll be one of the best amps, my personal favorite amp by a mile

If you're not scared for perfboard, a 3-channel Sijosae Class-AB is very sweet. Modify it a little to include rail isolation JFETs for the opamps and you've got something similar to a PPAS with Diamond Buffers I really liked the Class-AB, it's cheap to build, sounds fantastic, great battery life, it's just an awesome amp. The 3-channel version is even better.

You can of course run a JISBOS off AAA for awesome results, as long as you don't need gain.

FallenAngel The PPAS board you mention with the Pimeta. Are you talking about the PPA Battery board or the PPA v2 Amplifier Board? Looks like all the Pimeta / PPA and companion boards are available at tangents shop, Tangent’s Parts Shop. Hmmmmm which one? So these definatey a step up from a mini? thanks again everybody.

The PPAS was a surface mount board design based off the PPA circuit. IIRC, Tangent didn't make any boards, but someone else did one run of them. There's a pic of one here: http://www.head-fi.org/forums/2588717-post172.html

The PPAS looks very interesting
I wonder if anyone here can build it?
