Headphone Amp Inventory
I build DIY amps for fun. To date i have built:

A cmoy, with onboard regulator and 18v wallwart. opa2134. Gifted to my father, then brought back for repairs and upgrades. still on the workbench. really oughta fix it.

A47 (2x opa2107), wall-powered 18-0-18 dual regulated power supply, modified linkwitz crossfeed, and all in a mint tin.

AMB Labs M3, with opa627/637 combo.

Sijosae iHybrid Nano 6111WA + jrc4556 (I think) - teeny tiny mint tin tube/chip hybrid. Gifted to my father.

Sijosae's "Simple Class A-B" v.1 headphone amp, 12v wall powered, opa2111 + bc550/560, gifted out to my brother Andrew. He drives eensy 'puter speakers with it, and it sounds great. Go figure.

Millet Hybrid RevMH + diamond buffer, with toshiba power transistors and Silmic II output caps. Mounted in a cigar box.

SOHA v.1, hand-made on perfboard. GE 5963 + lm4562. In dire need of a beefier output stage, but it drives 600-ohm AKGs beautifully.

Millet Hybrid Maxed, mosfet output, Muse KZ output caps. Still need to do the case work.

Mini3 v.2, high performance variation. Highly recommended if you can do SMT work.

CK2III - Sanyo output transistors. Highly recommended for DIYers who want to move up from the CMOY and do something worthwhile. Very musical amp that doesn't cost much to build.

Bijou all-tube streamlined futterman OTL. 6n1p-ev + 6n6p. An excellent tube amp, but expect to spend at least $200 building it. $50 of that just on the power transformer - a harrowing experience for a cheap person!

I also own a GoVibe v.5 basic, which I'll probably sell after i drill the end panels for the mini3. It's good, but not as good as the mini3.

Exstata prototypes, solid state and hybrid.

If stax stuff counts here, i have an SRD-4, two SRD-7's, and an SRD-X.
