Nice job on the amps! Good job on the casing... IEC and switch holes, etc. look good (as in pro). Are the RCAs the ones from Australia?

fallenangel,
You have the exact amps which I would love to hear some opinions about, when compared to each other. Any comments about their sound quality and which you prefer?

Thanks.

I can't speak for Fallen Angel, but keep in mind that's a MOSFET MAX. It's sort of like pairing a tube stage with a Szekeres (MOSFET buffer with no feedback). The BJT version, on the other hand is sort of like pairing a tube stage with a PPA. A strong effect in either case, depending on preference, but very different.

You have to be specific when making comparisons with the MAX.

Default just had to share my new toy

I know this doesn't really qualify as new DIY but I am just so chuffed with this little beast and as I never posted images of the EHHA in the background I figured I may be excused by some of you more hard core law abiders.

It is a Samsung UMPC and is just so much fun to play with. I got it for a far more boring reason but it is going to feed my habit in many more ways :-). To keep this semi DIY oriented - the EHHA is runeight's Embedded Hybrid Headphone Amplifier, MOSFET output powered by AMB's simply beautiful S22. It will be available to all shortly and all I will say at this time is that it is Class A and happily shares the shelf alongside runeight's pride, the Bijou..dB

I have tried this using lead-free solder and it just doesn't work. I was using FR4 perfboards and ended up having to use the component leads.

You really have some mad perfboard skills I wish I could do something half that good.

Mine always look creepy so I am glad that they are in enclosures

thanks guys, that was all kind words.

If you're interested, all the bridges are done with a kester 245 and a Hakko 936 at 310 Celcius setting.

I'd like to try some real manly professional PCBs much later. Perfboards are realllly fun to work with but they just don't give as much performance compared to PCBs (sadly, sadly).

That is really nice work... I don't think I could do that. You just bridge between the pads with solder? Handy skill to have for protos.
