HI: You can take the t/a off the list. I have owned one and fix-up eats it up big time. The fix-up mini 9 volt with a gain of 5 db does anyway. I have ordered the super mini with a gain of 10 db and will get it in a few days.

why not the META42 too?

The Porta Corda II must be the most flexible PHA(portable headphone amp(amplifier)).

Hi,
All I can say is that my supermini is on par with Headroom Total Airhead. I really like mine, now I have to send it in to get it supercharge with Mini-like sound.

Oops. Can the META's be built in that size case? For some reason I thought they were larger.

I don't have it in front of me right now, but it's a tad bit longer than an AirHead. You can see a picture of it in an AirBag here:

The case is a Serpac, which comes in translucent blue, green, red or grey. It's 2.75" x 4.94" x .94". Its a tight fit for the META42 board and the I/O connections, and the pot has to be handwired. It is a bit longer than the Airheads or Porta-Corda. I made two similar amps that were a bit smaller and fit into my jogging case better, but they had to be done on a protoboard as the META42 board was too large to fit. One of them is in a Altoids tin.

Here's a picture for size comparison of MacDEF's amp and an Altoid version using the perfboard.

Depends on the headphones...

look at my 'signature'... its not as universal as it may seem that one amp is better than another... its all about system matching
