You can update firmware connecting the unit to a computer (via included cable) that has downloaded the file. Windows and Mac.
The updates add features like Azimuth tuning, and fine channel balance and fixes small bugs if any. Beta testing is optional.
arcticdeth, if you're not learning, what are you going? Forgetting.. LOL

That's what my OLD journeyman use to tell me.. He was pretty much right too. He told me every thing has a time, then would laugh, and say "now keep it short". 

Everything has updates, from OBD2 on all equipment, cars, machinery, or just about anything with an accumulating carbon foot print and requires power to work, or produce work..

I been updating equipment computers sense the Lean Burn Chryslers in 76-79. I was part of the Chryslers field R&D in regards to pre OBDI it was OLD tech. BUT tight code.. really tight..

Digital is 1 and 0 there is always a way to Fuc$ with it .. trust me..

I have compiled some cowboy code for sure.. Even hydraulics are completely interfaced with human touch to CLAW out 5 yards of earth and load it in a tractor/truck. All with the touch of a joystick and NEVER see the truck giggle, it was so smooth, just squat as the weight was added..

This little Puffin, is just my cup of tea.. As techie as I want it to be... OR as simple as I want it to be. Full Flex Phono/Tape preamp.

Truly in the low dollars spent for high returns category.. I can't find a bad review..

Regards

I listened to a record last night that was really noisy and thought I'd throw it on my VPI to see if it sounded as bad there.  To my surprise, it was really quiet and right away I started thinking about what could be wrong with my other table, which has a cartridge with a brand new stylus on it. 

It took me a minute to realize that I had turned the "magic" function on in the Puffin and forgot to turn it off, and that it actually works!
