Official NYC Spring 2011 Meet March 19th - Page 3  

I usually have lab on saturday, but I assure you I shall make every effort to attend!

I'm there!

Count me in.  Looking forward to seeing everyone again.  I hope you are doing well in the snowy cold Winter.  Scottsmrnyc

I like your ideas, sir, and would like to subscribe to your newsletter.

I broke my foot & arm this past weekend. Will be laid up for at least six weeks, which is right about the meet date. I'll see how I am the week before.

Sorry to hear this Jimmy.  Get well soon.

I fell from my lower roof cleaning my gutters once and broke my foot.  I can sympathize.

I am thinking of holding a $69 amp challenge.

The objective is simple: to build a headphone amp for $69. Naturally we will have some informal judging, but the biggest thing is for you to try something new at a minimal price.

Some rules

The amp must be safe. No mains coupled circuits, no exposed wires, no excessive offset voltage at the output (15mV MAX!) and the chassis must be grounded.

The amp must be wall powered. 

The amp may not be an obvious variant of a cmoy. This is about trying something NEW to you. Tubes, solid state, hybrids anything you can think of that does not use obvious opamps is fair game but try to find a new circuit.

The amp must drive HD650 or 800 and the Grado SR060 to at least 100dB. Bet you can guess what headphones will be used to test.

You must provide a Schematic and BOM (with prices) at the meet

The chassis must come from Ikea, the container store, or some similar source. The price of the container is not included in the $69 price.

Amps will be judged on sound quality compared to the other amps in the competition, circuit "unequeness", and the creativity shown in the selection of the chassis. At the moment there is no prize aside from pride in building and ownership.

Just wondering... what is the general time range for these meets? I need to figure out how I am going to do that day... Or if I need to skip lab for a day...

Hmm!  I'm going to see if I can sneak off to this one!  I have a few goodies to donate to the auction too, like the original Darth Beyers (unfortunately with a bad connection out one earpiece, probably just a wiring thing) and the AKG K81DJs I won from the first international Head-fi meet (again, busted wire connection, probably a good DIY for a cable guy).  Come to think of it, my replacement K81DJs are also slowly going on the fritz depending on which way the wind blows on the cable at any given time, so maybe I'll donate those too and hunt for some new portable closed cans at the meet for under $100?   Hmm!  And I have to eat some of those legendary brownies again!

Wow, it's been ages since the last time I've seen you at a NY meet.  Very cool.

Edit: had to cancel my flight, so not coming after all. Forgot about a conflict with the date.

I am so pumped for this, as I just got into building amps, makes me want to hold off on building this other cmoybb I have waiting under my desk. Need to find me a good case for this guy. Who knows, maybe I will get restless build this one and make something else to submit to the contest.

Also, @Jahn, I wish the meetup was sooner as I am about to pull the trigger on some AKG K81s :S

Though, by the time the meetup happens I should have a nicely burned in pair of Black on black K518s(hopefully).

Can't wait.
