Cyber Monday – O2 Front Panels!

It’s doubtful I can convey anything more worthwhile than the pictures, so here’s this week’s big news:

Looks amazing, doesn’t it? Nick had a difficult time stepping away from the 3D model:

Our JDS Labs branded O2 front panels and fully assembled O2’s are available now for preorder.

c421: Quality Inspection 3

Continuing from our last update, the third batch of c421 cases arrived last week. To our great dismay, the manufacturer damaged our $1500 custom die (a tool to make the cases), so batch #3 turned out far worse than the first two batches. Instead of scratches, batch #3 pieces weren’t even the correct shape.

We’re moving case production to a high precision aluminum manufacturer. These guys understand the perfection we’re seeking and will ship nothing less than excellent. Since they’re starting from scratch, it will be February before final c421 cases are ready.

All c421 preorders will be shipped this week in batch #2 cases. You will be able to request a final case for free in February. Batch #2 cases aren’t terrible; they’re simply not up to our standards. Keep watching for more updates…

Side note: We had no trouble with c421 front panels. O2 panel production really will be done by January! We’ll post a “lessons learned” story when this mess is finished.

O2 Boards, c421 Reviewed

It’s time for a few short updates. First, we’re helping out with NwAvGuy’s do-it-yourself O2 project. Bare O2 circuit boards are in stock:

The O2 has created a stir in’s do-it-yourself community. After posting one too many “objective” (or possibly stubborn) comments, NwAvGuy found himself banned from the forums. He proceeded to design O2 for maximum benchmark performance to prove his points. It’s large and heavy, so hardly worth consideration as a portable amp, however, O2 so far lives up to its name.

c421: Quality Inspection 2

We hoped quality control of c421 enclosures wouldn’t turn into a saga, but here I am posting a progress update. The second batch of enclosures arrived in much finer condition than the original run. Although better, we also rejected batch #2 due to minor manufacturing scuffs. Dozens of phone calls, e-mails, and meetings later, we’re approximately two weeks away from receiving enclosure batch #3…

Therefore, the November 14th ship date may slip. We’d rather ship great products late, than ship ‘okay’ products early. All c421 preorders will be held until the final batch of cases are available. Onto the good news:

  • Anyone who has preordered may request immediate shipment in a batch #2 case; final enclosures will be made available in a few weeks (free + shipping).
  • Samples were sent to professional reviewers last week, and initial feedback of c421 is strong! Customer Tony .G writes:

    “Got the headphone amp and wanted to say that I’m quite happy with my purchase!  Can’t wait to put in some good listening time.  I’ve just given it a limited run and it is quite stellar.”

  • Hexibase of PWK Designs posted a great unboxing:
