Taking orders :)

[Grainger49]

The old saying is that it is hard to get Engineering to let go of their second best design to get it into production.  The best design is always being developed.

Keep up the good work, John!

And keep us updated, too

[John Swenson]

It's all working now, I have the corner cases all working, it just works with everything I'm throwing at it now. I just finished getting the new filter installed. WOW, I thought the old one sounded good, this is over the top, I'm running out of words to describe it. I'm listening to a piece right now that I have heard thousands of times (it's one of my favorite test tracks) and I am hearing a bunch of instruments in the background that I never noticed before, it's amazing.

So all that is left is to hack up Doc's board. The assembler put the wrong part on the board and I have to hack in another chip to deal with this.

Then I'll send it out. So it might be tomorrow or at worst Wednesday for shipping to Doc.

Whew another song just started and I got goosebumps. The bass on this is amazing.

Now that everybody is drooling I'll sign off.

Subscribed as well!

I have yet to finish my Crack/Speedball kit, but knowing this is on the horizon may be all the impetus I need

Shut up and take my money already ugghh

Hey guys,

How's the beast coming? Is there a roadmap for orders in the pipeline? 

Cheers /dom

I just got the new board yesterday. PB breadboarded it  and I ran it a bit late yesterday afternoon, feeding it via USB from my Mac Mini. Happily it finds every sample rate up to 384K and the 7 segment display is rock solid. Today I will test TOSLINK and coax digital inputs, which will be capable up to 96K for now with an upcoming firmware update that will make at least the coax input 192K capable.

John was not exaggerating about the improvement in his software filter. The dynamics are really something else with outstanding resolution and great tonal balance.

PB laid out a new panel for this setup yesterday. It is a little bigger than the last one and includes a bigger battery to help extend the operating time past the 4.5 hours we were getting with the last prototype. We hope to have a "near production" prototype together some time next week.

So what size base are you using now, i assume you are sticking to the 6x10 or 8x10 format to keep it the same as the amps?

Also any chance of a pic since we lost the old ones?

[Paul Birkeland]

The current chassis plate that I designed is a 10" x 10".  The last prototype was on an 8" x 8", but we needed a bit more space for the larger battery.

Cheers to John, Paul B, and Doc for entering a mysterious and uncomfortable arena on our behalf! many of us hope for an All Bottlehead System, and the DAC is an important step along that path. Yay!

Just a brief update - TOSLINK has been tested today and passed with flying colors.

How does it sound, by comparison?

I found a nice NOS Shallco make before break six deck 27 pos switch to build a volume control for my HT so I'll definitely need three dacs. BTW I also have an electroswitch eleven position six decker so I could possibly build a coarse/fine volume control a-la-BH.

Next step is the Bottlehead DAP - The Pocket Rocket!
