After tons of help from Avro_Arrow, and tons of dumb questions on various forums...

I present, the Twisted Pear Ventus EZ

These are actually the first pictures of a completed Ventus EZ I have seen online, I wasn't able to find any previous pictures of this amplifier for whatever reason
Its built with a Twisted Pear LCBPS, and an ALPS RK27, which is stylishly hot glued to its platform

Case was cut with an Epilog Laser Cutter at school, I designed each piece individually, and since I haven't seen much case design, I figured it'd be cool to post a few pictures of the files in Illustrator aswell

Sorry if I uploaded way too many pics

That case shure is nice looking!

Great job Dutch! Thanks for sharing the pictures.

Good casework, Dutch! The innards however need rearranging badly. Keep everything that conducts AC away from the low level input wires!

Sweet.

Very nice! Were you able to get rid of that hum problem you were experiencing?

My speaker / headphone switch works great.
Everything has been completed. Buttoned up... finito.
The Audeze LCD2 R2's sound amazing ! As do my 15 year old Thiel CS 1.5's
The amp is driving them just fine and I like the sound better than the Zu Audio Soul
Zero static / fuzz / snow / hum.
Stop the music and they're as quiet as a dead church mouse.

I suggest a mini-meet at your house?

Do you have any idea how many watts your 300B amp generates? I only ask because aren't your Thiels 4 ohms & 83db efficient? My tiny SET amp could barely make them whisper

Mullet · Oct 15, 2013 at 2:01 AM

Great job DutchGFX!!! I can't wait to see it and hear it in action at the NYC meet next month! We'll have to do a little DIY talk.

Here's something I just finished in time for the meet on the 9th... It's a world-wide venture courtesy of peeps mostly from diyaudio.com. ESS ES9023 based DAC board with JG Buffer designed by Curryman and Joachim Gerhard in Germany; Isolator/Re-clocker board designed by Acko in Australia; USB Combo384 transport by Amanero in Italy; Sigma 25 power supplies by AMB in Sunnyvale, CA and the chassis by a few peeps in Albany, OR. I slapped it all together and I'm thoroughly enjoying it with my "Wire" amp and LCD-2s...

Woah.....that is absolutely beautiful! Really nice job on that!

Isn't the "Wire" just a gain circuit with no volume control?

Mullet · Oct 15, 2013 at 2:41 AM

Thanks!

The Wire is a fantastic amp... It's compared to the O2 amp - a wire with (unity) gain and a buffer for higher current output. I highly recommend it. In it's default setup it's at unity gain. I added a gain of two because my DAC at the time (Gamma-2) only outputs 1.6Vrms. You can add an attenuator - I did, or some people slap it in with a DAC and use digital volume control. With this new DAC at 2Vrms the extra gain isn't really needed.

Nice work Mullet. That's a whole lot of SMD work.

Yes, very nice, neat build there Scott.

How about a maxi-meet in San Diego, Sat Nov 2nd?
However, I live an hour closer in OC, but it'll cost you pastries.

8 watts into 8 ohms, to clipping, -60.5db floor

sceleratus · Oct 15, 2013 at 12:56 PM

Sometime things don't go well in the process.

Since everyone like a train wreak....

(I forgot to photograph the incinerated resistors.)

It's hard to believe but these Mundorf Silver Oil Caps are amazing.
There was and immediate sonics upgrade over the Solen fast caps they replaced.
A big difference!

Built a nice switch with pupDAC built in.
