GIESELER KONVERTER DAC original tube version

 

First a bit of background on the Konverter.

The whole design was a big step up & a lot later than my previous PDX designs.

Hiface USB board replaced with Amanero USB (as used in Gross)

Digital board - a completely newer design with better parts & layout.

The Konverter also has a optical LDR shunt remote control volume system - using my own remote board see photos. Also uses same remote control as the Gross

This worked & sounded  much better than the previous  PDX design which was based on a brought in remote kit & used the LDR's in a standard pot setup.

Relay muting for silent switch on/off.

Single tube output stage using a hybrid mu follower design.

This also has auto bias so great for trying different tubes.

Fitted tube is a Genalex Gold Lion E88CC.

Remote function is very basic being volume up or down.

There are two digital inputs.

Async USB using the Amanero Combo384 board.

Coax using a Wolfson WM8804

Build date was mid 2014

 

The Konverter was never actually released so this is the only one. The parts spec was very high  - Jensen 47 + 47 500v main ht filter cap. Cree SIC diodes for ht rectification.

Audio note tantalum resisters for IV on the 2 x PCM1704K DAC chips.

Nichicon KX pre HT filtering. Elna Silmic caps used for DAC decoupling & Nichicon fine Gold for DAC PSU.

Munndorf M Cap Supreme silver gold oil coupling caps.

Superb Duelund VSF output capacitors.   This model would have been about $6k

The faceplate is rear engraved 10mm acrylic & was intended to be rear illuminated.

See original Stereonet release night in Melbourne.

The price of $1850 is well below parts cost alone so this is being sold on a "as is" basis.

However I will provide a fourteen day warranty (RTB) so everything can be confirmed as working Ok. This unit has never been sold & only used for demo purposes.

It has been thoroughly tested & checks out fine.

Delivery is included in the price & will be via courier.

Sorry about the photo orientation - SNA add editor has a mind of its own!!!  Now fixed!

Have one similar to this, a PDX DAC with Konvertor tube output stage. It's a really good DAC, that makes a Yggy sound digital in comparison. Can only imagine how good this will sound!

Hi Mike,

no this Is based on Burr-Brown PCM1704k  DAC chips which are multibit R2R. 

All the Klein DAC’s & the Gross DAC use delta-sigma style chips which are very different.

@georgehifi another dac with 1704 chips

Hi Mark,

ok

6922 series

ECC88

E88CC

6DJ8

PCC88/7DJ8

No not 12AU7 series which have very different characteristics.

Heater voltage is regulated & auto bias so great for easy swapping of tubes.

 

Also price reduction to $1850
