Klein DAC II

Recommended Posts

The audio circuitry is very similar to the Klein but all the digital supplies have an extra regulation stage so there is better isolation between analogue & digital supply lines. Also there is an extra filter called "super slow roll off" which is rather interesting.
Because the filters can be switched via the remote it is much easier to hear the differences. Sit it the sweet spot, crank it up a bit & flick through the filter settings. With DSD you have 64 128 & 256 - no 512 until the AK4497. Not a big deal as I've yet to find much DSD 512 content. With DSD there is also bypass mode which skirts around quite a bit of internal circuitry within in DAC chip itself. We spent a lot of time on the muting to eliminate pops/ticks but you still get the odd one say if you jump mid stream on a DSD track to a PCM track.
The good thing is it is easy to swap the chip so if we improve the software down the track I can always send out upgraded chips. Beginning to feel like Ted Smith now ha ha.
Yes I agree the toggle switch looks a bit out of place so maybe remote power on & 12v sense out - good idea todagt
The output is fixed at 2v RMS but as we have software control it would be possible to utilise the DAC's internal digital attenuator.
We may make a variable output version available with a different remote if there is enough interest. A little bit risky though as the DSD bypass mode is on the remote so you could go from low level to max with one click, anyway something to think about.

Looks nice! Will it come with balanced outputs?

No balanced out on this one but we may make it an option on the bigger version.

OK I might need to get a toggle switch vote.

Looks great, Clay! I think in this case the toggle is a necessary requirement for ease of service and build. Perhaps another option for those who dont like it would be to move the toggle to the rear panel and use some sort of standby mode instead? I personally like the engaging feeling of a solid toggle. One must be careful when moving all controls to a remote especially if the user/owner happens to misplace the remote it renders the gear completely inoperable until a replacement is sourced.

I have the Klein SE Dac. In the beginning looking at the the toggle switches irritated the living daylights out of me. Now I just don't look and it does not bother me. 

From a visual point of view as well as a OCD point of view I would not choose a toggle switch in the front. If it is at the back I think it would be much better.

The remote is a great idea!

Having had this happen to me recently after one of the kids was fiddling with system - this is something worth avoiding !!

Oh cool, a new Klein DAC!!!

 

What DAC chip does it have or is it the same as original Klein DAC?

 

Is this superseding the original Klein DAC or is it still going to be available?

Specs - I will list it all properly in the next few days.

DAC chip - same as the Klein, AK4490EQ.

It is basically still a Klein but with DSD & remote control plus a few other PSU upgrades.

There is quite a bit more technology in it plus display & remote so that has bumped the price up a bit.

Also there was a fair amount of time spent on the software/firmware for the micro controller but this certainly makes it a more flexible design.

The standard Klein will continue as not everybody needs DSD or remote functions.

Clay,

congratulations, it looks superb and I like the toggle switch too, but for sonical reasons I would vote to get rid of the switch to have the DAC always powered.

Nice looking unit !

A DAC / PRE with balanced out would definitely be something I would be interested in purchasing given the great feedback you are receiving.

I would prefer no toggles !

Hi Ray,

We are currently designing a higher end unit which is a combination of this DAC plus my Preamplifer.

There will probably be a balanced out option on that model.

No toggles either - full remote.

Analogue inputs (at least one) I reckon is a must. Colour me keen if that box is ticked!
