Out of curiousity, would the klein dac II as a dac equal the dac/pre's dac section? Just really needing a dac. Also, saving the 2k+ might be problematic atm.

Out of curiousity, would the klein dac II as a dac equal the dac/pre's dac section? Just really needing a dac. Also, saving the 2k+ might be problematic atm.

A similar question was asked in the Dac/pre wish list thread.

Q: "You've probably already mentioned this, but is the DAC stage in the DAC/PRE combo the same as your latest DSD DAC in terms of sonic performance?"

A: The digital/DAC circuit is the same but the power supplies have been improved a little. It terms of performance they are probably very similar. The DAC section in the DAC/Pre is a much smaller PCB than the Klein II because it has no filter/output stage, all that part is on the main preamp board. Also the main raw DC & pre filtering for the DAC is on a seperate PSU board. I think maybe because those two important sections are physically seperated from the digital part the overall sound is a little cleaner too if you follow. I will probably make a higher end DAC only based on the DAC/Pre layout/topology so suit customers who already have a good preamp or intergrated.

Got my Klein II a few days ago and I must say this is certainly an amazing sounding DAC. I have had 2 high end DAC's in my system over the last few years. First one was a Moon 380D (around 7k) which I didn't like the sound of at all so I sold it. My current one is an Antelope Gold DAC (around 3k) which is a great unit but I find that it pushes the highs a bit in the DAC section so it's pretty fatiguing for my ears even after a short time listening. So I'm just using the pre amp on the Antelope with the Klein. The Klein sounds very natural indeed. It's got a real nice full bodied sound and the bass is great. The imaging is so stable and the sound stage is awesome. It's super smooth on the highs which is perfect for my system. I just got new floor standers with ribbon tweeters so the detail is superb. I briefly heard a PS Audio Direct Stream early in the year and I think this is comparable. They both sound warm and not so digital. Also USB audio out of my Mac has never sounded so good. I do most of my listen on my Rega CD player using digital out into the Klein. But the Klein is so good through USB, I think I'll be playing a lot more computer audio now. It's going to be great to hear all my music again through this fantastic DAC.

Thanks for sharing. Did you play PCM or DSD or both?

I would interested to see some further reviews of the Klein DAC ii.  Dsd performance etc. For example Is there any benefit in upsampling from roon or hqplayer before sending to the dac? Has anyone tried the filters?

 

I am looking around at the moment but not wanting to jump in the wrong direction as i currently have 2 inbuilt dacs (moon 350p neo preamp - no DSD) and the dsd capable dac in the yamaha cd-s2100.  Trouble i now have an antipodes ds ssd (latest version) and because the yamaha doesn't like anything that isnt using the steinberg usb driver i cannot connect the antipodes to it so have gone back to the moon dac.  Also using roon.

 

Some dacs considered but not tested; giesler klein dac ii, metrum nos dac, and possibly something like mytek brooklyn.  All very different.

 

The dac obviously must work without usb drivers for linux, would like to have dsd support metrum doesnt).  The brooklyn also has internal functions i dont plan to use in the dac such as headphone preamp etc.

 

Havent come across the dac chip used in the klein dac ii are there any other dacs using that chip?

The Klein II uses the AKM AK4490EQ

http://www.akm.com/akm/en/product/datasheet1/?partno=AK4490EQ

It is the premium DAC chip in the AKM range. The link shows lots of products that use it.

To name a few 

The flagship Marantz & Denon AV Preamps/receivers, TEAC UD503 & Esoteric SACD players.

It is a relatively new design released in December 2014.

Also a interesting link that shows why TEAC picked the AK4490EQ for their UD503

Hope that helps

Thanks Clay

 

I did go back and reread the other threads on the Klein DACII.  Lots of useful information in those which I should have read first, including pictures of the LCD screen on (not shown on the website).

 

Just out of interest someone mentioned a new DAC CHIP the AK4497EQ.  Will that replace the AK4490EQ any stage soon in the Klein DAC, I guess it would depend if that forces you to do a total rebuild of your design?  Secondly, would we notice the difference sound wise if it was replaced.
