Gieseler DAC Reviews & Impressions

Recommended Posts

Been going through the Gieseler DAC threads to dig up owners’ reviews & impressions over the past 2 years.  Together, they provided an impressive picture of how well Clay has made his DACs and has lead me to consider  purchase the upcoming Groß DAC with balanced outputs.

Hi Guys

 

Did one early on against the Killer DAC which is much much more expensive.

 

Considering the price difference everyone was impressed with how close it was.  Later it was at a comparison with the Killer and PS Audio Direct stream.  Same result - shocking how close it was and the price difference - you went - how is that possible.

 

But Clay's later DAC's like the Konverter and a new one he has mentioned on this forum he is working on is the natural choice to compare to these much more expensive DAC's.   I have done that one with the Konverter - well I wouldn't like to make the choice.  You have to hear all three to decide.  I have a Killler, a Direct Stream an may just have to get Clays new DAC.

 

Thanks

Bill

I did see your comments in the threads but wasn't sure whether to include it in the links. :sorry:

 

Looking forward to seeing your review of the new DAC when it comes out.  Hopefully Clay will update us soon on an approximate timeline.

Hi guys & thanks for all the positive comments.

The new DAC only is extreamly close now.

I actually took a prototype version to Lenehan Audio last week which we had a good listen to via some Lenehan ML5 references.

I must admit I get a bit nervous when trying out one of my new products at Mikes as he always gives an honest (& ruthless) opinion & past experiences have not always had a good outcome.

Well the prototype passed with flying colours which was a great relief! I was about to order  $1k plus worth of transformers from Jensen so I just wanted to be certain the new DAC was right up there sound wise. It definitely was!

The bonus is that although this is just a straight DAC we have managed to include variable output level (on remote) by using the AK4497's  internal level antenuator. This is done in digital form so you are throwing bits away with lower volume settings but fortunately due to the AKM's 32 bit architecture & as long as you are not listening to very low levels it shouldn't be a problem. 

Bottom line is the new DAC will drive a power amp directly so perfect for a nice simple set up & this is how we tested it at Mikes.

Max output level is 1.8 v rms but this seems fine on the three different power amps I have tested it with so far.

I'm working on the final board layout at the moment so hopefully I will be ordering the pcb's in about a week.

As the finished product is very close I will start a new product release thread shortly with lots more info & details.

Hi Clay.  Sounds like you're gonna be busy when the new DAC's ready!!  Silly question, but is it recommended to use one of your power supplies with your Konverter/new DAC, or is this already covered with the design?

Hi Mat,

All my designs have multiply low noise internal PSU's & run off external transformers so require AC input only.

So the answer to your question is - No 

None of my PSU's would be suitable as they are all DC output.

Hi everyone,

 

I apologise for the messines but at the same time I would like to thank Richard @Suopermanni for bringing his Grob over today for a listening session.

 

We compared the Grob to my Geek Pulse. The Geek did have an unfair advantage in that it was being fed by a Microrendu and the Grob direct from a PC.

 

We both listened for about 2 hours and in every song the Grob won out. Kinda the usual stuff, it was more relaxed while still presenting an extemely full representation. It bettered the Geek in bass control, impact and detail. The highs also showed a little more detail. I don't know what happened to the mids but on male vocals they weren't as pronounced. This may be a more even display but I am not sure. 

 

The Grob was certainly better in all regards apart from mid forwardness but as stated that may be a truer representation. A beautiful DAC and as has been stated before most likely is better than the PS audio DSD. 

 

A real credit to Gieseler and especially at this price point. Thanks again to Richard for bringing it over

@Bunno77 Very interested in this comparison. Which version of the Geek do you have?

I have the Geek Pulse S Infinity which I believe is the top model with the lps1. 

I was also using it with a microrendu with its lps1 which is a big step up from using a pc. So just from that the Grob was at a disadvantage but it sounded better in all but the mids but maybe that means it is more balanced?

Great, thanks. Mine is further down the range than yours. I have the Pulse Fi with a 12v PSU from Clay, fed by SOTM SMS200/Regen so our set ups are not dissimilar. If the Grob betters yours fed by PC, it will be more so with mine I imagine. Thanks for the info.

Yep, will be a bigger margin for sure. The Lh Labs LPS also has the benefit of the USB signal being fed to it not the DAC itself. It strips the 5v USB power so removes the noise on the line.
Makes the Grob even more impressive.

If the Groß showed sampling rates on coax or optical instead of just usb, I’d consider it.

      Item: Vitus Audio RCD100
      Location: Blackheath NSW
      Price: $7900 now $7400
      Item Condition: perfect 
      Reason for selling: 
       
      I really want this sold, at this point to fund other hobbies. I believe this is the cheapest this unit has ever been offered on Stereonet, and this is also almost certainly the lowest hours used, in commensurate condition. A world class DAC, with a matching CD player thrown in for free.
       
      A number of reasons have led me to the decision to part with my stereo, but ultimately work has meant I am simply not listening to a beautiful stereo in a big house that I am never in.
      So I am downsizing, and with it selling a stereo that needs room to breathe. This is an opportunity to pick up some mint condition items that have very low hours on them. 
      I also still have two voodoo power cables left.

      Payment Method: Pickup - Cash, Paypal, COD Only
      Extra Info: this unit was bought from the Australian importer as New in 2014, and has spent over half it’s life in its original box hence the sale. It is literally perfect condition with less than 500 hours clocked. It was paired with the matching RI100 and a pair of Sasha’s, both already sold. This item would be ideal for a new buyer. I can’t find a fault with it. No scratches, marks, or fading. It sounds as good as the reviews say, and retailed new for $18,000, representing a saving of over $10,000 as I would like it to sell promptly.

      Item: Audio Aero Cd players, Dacs and Amps
      Price Range: Any
      Item Condition: Used
      Extra Info:
      I have one Audio Aero product which I find fantastic, so I would like to have more.
      It is also a fact that the range had many issues and there are many bricked/obsolete/broken/half working/not working products all over the world, especially Cd players.
      There may be ways I can get these non-working items working again.
      Anyway - I am looking for those items that people don't want/need. 
      Please and thanks.

      Item:  Antelope Zodiac Gold Dac / Voltikus Power Supply with extra
      Location:Mill Park 
      Price: $2500
      Item Condition:7/10
      Reason for selling:Downsizing 
      Payment Method: Pickup - Cash, Paypal, COD Only
      Extra Info:
       It's time to part with the dac now 
      Antelope Gold with PSU is a great combo that has obtained great reviews around.
      And to get the best out of it,
      I replaced original dc umbilical cable with Paul Pang's (PPA audio )Custom Dc cable and Revelation Audio labs's  Parable CryoSilver Reference umbilical power cord(Jeezz,that's long)
      To be honest,I'm done with RAL dc cable as those of who owned their dual usb cables might agree RAL's wire can dramatically bring up the clarity and resolution.
      However, Brad(RAL) got the wrong Wiring on the mini xlr end so I had to rewire it by removing the heat-shrink tube as I don't want to spend another couple months for the cable to be delivered:(  ,sonic wise no difference IMO
      BTW,Those AudioCadabara brand isolation rca cups will remain on the unit unless you wish them off
      Some reviews below

      Update:just realized on the first pic there are two red marks shown on the Power supply.Those are dirts and has been removed.

      Item: M2Tech EVO DAC TWO DAC 32 Bit DSD/DXD
      Location: Forestville NSW
      Price: $500 + postage
      Item Condition: Used, good appearance
      Reason for selling: NLR
      Payment Method: Pickup - Cash, Paypal, EFT PayID
      Extra Info: I'd bought this new and it has been a good and flexible DAC when needed. Comes with remote and volume control. Boxed and ready to post. One point to note is that it is by default USB bus powered ie it gets it via the USB cable connected to the source. The optional choice (and I'd recommend) is to use a Linear Power supply (LPS). The input Voltage is pretty flexible with 7.5V to 15V.
      Was bought about $800 - see current advertisement here https://www.ebay.com.au/itm/M2TECH-EVO-DAC-TWO-DAC-32-BIT-DSD-DXD-NUOVO-GARANZIA-UFFICIALE-ITALIANA-/252599099022
       
      Let me know also if you want interconnects, USB cables, even a LPS (I have a few options for all of these).

      I am no longer a virgin to an external dac. Almost 30 years of Audiophiling without ext. dac I am now orgasming chord qutest..what a product, a work of art indeed and the sound to satisfy my ear drums for many years to come.
       
      Q. Could someone please advise what (line level output) voltage setting for an integrated amp. (SV-238mk) 1v, 2v or 3v?
