GIESELER Groß DAC Review

Recommended Posts

Not sure you need to run in the unit much?  Just sit back and enjoy the music... :thumb:

Mine will never be turned off so I don't expect burn in will take long ;)

 

I only power down tube gear.

Below was a question and Clay's answers over several posts on the Gieseler PSU on whether to leave things on. I think it equally applies to the DAC.  I turn mine off.

I have gotten my system to a level that I can even listen at lower volume and still pick up new details during not serious,  enjoy the music sessions.  It is horribly addictive and I spend far too many hours on it.  :wub::wub::wub:

I did an unusual compare yesterday. Not against another 2 channel DAC but a multi channel AVR.

The MRX -1120 came close to the Groß in a limited test and I could easily live with the 1120.

 

What that exercise did was also to highlight once again why I love the Groß. DSD superb, sound stage so wide that it almost replaced the rear channels of a multi channel recording. :wub:

 

 What we did not do was compare16/44.1 non classical music. The Groß does CD quality PCM so well and has this ethereal quality that is addictive (that word again!). Time and time again, I have difficulty stopping and want to listen to the next song. It is this quality that sets the Groß apart. :thumb:

Aye, it has that same toe tapping involvement in the music that a good vinyl setup gives.  Since getting the Groß my wife has started letting me listen to music more regularly....  She'll let me play at louder volumes than ever before and has taken to humming and singing along with some music. It's a very special unit.  I think I'm going to wait for the budget version to come out for my second,  downstairs system. I was tossing up a used Klein DAC though from what I've read its a very real step down from the Groß so best left alone

@MattyW Involvement with the music is a good way to describe the Groß . :thumb:

 

It is good your wife is starting to appreciate the music. My better half listens to the Groß almost every evening, with no change ! She appreciates music that she knows but does not look out for AQ  :(:huh:

Yes, the results are so good that I'm going to need to take it downstairs and try it on my secondary system. If great down there I'll be eagerly awaiting the budget version which will be replacing the Klein DAC series. I considered getting the Klein that's on the classifieds right now though I believe it's a fair jump in SQ between it and the Groß so I need to be patient.

Updated my original review with latest setup (upgrade to SMS-200 Ultra!).

-----------------------------

Had the opportunity to compare the Groß with the 2Qute and PSA DataStream Jnr (with Redcloud firmware)

The  Groß comfortably beat the 2Qute with better detail, sound stage, clarity in Max's setup.  Had the same 2Qute in my system as well, with the same result.

 

Had high expectations of the DSJ given the many comparisons done between it and the  Groß.  But the DSJ did not meet those expectations which surprised Max and myself.

Just thought I would post a couple of pics of my GroB with the outer silver body powder coated in black.   Looks bloody good 

 

Now that I’ve had the DAC for a few months, and have bought a pair of Spendor D9’s the imaging, detail and overall musicality of the dac never ceases to amaze me.  This is one amazing piece of gear.  Why pay 8k or more when this dac is every but as good, if not better 

 

You really are a magician Clay

That doesn't surprise me - I did a comparison with Redcloud on the DS - it was closer, but didn't write it up as we were getting strange driver issues in our source.   That's when I got fed up with drivers being required on Windows machines, got a Mac plus Audirvana, and that seems to be working fine.   Its actually so good when you use with a Uptone Regen (plus of course Clay's supply he designed for it - yes folks his supplies are quite versatile) I probably will get rid of my two Auralic's - after doing a compassion - naturally.   Trouble is getting people to help me in doing it.   Rawl99 often helps me but he hasn't been well and because of that is taking longer to finish a job in Townsville and cant help until the end of the month. 

 

I had a Chord DAC and Clay upgraded its supply - it was the first DAC when so upgraded was able to slightly edge out the previously unbeaten PDX.  That spurred Clay to create the first Konverter which was valve based (I have one for sale - or rather traded in to Mike who hasn't put it up for sale in the classified section yet - have to get him to put it up).  However the Konverter has been surpassed a lot by the Grob - so it's no surprise the 2Qute wasn't up to the Grob.   There is a DAC that when Clay heard it sent him to think about how to improve the Grob - I wont say any more on Clay's forum - you can read about it in the Best System Yet Heard on Mikes forum - Clay can comment if he likes.

 

Chord though has some interesting new products - don't know if the are better, or worse, than Clay's DAC but the designer Rob Watts has some interesting ideas such as a million tap filter.   He thinks MQA has got it wrong - the ringing from steep filters isn't the issue for why hi res recordings sound better - its because the filters used to convert the hi-res it's recorded at to what you play it at are rubbish and you need really precise filters (a measure of which is the number of taps used - technical lingo for the number of samples in calculating the filtered output).  To that end he created - get this - a one million tap filter.   Way overkill?   At the moment it's only available in a rather expensive up-sampling transport - but that is expected to change.  It's interesting:

 

So Clay brush up on your applied math (I am available for tutoring at a reduced price), signal theory, take a few minutes to get a PhD, and build us one for the Grob:na::na::na::na:

 

Oh and having to get one of those beasts we need to save money elsewhere - how about a DAC with a headphone output that is 9W into 8 ohms to drive speaker and save on an amp:

https://chordelectronics.co.uk/product/hugott2/

 

But that should be no problem with that PhD - so get cracking or do you need the leather gear again?

 

Seriously it is interesting - we really don't know that much about what makes audio sound good - it's all very interesting.

 

Thanks

Bill

This could be a very interesting development indeed. Mind you I'm in heaven these days (Gross > Schiit Saga > darTZeel NHB-108 copy > Aurum Cantus F620 speakers) so don't realistically expect much improvement from here on in.

      Item: Electrocompaniet ECD-1 fully balanced 24-bit 192khz upsampling DAC
       
      Location: SYD - Inner West
       
      Item Condition: good cosmetically and excellent functionally
       
      Price:  $650 (was around $4k new) - $15 donation to SNA on sale
       
      Reason for selling: NLR, clearing space
       
      Payment Method: Pickup – Cash, PayPal (friend or add 3%)
       
      Extra Info: 24Bit 192KHz upsampling DAC from Electrocompaniet, the same DAC that was used in their legendary EMC-1 UP CD-Player, accepting 16 - 24Bit inputs. Four inputs (1x XLR-AES/EBU, 2x RCA Coax and 1x Toslink) accepting 16-24 bit input signals. Two digital outputs (Toslink & RCA) and two analogue outputs (XLR balanced and RCA single ended). 
       
      Sound is very musical and smooth with that lovely Electrocompaniet house-sound. Great detail and dynamics, built like a tank and with the exception of a USB input (no USB) can still very much hold its own nowadays. Turns a half decent CD player (used as a transport) into something quite amazing ... or grab yourself a USB to RCA/Toslink converter and use with any USB source.
       
      The DAC is in excellent working condition, there are some minor blemishes on the perspex front and the top of the unit

      Happy for serious interest to inspect in person (pm me please). Local pick-up will be given preference, but would be able to pack safely and post at buyer's cost if required. Happy to deliver free of charge within the Sydney Metro or close by area.

      Location: SYD - Inner West
       
      Item Condition: Excellent
       
      Price:  $1,650 (was around $4k new) including insured postage in AU (discount for local pick-up) - $25 donation to SNA on sale
       
      Reason for selling: No more second system (and not again for at least another 18-24 months), clearing space
       
      Payment Method: Pickup – Cash, PayPal (friend or add 3%)
       
      Extra Info: Fantastic DAC from Metrum Acoustics in the Netherlands, non-oversampling, with two optical, RCA coax, BNC coax and USB inputs. Outputs are either RCA unbalanced or XLR balanced. Fully dual differential design with eight DAC chips per channel.
      Sound is fast, detailed, organic (not "warm" or bloomy) ... music just sounds "right".
       
      This was reviewed exceptionally well by a great number of people and is a very reluctant sale. I actually would not be overly sad if it doesn't go, even though I am under strict orders by the boss to clear out a great number of things due to space constraints 😀

      Item: Bel Canto 3.7 Dac/Preamp
      Location: Perth
      Price: $2800.00
      Item Condition: Excellent
      Reason for selling: NLR
      Payment Method: Pickup - Cash, Paypal, COD Only
      Extra Info: In excellent condition, recently purchased from fellow SNA'er.
      I would happily keep this Bel Canto as it is an awesome Dac/Preamp and I have had a few quality dacs over the past 18 months to be able to comfortably say it even bests the highly regarded Luxman D-06.
      Unfortunately this has to go as I have just purchased a pair of Mola Mola Kaluga mono blocks at considerable expense and I need to claw back some funds.
      Happy to post Aus wide in original packaging at buyers cost.
      If using PayPal buyer to cover fees.
      Well below current RRP $7070.00
