The warm-up period does not refer to the temperature of the component itself, it's more about the internal electronic parts reaching a thermal and electrical stability. So, no worries about being in a cold room, and as was said above, give it until the 4th or 5th to really assess what you have. Congrats on finding your end-game DAC!

Thanks

  I'm already very impressed with the Gumby and it's really only been on for around 2 days now
 

 
My Gumby sounds best after around 10 days of warm-up. Never heard any DAC that does Piano better (apart from the Yggy maybe..)

10 days lol. I actually work out of town for 14 days on and 7 days off, so I don't really plan on leaving the Gumby on for the 14 days when I am not even at home  But I am actually extremely happy with how it sounds now after around 2 days time...But I won't complain if it gets even better

I've heard the Yggy at a meet, and own the GMB. I love the GMB, but thought (in brief listening) that the Yggy was a bit more resolving.
 
I remember a comment by Jason on his thread (months ago) that he prefers the GMB to Yggy for his home rig, due to the slightly warmer sound. FWIW.
 
I recently changed from using an AQ Cinnamon toslink to a Wywires Platinum USB connection between my MacPro and the GMB. So far the SQ is great. I was a bit annoyed with the build quality of the Cinnamon. I was also apprehensive about going back to USB, as I'd had issues in the past with slow data transfer that caused the DAC to hang (on the bad data). Have not experienced any issues since going to the Platinum cable.
 
Happy New Year / Sylvester to all.
 
Enjoy your music!

  Actually there are plenty of Thunderbolt audio interfaces - in the pro audio world.  No reason why they couldn't be used for hi fi.

 
I do -- see my signature.

Absolutely not. Optical actually sounds better than usb. Just check if the adapticlock light in the front is blinking. If not you are good to go

Just got everything set up.. Took several hours and trips to best buy but wow...
 
Mjolnir 2 + Gumby sounds amazing.. I was really handicapping myself with the Momby.
 
Ugh wow I haven't stopped smiling since I put on the HD 650. The soundstage sounds bigger on the Gumby than my Momby and more engaging too. Love it.

I've been enjoying this set up for almost a year now with both my 650 and 800S and it is very, very good. Congratulations!

I was shocked when I got around to doing the same DAC comparison in my speaker system. I enjoyed the Momby on headphones. It far surpassed regular Modi, and (to my ears) edged into the space between m9xx and Mojo. But at a price so much lower, it truly rocked the value of DACs forever!
 
But once I listened in my more resolving speaker system, the difference was obvious. Same as what you heard, the soundstage of the Gumby was much bigger. I've not heard the Mjolnir 2, but the more I read about it, the more impressed I am with reviews of it. I'll certainly need to consider, if they ever accidentally make it in black...

Anybody else using a Mac Mini as a source to the Gumby?  How are you connecting the two? USB, optical, USB to SPDIF converter?  What cables are you using as well?

Cheers,

  BHSE is 400 volts, 1600V PP, IIRC.

 
400V rms = 1131V p-p
1600V p-p = 565.6V rms
 
Is this correct?

What year of Mac Mini do you have?

 

[nasiemp]

Mid 2010/early 2011.

Well, the 2011 or later Mac Mini has only 20 ps jitter on the optical out, which is good enough to make it the preferred choice.

 

[nasiemp]

Cool! I'll give the mini optical connection a try and see how it compares to USB with the audioquest jitterbug.

Both should be well below audible.  If there is an audible difference, it's not from jitter.

Recently bought a Jot and loving it so far. Thinking of getting a gumby or bimby. Will be using hd650s or 400i's. Basically looking for some convincing opinions to help me decide.

Keep the jot with the internal DAC and get Chord Mojo so you can have portable bliss too. If you only listen at home, definitely gumby since jot has balanced topology.
