Initial impressions:  Spacious, detailed, very neutral.  Runs really hot.  It makes noise when handling it, but is very quite when left alone.

 

It appears to match the W1000X better than the Sony MA900.  I guess that's because the Sony MA900 is also very neutral.  The W1000X adds a bit of warmth to it.

 

I think it a keeper! :L3000:

 

Give it a week or two of playtime and check back with the MA900s. 

It warms up and fills out a bit. It can be deceiving out of the box as it has good prat and nothing that really shouts out that it needs break-in time but it really improves on already good.

 

Great!  I am glad to know.

 

A bit more of warmth and body will be welcome.

Man.  This Geek Out 450 is seriously good.  I love my HD600 out of it. With the 3D. HD800 and UERM are great with the 450 too, for the most part...

 

HD800?  I can use it straight out of the 450 for most music. Straight out of the Geek, I like the 3D setting.  If the treble is a bit much with some recordings, I tried 450 into the Vali.  Found that I prefer maxxing out the Vali volume pot and using the GO digital volume control for volume when I do. Anyone else find that cleaner too?  With Geek Out into Vali, not sure if I like the 3D.  Combo is slightly more relaxed, not as clean overall. Seems to compress some dynamics to get that more laidback sound.  Not bad, but think I'l just use the HD600 when recordings don't suit the HD800 rather than using the Vali in the chain. If you are a bass person, you may prefer the GO 1000.  The 1000 bass adds some impact and the 1000 treble adds some attack.  Fun but can be fatiguing for me, depending on the music. Using the 1000 to Vali still has a good deal of attack on the treble with HD800 (noticeable on certain recordings).

 

With the UERM, the GO 100 has the least amount of hiss (barely noticeable). The hiss is so low on all of the units that I don't think it is a big deal for most people. I think I prefer the 450 with UERM over the 100 even though it has less hiss and the 450 is slightly brighter tonally.  450 handles the mids to upper-mids to treble transition the best to me and works with HD600/800. Differences in tonality are slighter between 450/100 and greater between 1000/450. The 100 noise floor is not different enough to justify keeping it as dedicated UERM GO. With more use, I might be able to differentiate the 100 further but I just wanted to test with it <enough> to see if it warranted buying one in addition to the 450. (I'm sure people will like the 100 too.)  NOTE: The 3D is not usable with iems until it gets quieter and cleaner, IMO.  The 1000 tips up the low bass and the treble with the UERM and the HDXXX.  

 

I'm lucky to have the chance to pick nits and compare these three units with my phones the way I plan on using them.  I think people will enjoy any/all three Geek Outs (four if you include the 720 that I have not heard). I was looking for any reasons to keep only one.

 

Bottom Line:  Since I am plunking down for the Geek Wave X DAP (indiegogo campaign), I plan on selling the 1000.  100 not different enough from the 450 for me.  Hoping there is <zero> hiss on the Wave X with UERM and that the 3D is quiet and can be used with iems.  450 rocks for my uses.  Versatile, resolving, tiny, inexpensive.  Will bring GO 450 > HD600 to Bay Area July Meet to show it off.  :bigsmile_face:

I've found that my GO 100 has a significantly lower noise floor than my GO 450 for my IEMs so I take it with me as my portable rig. I've left my GO 450 at home as a permanent part of my desktop setup. It's plugged into an iFi USBPower, with a line out to a Project Ember. As the heart of my desktop setup, I have to say that it's absolutely amazing. I don't think I'll ever bother with upgrading my DAC anymore, the GO 450 and 100 are as good as I think I'll ever need.

According to their measurements, the Geek Out 1000 has a noise floor of about -145 dBFS at 0 dBFS. What earphones are you using to possibly detect that noise floor? That by itself is already one of the lowest noise floors I've seen.

Yeah I saw the specs for all the versions of the Geek Out so when I was hearing a ridiculous amount of noise coming out of the GO 450's 0.47 ohm output, I thought I had to have gotten a defective unit. So I told LH Labs and they sent a replacement unit. The new unit had the same "issue" so I assumed that it wasn't defective after all. Told LH Labs about it again and they sent me a GO 100, which has made a significant difference. I was using the FAD Heaven V and ATH-CKM500 with the GO 450, both of which were unusable on the 0.47 output and weren't great on the 47 ohm output either. I still don't use them on the 0.47 ohm output of the GO 100 because there's still some noise but the 47 ohm output is basically silent with them. My DITA The Answer doesn't have an issue with the GO 100's 0.47 output and sounds amazing out of it.

Oh wow, that's interesting to read about. Maybe this is why they delayed the Geek Out shipping? Although I believe that was because there was a problem with the case finishing and not the actual circuit. Hm...

Perhaps that's the reason? Although I find that hard to believe, I feel like this issue would've been caught much earlier in development rather than right before shipping out the production units. It's weird because others like DannyBai, who is also using the Heaven V with the GO 450, didn't have a problem with it. But for me to get two defective units in a row seems highly unlikely, so it's really a mystery. =/

They sent him a 100, not a 1000 if I am reading this correctly.

The 100 is still in beta and is designed to address potential noise issues with super efficient IEMs.

Yes Mikey, you're reading it correctly haha.

Or in other words, no noisy circuit problems causing shipment delays as another post was wondering, just super efficient IEMs needing the 100 model. Your 450 units likely weren't defective.

Yup, that's the logical conclusion I came to also.

 

I personally think the GO 720 and 1000 are overkill, unless you are actually lugging around high end full-sized cans on the go, which I don't see many people doing. Depending on how sensitive your portable headphones or IEMs are, the GO 450 is really all you need. For those who have extra sensitive IEMs, there's the 100. And if you want to use the GO 450 or 100 as just a DAC at home, just connect it to a desktop amplifier you probably already have for your full-sized cans to get the power you need. It's seriously an all-in-one solution, LH Labs did something crazy when they came up with this product.

Sometimes I listen on my desktop rig and sometimes I use my laptop around the house with full sized cans so my GO1000 has a purpose. Hence my GO450 is also on the way.

Ah it makes it pretty useful for that application. I guess I don't bother taking my full-sized cans around the house since the cables are just too long and get in the way of portability so I didn't think of that.

I am pretty sure the Geek Out 100 CEE TEE is demoing was the first unit out in the wild. I gave Larry some feedback about the noise floor and it may have been tweaked before the actual beta units went out so take his feedback on the 100 as a YMMV :). I am assuming more beta testing will happen with more feedback soon.

How to play DSD?

So, any hints on how to play DSD with foobar?  I have the foo_out_asio, foo_input_sacd, foo_dsd_asio installed.  I am trying the configurations in http://geek.lhlabs.com/force/geekout/980-how-do-i-set-it-up-properly-with-foobar2000-dsd.html and many variants around it.

 

I got three different results with slightly different configurations and/or rebooting foobar or my computer.

 

-  Error:  Could not set sample rate to 44100 Hz

 

-  Error:  The process receiving or sending data has terminated

 

-  No sound at all.  The blue light of DSD turns on the GO and foobar appears to be playing, but no sound is produced.

 

Any ideas?
