Light Harmonic Geek Out EM/1000 Impressions Thread - Page 6

I'm also interested in how the Geek Out does using its line out with an amp.

+1 to that.

Using the DAC part of the Geek Out in a desktop setup with a different amp (Vali) is what I'm considering as well.

Hey Mike, how well does the Geek Out perform with your LCD-3's from a power/current standpoint? I've been thinking about a transportable dac/amp for my LCD-2's, but I've found that they require buttloads of power to really make them sound their best (and I mean speaker amp levels of power). Do you think the Geek Out 1000 would have enough power for them? I was originally looking at an iBasso combo that outputs 2.5w, but the Geek Out may be a smaller and cheaper alternative.

 

Also, does anyone know how much they will cost after preorders? Will it be the same $199 base price?

GO 1000

Serial #000129

Sennheiser HD-600 vi 0.47Ω output

Media Hosted on Synology Diskstation

Playback Software Audirvana+  V1.5.12 (INT mode) on Late 2013 Macbook Pro OSX 10.9.2

 

I played CD rips (Apple lossless format) tonight along with a few HD Tracks titles (Jazz at the Pawnshop) and some DSD from Channel Classics. The unit does get warm but not alarmingly so. Bass is solid. Treble is detailed without any etch or hardness. This is some of the best digital I've heard on these headphones. It thoroughly trumps my Peachtree iNova which while having a fantastic digital section (when listening over speakers or it's line level output) never could drive the HD-600s with the same authority and freedom of harshness at loud volumes.

 

High bit rate audio really does come alive. Jazz at the Pawnshop is spooky. Audirvana+ could not detect that the device was DSD capable but I was able to "force" it via the "DSD over PCM Standard 1.0" option. Channel Classics' Strauss (http://www.channelclassics.com/fischer-24507.html) is absolutely breathtaking. I listened to this one at FULL VOLUME. There's so much easy detail, texture, effortless dynamics, natural bass, etc.

 

At this point (already), comparisons are going to pointless because for the price, I don't think you can get much better. I'm looking forward to going to work tomorrow so I can get hours and hours of listening in. My music spending is about to skyrocket.

 

Future tests: Mr. Speakers' Mad Dog Alphas v3.2 and using the GO 1000 as a DAC in my home system driven by an older Mac Mini.

 

Light Harmonic has hit a Grand Slam.

Sounds pretty promising! I can't wait to try it out.

Does anyone with a Geek Out also own a USB power purifier?  Like the AQVOX, ifi iUSB or the ifi iPurifier?  Interested to know if you can take the performance level of the Geek Out any further by using such devices.  Thanks.

I think you would be better off with the Geek Pulse, which features a lot of the circuit of the Geek Out with a better power supply.

I will eventually have both, but my GO 1000 has not shipped yet.

 

I too will be curious being that the GO 1000 is bus powered. The answer you are looking for will be variable for different users depending on how noisy the source computer is.

 

So a dedicated music server that is not multitasking and/or has filtering built-in such as that from SOtM will likely not see too much of a benefit, whereas a multitasking laptop is notoriously noisy to begin with.

 

That said, I have used the iPurifier with both the bus powered Resonessence Labs Herus and the self powered CEntrance HiFi-M8 and both benefit, though more so with my HP W7 laptop as a source than my Mac mini.

 

The other aspect that no one can advise you on is the exact price/performance ratio, each person's wallet is different (as is their partnering equipment and subjective taste too) so it's tough to assure yourself let alone others that the expectation of a $99 sound quality improvement will be met.

 

I kept mine, I thought it was worth using at work on my W7 laptop, but I also think the area of biggest improvement is when using loudspeakers and not headphones, as the image size and focus are more readily heard that way.

 

The iPurifier is simply an EMI filter that also adheres to a strict 90 Ohm impedance right at the DAC's input. The filtering effect is a 5 dB reduction in EMI noise. There are no other grandiose claims being made.

 

The iPurifier is half the price of competing products like the Empirical Audio Short Block, and Ultra Fi Aubisque, which seem similar in design.

 

The iFi iUSB is both a different price point and a different feature set, as it requires AC power to perform "super regulation" of the 5 vdc and also offers separate output jacks for power and data, as well as a ground lift switch.

 

Your mileage on any of the above will vary, depending on how much noise you have coming from the computer riding on either the USB bus power, data, or ground.

Thanks for all the reviews and imnpressions!  I have a noob question:  Is there any benefit to getthing the more powerful versions if your headphones don't need it (other than "future-proofing")?  According to the site Nico posted earlier, the 450 will push 110db on my Q701, so I don't think I need to spring for the more expensive one (and budget is a consideration).

post #85 of 955

is the base model still considered fine for someone who is primarily an iem user? i could see myself maaaaaaaybe getting some cans down the line, but i'm much more of an iem guy at this point in time.

post #86 of 955

If anyone has HD800s I'd love to hear how the 1000 sounds with them

post #87 of 955
Thanks Mikeyfresh. Good info. I already own an iUSB that I use with an Audiophilleo 2 which does make an improvement on my home rig. Just want to see if it's worth it to get another one to use with the Geek Out, or maybe the cheaper iPurifier. I ordered the base GO so I won't be getting it for quite some time.

Yep, the 450 mW version is recommended for someone only using IEM or efficient cans.

If everything you have is below 100 ohm, then sticking with the 450 mW is perfect. The main benefit to getting a stronger amp is for more difficult cans. Since you have the Q701, I personally would step to the 720 mW version. That model can handle the Q701 with room to spare, still be decent for more efficient cans, and have plenty of head room for future upgrades. I have 600 ohm headphones, so I went with both the 1000 and 720 models myself. I'll be able to compare side by side how they are.

I was Kickstarter backer #173, so I hope I'm not waiting too much longer. I'll let you know what I think about the combo after I receive my GO 1000. I also have the iUSB like you, so I can even report back on the full set-up,.

 

That is the bedroom system I plan to use the GO 1000 in too. I'm using mine as a line level output DAC into a Sugden Headmaster preamp, replacing a Musical Fidelity V-DAC II which sounds great, but is limited to 24/96 PCM and no DSD.

 

If you have a need for more USB ports, another item that offers noise filtering and strict 90 Ohm impedance that I use in that same system is the Vaunix Lab Brick, a high-end 4 port USB hub. It's a ton better for audio than any cheapie hubs that are both prone to failure and have noisy switch mode power supplies.

something else that would be interesting is a usb cable that breaks out power, and running the power tail to a battery supply.
