Light Harmonic Geek Out EM/1000 Impressions Thread - Page 40

post #586 of 2304

Folks-

 

1.  regarding "DAC section only" comparison that isn't going to happen for awhile.  I don't have a 3.5mm to RCA cable yet to use the GO line out to my Vali.

once I do, it would be a 3 way comparison between: Concero HD, iDSD nano and GO450.   whew.  not sure I've got the discipline to do that properly.   

 

2.  maybe in 1-2 weeks can do a "very short" DSD shoot out with some limited files (some classical, also have 2 new r.e.m. DSD releases)

between the GO450 and iDSD nano with the HP50.

 

due to my usage (multiple offices) and iDSD nano having a battery which makes for great match to iPhone/iPad, don't have any intention on selling iDSD nano even if GO has some slight gains.

I didn't have the chance to compare side-by-side, but I have had both the iDSD and the GO450. Although the 3D circuit is so noisy with my Shure 846 as to be unusable (anyone know anything about a firmware fix for this coming? My one main complaint, other than the odd volume control issue that is being addressed in firmware IIRC), I found it to be much quieter in non-3D mode with my very sensitive (and low impedance) 846s. I was getting a quite noticeable hiss at even the lowest iDSD volumes with the 846, but not with the GO450. There may be a lil hiss, but very very minimal. Unfortunately, the hiss was a dealbreaker for me with the iDSD. Both were faboulous sounding, but for sensitive IEM owners the 450 is a much better bet. 

 

A clear improvement from the 450 out of my new MBA. Still need to compare the 846 from my HTC M8 to the 450. But waiting to see if I can pair the 450 with the M8 (speaking of which, what  Y cable and battery power pack could assist with this if the 450 requires more juice than the M8 can provide?)

Although I don't have a Geek nor use your phone, I suggest a cable like this http://www.amazon.co.uk/Micro-Cable-Power-Samsung-I9100/dp/B00B5T42T0/ref=pd_bxgy_computers_img_z/279-1094129-6404502 or http://www.ebay.com/itm/Micro-USB-Male-To-USB2-0-Female-Host-OTG-Cable-USB-Power-Cable-Y-Splitter-/171330271391 and any battery pack that would at least output 5V/1A as to give enough headroom for the Geek (I think it runs on 5V/0.5A, someone correct me if I'm wrong).

So thoughts on how well the GO1000 powers orthos like the HE500? Comparable to desktop setups?

An easy fix for using IEMs with high powered amps with no sensitivity setting is to use a simple resistor L-PAD in series. Do that and you will never have hiss problems.

Can you point me to a commercially available one?

And are there no sonic downsides to using one of these?

Have never used one so can't make a personal recommendation.  There are many references here:

http://www.head-fi.org/t/424038/high-quality-3-5mm-line-attenuator-pad-my-source-is-too-loud

 

IMO the best solution is to roll your own. 4 resistors, a socket and a plug and you're done. Though some soldering experience is recommended.

As to sound quality, there is as you can see tremendous debate. Can only decide for yourself. The nice thing about rolling your own is you can fully customize it for your IEM. A lot of the off the shelf ones I see are designed for mics and will be far from ideal. The in-line variable volume controls are also most likely to adversely affect sound. The only good approach is custom made, either commercially (I know I have seen an ad somewhere...) or DIY. I could also make one up for a nominal charge if you liked. It would be fun to try it out.

Or better yet, get a real dsd dac.

Some nice impressions regarding HE-500 + GO1000 pairing (however the dude doesn't have a full-sized desktop setup)

Looking for some more impressions though... wondering if they could stack up to a speaker amp in terms of performance? I know orthos dig a lot of current

Speaker amps for the hard to drive HiFiman are going to be tough to beat.

The HE-500s are not that hard to drive.

Good to know, I don't follow the 500s. But models like the 5, 5LE & 6 do sound great out of speaker amps.

Impressions with the 450 and HE-500 mate?

I'm interested in the GO  1000 but the shipping price ($45) to Canada is too much. Hopefully a cheaper shipping option will come in the future.
