Doubt the GO450 had the power to make 500s great, I would have ordered GO1000 if I ever intended that match up.

Did you read any of this thread first? Just going back a few pages will give you an idea.

going back about 15 pages basically told me that the GO has heating and volume control issues. People were also over expecting for a cheap device. currawong did compare it to the ak240 briefly, mentioning that it was a little flat compared to the ak240, but no nobody did really mention about whether it is a warm or neutral sound from what i read at least

Heat really isn't an issue.  Since the amp is running class A it's expected and the unit does get warm to slightly hot.  There is a volume control issue that should be addressed in the next firmware release.  Considering the cost of the Geek Out (max $299) and comparing it to the AK240 ($2400) being just a little flat is a pretty amazing accomplishment.

 

When it comes out, the Geek Wave XD 128 ($899) should compare and/or exceed the current AK240 performance.  Mind you it's all on paper at this point but the design should allow it to compete favorably.

Has anyone here compared the sound of the line-out (DAC only) between the Geek Out and the nano iDSD yet? By extension, can anybody compare these to the CLAS -dB or the Centrance DACport LX? I know they all have their differences and extras but in the end, which do you feel has the best USB DAC?

See the recent reviews of each on Audiostream. I have owned both at different times. Both are great sounding, but the iDSD had too much hiss even at low volumes for my very sensitive 846 IEMs. A shame . But they are coming out with a resistor attachment to address this Issue with sensitive IEMs) both on terms of hiss and usable volume control).

I actually just did (I saw your comment about the hiss)!! However the more impressions, the better help for all of us right (supposedly)? Do you agree with Michael Lavorgna's impressions or were you not able to use them with separate amps?

Since the 846 are so sensitive I didn't want to go the external amp route. Also for portability reasons.

I have used the 450 with an external tube amp the MiniWatt N3, with my HE-5LE. That combo sounded great. Superb bass and detail. 450 with tubes is an excellent combo.

Regarding hiss and IEMs, here is my quick report for today.

IEMs and Headphones: UM3X, Heir Audio 4.AiS, NAD HP50
iDSD nano with latest official firmware from last week
GO450 with 3D feature off.

Music not playing but iTunes launched. Volume controlled by knob (iDSD) or buttons or software (GO450)

GO450 in MacBook Pro retina: no hiss at all on any phones, even with volume cranked via Audirvana or GO buttons. Dead black.

With iDSD connected to MBPro: slight hiss at 3pm and higher on knob for all 3 headphones. Truly only real noticeable at vol max out, 5pm.
Considering volume is VERY loud at 12noon on knob for all 3 headphones, I consider the hiss on the iDSD nano a non issue.

YMMV

YMMV indeed. That iDSD hiss was there for me from the very lowest volume setting. Synergy and component matching is key. Fortunately the iDSD is available from sellers like Music Direct with a good return policy. Once you have narrowed down your options always best to try for yourself.

Has anyone figured out a simple way to use the GO1000 with an iPad?

Is the CCK + a powered USB hub simple?

 

iPad2 running CanOpener app - CCK - ADL Formula2 USB Type B mini - Ultra Aluminus USB hub - LH Labs GO1000 - Beyerdynamic DTX 501p

It's not quite what I had in mind, because it adds to the pile of wires and power cords and really limits portability. Does this solution apply to the GO450 also, or can it plug directly?

You will need the CCK in any event, it's the only way it can work.

 

In a perfect world the GO would plug directly into the CCK with no other wires, however in the case of the GO1000 the iPad's battery power is insufficient for that, so a powered hub is required, or a y-split USB cable with the power lead going to a USB battery.

 

I don't have a GO450 to test so I'm not sure what the possibilities are there, however I'm betting the same set-up would be needed as the iPad is only going to allow something like 99mA to be drawn from it's own battery before it gives the "insufficient power" message, for any USB device you wish to connect.

 

I'd bet the GO450 requires more than 99mA.

 

Somehow the Resonessence Labs Herus manages to operate just fine directly connected to the iPad via the CCK, and sounds great too but is not as powerful as the GO is, at about 130mW @ 32 Ohms.

 

I would imagine the GO100 currently in beta testing might be low powered enough to work like the Herus does when paired with an iPad.
