Here is my impression. I owned FiiO E11, TF10, and W4R too.

iphone 4s+Go-Dap X:
The improvement from without amp or with E11 to the Go-Dap X is incredible. The details that I never heard before with the previous setting come alive. With more details in low, mid, and high. However, the quantity of bass is somehow lagging while mid and high are superb. This might be the characteristic of OpAmp MUSES8920. I didn't try the other OpAmp OPA2134. Bass boost function will bring back the bass with slightly loss in clarity but that is acceptable. From what I feel, MUSES8920 improve mid and high not to the next level but getting closer. TF10 might get some push back in low but mid is improving a lot while high is extended further. W4R's bass is completely gone T_T but high become alive. TG334 might be the winner here in term of improvement. High become clear and more forward comparable to mid. Bass is a bit gone but tighter and more details. Sound stage is not that wider but definitely deeper compare to E11.

Thanks for the quick impressions. I think I read another set of go-dap impressions that were similar to yours about losing a little bass but greatly improved mids and highs. Good to know its a clear step or two over the Fiio stuff.

I wonder how much the V-moda version will deviate from this sound?

Is Vmoda licensing another version again?

Somehow I can't manage to post a picture in this forum. Here is some pictures that I put on other forum. Yes, it in Thai language.

I just notice that bass boost function won't work in USB DAC mode.

AFAIK,this is the first portable DAC/Amp that officially supports iDevices & USB audio. E17 is USB audio only.

You may wanna jump to the very start of the thread to see what the X has to offer.

Sony is making another DAC/Amp for both PC and iDevice. I wish companies caught onto this idea earlier. If you already are building a nice DAC, you may as well increase its versatility.

VentureCraft has shared me this video clip of a Samsung Galaxy S3 (Android JB?? Let me confirm!!) with the Go-DAP X :-

So, if this works, then the Go-DAP X is not just Apple iDevice, PC USB, but also Android JB USB Audio compatible.

Yep, it seem anything with iAP support seems to be pricey - Go-DAP, HP-P1, or CLAS - thx to Apple. USB DACs on the other hand are much cheaper. Nothing much can be done about that unless someone manages to convince Apple to support USB DACs on their iDevices.

Within the iAP supported DAC/Amps though, the Go-DAP 4.0/X is probably the cheapest starting from the base model. By the time you upgrade the OpAmps, etc. then it's slightly cheaper than the HP-P1. The CLAS on the other hand needs a budget for an external amp still so ends up being the most expensive option (but it's a good DAC and combined with the Rx Mk3 Amp makes a really good sounding package).

There are ways to get some USB DACs working with iPad/iPhone. With the iPad, some DACs need to find ways to fit in under the 20mW limitation set by iOS 4.2. Alternatively is to carry around a power pack for a USB hub (i.e. powered USB hub). That gets bulky - not to mention a workaround and who knows what Apple will do next to kill this option. Similarly, for the iPhone, you'd have to jailbreak the iPhone to use the CCK (designed for the iPad), to use a USB DAC. Although from a geek techout perspective these options are cool, they're subject to change whenever Apple finds ways to close this loophole.

That's why the Go-DAP X has so far been the only DAC/Amp that officially supports both USB and iAP in a single package - for ~$420 (based on today's exchange rates), that's not too bad considering the other alternatives, HP-P1 or CLAS are more expensive and are limited to the iDevices only.

By just looking at DAC performance, which is a better portable DAC to further improve the sound quality , fostex hpp1, CLAS, or GO DAP X?

With the VentureCraft Go-DAP range, the DAC/Amp are in an "all-in-one" package. Can't use one without the other unlike the Fostex HP-P1 and of course the CLAS. So I could never compare directly DAC-2-DAC only. Wish I could answer your question there.

OK. Lets compare apple to apple.(DAC + Amp)
How is the sound quality between Go-DAP X vs Fostex HP-P1?

My personal opinion, I did sell my HP-P1 last year after buying the Go-DAP 4.0. (and the X doesn't sound any different if you don't press the ASR or surround sound buttons). Personally for me, the HP-P1 was just too mellow for my tastes. I also preferred the upgraded Go-DAP 4.0 over the CLAS+Pico Slim & CLAS+SR-71B.

googled them both and they have the specs on the Asahi Kasei website, but I`m not really sure what to look for wink.gif

(i would post links to the spec pages but I`m not sure about the forums rules).
From AKM website, I could not find AK4353 but AK4480 the one used in HP-P1 is not the best DAC chip.
The best is AK4399 because it has the highest S/(D+N) and lowest THD.
