VentureCraft Go-Dap GD-04 for iPhone 4 - Page 6

I've not tested for jitter yet, but the actual output of the Unit 4.0 is fine. What system were you using to convert the signal to analogue? And when you compared it to other system, you used the same converting equipment? My system isn't that great now for converting to analogue, so I need some time on this. I'm awaiting one piece to allow me to test using my external card. Using my MacBook Pro's internal digital input is pretty poor.

My chain is Benchmark DAC1 Pre -> Stax SRM-727A -> SR-009.

Various transports I've tried are :-
Go-DAP via Optical

Late '09 iMac 27" via Optical

iBasso DX100 via Optical & Coax

Apple TV V1

I also tried a Lavry DA11 prior to purchasing the Benchmark DAC1 Pre. At first the Go-DAP sounded so dull I actually thought there was something wrong with it or the connection. Then trying various optical cables, I realised that this was the best the Go-DAP's optical could do (i.e. nothing wrong with the component chain).

Very interesting. Thank you.

You mean something like this?? :-

It's rather interesting that you find the M80 less punch. Do you mean bass? As for sparkle, do you mean treble? I personally do find the M80 to be a little treble veiled. But it depends on the genre of music. Overall though, I find that the combination works. The AKM DAC and the AD8397 OpAmp does extend the M80's treble somewhat (over straight out of the iPhone headphone jack).

I must admit I cannot remember how the TripleFi 10's sound like as I sold them off back last November.

Will 3rd party audio apps like Equalizer still work with the GO-DAP?  I know many here prefer not to EQ their music, but I need to in order to compensate for a partial hearing loss in one ear.  Besides, I like to be able to tweak the curves to compensate for the deficiencies of the headphones I am using.  Will the EQ still be processed, or is it bypassed by the GO-DAP?

I have to admit I don't remember the Burr Brown OPA2134 since I owned it in that configuration for only a month last year then quickly upgraded to the AD8397 OpAmp. Depending on how much of a bump you're looking for, it wasn't enough for me. I agree with you that the treble in the M-80 is a little flat to a little veiled, at least compared to the other IEMs/headphones I've owned. The AKM DAC to me sounds more detailed and clean compared to the HP-P1. In fact (possibly I didn't have good amps for my CLAS?), I preferred the Go-DAP (with AD8397) over the CLAS+Pico Slim or CLAS+SR-71B.

Note: My opinion of the Go-DAP may change depending on my recently acquired ALO Audio Rx Mk3.

I also don't remember the Triple Fi's as I got rid of them last year but from what I do remember, the Go-DAP did reveal a little more of what the Triple Fi's are capable of. I've used the Go-DAP more with my Unique Melody Merlins more than with other IEMs. I didn't notice any channel imbalance in the 8 months of owning 2xGo-DAPs and 2 other loaners from VentureCraft. The same with noise - if anything good recording is probably important.

I'm hoping to be able to get a 3rd loaner from VentureCraft, this time the Go-DAP 4.0 with the AD8066 OpAmp.

To be honest I don't know about Equalizer. But I do know that FLACPlayer works fine through the Go-DAP, and default Apple player's preset equaliser works fine - i.e. not bypassed by the Go-DAP.

From my past experience AKM DAC (Behringer DEQ2496) + Burr Brown OPA2134 (DIY HP amp) did match well, rich mid with detailed highs, but that's with HD650. With the Merlins, what is your gain setting? At what position will be your volume knob?

You're right about the value of amps on the TripleFi vs M-80. IMHO (and I've written it before) that the M-80 is already quite well tuned and I find that it benefits little from DAC/Amps. That's not to say that there is no difference. There is, but it's minor in comparison to some other headphones.

Admittedly on the Go-DAP i listen to it on High gain. But on the upgraded Go-DAP (with the RK73 upgrade), the low/high gain doesn't change that much. Whereas the stock Go-DAP 4.0 the low/high gain makes a bigger difference.

I do listen to things rather loudly so around the 1:30 -> 2 o'clock range.

One can only assume that if the others work so will Equalizer.  Thanks!

I can't remember what I listen to it on my M80. I just sold it off to my friend 'cos ever since I got my Merlins, I actually stopped taking the M80 out. On my Ultrasone Ed8's probably around the 2 o'clock (starts from around from 7 o'clock - I have to state this 'cos the Go-DAP doesn't have a marker on the knob).

to AnakCHAN. It was cool meeting you at the Headphone show. I got to try both VAMP and we have GoDAP here. It is really impressive and does so many things. I listen with VMODA M headphones and at the office with the Q701 headphones and with Fischer Audios FA011. It all sounded very good but not at so high volumes as you.
