In that case I should have just kept the much cheaper iPod classic and bought an amp/dac which would have been cheaper haha.

eh, i mean im using the Iriver ihp-140 And using the ibasso DB2 with custom sys-concepts fiber optic cable.

 

i get what your saying, but i also feel there is something to be gained by using fiber optics...i believe only the astel and kern and the iriver ihp-120 and 140 are the only daps with optical outputs, well iriver and astell are both from iriver

I don't really know enough about the technicalities TBH. All I know is I bought the RWAK100 with the understanding it was a great DAP with  excellent digital to audio conversion, and that I could pair it with an amp to go balanced. I was tossing up between doing this and keeping the ipod and buying both a DAC and amp.. but decided I liked the portability of the small DAP and a small amp like the SR71b.

Not really, I didn't spend the money on the AK100 just to bypass the DAC, seems a bit of a waste.


Is the dilemma I faced when looking for an amp for my AK120, was going to opt for the Hifi M8 and go optical out but seriously, people are better off using a decent source player if they're going to spend so much on a device with bells and whistles just to bypass the whistles... the M8 has no analogue in, am now considering the Ibasso amp vs the ALO MIII to go balanced.

well essentially at least currently no DAP has all the ''bell'' and ''Whistles'' or clearly there would be no want to pair a dap with the likes of the sr-71b...clearly the amp section of any dap isnt going to be on par with the sr-71b, this can also be said for the dac sections. and im generally talking about daps in general, not any one dap in particular.

 

for portability daps that have higher end audio components are going to best suite portability, but does one look at a dap say count only the amp and dac section as the bells and whistles? if not then there seems to be room to source a higher end amp and dac section and use the dap as a high end media carrying device.



Sorry just curious if anyone with a ak100 or 120 was using the optical options. I see it from all angles

Honestly, I buy DAPS for the Dac, anything that doesn't have a line out is ignored. I like my HM801 because it's got a LOT of tech surround it's dac, it has line out, as well as Coax and USB in all to that dac! And imo it sounds awesome! It does circles around my old oDac, I just need a better amp for it :3 hoping the sr71b will be that amp

The pride and joy of the $1000 AK120 is in its twin DAC in comparison to the AK100's single channel DAC... if you're bypassing that section, then why the $1000 AK120? If its only to be used as a source player then the difference between the two isn't there... if you're going that far you may as well look at other DAP's with decent line outs knowing that your Amp/DAC will be the section to clean up the audio signal.

 

Am not highly educated in audio gear etc but am having the same discussion in the AK120 thread, it all boils down to what chip set is featured in the DAC you're actually using, if the chipset used is of a lesser quality than the one featured in the source player you've bypassed then you're downgrading the signal and are better off with an amp on its own.

Don't forget the ibasso DX-100.

 

I'm using both the DX100 or ihp-140 to an external DAC.  The quality is way beyond what can be achieved in a single box solution.  The reason to get a high end player is for when you're on the go...you can get close to the component system quailty without the fuss and extra hardware.

I still don't understand the reasoning behind feeding a $1000 player into a seperate dac... I mean honestly that seems assine, as others have mentioned. Does no one make essitanally an EPIC GUI Player with a Usb port? Seriously... maybe I ought to tinker with getting a tiny little Win 8 Tablet to work with USB Spdif out... as I to feel that if I'm paying $500 for it, the Dac better be damn fine!

What chipset is in the DAC devices you're using and does it outdo the twin converters in the DAP's mentioned..? Am sure the Dx100 has twin channel converters... AK100 has single.

 

That's the crux of the matter, myself and others are questioning whether or not people might be downgrading the signal quality using inferior conversion processes by bypassing the expensive dual converters found in many high end source players... in which case its only an amp people need not another Digital Analogue Converter.

I would think the RSA balanced Dac would not be a down grade... it may not be as transparent but it's a balanced dac so your going to get better sound stage and imaging for that reason. And I highly doubt the Dacs are THAT big of a differenace at the $700+ point. Aside from Wolfson vs ESS Sabre vs PCM ect... which are personal color choices or lack of color choices

 

anyways... how is the treble on this amp... I'm thinking of getting this, MOSTLY for my w1000x which could use a dark amp [dark but still transparent... I hate HATE warm amps... I like slighty dark] ANWAYS

 

I'm really wanting a MD 3.2 Balanced for my POrtable EDM needs, I HATE me HE 400 for ANTYHING outside of EDM... and honestly when I had the MD it was teh same feeling. Both the MD and HE 400 where are are excellent for edm SO I figured why not use them just for EDM [seeing as half my music is edm] so that said, how is the treble on the SR71B. I like bright or hot treble, the w1000x could be mellowed out treble wise BUT the MD needs a treble boost imo... so not sure if I would wnat to use my pb1 or the new and to be aquired sr71b

Is that safe to do? I thought it wasn't that safe to connect a single-ended termination -> balanced adapter due to the lack of grounding. Does going from 1/4'' -> mini-XLR -> ALO/RSA Kobiconn mini-balanced add a DC ground or no?

 

I've been wondering on how to go about attempting to either re-cable or find proper adapters (if at all possible) to use the balanced Kobiconn headphone out for my Grado HP-2s, but idk honestly.

very true.

 

i do find the iriver ihp-140 to be a excellent sounding dap even for its age. imo it was really a innovation in digital audio players given the fiber optic i/o... giving you the ability to bypass the amp and dac using fiber optics, i think it came out in like 2003/4

you can tell it was a dap ahead of its time considering the ak100 and ak120 use the same type of foundation as far as the line out fiber optics i/o

 

i do agree that on the go the dx-100 and ak100/120 are excellent daps but for home use using a external dac and amp i feel higher audio quality can be achieved,

 

im using the iriver ihp-140>sys-concepts custom fiber optic cable>ibasso db2 dac>toxic silver poison rsa male to ibasso hirose male>RSA SR-71B>Toxic silver poison cable balanced> westone w4r

 

i found find it hard pressing to get a full on the go dap that can put out the kind of sound quality i get from it, true its not a portable but more like a portable home system

Yeh... am going for the RW balanced mod on the AK120 and have decided to start making cables for various ams etc... Red Wine sell a TRRS to Kobiconn cable but its easy enough to make and I'd no doubt need other connectors also so its to the soldering iron for me.

interested to see your adapters when done,
