Lol you are correct sir! :wink_face:

 

Also, this is the case/PSU I am using. It's pretty obvious that it's a sorry excuse for a PSU lol.

EDIT: I apologize for going off-topic, but hopefully others find the info useful. I too am interested in this DAC though!

Thanks for the info. Yeah that linear PSU is just too expensive for the purpose it serves. I believe I only require about 40w. I too use a low power 4th gen Intel CPU, with low voltage RAM and green drives with a mSATA SSD for OS drive. The problem is that the PSU is not standard ATX size, it's about half the size and I'm not sure what that standard is called. 

 

So, you recommend a Pico PSU fed by a 12V linear regulated PSU? Would just any DIY version be fine or do you find large differences in regards to quality?

 

Thanks,

Brunk

Hi Brunk,

 

Any psu with the right specs for the PICO will be fine, however my friend upgraded from a standard power brick to the linear PSU mentioned above and was very happy with the change to the SQ of his rig.  Please know his PC is solely setup for music playback and the rest of his chain is also at a high level. (Usually I want to rip the HD800's off my ears as I find the treble a bit too much - on his rig they sound pretty damn good!) The PSU he is using would be around $250 in parts (I'm guessing, a diy friend put it together for him, not a commercial product)  but the builder has stressed that a cheaper linear psu, may not be worth it - apparently just because it's linear doesn't mean it's good, or will have the desired effect in a audio system.

 

I just thought I would mention this stuff as Greed was asking about the iUSB and getting the best out the 777.  A few of my friends (IRL) have done similar build lately and all have been impressed with the outcome in their system.  Also there is a fair bit of information on the JPlay forum in regard to Audio PC building + PSU's for PC's, if you are happy to do a bit of research..  There are also some "lab" style PSU's available from EBay which people on the JPlay forum say work pretty well.

 

Cheers,

 

gav.

I can imagine the AMR is a huge step up from the Yulong! :)

Hey Greed -

 

What were your impressions of the MSB Analog vs. the 777?

post #110 of 356

Thanks again Gav. I will visit the JPlay forums and do some research, along with finding a good design for a linear PSU :) Yes, I do think the AMR would be a nice step up from the Yulong, I only wish there were a way I can audition it beforehand.

Ugh...I have visited that site several times before. While there are a select few articles that are great resources, the total dominant theme there is misinformation with poor souls feeding out of manufacturers hands. Blunt, I know.

Fair call, there are some good posts there but I agree with the manufacturer comment.

Hi Hun7er,

 

Apologies for the late reply -

 

I have just had the upgrade performed.  The distributor came to my house and swapped the board out for me.  Not too big of a deal - the board that is replaced is on risers above the main board on the bottom of the unit. 

 

I have been told that the upgrade will be $1000US and that the Australian market was used as a test for the upgrade procedure.

 

Thanks,

 

gav.

Hi don't worry,

 

So it will comes on the new DP777 ?

post #116 of 356

So I have been doing some A/B for the past two days between the MSB The Analog DAC vs AMR DP-777. Sorry for those that have asked for a comparison, I've been busy with the regular holiday stuff, you know how it is. I believe I can firmly say that after listening to these back and fourth that the MSB is still a league ahead in most areas. On first listen, before really getting into the music - my initial thoughts were that the AMR is very close in performance to the MSB. Sadly I was mistaken. Now that I've had some time to switch between the two the difference is noticeable and apparent to my ears. The entirety of the test was done through speakers, but I plan to try out my headphones today, so again sorry for the delay but I'll have some time to write some notes and report back. Luckily I wrote some notes when the GSX mk2 was still in house so I can share that as well.

For speakers atleast, though that usually translates to headphones too, but not all the time.
