Well I'm using Gustard U12 for USB to Coax converting. It is really good for its money. And it has a small screen for sample rate. If its expensive for you, you can check other DDC solutions. And I agree with @Soundsgoodtome about USB noise. You should use either a usb reclocker or a DDC to...

  I'm using Atlantis, and i can say if you want to use it via USB input, you should have a seperate computer for playback only. Its USB input is too picky. (My desktop cannot feed it properly, but a seperate entry grade laptop with empty task manager can feed it.) Or you can buy a usb...

Btw guys, earlier i mentioned about a electrical hum from Atlantis. As it turns out its because bad distrubution of electricity of the apartment. My room's outlets share switch with another room. I tried my system at my friend's house and there was no hum. I'm getting seperate switch for my...

  I made the Ep-507 upgrade (SR-507 pads) recently. They are really softer, and ofc more comfortable. And they're not only a comfort upgrade. Imho, they help with subbass region, and a bit tamer highs. They are warming SR-207's sound a bit.

  My amp is Srm-252s, currently working with a walwart. There was no humming issues with my other dacs but they were working with either usb power (HRT MS II+) or power supply (Smsl M8). It might be due to poor powering. Cuz i have one outlet in my room and all my devices gets power from it.  ...

    Hum noise diminishes as it keeps working, with ot without recieving signal. Yes it has the hum with all of my tubes. Btw if this information helps identifying the problem: the sound of hum sometimes increases and decreases quickly.   Like: MMMMMMMmmmmmmMMMMmmmmmmmmmmmmm

Hey guys, I have a question for you.   I have Atlantis dac. When it's powered up, it starts with hum noise (low level 50-60 hz noise). The hum diminishes by time. Hum exists only when there is no signal. When a song starts to play it ceases humming.   Is it normal for a tube component? or is...

Hey guys, i have a problem with my Gustard U12, and since main thread of it is closed, i wanted to ask on this thread.   My Gustard U12 have slight mechanical hum. Not carried through audio chain to my ears but its power supply (i guess) making audible noise when it's powered up. Is it a...

  Srs-2170 is really quiet. I dont know what you meant exactly as saying noise but, bad walwart can bring noise, if your dac has loose transformer inside; it can bring noise, bad usb connection (fed problems, a lot of device to weak computer, etc) can bring noise. Srm-252s can pick and bring...

Hey guys, I want to buy a laptop or 2in1 for using just for transport pc. I want it small (11,6 or 10,1 inch) and quiet. I mean i dont want any mechanical disk and fan. I'll just use it with foobar 2k. And it must be around 300 dollars.   I'll feed transport ddc with it.   Thanks for all...

My new board came. Jiun is extremely helpful guy. I just installed it and it works flawlessly so far.  

My problem is about microcontroller chip as Jiun diagnosed. Btw I always power up computer first. sometimes when I power up no lights blink and only tube gets powered.

    Well luckbad, when i mentioned my problems to Jiun, he immediately offered board replacement on the house. I'll try it first. I also get a cheap (musiland us 02) ddc too. My computer is multitasking, most probably best solution is getting a ddc anyway. :) btw while deciding buying it, i...

Hey guys, i recently joined the club by buying Atlantis. Thanks to @Soundsgoodtome :) This Topic is for havana originally but i guess it became main topic for Mhdt Lab as time passed.   Anyway, I discover a problem with my new dac, it's usb keeps disconnecting, and sometimes when i power up...

Sure, you should use it first, try it out and hear the sound. Fiio makes good products for their price.   What i wanted to mean is; you'll get really good improvements with source upgrades, interconnect upgrades. As you try and try.
