CEntrance DACmini DAC/Amplifier Official Thread - Page 76

post #1126 of 1133

further details, I just found the culprit to my hum

 

I had a Schiit sys in between using as a source switch, The mini out went to the in on the sys, the 2 outputs on the sys went to my external headphone amp, and my speaker amp, turns out if I remove the speaker amp the mini is silent

 

so I have a ground issue on the speaker amp which is a cheapo and only uses a 2 prong power cord

 

 

I am just happy I dont have an issue with the MINI :gs1000smile:

 

 

I rarely use the speakers anyway so it no loss, it just made things easy

Connected to the Kenzie Tube Headphone amp and all I can say is WOW, currently doing Dave Brubeck Take Five :L3000:

 

 

something that is really sticking out is the quiet, Everything just seems to appear from nothing...................My bifrost etc were all quiet but this thing is almost eerily quiet

 

 

 

 I feel like the onboard amp is very good and I could live with it, But after the Kenzie warms up there is no doubt it is better

now I am finding where this beats out Bifrost Uber

 

cleaner edges to the individual instruments, better separation yet remains very analog and musical, while Bifrost uber was very good IMHO and was very musical it was not able to reveal the separation like the mini, 

 

I am having a problem putting the sound to words........................the synergy I have here is almost sinful, Absolutely the best I have heard the HE500's sing

 

 

Death Cab for Cutie,  Plans is sublime  I have a long night ahead:beerchug:

It's always nice to see someone having a good time, appreciating their gear!

 

Enjoy!

Plug phones into external amp power it on and I get no hum from the phones

I dont want and dont expect to have to plug in and remove RCA cables everytime I want to use externals


any ideas ??????? 
Sounds like a grounding problem, possibly with the wiring. DACmini's audio ground (RCA connector ground) is isolated from the mains, so it is insensitive to bad ground wiring, but I don't know about the other amp. Check to see that ground is correctly connected in the other amp and not reversed in the power cable - that would be my first guess.

Problem was resolved, I was using the centrance as a dac only through a passive pre to 2 different amps 1. The Kenzie Headphone amp, and 2. a cheap digital receiver which I use to power bookshelves,  turned out the cheap digital was causing the hum

 

I now have it set up to use with the kenzie or the built in amp with no issues at all

 

although the kenzie amp sounds better it does take the normal tube warm up in order to do so, I like just turning on the centrance and have good sound, as a bonus I will save some tube life:wink_face:

Wondering if anyone can lend me their expertise in electronics to help me with hooking up my Dacmini. I recently moved my room around and went to hook up the dacmini up again and it kept resulting in the tripping of the breaker in my home. I had no problems before this and I plugged in all the other essentials before plugging in the power like it is suggested in their website. Is there anything I need to know when setting this up that I might have messed up. Thanks for your help in advance.

If you plug the AC adapter into the power line before it's plugged into the CEntrance, does the breaker trip, or does it only trip when power gets into the CEntrance?
