Is it worth replacing a Lumin D2 with an Eversolo dmp-a6 Master Edition?
In my opinion, streamer is depends on its hardware and software/firmware, most important is the good support and after sales service in the long run.  If you are satisfied with your current streamer and its firmware stability, just stay with it.  ... 
Broken banana plug and stuck in amplifier
Many thanks for all your suggestions and safety precaution. I managed to use tweezer to slowly and hold tight on the tip of tweezer to pull out gently without damaging the terminal (the broken banana plug tip was split in loose, so use tweezer to... 
Denafrips FPGA Firmware Update
Has had the FPGA firmware updated over the last weekend, the change of sound is obvious after auditioning for days, a critical audition with familiar tracks , music instruments are well separated, precise with clarity.     I am able to listen fo... 
S/N ratio Balanced input vs. Unbalanced input
@atmasphere What you said make sense. I will leave it if this not a defect, just not perfect.  Thanks   
S/N ratio Balanced input vs. Unbalanced input
Are you sure other sources into the amp don’t give the hiss? @o_holter Ya, I tried my old Sony CD player which connect to integrated amplifier via RCA, I did not notice any hiss near tweeter.  I will do fast "switching" from balanced input (Are... 
S/N ratio Balanced input vs. Unbalanced input
No more hiss if DAC is disconnected  
S/N ratio Balanced input vs. Unbalanced input
@o_holter yes, the hiss is constant, with no variance on volume, the hiss is there with power standby on my DAC Ares II , only it’s gone when I unplug the power cord  
S/N ratio Balanced input vs. Unbalanced input
Can you hear it from distance of 1m? @kijanki Nope, only audible at near field,  close to tweeter. If this is not abnormal, then I am relief. Auronthas - can you compare the hiss, changing to single ended input? @o_holter since my Ares II ... 
S/N ratio Balanced input vs. Unbalanced input
@kijanki the reason I ask is I can hear noise (hiss) from tweeters when my balanced input (Denafrip Ares II) is connected while music is stopped playing. Volume changing not affected the hiss sound.   
S/N ratio Balanced input vs. Unbalanced input
@kijanki I just check E270 vs E260 technical paper, E270 noise voltage is 35microV at -30dB volume position But in the above E280 technical paper, E270 noise voltage is 41 microV. I am more confused now. https://www.google.com/url?sa=t&sou... 
S/N ratio Balanced input vs. Unbalanced input
@kijanki Thanks for pointing out. I hope so. But, when i checked the previous model E270, the S/N ratio for balanced input is 91dB, unbalanced input (high level input) is 108dB.   I am confused.  
What cause tweeters hiss ?
One thing to note ... my old Cardas XLR cables are longer 2m each,  new one is 1m.  A longer XLR cable may subject to noise interference than shorter one.  Also the 15 years old XLR may not have a good shielding against WIFi ... perhaps. Some of ... 
What cause tweeters hiss ?
I do check and isolate one by one interconnect  as well audio equipment connected to my integrated amplifier .  As for Ares II, it was not recommended to have both RCA and XLR to be connected due to the R2R design with high output impedance.  Thus... 
What cause tweeters hiss ?
@oldrooney hi, thanks for your detail explanation on the XLR pin terminals construction,  i am not electronic savvy, and furthermore this XLR interconnect may have reached its life span after 15 years ? I will leave it, lucky that I have a spare X... 
What cause tweeters hiss ?
@itsjustme @perazzi28 @oldrooney @gs5556 @jb1 @clearthinker @erik_squires Dear all, thanks for your advise and sharing thoughts. Finally I have discovered the culprit, it’s my 15 years old Cardas XLR interconnect. (even I have had tried phase inv...
