After hesitating for so long, i finally made the decision to purchase the "musical flavored" dac Audio-gd reference 8.
It should be here within a week or two.
I will draw down some impression and hopefully "long" enough to be a mini review after some listening and A/Bing with ultra micro dac+PSU( i know it's probably not fair to compare the two...）
I am currently using ultra micro dac+ V8p with pinkie and tubes(HP,bugle boy, siemense)+ D5000
However, i am palnning to upgrade my amp and headphone as well before the year end.
Any suggestions on the amp? I am considering upgrading my headphone to LCD-2 balanced or LA7000.
For amps, maybe HR BUDA or WA22?
Anyone who purchased audio-gd ever received receipt or warranty card?
DAY 1 Impression:
i turned it on for around 3 hrs and the sound is much more balanced. maybe this is also due to the fact that i changed my siemense e188cc tube to HP tube. siemense e188cc tube really extends the highs and lows with bigger soundstage but also sends the mids backward.
if i was to describe the sound before warm up and tube switch, it was like a whole or a tunnel in the sound, i haven't heard of a tube dac or amp sound, so maybe that was it? and also it IS more DYNAMIC but bit too crowded(lots of instruments everywhere), not very smooth, hopefully burn-in will make it smoother. A lot of bass, rich bass, uncontrolled, flooded. I am using D5000. Airy. I just hope mids can be a bit more forward and higher mids can be just a little bit thicker.
please do excuse me for the messy impressions as i am just drawing down my impressions along listening. actually, my D5000 sounds more like a speaker, my logitech z2300 with 6.5inch subwoofer. gee,it's making my d5000 mad!!!it's exploding,bombs throwing to me face!!!! Bass was not that thick and wide with ultra micro dac. It reminded me of those disco halls.
warm sound,not bright.
I guess i will leave it on 24/7 for a whole week.
DAY 2 Impression:
I've had it on since last night which has been 24hrs.
As i listen to more songs, highs are harsh, but probably will gone after burn-in.
Soundstages are widen, i finally found the wide soundstage I listened to at BOSE outlet which i would never forget using a comfort5.
Day 4 impression:
i've left the power on since first turned on, the case is pretty hot. tried some mp3s with less than 320 rates,no good~although kingwa describes as forgiving for bad recording and file, still, it reviewed weakness of those mp3s. suggest listen with lossless, or at least 320k.
i found the lower mid to be muddy and forward ruining the whole thing.hope it will disappear as time goes by.... it's only day 4.
Day 5 impression:
This is incredible!! turning the volume up would would bring day and night change!! more and more details kept poping up and messy crowdy feeling when listening with relatively low volume were all gone! left with huge soundstage and great smoothness, absolutely enjoyable! mids vocals are also more forward
